If your body feels like it's in perpetual change—experiencing weight loss despite eating well, battling anxiety, noticing shifts in bowel habits, struggling with insomnia, seeing double, dealing with irritated eyes, thickened skin, hand tremors, and more—you could be dealing with Graves’ disease. This autoimmune disorder, increasingly linked to emotional stress, causes the thyroid to overproduce hormones, accelerating metabolism and affecting various organs. Let’s see what it is and what causes it:

What Is Graves’ Disease?

When the body's immune system unintentionally targets its own tissues, autoimmune illnesses result. The thyroid gland, a butterfly-shaped organ in the front of the neck, is the target of the immune system in Graves' disease. Thyroxine (T4) and triiodothyronine (T3), which control metabolism, energy levels, and other body processes, are produced by the thyroid under normal conditions.

Graves’ disease is an autoimmune disorder leading to hyperthyroidism, it is the result of the immune system producing antibodies in Graves' disease, which causes the thyroid to overproduce these hormones.  This overproduction speeds up a number of body processes, leading to symptoms like heat intolerance, irritation, weight loss, and a fast heartbeat.  Additionally, some people may develop Graves' ophthalmopathy, a disorder that causes visual impairments or bulging eyes. Different types of people can be victims of this disease but it is more common in women and people older than 30. ¹

What Causes Graves' Disease?

Graves’ disease is an autoimmune disorder where the immune system produces antibodies that mistakenly target the thyroid gland. These antibodies, specifically thyroid-stimulating immunoglobulins (TSI), bind to the thyroid-stimulating hormone (TSH) receptors on thyroid cells, mimicking the action of TSH. This stimulation causes the thyroid to overproduce hormones thyroxine (T4) and triiodothyronine (T3), leading to hyperthyroidism—a condition characterized by an accelerated metabolism affecting various organs. There are several variables are thought to have contributed to its evolution:

1. Genetic factors: The risk is raised by a family history of Graves' disease or other autoimmune conditions. A hereditary tendency is shown by the 30–35% possibility that identical twins will both be impacted. Certain immune system-related genes, including those encoding the thyroid-stimulating hormone (TSH) receptor, have been implicated. ²

2. Environmental triggers: Infections like the Epstein-Barr virus can result in triggering Graves’ disease in genetically susceptible individuals. Additionally, emotional or physical stress also triggers it 

3. Lifestyle: Stressful lifestyle can trigger it and also smoking can be a significant factor especially when it comes to developing Graves’ disease. 

4. Autoimmune mechanism: The immune system creates antibodies that resemble TSH in Graves' illness, which attach to the thyroid and cause it to overproduce hormones.  This results in symptoms like heat intolerance, weight loss, fast heartbeat, and occasionally Graves' ophthalmopathy, which is an eye condition.

What are the symptoms of Graves’ Disease?

As discussed above Grave’s disease leads to hyperthyroidism that causes the thyroid gland to produce excessive thyroid hormones. It accelerates various bodily functions leading to Graves ophthalmopathy, also known as thyroid eye disease along with many others, resulting in a range of symptoms like:

Common symptoms-

• Irregular bowel movements
• Difficulty falling asleep
• Tiredness and fatigue
• Palpitations/ irregular heartbeat
• Skin discoloration around shins
• Nervousness
• Irritability
• Tremors of hands and fingers
• Sudden weight loss
• Having thick, discolored skin mostly on the shins or tops of the feet, called Graves' dermopathy
• Erectile dysfunction
• Being sensitive to heat with an increase in sweating or warm, moist skin
• Goiter
• Changes in menstrual cycle

Eye symptoms-

• Light sensitivity
• Vision loss
• Blurred or double vision
• Bulging eyes
• A gritty feeling in the eyes
• Pressure or pain in the eyes
• Retracted eyelids
• Red or inflamed eyes

Skin-related Symptoms-

• A rare condition in which the skin thickens and turns red and may feel bumpy, like orange peel, especially on the shins or tops of the feet. This condition is referred to as pretibial myxedema or Graves dermopathy. ²

Older people may have the symptoms-

• Rapid or irregular heartbeat
• Chest pain
• Memory loss or decreased concentration
• Weakness and fatigue

How is Stress and Graves Disease Interlinked?

Stress is said to be a risk factor for the development of Grave’s disease. The researcher states that any stressful event can lead to autoimmune thyroid disease such as Basedow disease. Stress may induce Grave illness due to increased catecholamines, glucocorticoids and proinflammatory cytokines, leading to immune system hyperactivity. ³ The connection between these two is complex and multifaceted. While stress is not considered a direct cause of Graves’ disease, it can play an important role in the development of the disease. Here is what stress does:

1. Messing with the Immune system: Hormones like cortisol are cascaded due to stress. Your immune system's delicate balance can occasionally be upset by these stress hormones, which may increase the likelihood that it will attack your tissues, such as the thyroid gland in Grave's disease. Stress on the thyroid occurs by slowing your body’s metabolism. Insulin resistance and issues balancing blood sugar often occur alongside hypothyroidism. ⁴

2. A possible Trigger: For individuals who are already genetically predisposed to developing this disease, a period of significant emotional or physical stress can work as a trigger that sets Graves’ disease into motion. It is like the final push to tip something off the desk. 

3. Increases the Symptoms: Stress can increase your symptoms if you already have Graves’ disease. Those feelings of anxiety, a racing heart, shakiness, and more that often come with an overactive thyroid can become even more intense when you're under pressure.

4. A Risk Factor for More Serious Issues: In cases where hyperthyroidism from Grave's disease isn't well-controlled, severe stress can even contribute to a rare but dangerous condition called thyroid storm, where thyroid hormone levels spike dramatically.

5. Relapse: According to some research, those who have successfully managed to put Grave's disease into remission may be more susceptible to the disorder reoccurring during times of severe stress.

How does Stress Influence Thyroid Function?

Stress is something everyone experiences when challenged or analyzing threats. It is a reaction of the body that prepares it to face or escape danger. Stress-induced cytokines (e.g., IL-6, TNF-α) promote inflammation and loss of self-tolerance, enabling TRAb to stimulate excessive thyroid hormone production. However, when it becomes chronic, that’s where the problem starts, as it disrupts the body’s hormonal balance, leading to various health issues, including thyroid dysfunction. 

The body activates the hypothalamic-pituitary-adrenal (HPA) axis when facing stress and it involves:

1.  The hypothalamus releases corticotropin-releasing hormone (CRH).
2. The pituitary gland secretes adrenocorticotropic hormone (ACTH).
3. Adrenal glands produce cortisol and catecholamines (adrenaline and norepinephrine).

These hormones prepare the body for a "fight or flight" response by increasing heart rate, blood pressure, and energy availability.

By producing hormones including thyroxine (T4) and triiodothyronine (T3), the thyroid gland plays a vital role in controlling metabolism. There are various ways that stress can impact thyroid function:

• Reduced TSH Secretion: Elevated cortisol levels can suppress the release of thyroid-stimulating hormone (TSH) from the pituitary gland, leading to decreased thyroid hormone production.
• Impaired Conversion of T4 to T3: Stress can hinder the conversion of T4 to the more active T3 form, reducing the effectiveness of thyroid hormones at the cellular level.
• Increased Reverse T3 (rT3): High stress can lead to elevated levels of rT3, an inactive form of thyroid hormone, further diminishing metabolic activity.

Lifestyle Modifications for Managing Stress to Support Thyroid Health

Hormonal balance can be disrupted very easily with poor diet, stress or even lack of exercise and this leads to inflammation, potentially leading to thyroid dysfunction. Here are some of the preventative measures for lifestyle modification to support thyroid health

1. Regular workout: Frequent exercise increases metabolism and aids in hormone regulation. For the best thyroid health, try to maintain a well-rounded fitness regimen that incorporates strength training, flexibility exercises, and aerobic activities.

2. Go for regular check-ups: Regular check-ups are essential for early detection of potential thyroid issues. If you have symptoms of an overactive or underactive thyroid, your doctor can suggest a thyroid function test, a blood test that measures your hormone levels to look for problems or anomalies.

3. Eliminate environmental toxins: You can try to minimize exposure by using natural cleaning products, filtering drinking water, and being careful about environmental pollutants like chemicals and heavy metals that can interfere with thyroid function. 

4. Get enough sleep: Getting adequate sleep is a must for your betterment. Aim for 7 to 9 hours of sleep each night to regulate metabolism and hormone production. 

5. Trying to manage stress: Stress can trigger Graves syndrome. Keeping yourself busy with stress-relieving activities like yoga, meditation, deep breathing, and more can help you in the long run. 

6. Eat a balanced diet: A diet rich in nutrients is important when it comes to thyroid health. Try to include iodine-rich food in your diet like fish, seaweed, and iodized salt. Whereas, zinc found in meat aids in hormone production. 

7. Say no to processed food: Additives found in processed foods can interfere with thyroid function. Reduce consumption of artificial additives, high-fat foods, and processed sugars. Choose whole foods instead to help maintain a healthy thyroid.

Conclusion

According to research, an autoimmune condition might arise as a result of stressful life experiences that trigger the immune system. Notably, even in the absence of medical intervention, some patients have reported remission of Graves' disease symptoms after receiving stress reduction, highlighting the significance of stress management in the treatment of the illness. To promote general health and possibly lessen the effects of Graves' illness, people should prioritize stress-reduction techniques like consistent exercise, enough sleep, and mindfulness exercises.
