Parathyroid hormone comes from four parathyroid glands in the neck, just behind the thyroid. These glands receive feedback from blood calcium levels to determine when they need to secrete the hormone. The hormone plays a role in regulating blood calcium levels, helping the body maintain adequate calcium stores in the bloodstream to protect bone health.
A thyroid nodule is a growth of thyroid tissue or a fluid-filled cyst that forms a lump in the thyroid gland. Nodules are very common. The chances of developing nodules in the thyroid gland increase as you get older. Symptoms are not common, but a large nodule may cause pain or hoarseness or get in the way of swallowing or breathing.
Polycystic ovary syndrome (PCOS) is a condition in which the ovaries produce an abnormal amount of androgens, male sex hormones that are usually present in women in small amounts. The name polycystic ovary syndrome describes the numerous small cysts (fluid-filled sacs) that form in the ovaries. However, some women with this disorder do not have cysts, while some women without the disorder do develop cysts.
The pituitary gland is a tiny organ, the size of a pea, found at the base of the brain. As the “master gland” of the body, it produces many hormones that travel throughout the body, directing certain processes or stimulating other glands to produce other hormones. The pituitary gland makes or stores many different hormones.
The thyroid gland is a small, butterfly-shaped gland located in the base of the neck just below the Adam's apple. Although relatively small, the thyroid gland plays a huge role in our body, influencing the function of many of the body’s most important organs, including the heart, brain, liver, kidneys and skin.
Osteoporosis is a condition marked by weak and brittle bones. People with osteoporosis are more likely to fracture their bones. For many adults, a fracture is the initial presentation of osteoporosis.
Testosterone is an important sex hormone in men. It is secreted by the testes and is responsible for the typical male characteristics, such as facial, pubic, and body hair as well as muscle. This hormone also helps maintain sex drive, sperm production, and bone health. The brain and pituitary gland (a small gland at the base of the brain) control the production of testosterone by the testes.
Lipids are a group of fats that include cholesterol and triglycerides.
The adrenal glands are small, triangular-shaped glands that sit on top of both kidneys. Although they are small, adrenal glands are powerful hormone factories that regulate many functions of the body such as your metabolism, immune system, blood pressure, response to stress and other essential functions.
Diabetes is a condition in which the body either does not produce enough insulin or is not able to use insulin effectively by the cells. Insulin is a natural hormone produced by your body’s pancreas gland to control the level of glucose (a type of sugar) in your blood. As a result, if you have diabetes, the glucose in the blood (often called blood sugar) becomes very high.
