It can be as short as 1 week or as long as 3 months or even require abstinence from alcohol. 1. Surgical trauma: drinking alcohol will affect the healing of surgical incisions, such as gastric ulcer surgery after trauma is relatively large, alcohol will directly affect the recovery of the stomach, then at least need about three months. Some surgeries have low dietary requirements, such as eye surgery, and alcohol can usually be consumed only after one week. 2.
