The nurse in our department told me that his grandfather was a hypertensive patient, but his grandfather did not have the awareness of being a hypertensive patient, every time he wanted to drink some white wine at dinner, and every time he said: “I will measure my blood pressure every time I drink white wine, and my blood pressure is not high, but normal. The old man understood why after drinking, blood pressure does not rise but fall, but not good, so today we will talk about how blood pressure becomes “normal” after drinking liquor. High blood pressure is a chronic disease that requires long-term medication, there is no way to cure all high blood pressure, the need for long-term lifelong medication control, many people should also realize that high blood pressure needs to improve lifestyle, one of which is not to drink. Blood pressure drops for a short period of time after drinking a small amount of liquor, but then bounces back up after a few hours. This is definitely not a falsehood, but a process that happens 100% of the time, which is not without reason, let’s explore the hidden reasons: Alcohol makes the heart beat faster and blood vessels dilate, therefore, a small amount of alcohol will cause the blood vessels to dilate for a short time, and since blood pressure is the pressure generated by blood on the walls of the blood vessels, then the blood vessels become wider and blood pressure naturally drops temporarily, only to rise back up thereafter. Drinking alcohol will even counteract and offset the effect of antihypertensive drugs, as the majority of hypertensive patients need to take antihypertensive drugs regularly for a long time, once the effect of antihypertensive drugs disappears because of drinking, then it is particularly dangerous for hypertensive patients. A small amount of alcohol over a long period of time will cause a mild increase in blood pressure; excessive alcohol consumption will cause a significant increase in blood pressure; the increase in blood pressure will increase with the amount of alcohol consumed. The dangers of drinking alcohol for hypertension I. Alcohol can raise blood pressure. After drinking alcohol will cause sympathetic excitation, increased heart rate, enhanced myocardial contraction, increased cardiac output, and alcohol will also cause increased secretion of renin and other vasoconstrictive substances, resulting in increased blood pressure. Second, alcohol will make the blood lipids rise. Alcohol can affect liver function, thus affecting liver lipid metabolism and causing hyperlipidemia, especially hypertriglyceridemia. Long-term hyperlipidemia is easily combined with atherosclerosis, making it difficult to control blood pressure. Alcohol itself will also reduce the therapeutic effect of antihypertensive drugs. Third, it is easy to induce stroke. Long-term alcohol consumption will accelerate the emergence of atherosclerosis, easy to form cerebral thrombosis. If you drink too much alcohol, your blood pressure will rise sharply, exceeding the self-regulation function of the cerebral blood vessels, which will lead to cerebral vascular rupture and cerebral hemorrhage. Therefore, when the emergency department receives a patient in a drunken coma, if there is a previous history of hypertension, it is generally recommended to do a cranial CT to exclude the possibility of combined cerebral hemorrhage. Fourth, it is easy to develop coronary heart disease. Patients with hypertension have an excessive cardiac afterload, and sympathetic excitement and increased heart rate when drinking alcohol can increase the burden on the heart and induce myocardial infarction or even sudden death. Long-term alcohol consumption can degenerate heart muscle cells and cause heart failure. Patients with hypertension are better off not drinking alcohol, so that not only is responsible for their own lives, but also for the well-being of their families.
