Hyperthyroidism refers to an overreactive thyroid gland. We look at the symptoms of hyperthyroidism, and how it can be treated.
Hyperthyroidism is over activity of the thyroid which occurs when the gland makes too much thyroid hormone for the body's needs. This speeds up your metabolic rate up and therefore every organ in the body works faster. You may have any or all of the following symptoms:
- Fidgety, irritable and on edge
- Increased appetite but loss of weight
- Tremor, feeling hot and sweaty
- Heart racing, palpitations
- Irregular periods
- Some people simply feel tired.
One in twenty patients may notice changes to their eyes, usually with puffiness of the eyelids, a gritty sensation in the front of the eyes and sometimes a 'staring' appearance. Rarely the changes can be more severe, making the eyes very prominent and causing double vision. If this happens you will need to see an eye specialist. It is known that smokers are more likely to get eye changes than those who do not smoke.
Carbimazole (also called Neomercazole)
This tablet reduces the amount of thyroid hormone being made by the thyroid gland and takes two to three weeks to become fully effective. Usually a higher dose is used at the start (20 to 40 mg once daily) and then the dose is progressively cut down to a maintenance dose (5 to 10 mg daily).
Very occasionally a higher dose is started and maintained (60 mg daily). This then has to be supplemented by a thyroid hormone tablet (Thyroxine) to maintain normal thyroid hormone levels in the blood stream. This is called the 'block and replace' regimen.
Most tablets have side effects. Although, in Carbimazole these may be severe enough to lead to the tablet being stopped. These side effects include:
- Skin rashes
- Aches and pains in the joints
- Bone marrow suppression - this is a very rare (less than 1 in 20,000 cases)
- Weight gain - this is often the side effect that patients most worry about, but it is not really a side effect at all. If you do gain weight on treatment it probably means that the thyroid gland is getting better and that the metabolic rate is slowing down to normal.
