The cause of low calcium in pancreatitis may be related to the destruction of pancreatic cells and thyroid secretion. 1. Destruction of pancreatic cells: In the course of the disease, the destruction of pancreatic cells leads to leakage of pancreatic juice, and the leaked pancreatic juice can activate lipase, and a large amount of lipase and trypsin are released into and out of the bloodstream, which can dissolve the surrounding adipose tissues, and the dissolved fats release fatty acids, which then form calcium fatty acids with calcium ions in the body, leading to a large amount of calcium ions being consumed, and then the patient will experience low calcium. The patient will have hypocalcemia. 2. Thyroid secretion: In pancreatitis, the thyroid gland is also stimulated to secrete calcitonin, which reduces the calcium content in the body, and this can also lead to low calcium. It is recommended that the patient go to the hospital in time, under the guidance of the doctor, to identify the cause of the disease, in order to avoid delaying the condition.
