Pancreatitis causes the release of a large number of active enzymes in the pancreas, including pancreatic lipase, which breaks down the body’s adipose tissue, causing necrosis of a large number of adipose tissues and combining the decomposed fatty acids with calcium to form fatty acid calcium, which causes hypocalcemia in the body due to the large amount of calcium consumption. In addition, pancreatitis can also stimulate the thyroid gland to secrete calcitonin, thus causing a decrease in blood calcium. In hypocalcemia, for example, blood calcium less than 2 mmol/L is common in severe pancreatitis, and the degree of hypocalcemia parallels the clinical severity. If the blood calcium is less than 1.5 mmol/L, it indicates a poor prognosis, so hypocalcemia is a sign of a serious condition, it is recommended to pay great attention to it, and pancreatitis must be treated early.
