Hyperthyroidism is an imbalance of metabolism caused by overproduction of thyroid hormone.
|
|
|
When you have hypothyroidism, your thyroid gland doesn’t produce enough hormone. With hyperthyroidism, the thyroid gland produces too much hormone. A goiter is the enlargement of the thyroid gland.
|
|
Hyperthyroidism is the condition that reflects excessive concentrations of thyroid hormones, due to any cause. The resulting hypermetabolic state causes increased heat production and accelerates many of the bodies ' processes.
|
|
|
Hyperthyroidism is the overproduction of thyroid hormones by an overactive thyroid gland. Located in the front of the neck, the thyroid gland produces the hormones thyroxine (T 4 ) and triiodothyro-nine (T 3 ) that regulate the body ' s metabolic rate by helping to form protein ribonucleic acid (RNA) and increasing oxygen absorption in every cell.

Hyperthyroidism is the overproduction of thyroid hormones by an overactive thyroid. The term hyperthyroidism covers any disease which results in overabundance of thyroid hormone.

Pernicious anemia is caused by a lack of intrinsic factor, a substance needed to absorb vitamin B-12 from the gastrointestinal tract. Vitamin B-12 is necessary for the formation of red blood cells. Anemia is a condition where red blood cells are not providing adequate oxygen to body tissues. There are many types and causes of anemia. (See the general article - anemia ) Pernicious anemia is a type of megaloblastic anemia .

|
|
Pernicious anemia is a disease in which the red blood cells are abnormally formed, due to an inability to absorb vitamin B 12 . True pernicious anemia refers specifically to a disorder of atrophied parietal cells leading to absent intrinsic factor, resulting in an inability to absorb B 12 .

Skin cancer is the uncontrolled growth of skin cells. If left unchecked, these cancer cells can spread from the skin into other tissues and organs. There are different types of skin cancer. Basal cell carcinoma is the most common. Melanoma is less common, but more dangerous.
|
|
|
Skin cancer is a malignant growth of the external surface or epithelial layer of the skin. Skin cancer is the growth of abnormal cells capable of invading and destroying other associated skin cells.
