The liver processes alcohol. Regular heavy drinking damages it in stages, often without symptoms until late.
The good news: early liver damage can improve when drinking stops.

Frequently asked questions

Fatty liver can improve within weeks to months after stopping alcohol; cirrhosis cannot be reversed but stopping prevents further damage.
