Most of the hernia surgeries do not lead to wasting, and the main reasons for wasting are related to the reduction of dietary intake and the influence of intestinal function. 1. Decreased dietary intake: After hernia surgery, the early stage of the disease is due to the deviation of the physical condition, the food intake is low, which will lead to the consumption of fat and cause wasting. 2. Impact on intestinal function: After surgery, some people may suffer from intestinal dysfunction, which affects digestion and absorption and further leads to wasting. During the recovery period after hernia surgery, we should pay attention to avoid too strenuous exercise to avoid the increase of abdominal pressure. If you continue to lose weight after the surgery, and with the decline of physical condition, you need to be admitted to the hospital in time to observe and further diagnose the specific patient’s condition, and carry out standardized treatment under the guidance of the clinician, so as to avoid any delay in the condition.
