E05: Thyrotoxicosis [hyperthyroidism]

Thyrotoxicosis, also known as hyperthyroidism, refers to a group of conditions characterized by an overactive thyroid gland, which produces too much thyroid hormone. This excess hormone can speed up the body's metabolism, affecting your body in various ways. Common symptoms include rapid heart rate, weight loss, increased appetite, nervousness, sweating, and changes in menstrual patterns in women. You may also experience fatigue, muscle weakness, and difficulties sleeping. The presence of a thyroid nodule, inflammation of the thyroid, or certain autoimmune conditions like Graves' disease can cause these issues. Over time, untreated thyrotoxicosis can lead to serious complications such as heart problems or brittle bones. It's essential to know that these conditions can manifest differently in each person, so symptoms and disease progression may vary.
