Cortisol, a hormone produced by the adrenal glands, is vital for the regulation of metabolism in the body. It plays a critical role in the body’s ability to cope with injury and stress. WebIn addition, people with calciphylaxis have an imbalance in the metabolism of calcium. This causes calcium to be deposited in the smallest parts of the arteries (arterioles), which eventually leads to the formation of blood clots in the arterioles. Blood clots can cause fat tissues and skin to be deprived of oxygen and nourishment. computer networking shop near me
