Graves' Disease
What is Graves' Disease?
Graves' disease is an autoimmune disorder that attacks the thyroid gland. Your immune system mistakenly creates antibodies that tell your thyroid to make too much hormone. This leads to hyperthyroidism, which means your thyroid is overactive.
The thyroid is a small gland in your neck that controls metabolism and energy use. When you have Graves' disease, your body produces excess amounts of thyroid hormones like T3 and T4. These hormones speed up many body functions, from heart rate to digestion.
Graves' disease affects about 1 in 200 people and is more common in women than men. It usually develops between ages 30 and 50, but anyone can get it. The condition is treatable, and early detection through blood testing helps prevent serious problems.
Symptoms
- Rapid or irregular heartbeat
- Unexplained weight loss despite normal or increased eating
- Anxiety, nervousness, or irritability
- Trembling hands or fingers
- Increased sweating and heat sensitivity
- Fatigue and muscle weakness
- Difficulty sleeping
- Bulging eyes, redness, or eye irritation
- Frequent bowel movements or diarrhea
- Enlarged thyroid gland, visible swelling in the neck
- Menstrual cycle changes in women
Some people have mild symptoms that develop slowly over time. Others experience sudden, severe symptoms. Eye problems called Graves' ophthalmopathy affect about 30% of people with this condition.

Causes and risk factors
Graves' disease happens when your immune system produces antibodies called thyroid-stimulating immunoglobulins. These antibodies bind to thyroid cells and cause them to make too much thyroid hormone. Scientists do not fully understand why the immune system attacks the thyroid, but genetics and environmental factors both play a role.
Risk factors include family history of thyroid disease, being female, age between 30 and 50, stress, pregnancy, and smoking. Other autoimmune conditions like type 1 diabetes or rheumatoid arthritis increase your risk. Viral or bacterial infections may trigger the disease in people who are genetically prone to it.
How it's diagnosed
Doctors diagnose Graves' disease with a physical exam, symptom review, and blood tests. Blood testing measures thyroid hormone levels including TSH, free T3, free T4, and total T3 and T4. In Graves' disease, TSH is usually very low while T3 and T4 are high. Testing for thyroid antibodies like TSI, thyroglobulin antibodies, and thyroid peroxidase antibodies confirms autoimmune activity.
Rite Aid's preventive health testing includes thyroid hormone panels and antibody testing to detect Graves' disease. We test for TSH, free T3, free T4, total T3, total T4, thyroid peroxidase antibodies, thyroglobulin antibodies, and TSI. Getting tested twice per year helps you catch thyroid problems early and monitor treatment progress.
Treatment options
- Anti-thyroid medications like methimazole or propylthiouracil to reduce hormone production
- Beta-blockers to manage rapid heart rate, tremors, and anxiety
- Radioactive iodine therapy to shrink the thyroid gland
- Thyroid surgery to remove part or all of the gland in severe cases
- Stress management through meditation, yoga, or counseling
- Quitting smoking to reduce eye problems and improve outcomes
- Eating anti-inflammatory foods like leafy greens, fatty fish, and berries
- Getting enough selenium and vitamin D through diet or supplements
- Avoiding excessive iodine from supplements or seaweed
- Regular monitoring of thyroid levels to adjust treatment as needed

Frequently asked questions
Graves' disease is caused by antibodies that attack the thyroid gland and make it overproduce hormones. Your immune system creates thyroid-stimulating immunoglobulins that bind to thyroid cells. Genetics, stress, infections, and other autoimmune conditions can trigger this immune response.
Graves' disease rarely goes away without treatment. About 20 to 30% of people experience remission after taking anti-thyroid medications for 12 to 18 months. However, most people need ongoing treatment with medication, radioactive iodine, or surgery to manage the condition long term.
Blood tests for Graves' disease measure TSH, free T3, free T4, total T3, and total T4 levels. Antibody tests including TSI, thyroglobulin antibodies, and thyroid peroxidase antibodies confirm autoimmune activity. In Graves' disease, TSH is very low while T3 and T4 are elevated above normal ranges.
Graves' disease specifically causes hyperthyroidism through autoimmune attack on the thyroid gland. Other thyroid conditions like Hashimoto's disease cause hypothyroidism instead. Graves' disease also causes unique symptoms like bulging eyes and skin thickening that other thyroid disorders do not typically produce.
Diet cannot cure Graves' disease, but it can support treatment and reduce symptoms. Eating anti-inflammatory foods like vegetables, fruits, and omega-3 fatty fish may help calm immune responses. Avoiding excess iodine from supplements and limiting caffeine can prevent symptom flare-ups. Always work with your doctor on dietary changes.
Graves' disease has a genetic component, and it runs in families. If you have a close relative with Graves' disease or another autoimmune thyroid condition, your risk increases. However, genetics alone do not cause the disease. Environmental triggers like stress or infection are also needed to activate it.
Untreated Graves' disease can lead to serious heart problems, including irregular heartbeat and heart failure. It can cause bone loss, eye damage, and a life-threatening condition called thyroid storm. Thyroid storm involves dangerously high fever, rapid pulse, and confusion requiring emergency care.
People with Graves' disease should get thyroid blood tests every 4 to 6 weeks when starting treatment. Once hormone levels stabilize, testing every 3 to 6 months helps monitor your condition. Regular testing ensures your treatment is working and catches any changes early.
Yes, stress can trigger Graves' disease and make symptoms worse. High stress levels may worsen immune system dysfunction and increase thyroid hormone production. Managing stress through relaxation techniques, adequate sleep, and counseling can help improve symptoms and treatment outcomes.
Not everyone with Graves' disease needs lifelong medication. Some people achieve remission after 12 to 18 months of anti-thyroid drugs and can stop treatment. Others may need radioactive iodine or surgery, which often causes hypothyroidism requiring lifelong thyroid hormone replacement. Your treatment path depends on disease severity and how you respond to therapy.
