Introduction
Alcohol is a common part of social gatherings and celebrations, but excessive or long-term consumption can have serious consequences on your health. While moderate drinking may not always be harmful, high alcohol intake can lead to physical, mental, and social problems. Understanding these risks can help you make informed choices about alcohol consumption.

2. Heart Problems
Heavy drinking increases the risk of:
- High blood pressure
- Irregular heartbeat (arrhythmia)
- Cardiomyopathy (weakening of heart muscles)
- Increased risk of stroke
