You can’t tell if your blood pressure is dropping by how long you quit drinking. However, there is a tendency for blood pressure to drop in most patients after quitting drinking. Alcohol consumption is a risk factor for the development of hypertension, and blood pressure levels are higher in small or moderate drinkers than in non-drinkers. The mechanism by which alcohol (ethanol) causes an increase in blood pressure is still unclear, and may be related to the following mechanisms, including: activation of the renin-angiotensin-aldosterone system, affecting the function of the vascular endothelium, and inhibiting vasodilatory substances and other effects that elevate blood pressure. If hypertensive patients are diagnosed with chronic alcoholism, it will cause serious damage to organs such as the heart, brain and liver. Lowering blood pressure should be achieved by improving lifestyle habits, including dietary adjustments, reasonable exercise, etc., and should be accompanied by appropriate antihypertensive medication, etc., under the guidance of a physician for long-term use. Blood pressure should be lowered through a comprehensive approach rather than just by quitting drinking.
