👉 The term "Phaeochromatium" is a medical condition that describes an abnormality in the function of the adrenal glands, specifically the parathyroid glands. It occurs when the body's production of parathyroid hormone (PTH) is too high or too low, leading to decreased levels of calcium in the blood and bone density. This imbalance can cause osteoporosis, which is a weakened bone that increases the risk of fractures and falls.
