Hyperthyroidism is a condition in which the thyroid gland produces too much of the hormone thyroxine. Hyperthyroidism can significantly trigger your metabolism and cause weight loss suddenly, increasing the speed or abnormal heartbeat, sweating, and nervousness or irritability.
Several treatment options are available if you have hyperthyroidism. Doctors use anti-thyroid medications and radioactive iodine to slow the production of thyroid hormones. Sometimes, handling of hyperthyroidism include surgery to remove the thyroid gland. Although hyperthyroidism can be serious if you ignore it, many people immediately responding well so identified.
Hyperthyroidism SymptomsHyperthyroidism can mimic other health problems, which may be difficult for your doctor to know. This disease can also have signs of symptoms that vary. Symptoms of hyperthyroidism include:
• Dropped weight suddenly, even when you have an appetite and your food intake is normal or even increased• The heart beats fast (tachycardia) - commonly more than 100 beats per minute - an abnormal heartbeat (arrhythmia) or pounding of the heart (palpitation)• increased appetite• Nervousness, nausea, irritability• Vibration - usually shaking of the hands and fingers• Sweating• change in menstrual pattern• Increased sensitivity to heat• Changing patterns in the intestine, especially more frequent bowel movements• Enlarged thyroid gland (goiter), which can be characterized by swelling in the lower neck• Fatigue, muscle weakness• Difficulty sleeping
Other adults do not even have signs or symptoms or signs are subtle such as increased heart rate, intolerance to heat and tend to become tired when doing normal activities. Medical treatment called beta blockers, which are used to treat high blood pressure and other conditions, can cover many signs hyperthyroidism.
Graves' ophthalmopathySometimes unusual problems such as Graves' ophthalmopathy can result in your eyes. In this condition, your eyeballs prominent than usual due to the swelling of tissues and muscles behind your eyes. This pushes the eyeball forward. This leads to the front surface of the eye will be dry. Signs and symptoms of Graves' ophthalmopathy include:
• bulging eyeball• The eyes were swollen and red• Exit excessive tears or discomfort in one or both eyes• Sensitive to light, blurred vision or a double, inflammation, or reduced eye movementCauses & Risk FactorsCause
The thyroid is a butterfly-shaped gland at the base of the neck, just above the Adam's apple. Although it weighs less than 1 ounce, the thyroid gland has a tremendous impact on your health. Every aspect of thyroid hormone metabolism regulated.
The thyroid gland produces two main hormones, thyroxine and triiodothyronine, which affects every cell in the body. They set an average body uses fats and carbohydrates, help control body temperature, affect the average heart rate and help regulate the production of proteins. The thyroid also produces calcitonin, a hormone that helps regulate calcium levels in the blood.
How does this all work?Thyroxine and triiodothyronine are released is governed by the pituitary gland and the hypothalamus - is the area of ​​the brain that serves as a thermostat for your body system. Here's how the process works:
The hypothalamus signals the pituitary gland to make a hormone called thyroid-stimulating hormone (TSH). Pituitary gland then releases TSH - the amount based on the amount of thyroxine and triiodothyronine in your blood. If you do not have enough thyroxine or triiodothyronine in your blood, your TSH level will be above normal, and if you have too much, TSH levels will be below normal. In the end, your thyroid gland regulates the production of hormones based on the amount of TSH released.
The reason is too much thyroxineNormally, the thyroid hormone is released by the amount, but sometimes the thyroid produces too much thyroxine. This may occur for several reasons, among others:
Graves disease. These diseases are autoimmune disorders that produce antibodies by the immune system that stimulates the thyroid to produce too much thyroxine. Normally the immune system uses antibodies to help protect the body from viruses, bacteria and other foreign substances that enter the body. In this disease, antibodies attack the thyroid and sometimes incorrectly attacks the tissues behind the eyes and skin, often in the lower leg to the top. Scientists are not entirely sure what caused the disease, although several factors - including genetic predisposition - are also involved.
Hyperfunctioning thyroid nodules (toxic adenoma, toxic multinodular goiter, Plummer's disease). The form of hyperthyroidism occurs when one or more adenomas of your thyroid produces too much thyroxine. Not all adenomas produce excess thyroxine, and doctors are not sure what is causing some of them to produce too much hormone.
thyroiditis. Sometimes your thyroid gland may be swollen for unknown reasons. This swelling can cause thyroid hormones stored in the gland becomes excessive and causes deficiencies in the flow of consciousness. A rare type of thyroiditis is known as subacute thyroiditis, causing pain in the thyroid gland. Some of the other types do not cause pain and sometimes occur after pregnancy (postparum thyroiditis)
