Hyperthyroidism
You have been diagnosed with hyperthyroidism. This means you have a thyroid gland that makes too much thyroid hormone. This hormone helps with body growth and metabolism. If you make too much thyroid hormone, many body processes speed up. They may not work right. This can cause symptoms.
Hyperthyroidism can be caused by:
-
Graves disease. This is the most common cause. This is when the body’s immune system causes the thyroid to grow. It makes more thyroid hormone than it is needed. This happens more often in women than in men.
-
Postpartum thyroiditis. This is an inflammation of the thyroid gland. It occurs shortly after childbirth. At first, it causes hyperthyroidism. Over time it leads to an underactive thyroid gland. This is called hypothyroidism.
Symptoms of hyperthyroidism include:
-
Nervousness, anxiety, and irritability
-
Shaking (tremors) that affects the hands and fingers
-
Weight loss even though you have a normal or increased appetite
-
Low tolerance to heat
-
Sweating more than normal
-
Fast or irregular heartbeat, or bounding pulses
-
Lighter or irregular periods
-
More frequent bowel movements
-
Enlarged thyroid gland (goiter)
-
Bulging eyes, double vision, or eye irritation
-
Problems sleeping
-
Muscle weakness
-
Extreme tiredness (fatigue)
-
Swelling of the hands, ankles, or feet (older adults only)
Your healthcare provider will need to do some tests to see which form of hyperthyroidism you have. The types of treatment are different. Treatment may include taking medicines. For instance, antithyroid medicines may be prescribed. These help lower the amount of thyroid hormone made by the thyroid gland. You may need to take beta-blockers. Tips for taking medicines are given below.
Radioiodine ablation or surgery may be advised. Your provider will tell you more about these if needed.
