Understanding Hyperthyroidism: Symptoms, Causes, and Treatments


If you’ve been feeling anxious, losing weight, or have an increased heart rate, it could be due to high thyroid levels. Hyperthyroidism is a condition caused by an overactive thyroid gland. The thyroid gland produces hormones that regulate the body’s metabolism, which means it helps control how quickly you burn calories. When the thyroid produces too many hormones, it leads to hyperthyroidism.

Common symptoms of hyperthyroidism include weight loss, increased sweating, and muscle weakness. You may also experience difficulty sleeping, tremors, or a rapid, irregular heartbeat. These symptoms may develop slowly over time or be more sudden. If you notice any of these symptoms, it’s important to see your doctor for an evaluation.

There are several different causes of hyperthyroidism, including Graves’ disease, an autoimmune disorder that attacks the thyroid gland. Additionally, a “hot” nodule, or lump in the thyroid gland that produces too much hormone, can cause hyperthyroidism. Rarely, it can be caused by certain medications or an inflammation of the thyroid gland.

Treatment will depend on the cause of the high thyroid levels. Your doctor may prescribe medications to slow down the thyroid gland’s hormone production or recommend radioactive iodine treatment to destroy some of the thyroid cells. Surgery to remove part or all of the thyroid gland may also be an option in some cases.

High thyroid levels can lead to hyperthyroidism, which can have many uncomfortable symptoms. If you suspect you may have hyperthyroidism, make an appointment to see your doctor. With proper evaluation and treatment, most people with hyperthyroidism can lead healthy, normal lives.
