After liver damage, you should not do heavy work before the liver function is normalized, but you can do heavy work after the liver damage is recovered. The liver is a very important organ in the human body, with functions such as detoxification and elimination, metabolism and energy storage. There are several reasons why it is not recommended to do heavy labor after liver damage: 1. When doing heavy physical labor, it needs to increase the amount of blood circulating in the liver, and the metabolic function of the liver is burdened, once the blood supply to the liver is insufficient, causing ischemia of the liver, it will aggravate the damage to the liver. 2. Excessive physical labor will make the body too tired, consume a lot of nutrients and oxygen, increase the burden on the liver, and easily deteriorate the patient’s condition. 3. When doing heavy physical labor, holding breath and exerting oneself will increase the intra-abdominal pressure, aggravate esophageal varices and fundal varices, and even lead to rupture of blood vessels, causing hemorrhage. After complete recovery from liver damage, heavy work can be done as appropriate according to medical advice. Patients with liver damage are advised to take appropriate exercise according to their own conditions, eat a light diet and go to the hospital regularly for follow-up.
