If you experience unexplained weight loss, a rapid heartbeat, unusual sweating, swelling at the base of your neck or other symptoms associated with hyperthyroidism, see your doctor.

How is hyperthyroidism diagnosed?
The doctor can make a diagnosis from the medical history, physical examination, and blood tests to measure blood thyroid hormone levels. The doctor may also order a thyroid scan or ultrasonography to get pictures of the thyroid gland. The doctor may also suggest seeing a thyroid specialist.
How is hyperthyroidism treated?
The doctor will treat hyperthyroidism by lower thyroid hormone levels in your body. This hormone levels can be lowered with medicines, radiation therapy, or surgery.
- Medicines may be needed for a few months, a few years or more. Ones that prevent thyroid hormone production include propylthiouracil (PTU) and methimazole. They can be used as the main therapy or to prepare for other treatments.
- Radioactive iodine is used to destroy the thyroid. This therapy is best for people older than 21 and younger people who cannot control their disease with medicines.
- Surgery is for people with large thyroid glands that block or interfere with other structures in the neck. People who do not want to use radioactive iodine may have surgery. Pregnant women may also need surgery.
Lifestyle changes & home remedies
What are some lifestyle changes or home remedies that can help me manage hyperthyroidism?
The following lifestyles and home remedies might help you cope with hyperthyroidism:
- Protect your eyes if you have eye complications of Grave’s disease. Use sunglasses and artificial tears, and wear eye protection at night
- Remember that radioactive iodine shouldnot be used during pregnancy. It may cause an underactive thyroid condition in the baby.
- Realize that successful treatment means that you need lifelong care. The doctor must check you for onset of an underactive thyroid gland (hypothyroidism) after treatment and for possible recurrence of hyperthyroidism.
- Call your doctor if you have palpitations, serious weight loss, diarrhea, or tremors.
- Call your doctor if you have restlessness, anxiety, or mood swings.
- Donot do physical exercise until your illness is controlled
- Donot smoke. Smoking may worsen eye problems
- Remember that complications of surgery may include paralysis of vocal cords, underactive thyroid (hypothyroidism) and calcium problems. Calcium problems can result if parathyroid glands are accidentally removed
- Remember that hyperthyroidism may recur after surgery in 10% to 15% of people.
If you have any questions, please consult with your doctor to better understand the best solution for you.
