What are Graves Disease and Hyperthyroidism?
Graves disease is an autoimmune disorder where the immune system attacks the thyroid gland and stimulates it to produce excessive amounts of thyroid hormones. This condition leads to hyperthyroidism (overactive thyroid), where there are too many thyroid hormones in the body. Graves’ disease is more common in women between the ages of 30 and 50, but it can also affect men. Due to the thyroid’s excessive hormone production, hyperthyroidism causes an acceleration of metabolism, which manifests in various symptoms throughout the body.
What are the Causes of Graves' Disease and Hyperthyroidism?
Genetic and environmental factors can play a role in the development of Graves’ disease:
- Autoimmune Reaction: In Graves’ disease, the immune system attacks the thyroid gland, causing it to produce too many thyroid hormones.
- Genetic Predisposition / Family History: Individuals with family members who have Graves’ disease have a higher risk of developing the condition.
- Environmental Factors: Stress, infections, smoking, and exposure to environmental pollutants can contribute to the development of Graves’ disease.
- Excessive Iodine Intake: Too much iodine can lead to an overactive thyroid (hyperthyroidism).
What are the Symptoms of Graves' Disease and Hyperthyroidism?
Graves’ disease and hyperthyroidism can manifest through various symptoms. The most common symptoms include:
- Excessive sweating and hot flashes: Hyperthyroidism can lead to an increase in body temperature and sweating problems.
- Rapid heartbeat (tachycardia) / Fast heart rate: High thyroid hormone levels speed up the heart rate, leading to a faster heartbeat.
- Nervousness and anxiety: The acceleration of metabolism can lead to nervousness, restlessness, and feelings of anxiety.
- Weight loss: Despite normal or increased food intake, weight loss may occur due to the increased metabolism. However, this is not the case for every patient and depends on the severity of the condition.
- Fatigue and muscle weakness: Because the body is working excessively, muscle weakness and tiredness can occur.
- Eye problems: Graves’ disease can lead to symptoms such as swelling, pain, and double vision in the eyes (endocrine orbitopathy or Graves’ ophthalmopathy).
- Tremors in the hands / Shaky hands: Due to hyperthyroidism, a fine tremor of the hands may occur.
- Skin involvement: Hardening and changes in skin color may occur on the shins (upper part of the lower legs) and feet (pretibial myxedema).
How are Graves' Disease and Hyperthyroidism Diagnosed?
Various tests are conducted to diagnose Graves’ disease and hyperthyroidism:
- Blood Tests: TSH (Thyroid Stimulating Hormone), T3, and T4 levels are measured to evaluate thyroid functions. Hyperthyroidism is typically diagnosed by low TSH levels and high free T3 and free T4 levels.
- TSH Receptor Antibodies (TRAb) Test: This test detects antibodies against the thyroid gland, which are typically elevated in Graves’ disease and help in diagnosis.
- Thyroid Ultrasound: Used to assess the structural characteristics of the thyroid gland.
- Thyroid Scintigraphy: Used to perform differential diagnoses in the identification of Graves’ disease.
How are Graves' Disease and Hyperthyroidism Treated?
Various options are available for the treatment of Graves’ disease and hyperthyroidism (overactive thyroid). Dr. Burcu Meryem Atak Sançmış supports patients with individualized treatment plans to help them lead healthy lives. Treatment methods may include the following:
- Medication Therapy:
- Antithyroid Medications: Drugs that inhibit the production of thyroid hormones help to normalize the patient’s thyroid hormone levels.
- Beta-Blockers: Can be used to regulate heart rate and relieve symptoms.
- Radioiodine Therapy: Radioactive iodine destroys overactive thyroid cells, thus treating hyperthyroidism.
- Surgery: If medications and radioiodine therapy are not sufficiently effective, part or all of the thyroid gland can be surgically removed (thyroidectomy).
- Supportive Therapy: This treatment may include eye care (for endocrine orbitopathy/Graves’ ophthalmopathy) and psychological support to improve patients’ quality of life.
Complications of Graves' Disease and Hyperthyroidism
If left untreated, Graves’ disease and hyperthyroidism (overactive thyroid) can lead to the following complications:
- Cardiovascular Diseases / Heart Problems: An excess of thyroid hormones can cause heart problems (heart failure, heart rhythm disorders / arrhythmias).
- Osteoporosis / Brittle Bones: Hyperthyroidism can decrease bone density, leading to weakened bones.
- Kidney Problems / Kidney Dysfunction: Hyperthyroidism can cause damage to the kidneys.
- Endocrine Orbitopathy (Graves’ Ophthalmopathy) / Graves’ Eye Disease: Swelling, redness, and vision problems can occur in the eyes.
- Thyroid Storm: A sudden and severe increase in thyroid hormones in the body is a serious medical emergency.
Frequently Asked Questions
Can a person with Graves' disease live a normal life?
Can a person with Graves’ disease live a normal life?
Yes, after successful treatment for Graves’ disease, most patients can lead a normal life. However, as it is an autoimmune condition, the disease can recur even after remission, which is why regular follow-up examinations are important.
What happens if Graves' disease is not treated?
Untreated Graves’ disease can lead to serious health problems. However, these risks can be minimized with appropriate treatment.
How long does the treatment for Graves' disease last?
The duration of treatment varies individually but should be at least 18-24 months with continuous intake of antithyroid medications. Control of Graves’ disease can take several months, with a euthyroid state (normal thyroid function levels) ideally achieved within the first 6 months with the appropriate treatment dose.
Is taking medication alone sufficient to treat hyperthyroidism?
In most cases, medication therapy can be sufficient to control hyperthyroidism (overactive thyroid). However, some patients may require additional treatment methods.
When is Graves disease diagnosed?
Diagnosis is usually made after the onset of symptoms through appropriate tests. However, it is also possible for the diagnosis to be made during routine check-ups in asymptomatic patients. Therefore, early diagnosis is important.
Are there specific dietary recommendations for people with Graves disease?
While a low-iodine diet was previously recommended, current study data shows that a restrictive iodine diet is no longer generally recommended.
Is Graves' disease serious during pregnancy?
Yes. Medication treatment is different during pregnancy and requires close monitoring with frequent check-ups through proper management. Women wishing to have children should seek pre-conception counseling regarding various treatment options.
What is transient gestational hyperthyroidism?
Transient gestational hyperthyroidism is characterized by an increase in β-hCG levels and simultaneously in thyroid hormones due to similar mechanisms as pregnancy hormones. It usually normalizes between the 14th and 18th week of pregnancy if symptoms and abnormal thyroid function values are present.
