You need to abstain from drinking alcohol after valve replacement surgery.
There are two types of valves used in heart valve replacement: mechanical valves and biological valves. Mechanical valves require lifelong anticoagulation, and biological valves also require anticoagulation for 3 to 6 months after replacement.
The commonly used anticoagulant drug is warfarin, and alcohol consumption triggers the instability of the drug, leading to the aggregation of warfarin in the body, which in turn may cause bleeding.
In addition, alcohol also affects the anticoagulant effect of the drug, so you should not drink alcohol after heart valve replacement. And drinking alcohol is not good for health, normal people should drink less or no alcohol, any surgery should stop drinking alcohol, so as not to affect the metabolism of drugs and physical recovery.
