Alcoholic Liver Disease (ALD): Pathophysiology

Screenshot 2025 03 27 210925 Alcoholic Liver Disease (ALD): Pathophysiology

Alcoholic liver disease (ALD) refers to liver damage caused by excessive alcohol consumption. The liver processes alcohol, but when intake exceeds the liver’s capacity to metabolize it, toxic byproducts accumulate, leading to liver injury. ALD encompasses a range of liver conditions, from fatty liver to cirrhosis, and is one of the most common causes of … Read more
