Whether drinking beer, or drinking liquor, it is easy to cause high blood pressure. Because both beer and liquor contain ethanol, ethanol will be quickly divided in the body, explaining the release of acetaldehyde, acetaldehyde will make the capillaries appear permeable open, there will be blood pressure first drop and then rise, in addition, drinking beer or liquor will also appear sympathetic nerve overexcitation, resulting in increased myocardial contraction, increased myocardial oxygen consumption, myocardial contraction force, which will further increase blood pressure. Heavy alcohol consumption also results in the release of acetaldehyde into the bloodstream, causing contraction of the capillary sphincter, which can further increase blood pressure. Heavy alcohol consumption also causes imbalance in the function of the endocrine system, which can lead to secondary activation of the renin-angiotensin-aldosterone system in the body, and can predispose to hypertension.
