- With regular alcohol use, the regenerative ability of liver cells may be inhibited and lead to sustained liver damage.
- Long term heavy alcohol use may lead to fat accumulation in the liver, which may progress to alcoholic hepatitis, or liver cirrhosis.
- Over time, excessive alcohol use can lead to the development of chronic diseases and other serious problems including -
- High blood pressure, heart disease, stroke, liver disease, and digestive problems.
