Hyperthyroidism is a medical condition in which the thyroid gland produces too much thyroid hormone (called T3 and T4). It controls your metabolism, which is how your body turns food into energy. Hyperthyroidism can significantly accelerate your body's metabolism, causing sudden weight loss, a rapid or irregular heartbeat, sweating, and nervousness or irritability. It also affects your heart, muscles, bones, and cholesterol.

Hyperthyroidism is the condition in which, there is increased amount of the thyroid hormone in the body. This is generally due to over-activity of the thyroid gland in the human body. Thyroid gland is the gland that is situated at front side of the neck somewhere nearer to the voice-box. The gland play important role in the metabolism of the body. Metabolism is the process by which the body converts food particles into the consumable form and release the energy for its routine functions.

One solution to reducing iodine intake is to reduce salt intake. A list of other foods that can contain excess iodine follows:

• Seafood

• Eggs

• Dairy products

• Plants grown in iodine rich soil

• And of course sea salt or iodized salt

• Multivitamins with iodine

Causes:

It has been suggested that hyperthyroidism can be the cause, or one of the causes of celiac disease. Celiac disease is a digestive disorder that restricts your ability to properly absorb nutrients.

Hyperthyroidism also causes unhealthy weight loss, another condition that can hamper your chances to get pregnant. Also, a person with this condition will most likely suffer from weakness, irritability, and depression among a lot of other things.

It is caused by disorders wherein thyroid cells trap excess iodine and manufacture more thyroid hormone than needed. It can also be caused by disorders that can make the thyroid gland inflamed or swollen. Inflamed, swollen or damaged cells release more thyroid hormone into the bloodstream than required. Excessive presence of thyroid hormone is termed as thyrotoxicosis.

Another cause for hyperthyroidism is the presence of a thyroid adenoma or a tumor in the thyroid tissue that uncontrollably secretes increased amounts of thyroid hormone. Normal thyroid cells around the tumor stop secreting hormone due to decreased TSH levels but the tumor keeps on secreting thyroid hormone by itself. This cause does not have any association with autoimmunity.
