The possible harms of drinking in patients with fatty liver include: aggravating liver damage, increasing the risk of cancer, damaging the gastric mucosa, increasing the risk of accidental injury, and so on. 1. Exacerbate liver damage: long-term drinking people are prone to liver steatosis, forming alcoholic fatty liver. If the patient already has fatty liver and continues to drink alcohol, it will accelerate liver steatosis, and then form alcoholic cirrhosis, which will seriously damage the liver function. 2. Increase the risk of cancer: The World Health Organization has listed alcohol as a class of carcinogens, and there is clear evidence that alcohol is closely related to the occurrence of certain cancers, such as gastric cancer, esophageal cancer, liver cancer and so on. In particular, people who already have fatty liver continue to drink alcohol. The incidence of liver cancer will be greatly increased. 3. Damage to gastric mucosa: Alcohol enters the stomach and damages the gastric mucosa, which can induce acute gastritis, gastric ulcer and other gastric mucosal lesions. 4. Increase the risk of accidental injury: after drinking alcohol, many people are in a state of unconsciousness and are prone to accidental injuries, such as car accidents, falls, and crashes. Alcohol consumption is harmful to health in many ways, especially for patients who already suffer from underlying diseases such as hypertension, atherosclerosis and fatty liver. It is recommended to maintain a healthy lifestyle and consume as little or no alcohol as possible.
