The vast majority of patients with pancreatitis will suffer from physical wasting. Because pancreatitis is the impaired function of the pancreas, it will directly affect the digestion and absorption of food. In the case of chronic pancreatitis patients, the effects of long-term indigestion and decreased appetite will certainly cause the body to lose weight. Patients with acute pancreatitis cannot consume protein and fat due to strict dietary requirements during the recovery period, which will cause varying degrees of malnutrition in most patients. During this period, the body will be significantly wasted due to the lack of protein and fat. Therefore, patients with pancreatitis must gradually increase nutrition in a timely and appropriate amount after recovery, and the wasting condition will gradually change after the body is fully recovered.
