Is hyperthyroidism periodic?

I just had a short, month-long bout with hyperthyroidism. The cause is unknown at this time, but for now I feel back to normal. Will it come back? Is this indicative of one cause more than another?

I should add that I've looked at quite a few internet sources and haven't found an answer.

It comes back in some people and in others it don't. Your doctore can test you if you are concerned.

Hyperthyroidism is a condition caused by the effects of too much thyroid hormone on tissues of the body. Although there are several different causes of hyperthyroidism, most of the symptoms that patients experience are the same regardless of the cause (see the list of symptoms below). Because the body's metabolism is increased, patients often feel hotter than those around them and can slowly lose weight even though they may be eating more. The weight issue is confusing sometimes since some patients actually gain weight because of an increase in their appetite. Patients with hyperthyroidism usually experience fatigue at the end of the day, but have trouble sleeping. Trembling of the hands and a hard or irregular heartbeat (called palpitations) may develop. These individuals may become irritable and easily upset. When hyperthyroidism is severe, patients can suffer shortness of breath, chest pain, and muscle weakness. Usually the symptoms of hyperthyroidism are so gradual in their onset that patients don't realize the symptoms until they become more severe. This means the symptoms may continue for weeks or months before patients fully realize that they are sick. In older people, some or all of the typical symptoms of hyperthyroidism may be absent, and the patient may just lose weight or become depressed.

I would search the internet for answers to that one. www.webmd.com is a good one. I had hyperparathyroidism in 1984 and found I had a benign tumor on one of my parathyroid glands. There are four of them on the back side of your thyroid gland. My condition was pulling calcium out of my bones, etc. so I had surgery and had the tumor removed.

why don't you chek this

most cases i've heard about are chronic.

it can come back. the thyroid is regulated by your level of blood calcium, so try and stay regular with the calcium. and have plenty of iodized-salt! thatll help. good luck hun
