When your body’s engine revs too high for too long, it starts to wear down—and that’s kind of what happens in Graves’ disease, a condition that causes hyperthyroidism. While not everyone has heard of it, Graves’ disease is one of the most common autoimmune disorders, and it’s the leading cause of hyperthyroidism in the United States.
In this blog, we’ll dive deep into Graves’ disease, what causes it, what symptoms to look out for, and the most effective treatment options available today. Whether you’re recently diagnosed, know someone dealing with this condition, or just curious about thyroid health, this guide is for you.
What is Graves’ Disease?
Graves’ disease is an autoimmune disorder that affects the thyroid gland, a small, butterfly-shaped gland located at the front of your neck. In this disease, the immune system mistakenly attacks the thyroid, causing it to become overactive. This results in hyperthyroidism, a condition where your thyroid produces more hormones than your body needs.
Thyroid hormones are crucial—they regulate your metabolism, heart rate, body temperature, and more. When these hormones are in overdrive, your body starts speeding up all its functions, which can wreak havoc on your health.
- Graves’ disease affects about 1 in 200 people in the U.S.
- It’s 7 to 8 times more common in women than in men.
- The typical age of onset is between 30 and 50 years, but it can occur at any age.
What Causes Graves’ Disease?
Graves’ disease is triggered by a malfunction in the immune system. Normally, the immune system protects the body from viruses and bacteria. But in autoimmune diseases like Graves’, it mistakenly targets your tissues—in this case, the thyroid gland.
The immune system produces an antibody called thyroid-stimulating immunoglobulin (TSI). This antibody binds to the thyroid-stimulating hormone (TSH) receptor on the thyroid gland, tricking it into overproducing thyroid hormones.
There’s no single cause, but several risk factors increase your chances of developing Graves’ disease:
- Genetics: A family history significantly raises your risk. Studies show that about 30% of patients with a first-degree relative who has Graves’ disease are more likely to develop the condition themselves, indicating a strong genetic component.
- Gender: Women are more likely to develop it.
- Other autoimmune diseases: Conditions like type 1 diabetes, rheumatoid arthritis, or lupus may be linked.
- Stress: Severe emotional stress or trauma can sometimes trigger it.
- Infections: Certain infections may play a role in immune system disruption.
- Smoking: Smokers are at higher risk, particularly of eye-related complications (Graves’ ophthalmopathy).
Risk Factors:
Symptoms of Graves’ Disease
Symptoms can be wide-ranging and sometimes subtle at first. Because thyroid hormones affect almost every part of the body, the symptoms of hyperthyroidism can appear in many forms. Here are the most common ones:
Common Symptoms:
- Weight loss despite normal or increased appetite
- Rapid or irregular heartbeat (palpitations); Around 70–80% of patients experience a rapid or irregular heartbeat (tachycardia), and 50–60% report heightened anxiety, irritability, or nervousness.
- Tremors, especially in the hands or fingers
- Increased sweating
- Heat sensitivity
- Goitre (enlarged thyroid gland)
- Fatigue or muscle weakness. affecting up to 80% of individuals, particularly in the upper arms and thighs.
- Menstrual irregularities
- Frequent bowel movements
- Sleep disturbances
- Thinning skin and brittle hair
Graves’ Ophthalmopathy
Around 30% of people with Graves’ disease experience eye problems, known as Graves’ ophthalmopathy. This happens when the immune system mistakenly attacks the muscles and tissues around the eyes.
Symptoms include:
- Bulging eyes (exophthalmos)
- Dry, red, or irritated eyes
- Double vision
- Light sensitivity
- Eye pain or pressure
In rare cases, this condition can lead to vision loss if left untreated.
Diagnosing Graves’ Disease
If you or your doctor suspect Graves’ disease, several tests can help confirm the diagnosis:
Blood Tests:
- TSH (Thyroid Stimulating Hormone): Low in Graves’ disease
- T3 and T4 (thyroid hormones): Elevated levels
- TSI (thyroid-stimulating immunoglobulins): Present in Graves’ disease
- Anti-thyroid peroxidase antibodies: May be elevated in autoimmune thyroid diseases
Imaging Tests:
- Radioactive iodine uptake (RAIU): Measures how much iodine the thyroid absorbs. High uptake suggests Graves’ disease.
- Thyroid scan: Gives a visual map of thyroid activity.
Treatment Options for Graves’ Disease
The good news? Graves’ disease is very treatable. Depending on the severity, age, and individual needs, treatment can vary. The goal is to reduce thyroid hormone levels and manage symptoms. With the right treatment, more than 95% of individuals with Graves’ disease can effectively manage their condition and avoid long-term complications.
- Antithyroid Medications
These drugs reduce the amount of hormones produced by the thyroid.
- Methimazole (Tapazole) – The most commonly prescribed.
- Propylthiouracil (PTU) – Often used during pregnancy or in specific cases.
Duration: Typically taken for 12–18 months.
Pros:
- Non-invasive
- No permanent thyroid damage
Cons:
- Potential side effects (rash, liver issues, decreased white blood cell count)
- Not always a permanent fix—relapse rates are around 50–70%
- Radioactive Iodine Therapy (RAI)
This treatment involves taking a radioactive iodine pill. The iodine is absorbed by the thyroid and gradually destroys the overactive thyroid cells.
Effective in up to 90% of cases after a single dose.
Pros:
- Non-surgical
- Permanent solution
Cons:
- Often results in hypothyroidism, requiring lifelong thyroid hormone replacement
- Not recommended during pregnancy or breastfeeding
- Surgery (Thyroidectomy)
A partial or total removal of the thyroid gland may be necessary in severe or complicated cases, or when other treatments aren’t suitable.
Pros:
- Immediate and permanent solution
- Avoids radioactive exposure
Cons:
- Involves general anesthesia
- Risk of damage to nearby structures like vocal cords or parathyroid glands
- Requires lifelong hormone replacement
- Beta Blockers
While not treating the underlying cause, these help manage symptoms like rapid heartbeat, tremors, and anxiety. Common options include propranolol and atenolol. For instance, beta blockers reduce resting heart rate by an average of 25–30% in hyperthyroid patients within days of starting treatment.
Treatment for Graves’ Eye Disease
Graves’ ophthalmopathy may need separate treatment:
- Artificial tears for dryness
- Steroids to reduce inflammation
- Orbital decompression surgery for severe cases
- Radiation therapy to reduce swelling
There’s also a new FDA-approved drug specifically for thyroid eye disease: Teprotumumab (Tepezza).
Lifestyle Tips for Managing Graves’ Disease
In addition to medical treatment, lifestyle plays a big role in managing symptoms and improving quality of life.
Diet & Nutrition:
- Eat a balanced, anti-inflammatory diet rich in vegetables, fruits, lean protein, and whole grains.
- Avoid excessive iodine (like from seaweed or supplements) unless directed otherwise.
- Watch for foods that may trigger immune responses (gluten, dairy, etc.) in sensitive individuals.
Stress Reduction:
Stress is a known trigger. Try:
- Meditation or mindfulness
- Gentle exercise (like yoga or walking)
- Adequate sleep (7–9 hours per night)
Quit Smoking:
Smoking worsens eye problems in Graves’ disease and increases the risk of recurrence.
Long-Term Outlook
With the right treatment and follow-up, most people with Graves’ disease live full, healthy lives.
Key Stats:
- Around 30–40% of patients relapse after stopping antithyroid medications.
- Lifelong hormone replacement is required for nearly all patients who undergo RAI or surgery.
- Early diagnosis and treatment improve outcomes and reduce complications.
Patient´s Story: Graves’ Disease and Pregnancy
A Reddit User shares her experience of tackling Graves’ Disease while being pregnant. Last year, during her first trimester of pregnancy, she experienced persistent nausea and an unusually high resting heart rate in the 90s. Despite a known family history of thyroid disease, her thyroid levels weren’t tested, as her symptoms were attributed to typical pregnancy hormone fluctuations. Unbeknownst to her, she had undiagnosed Graves’ disease.
Fortunately, her hyperthyroidism self-resolved during pregnancy, and she gave birth to a healthy baby boy. However, her symptoms returned severely eight months postpartum, leading to a formal diagnosis of Graves’ disease. While it was a delayed diagnosis, she remains grateful for her thriving child and now has clarity on her condition.
Patient´s Story: Success With Surgery
Reddit User The Duke Macklin was diagnosed with Graves’ disease in his early years. After spending about three years on methimazole, he eventually underwent thyroid removal surgery. Now, 1.5 years post-surgery, he is feeling better than ever and is in the best shape of his life. Though it took time to come to terms with the lifelong need for medication, he believes there’s hope for everyone, acknowledging that each person’s journey is unique.
