How much time after appendectomy can i drink alcohol?

Yes: As i always say in these threads, how much alcohol are we talkin' about? Social use of alcohol (1-2 drinks per day, never more than 4 at one time) will not cause harm. Alcohol in higher doses suppresses immunity and may increase the chance of getting post-op infections, as well as impairing healing. You need to ask your surgeon that question, since there may be other factors in YOUR health.
