Hypothyroidism

Hypothyroidism is the most common type of thyroid disorder. It means your thyroid gland is not active enough. This tiny gland is found in your neck. Its job is to make thyroid hormone. If the gland is underactive, it may not make enough thyroid hormone.

Rosacea

Detailed information on the most common types of rosacea, including prerosacea, vascular rosacea, inflammatory rosacea, and rhinophyma.

Hyperparathyroidism

Hyperparathyroidism occurs when 1 or more of your parathyroid glands are overactive. You have 4 of these tiny glands. Each 1 is about the size of a grain of rice. They are found in your neck, next to the thyroid gland. They keep the amount of calcium in your blood in a normal range. If these glands are overactive, they make too much parathyroid hormone (PTH). That raises the level of calcium in your blood.

Overactive Adrenal Glands

Your body has 2 adrenal glands. They are found on top of each kidney. The adrenal glands make certain types of hormones. If they make too much of (overproduce) these hormones, they are called overactive.
