What Happens to Liver After 30 Days Without Alcohol? Science Explained

What Happens to Your Liver If You Quit Alcohol for 30 Days | Science Explained

In this Science Explained video, we examine what happens to your liver when you quit alcohol for 30 days and how alcohol cessation affects liver function, inflammation, and recovery. This video explains the science behind alcohol metabolism and why reducing alcohol intake can lead to measurable liver improvements.

Alcohol is processed in the liver and produces toxic byproducts that contribute to inflammation, oxidative stress, fat accumulation, and long-term liver damage. When alcohol intake stops, these processes begin to slow, allowing the liver to repair and restore normal metabolic function. We explain what changes occur during the first days without alcohol and how liver health can improve within weeks.

Discover:
• How alcohol is metabolized in the liver
• What happens in the first 72 hours without alcohol
• How inflammation and oxidative stress decrease
• Why liver fat and enzyme levels can improve
• What science says about liver recovery after 30 days.
