What is parathyroid disorder? What does your parathyroid look like or feel like in your neck?

Overactive. An over active parathyroid gland, or hyperparathyroidism, can cause weak bones, broken bones, kidney stones, pancreatitis, stomach ulcers, abdominal pain, fatigue, depression, forgetfulness, and anxiety. A normal parathyroid gland is about the size of a grain of rice or a pea. An abnormal gland is about the size of an olive. They are nearly impossible to feel on normal examination.
High calcium. The most common disorder of the parathyroid glands is hyperparathyroidism, which is usually discovered when a blood test shows an elevated calcium level. Parathyroid cancers are very rare. A normal parathyroid gland is about a quarter inch in size, and is very deep in the neck. It can almost never be felt, even when it is abnormal.
Parathyroid. They are small glands (4) behind your thyroid about the size or a grain of rice. They are not palpable, even when overactive, unless they are cancerous. This is extremely rare.
