Hyperthyroidism - Symptoms, Causes & Treatment
Hyperthyroidism is a condition where the thyroid gland produces too much thyroid hormone, causing the body's metabolism to speed up significantly.
Overview
Hyperthyroidism affects about 1-2% of the population and is more common in women. Graves' disease is the most common cause, accounting for about 70% of cases.
If untreated, hyperthyroidism can lead to serious complications including heart problems, bone loss, and thyroid storm — a life-threatening condition. Early diagnosis and treatment are essential.
Symptoms of Hyperthyroidism
- PalpitationsPrimary
Palpitations are feelings of having a fast-beating, fluttering, or pounding heart. They can be felt in the chest, throat, or neck.
- TremorsPrimary
Tremors are involuntary, rhythmic shaking movements of one or more parts of the body, most commonly the hands.
- Fatigue
Fatigue is a feeling of persistent tiredness or exhaustion that does not improve with rest. It can be physical, mental, or both, and may indicate an underlying health condition.
- Diarrhea
Diarrhea is characterized by loose, watery stools occurring more frequently than usual. It can be acute (lasting 1-2 days) or chronic (lasting more than 4 weeks).
- Insomnia
Insomnia is a sleep disorder characterized by difficulty falling asleep, staying asleep, or getting quality sleep, despite having adequate opportunity for sleep.
- Mood Swings
Mood swings are rapid, unexplained changes in emotional state, from feeling happy and energetic to feeling sad, angry, or irritable.
- Hair Loss
Hair loss (alopecia) is the thinning or loss of hair from the scalp or other parts of the body. It can be temporary or permanent, gradual or sudden.

Hyperthyroidism FAQs
Common questions about hyperthyroidism.
Graves' disease is an autoimmune disorder and the most common cause of hyperthyroidism. The immune system produces antibodies that stimulate the thyroid to produce excess hormones. It can also cause eye problems (Graves' ophthalmopathy).
If left untreated, hyperthyroidism can lead to heart problems (atrial fibrillation, heart failure), osteoporosis, and thyroid storm. However, with proper treatment, most people can manage the condition effectively.
