chronic endocrine disorder where the adrenal glands do not produce sufficient steroid hormones (glucocorticoids and often mineralocorticoids).[1] Lifelong‚ continuous treatment with steroid replacement therapy is required‚ with regular follow-up treatment and monitoring for other health problems.[2] It is generally diagnosed via blood tests and medical imaging.[2] Treatment involves replacing the absent hormones (oral hydrocortisone and fludrocortisone).

neck behind the thyroid. There are 4 parathyroid glands in the human body. Parathyroid glands control the calcium in our bodies – how much calcium is in our bones‚ and how much calcium is in our blood. Parathyroid glands secrete or make a hormone‚ called parathyroid hormone or PTH. The parathyroid glands measure the amount of calcium in the blood every minute of every day and if the calcium levels go down a little bit‚ the parathyroid glands recognize it and make parathyroid hormone (PTH) which goes
