Hyperthyroidism (overactive thyroid)
Hyperthyroidism, also known as an overactive thyroid, is a condition where the thyroid gland produces too much thyroid hormone. The thyroid is a small, butterfly-shaped gland located at the front of your neck, which plays a crucial role in regulating your body's metabolism. When it produces excessive thyroid hormones, it speeds up many processes in your body, leading to symptoms like rapid heartbeat, unexpected weight loss, nervousness, and sweating.
People with hyperthyroidism might notice they feel more anxious or irritable and could experience difficulty sleeping. The condition can also cause a person to have increased appetite, but despite eating more, they might still lose weight. Sometimes, it can lead to swelling at the front of the neck, known as a goitre.
The causes of hyperthyroidism vary but can include autoimmune conditions like Graves' disease, inflammation of the thyroid gland, or lumps in the thyroid. Treatment depends on the cause and severity, ranging from medications to surgical options. It's important to manage this condition with the help of a healthcare professional to avoid complications and maintain a healthy balance of thyroid hormones in the body.
