Did You Know Poor Sleep Can Trigger Weight Gain Hormones Overnight

Introduction

You literally did everything you were always told. Tried eating clean, did strength training, fixed sleep schedule and yet after all of this, something always felt off.

Your periods were still irregular, energy dipped rapidly, weight didn’t respond the way it was supposed to and somewhere along the way, you were constantly told you might have PCOS. But even that diagnosis didn’t entirely explain what you were experiencing because deep down, it never felt like it was just about your ovaries. And now finally after years, for the very first time medicine is catching up with that reality. 

PCOS has officially been renamed PMOS which stands for Polyendocrine Metabolic Ovarian Syndrome. 

This entire shift from pcos to pmos is more than just a change in the name. For your information it’s a complete reframing of how you understand this condition. And most importantly, it is finally being validated what women have been saying for years and years. 

PCOS Renamed PMOS

Why does this change even matter? 

After a global consensus including around 14,000+ women and about 56 business organisations, the term PCOS was reconsidered. Because the board finally concluded stating that the name itself was misleading.

The breakthrough of PMOS is as follows:- 

PMOS is referred to Polyendocrine Metabolic Ovarian Syndrome

• Polyendocrine means multiple hormone systems are involved
• Metabolic related to insulin resistance at the core
• Ovarian redirects to the reproductive symptoms

Earlier, pcos pmos was understood largely just as an ovarian issue.

But in reality pcos and pmos are whole-body conditions. They involve factors such as metabolism, inflammation, hormones, stress, as well as gut health. This is exactly why the shift from pcos renamed pmos is so significant. It moves complete focus from symptoms to systems.

You Don’t Need Cysts to Have PCOS (or PMOS)

One of the biggest misconceptions around pmos and pcos is that you need cysts to be diagnosed but in reality you don’t. 

Many women with pcos pmos:

• Have clear ultrasounds
• But still experience symptoms 
• And still meet diagnostic criteria

But always know diagnosis can still come from factors like irregular or absent cycles, elevated androgens (testosterone, DHEA-S), along with signs of insulin resistance

So if your scan was “normal” but your symptoms weren't, trust me when I say your  experience is still valid and in fact worth investigating. 

The “Cysts” Were Never Really the Problem

Here’s something most of you aren’t told. Those “cysts” seen in PCOS? They are not actually cysts. They are immature follicles which are the eggs that didn’t fully develop due to hormonal imbalance.

This clearly states that the ovaries are responding to a deeper issue but they are not the root cause. And this is exactly what pcos to pmos helps in clarifying. 

The Real Root Causes Behind PMOS

At iThrive, we don’t ever really stop at labels like pcos and pmos. We have always known in the nutrition field for going deeper into why exactly your body is responding the way it is.

1. Insulin Resistance

This one is the big one. Somewhere between 50–70% of women with PMOS have insulin resistance at the core and most of them have no idea.

Here's what's actually happening: when your cells stop responding to insulin properly, your body compensates by producing more of it. And excess insulin directly tells your ovaries to produce more testosterone. More testosterone means disrupted ovulation, more fat storage, more cravings and suddenly you're in a loop that no amount of clean eating seems to break.

That frustrating feeling of doing everything right and seeing no results? This is usually why.

2. Chronic Low-Grade Inflammation

When I say inflammation in pcos renamed pmos, I don't mean the kind where something visibly hurts or swells. This kind is invisible. It's quiet. And it's been running in the background for years.

At a cellular level, chronic inflammation keeps your body stuck in a constant state of alert. It stimulates the cells in your ovaries to produce more androgens. It makes your insulin receptors less responsive. It raises markers like hs-CRP and IL-6 that most standard blood panels don't even bother checking.

And you would like to know the worst part? It feeds itself. Inflammation disrupts hormones, and hormonal imbalance drives more inflammation. Round and round.

The triggers are usually coming from processed foods, a compromised gut, environmental toxins, or chronic stress. Which means until inflammation is actually addressed at the root the pmos symptoms keep coming back.

3. Stress & HPA Axis Dysfunction

We've all been trained to think of stress as a mindset problem. But physiologically, stress is a hormonal event and a serious one.

Your HPA axis is your body's central stress response system. When it's chronically activated, cortisol stays elevated. Elevated cortisol destabilises blood sugar, which increases insulin demand. And your adrenal glands start pumping out androgens like DHEA-S independently of your ovaries.

This is where it gets interesting. Even if your ovarian hormones look completely normal on paper, adrenal-driven androgens can still cause acne, hair thinning, and irregular cycles. This subtype that is adrenal pmos is especially common in women with high-pressure, high-performance lifestyles. And it gets missed constantly because nobody's looking for it.

The HPA axis is the central stress response system of your body. When it is activated repeatedly, it starts affecting multiple pathways that are involved in pcos to pmos progression.

4. Gut Dysbiosis & Leaky Gut

Your gut is deeply connected to your immune system, hormones as well as metabolism. 

In pmos pcos, gut dysfunction often shows up as reduced microbial diversity, increased intestinal permeability also known as leaky gut, and overgrowth of harmful bacteria. This results in something called metabolic endotoxemia wherein the bacterial toxins like LPS leak into the bloodstream.

So what do they do?

Firstly they trigger the systemic inflammation, secondly it worsens the insulin resistance and lastly it disrupts estrogen metabolism through the estobolome. 

The estrobolome which is the gut bacteria that is responsible for the procession of estrogen plays a significant role in maintaining hormonal balance.

When it’s compromised even slightly, it leads to affected estrogen clearance, worsened hormonal balance, and intensified symptoms of pcos and pmos. 

This is why many women with pcos renamed pmos also report:

• Bloating
• Constipation or irregular bowel movements
• Food sensitivities

5. Nutrient Deficiencies

This is by far one of the most underestimated drivers of pcos pmos. Because most of you including our clients who came to us initially assume that if you’re eating well, you wouldn’t be deficient. 

But always remember nutrient sufficiency ≠ nutrient absorption.

In pcos renamed pmos, deficiencies are extremely common due to factors such as poor gut absorption, maximised metabolic demand, chronic inflammation and stress related depletion. 

Let me take you deep into the key nutrients:

Vitamin D

Vitamin D acts like a hormone, improves insulin sensitivity and also regulates the function of ovaries. 

Low levels of Vitamin D are strongly linked to insulin resistance and irregular cycles. 

Magnesium

Magnesium is required for around 300 enzymatic reactions, it supports glucose metabolism and also calms down the nervous system. 

Deficiency can worsen to insulin resistance and stress response.

Zinc

Zinc is critical for the functioning of ovaries, as it helps reduce the activity of androgen and also supports skin health. 

Low zinc often shows up as hair fall as well as acne.

B Vitamins

B vitamins are essential for production of energy, it also supports hormone detox pathways and helps in regulating mood. 

Inadequate levels can slow down the metabolic processes and further affect ovulation.

So basically besides a “healthy diet,” your body still needs smart supplementation. 

6. Environmental Toxins

This is exactly where the modern lifestyle silently interferes with biology.

Endocrine Disrupting Chemicals (EDCs) such as:

• BPA (plastics)
• Phthalates (cosmetics, packaging)
• Heavy metals (mercury, lead)

…can mimic or block natural hormones.

In pmos and pcos, this becomes particularly problematic because these chemicals bind to the receptors of hormones. Then they alter the pathways of signalling further disrupting the feedback loops between ovaries, brain, and metabolism. 

Over time what happens is the body loses its ability to regulate hormones efficiently. Additionally, toxin exposure increases oxidative stress, burden of liver detox, and inflammation which further worsens the progression of pcos to pmos. 

None of these causes exist in isolation. What you see in pcos pmos is an interconnected web of all the mentioned factors and treating just one symptom never really works. Therefore pcos renamed pmos is such a necessary shift. 

PCOS PMOS is a multi-system imbalance, and not a single-organ disorder.

The 5 Functional Types of PMOS

Not all pmos pcos is the same.

Functional medicine identifies 5 types:

1. Insulin-Resistant PMOS

Most common which is majorly driven by poor blood sugar control.

2. Adrenal PMOS

Triggered by chronic stress and high cortisol.

3. Inflammatory PMOS

Linked to gut issues, food sensitivities, and toxins.

4. Post-Pill PMOS

Occurs after stopping birth control.

5. Hidden PMOS

Triggered by factors like thyroid dysfunction or nutrient deficiency.

Understanding your type changes everything about treatment.

Symptoms You Shouldn’t Ignore

Pcos and pmos don't always look obvious.

It can show up as: 

This is why pcos renamed needed a broader lens.

What You Should Actually Test

Instead of guessing, look deeper:

• Fasting insulin
• HbA1c
• Testosterone & DHEA-S
• LH:FSH ratio
• Thyroid panel
• Inflammatory markers

Book Root Cause Analysis to identify your specific triggers or if you want clarity instead of trial-and-error

Because pmos and pcos are never one-size-fits-all.

How iThrive Approaches PMOS

We have around 8 years of experience in the functional nutrition field, we’ve seen endless clients but one thing that we swear by right from the start is that we don’t just manage symptoms, we decode systems.

Our Alive Programme revolves around three factors that are personalised diet protocol, smart supplementation and lifestyle interventions. Because the goal has never been suppression it has always been reversal. 

Key Takeaway

For years, most of you have been told to just lose weight, everything is normal, acne would disappear, and that this is common. But now, with pcos renamed pmos, the narrative has finally and for once changed. Because your body was never confused, it was always communicating.

Each and every symptom, the fatigue, the irregular cycle, and the sweet cravings were a signal. And now that we finally understand pcos and pmos the way it was always meant to be understood.. you’ve got a choice. 

Either to ignore it again or to finally listen and book a root cause analysis to know the triggers so we start reversing as soon as possible. Because healing doesn’t begin when symptoms disappear. It begins when you start understanding what your body has been trying to tell you all along.

Introduction

Picture a 28 year old woman in India. Her periods have been irregular for over a year. She has been told she probably has PCOS. Her thyroid panel came back normal. She has been put on birth control to regulate her cycle, but the moment she stops, the irregularity returns. Nobody has checked her prolactin yet.

This is not a rare story. Research shows that between 25 and 37% of women presenting with unexplained infertility have elevated prolactin levels, yet a prolactin test is still not universally included in early hormonal workups.

Hyperprolactinemia, chronically elevated prolactin, is one of the most underdiagnosed hormonal disruptions in women of reproductive age. It derails periods, blocks ovulation, feeds mood instability, and creates a confusing symptom picture that points in every direction except the right one.

How Common Is This? The Numbers That Should Alarm Us

Before diving into symptoms, it is worth pausing on how widespread this condition actually is in India.

That last row is particularly striking. In a 2025 Indian study of 110 women with PCOS, over half had hyperprolactinemia. These are not numbers from a rare endocrine condition. They are the everyday hormonal reality of Indian women.

What Is Hyperprolactinemia and Why Does It Hit Women Hardest

Prolactin is a hormone made by the pituitary gland. Its primary role is to trigger breast milk production after childbirth. Outside of pregnancy and nursing, prolactin should stay low. When it rises without a biological reason, the consequences are significant because prolactin directly suppresses FSH and LH, the two hormones that govern the menstrual cycle.

When prolactin climbs, FSH and LH fall. When FSH and LH fall, ovulation stops. And when ovulation stops, the period disappears or grows erratic. This is the central mechanism driving hyperprolactinemia symptoms in females, and why the period is always the first thing to go.

Women carry a far greater burden of this condition than men. The female hormonal system is simply more sensitive to prolactin fluctuations because the reproductive cycle depends on getting it right.

‍Hyperprolactinemia Causes: What Is Actually Driving Your Prolactin Up

The cause is not always the same and treatment depends entirely on finding the right driver.

Prolactinoma

The most common structural cause is a prolactinoma, a benign pituitary tumour that overproduces prolactin. These account for nearly half of all pathological cases and are more common in women than men. Women typically develop smaller microprolactinomas that are harder to detect on routine imaging, which is one reason diagnosis is so often delayed.

Hypothyroidism

When the thyroid is underactive, excess TRH directly stimulates prolactin secretion. A woman with poorly managed hypothyroidism may have elevated prolactin purely as a downstream consequence. Treating the thyroid often normalises prolactin entirely, without any direct prolactin intervention at all.

Medications

Antipsychotics, certain antidepressants, blood pressure medications, and antiemetics raise prolactin by blocking dopamine, the brain chemical that normally keeps prolactin suppressed. This dopamine connection is central to understanding the condition and why nutritional support can genuinely make a difference.

Chronic Stress and Sleep Disruption

Prolactin rises with physical stress, poor sleep, and sustained high cortisol. Women who are consistently overworked and under-rested often carry mild to moderate prolactin elevation that nobody connects to their symptoms. The overlap with burnout is real. Read our blog on Addison's Disease Symptoms in Women Mistaken for Burnout for a fuller picture of how stress-related hormonal conditions disguise themselves.

Hyperprolactinemia Symptoms in Females: What Your Body Is Saying

Prolactin and Irregular Periods

The relationship between prolactin and irregular periods is direct. Elevated prolactin suppresses GnRH, which reduces FSH and LH from the pituitary. Without these signals, the ovaries do not ovulate. Periods arrive late, become very light, or stop entirely. The cycle irregularity is the symptom. Elevated prolactin is the cause.

Galactorrhea: Milk Without Pregnancy

One of the more startling high prolactin symptoms in women is galactorrhea, the spontaneous production of breast milk in a woman who is not pregnant or breastfeeding. This occurs in roughly one third to half of women with hyperprolactinemia. Many women notice it and stay silent, assuming it is normal. It is not. It is a direct sign that prolactin is biologically elevated and active.

Prolactin Fertility Problems

Elevated prolactin blocks ovulation and therefore blocks conception. Women who have been trying to conceive for over a year with irregular cycles should have prolactin tested as a first-line investigation. In Indian infertility studies, elevated prolactin was found in nearly 37% of women with endocrine-related infertility. Prolactin fertility interference is one of the most treatable causes of anovulatory infertility once properly identified.

Mood Shifts, Low Libido, and Brain Fog

Elevated prolactin suppresses estrogen, and low estrogen drives depression, poor libido, brain fog, and emotional flatness. Women describe a version of themselves they do not recognise: disinterested, flat, and disconnected. These are biological symptoms, not character changes. Some are placed on antidepressants that raise prolactin further, quietly worsening the very hormonal environment they are trying to correct.

The Dopamine Connection: Why This Is a Brain Chemistry Problem Too

Prolactin secretion is controlled primarily by dopamine, which is released continuously from the hypothalamus. Dopamine truly suppresses prolactin. When dopamine falls, prolactin rises promptly. This is not just pharmacology, rather it is nutritional biochemistry.

Dopamine synthesis requires tyrosine, vitamin B6, iron, and zinc. When a woman is chronically stressed, nutritionally depleted, or sleeping poorly, dopamine production suffers and prolactin climbs. Lifestyle and nutrition are not optional extras here. They sit directly at the root of the mechanism.

Think of dopamine as the valve and the prolactin as the water. When the valve is strong enough, the water stays controlled. When it weakens, everything overflows.

Hyperprolactinemia Natural Treatment: The Nutritional Foundation

Medical treatment through dopamine agonists is the clinical standard for prolactinomas. But for women with idiopathic or mildly elevated prolactin, targeted nutritional support can produce meaningful change. Hyperprolactinemia natural treatment is not a replacement for medical investigation. It is the biological foundation that makes any treatment more effective.

Vitamin B6

Vitamin B6 is a critical cofactor in dopamine synthesis. Studies have shown that B6 supplementation can minimise elevated prolactin in women with idiopathic hyperprolactinemia. Without adequate B6, the enzymatic step that converts tyrosine into dopamine cannot complete efficiently, and prolactin suppression weakens over time.

Zinc

Zinc plays a direct role in regulating pituitary function as well as prolactin release. Zinc deficiency impairs dopamine receptor sensitivity and has been linked to elevated prolactin. Women experiencing hair thinning or acne alongside cycle irregularity should have zinc status assessed as part of their hormonal investigation.

Hyperprolactinemia Diet: What to Build Your Plate Around

A hyperprolactinemia diet is a rebuilding plan, not a restriction list. Prioritise tyrosine-rich foods: eggs, chicken, nuts, and seeds. Add magnesium-rich foods like pumpkin seeds for dopamine receptor support. Include vitamin C rich fruits and vegetables to reduce oxidative stress at the pituitary level. Stable blood sugar is non-negotiable since cortisol spikes directly drive prolactin upward. Avoid alcohol, excessive caffeine, and ultra-processed foods that disrupt hypothalamic signalling.

What Actually Confirms Hyperprolactinemia

Diagnosis begins with a fasting morning serum prolactin test, drawn at least 2 hours after waking and before any physical exertion. A single elevated reading is not sufficient for diagnosis. A second confirmatory test is needed before any treatment decision is made.

If prolactin remains elevated, a pituitary MRI is ordered to check for adenoma. Thyroid function and medication history are reviewed simultaneously. Finding the root cause, rather than simply suppressing the number, determines whether treatment will hold.

If you are experiencing irregular periods, unexplained infertility, or mood disruption alongside cycle changes, a root cause analysis can map the full hormonal picture rather than treating each symptom in isolation.

Key Takeaway

Hyperprolactinemia is not rare. It is one of the most common hormonal conditions in Indian women of reproductive age, hiding behind missed periods, unexplained infertility, and mood changes written off as stress for years.

A single prolactin blood test can begin to change an entire diagnostic story. Whether the driver is a pituitary adenoma, an underactive thyroid, B6 and zinc deficiency, or chronic dopamine depletion, this condition has clear mechanisms and clear pathways of support. It goes undertreated not because it is complex, but because it goes untested.

If your hormonal picture feels incomplete and the standard answers are not adding up, do not wait. Book a consult and let the right investigation finally begin.

Introduction

For many people living with fibromyalgia, the experience goes far beyond occasional pain. It often feels like the body has lost its internal energy system. Simple daily activities become exhausting, muscles feel persistently sore, and concentration becomes difficult. Many individuals describe waking up already tired, even after what should have been a full night of sleep.

This is why fibromyalgia chronic fatigue is one of the most frustrating aspects of the condition. Patients frequently report that the exhaustion feels deeper than normal tiredness. It is not the type of fatigue that disappears after rest. Instead it persists for months or years, creating a cycle of low energy, pain, and mental fog.

For decades fibromyalgia was largely misunderstood. It was often described simply as a pain disorder, or in some cases dismissed as a psychological condition. Modern research now suggests a much deeper biological story. The condition appears to involve fibromyalgia nervous system dysfunction, altered pain processing in the brain, mitochondrial energy disruption, and chronic low grade inflammation.

At iThrive Alive we frequently observe that fibromyalgia symptoms rarely begin at the level where they appear. The pain felt in muscles and joints often originates from deeper biological disturbances involving energy metabolism and neural signaling.

Understanding this hidden biology can help explain why fibromyalgia is so exhausting and why addressing root causes may improve recovery outcomes.

Understanding Fibromyalgia Beyond Pain

The Role of Central Sensitization

One of the most important concepts in fibromyalgia research is fibromyalgia central sensitization. This term describes a state where the nervous system becomes excessively sensitive to normal sensory signals.

In a healthy nervous system, pain signals are carefully regulated by the brain and spinal cord. However in central sensitization the brain amplifies incoming signals. Stimuli that would normally feel mild can begin to feel painful.

This helps explain why individuals with fibromyalgia may experience pain in multiple parts of the body even without clear injury. The brain essentially becomes a volume amplifier for pain signals.

Researchers have also observed that this hypersensitive state can affect other sensory experiences. Patients frequently report sensitivity to sound, light, temperature changes, and emotional stress.

This phenomenon illustrates why fibromyalgia hidden symptoms extend far beyond musculoskeletal pain. The condition involves the entire neural processing network.

The Brain Fog Connection

Another common experience among fibromyalgia patients is cognitive impairment, often referred to as fibro fog. This symptom includes memory difficulties, reduced concentration, and slower mental processing.

Fibromyalgia brain fog causes are increasingly being linked to disruptions in brain energy metabolism. The brain consumes a large portion of the body’s total energy supply, and even small reductions in mitochondrial function can impair neural performance.

When cellular energy production declines, neurons struggle to maintain efficient communication. This may contribute to the mental fatigue that many patients describe.

Studies also show altered blood flow patterns in certain brain regions among individuals with fibromyalgia. These changes may further affect cognitive clarity and emotional regulation.

Why Fibromyalgia Is So Exhausting

Many patients ask the same question during consultations. Why is fibromyalgia so exhausting even when physical activity is limited.

One emerging explanation involves mitochondrial dysfunction.

Mitochondria are microscopic structures within cells responsible for producing ATP, the molecule that fuels nearly every biological process. Muscles, nerves, and immune cells rely heavily on this energy supply.

When mitochondrial efficiency declines, cells struggle to maintain normal function. This creates a state of systemic energy deficit that can affect the entire body.

This biological explanation helps clarify the difference between fibromyalgia fatigue vs normal fatigue. Ordinary tiredness often results from temporary overexertion or sleep deprivation. Once rest occurs, energy levels usually return.

Fibromyalgia fatigue behaves differently. It reflects a deeper energy production problem. Even simple physical tasks may feel disproportionately draining because cells cannot generate adequate ATP.

Over time this energy shortage can contribute to chronic fatigue and pain connection seen in fibromyalgia. Muscles lacking sufficient energy may accumulate metabolic byproducts more quickly, increasing discomfort and stiffness.

The Inflammation and Immune Link

Another important contributor to fibromyalgia symptoms involves chronic low grade immune activation.

Inflammatory molecules known as cytokines can influence pain perception and fatigue levels. Elevated cytokine activity has been observed in many individuals experiencing chronic fatigue conditions.

Inflammation can also interfere with mitochondrial function. Oxidative stress damages mitochondrial membranes and reduces their efficiency. This creates a feedback loop where inflammation worsens fatigue and fatigue further amplifies inflammatory signaling.

This interaction between immune activity and cellular energy metabolism may explain why fibromyalgia symptoms often fluctuate during periods of physical stress, illness, or emotional strain.

The Chronic Fatigue and Pain Connection

When mitochondrial output declines and nervous system sensitivity increases, the body enters a state where energy availability and pain regulation both become compromised.

Muscle tissue requires significant energy to maintain normal contraction and relaxation cycles. Without adequate ATP production, muscles remain in a partially stressed metabolic state. This can produce persistent soreness even without physical injury.

The nervous system also depends on energy intensive processes to regulate neurotransmitter balance and nerve signaling speed. When these systems slow down, pain signals may remain active longer than necessary.

This interaction explains the chronic fatigue and pain connection frequently observed in fibromyalgia.

Patients often describe feeling trapped in a cycle where fatigue limits activity, reduced activity weakens muscles, and weakened muscles further increase pain sensitivity.

At iThrive Alive we often evaluate these patterns through metabolic assessments that look beyond surface symptoms. When mitochondrial stress and inflammatory signaling are addressed together, improvements in both fatigue and pain are often observed.

A Systems Approach to Fibromyalgia Recovery

Because fibromyalgia involves multiple biological systems, a narrow treatment strategy rarely produces long term improvement. At iThrive Alive the focus is often on restoring internal balance through a combination of lifestyle regulation, nutritional therapy, and targeted supplementation.

Sleep regulation is often one of the first priorities. Mitochondrial repair processes and nervous system recalibration largely occur during deep sleep cycles. Without consistent circadian rhythms the body struggles to repair damaged cellular components.

Smart eating patterns also play an important role. Stable blood glucose levels support consistent energy supply to mitochondria. Nutrient dense foods provide the micronutrients required for ATP production and antioxidant defense.

Targeted supplementation may further support mitochondrial function. Nutrients such as magnesium, B vitamins, and certain mitochondrial cofactors assist enzymes involved in energy metabolism.

Movement therapy is introduced gradually. Gentle physical activity can stimulate mitochondrial biogenesis which is the process through which cells produce new mitochondria. This helps rebuild cellular energy capacity over time.

The three month Alive program integrates these principles into a structured intervention that addresses the biological drivers of chronic fatigue rather than focusing only on symptom suppression.

For individuals who want a deeper evaluation of their underlying health patterns, the option to book a root cause analysis can help identify metabolic drivers that may be contributing to fibromyalgia symptoms.

Key Takeaway

Fibromyalgia is far more complex than a simple pain condition. It represents a biological intersection between nervous system hypersensitivity, mitochondrial energy disruption, and immune signaling imbalance. When cellular energy production declines and the nervous system becomes overly reactive, the body enters a cycle where fatigue, cognitive fog, and chronic pain reinforce each other. Understanding this hidden biology helps explain why fibromyalgia can feel so exhausting and unpredictable. At iThrive Alive the goal is not only to reduce symptoms but to restore the internal systems that regulate energy and neural communication. By focusing on mitochondrial health, lifestyle rhythms, and metabolic resilience, it becomes possible to move beyond symptom management and begin rebuilding the body’s capacity for sustained energy and recovery.
