Alcohol and High Blood Pressure
Alcohol is a well-known independent risk factor for cardiovascular diseases. Though Low amount of alcohol is beneficial for the heart and blood vessels, drinking large amount of alcohol can result in raised blood pressure. Excessive alcohol increases the risk of many other cardiovascular events and not just hypertension.
Mechanisms by which alcohol causes hypertension have not been fully elucidated and is likely to be due to multiple mechanisms like increased activity of sympathetic nervous system, increase cortisol levels, damage to the baroreceptors (blood pressure sensors) and numerous others.
