Hormones are small substances secreted by glands such as the thyroid, parathyroids, pancreas, and adrenals which are able to act on tissues elsewhere in the body to cause a specific response. Hyperaldosteronism see Conn's syndrome above. Hypercalcemia is elevation of your blood calcium level. Hyperparathyroidism refers to overactivity and growth of the parathyroid gland or glands. In the most common form, this is accompanied by hypercalcemia and may cause or worsen many problems including kidney stones, depression, ulcer disease, pancreatitis, fatigue, constipation, osteoporosis,or joint pains.
Hyperthyroidism is the overproduction of thyroid hormones.
Hypothyroidism is underproduction or ineffectiveness of thyroid hormones. Pancreas is an important gland located deep within the abdomen. It makes substances that help with digestion of food but also makes multiple hormones such as insulin, glucagon, somatostatin, and others. Pancreatectomy is an operation to remove a portion of the pancreas done for a tumor or for severe dysfunction. Parathyroidectomy is an operation to remove a parathyroid gland.
