Graves’ disease
- Autoimmune condition: An immune system disorder that causes the thyroid gland to overproduce thyroid hormone.
- Hyperthyroidism: The excessive production of thyroid hormone leads to a condition called hyperthyroidism.
- Affects multiple organs: Graves’ disease can affect various organs in the body due to the excess thyroid hormone.
- Prevalent in women and older adults: While anyone can develop Graves’ disease, it’s more common in women and individuals over 30.
- Treatment: Treatment aims to lower thyroid hormone levels and manage symptoms.
Symptoms
- Nervousness and irritability
- Tremor
- Heat sensitivity
- Weight loss
- Goiter (enlarged thyroid gland)
- Menstrual cycle changes
- Erectile dysfunction or decreased libido
- Frequent bowel movements
- Bulging eyes (thyroid eye disease or Graves’ ophthalmopathy)
- Fatigue
- Thick, discolored skin (Graves’ dermopathy)
- Fast or irregular heartbeat (palpitations)
- Sleep disturbances
Causes
- Graves’ disease: An autoimmune disorder that overstimulates the thyroid gland.
- Thyroid nodules: Noncancerous growths on the thyroid that can become overactive.
- Thyroiditis: Inflammation of the thyroid gland that can cause temporary hyperthyroidism.
- Iodine excess: Consuming too much iodine can trigger hyperthyroidism.
- Overmedication: Taking too much thyroid hormone medication can lead to hyperthyroidism.
- Other conditions: Certain tumors and medical imaging tests with contrast dye can cause hyperthyroidism.
- Sex: Females are more likely to develop hyperthyroidism than males.
- Age: The risk increases with age, especially after 60.
- Family history: A family history of hyperthyroidism increases the risk.
- Pregnancy: Pregnancy can trigger hyperthyroidism in some individuals.
Risk Factors
- Family history: A family history of thyroid conditions or autoimmune diseases can increase the risk.
- Sex: Women are more likely to develop Graves’ disease than men.
- Age: The risk is highest between the ages of 30 and 60.
- Other autoimmune conditions: Having conditions like Type 1 diabetes or rheumatoid arthritis can increase the risk.
- Smoking: Cigarette smoking can elevate the risk of Graves’ disease and thyroid eye disease.
Complications
- Pregnancy health concerns: Graves’ disease during pregnancy can increase the risk of miscarriage, early birth, fetal thyroid issues, poor fetal growth, heart failure, and preeclampsia.
- Heart conditions: Untreated Graves’ disease can lead to irregular heart rhythms and heart failure.
- Thyroid storm: A rare but life-threatening complication characterized by severe hyperthyroidism symptoms, including fever, sweating, confusion, delirium, weakness, tremors, irregular heartbeat, low blood pressure, and coma.
- Brittle bones (osteoporosis): Untreated Graves’ disease can interfere with calcium absorption and lead to weakened bones.
Prevention
- Stop smoking: Smoking can increase the risk of Graves’ ophthalmopathy.
- Eat well: A healthy diet can support overall well-being and potentially reduce inflammation.
- Exercise: Regular physical activity can improve your health and help manage symptoms.
- Take medication: Antithyroid medications can help lower thyroid hormone levels.
- Consider external antibodies: In some cases, external antibodies may be used to neutralize excess thyroid hormone production.
When to see a doctor
- Any symptoms of Graves’ disease: If you are experiencing any of the symptoms listed above, it’s important to consult with a healthcare professional for evaluation and diagnosis.
- Heart-related symptoms: If you have a fast or irregular heartbeat, or if you experience vision loss, seek immediate medical attention.
