For women, more than three drinks on any day or more than seven drinks a week is heavy drinking. But good evidence shows that drinking high amounts of alcohol are clearly linked to health problems. Research has demonstrated that long-term heavy drinking weakens the heart muscle, causing cardiomyopathy.
Excessive alcohol use
Heavy alcohol use can cause deficiencies in specific components of the blood, including anemia (low red blood cell levels), leukopenia (low white blood cell levels), thrombocytopenia (low platelet levels), and macrocytosis (enlarged red blood cells). Heavy alcohol use can disturb the endocrine system, disrupting the hormones that help maintain the body’s stability and health. Alcohol-related damage to nerves may also cause heart arrythmias (irregular heartbeat), postural or orthostatic hypotension (a drop in blood pressure due to a change in body position), diarrhea, and erectile dysfunction. The whole body is affected by alcohol use–not just the liver, but also the brain, gut, pancreas, lungs, cardiovascular system, immune system, and more. Excessive alcohol use can harm people who drink and those around them. More information about alcohol and cancer risk is available in the Surgeon General’s advisory.

Moderate alcohol use may not mean the same thing in research studies or among health agencies. Many people drink alcohol as a personal preference, during social activities, or as a part of cultural and religious practices. While the risk is low for moderate intake, the risk goes up as the amount you drink goes up. Drinking alcohol is a health risk regardless of the amount.

Drinking beyond thirst might be beneficial for people who need to perform tasks that require intense concentration, and those with kidney disease, kidney stones, urinary tract infections, and people with a weak sense of thirst (which may include more older people).
