Talk to your doctor about how much alcohol you drink. Your doctor may recommend that you reduce the amount of alcohol you drink or that you stop drinking alcohol. Alcohol can:
Add calories to your daily diet and possibly cause you to gain weight.
Raise your blood pressure and levels of triglyceride fats in your blood.
Contribute to or worsen heart failure in some people, such as some people who have cardiomyopathy.
Raise your risk of other diseases such as cancer.
If you do not drink, you should not start. You should not drink if you are pregnant, are under the age of 21, taking certain medicines, or if you have certain medical conditions, including heart failure.
