Hyperthyroidism is a medical condition in which the thyroid gland is overactive, leading to an excess of thyroid hormones in the body. Thyroid hormones control the body's metabolic rate, and an excess of these hormones results in a highly speeded up metabolism, with a large number of negative effects. Common symptoms of hyperthyroidism include weight loss, a simultaneous increase in appetite, anxiety, fatigue, hyperactivity, excessive sweating, heat intolerance, excessive urination, and excessive thirst. In addition, some patients experience vomiting, diarrhea, breathlessness, heart palpitations and arrhythmias, chronic itching, hair loss, and high blood pressure.
With regard to your question on malignancy - as you can see from the symptoms, hyperthyroidism is certainly not benign. Without treatment, the symptoms will get progressively worse. In severe cases, the patient can suffer what is known as a "thyroid storm", which involves fever, high blood pressure, and even heart failure. However, while growths on the thyroid gland are sometimes the cause of hyperthyroidism, these growths are usually non-cancerous. Hyperthyroidism is only rarely an indication of cancer. As for curing hyperthyroidism, there is no simple way to do it. Controlling and curing the disorder are complex and difficult, and you should discuss the available and suitable options with your doctor.
