Is the result of measuring blood pressure after drinking accurate?

The results of measuring blood pressure after drinking are generally inaccurate.

Alcohol is a stimulating drink. Drinking a lot can lead to excessive sympathetic excitation, which in turn increases the heart rate, leading to increased blood output from the heart, causing blood pressure to rise. In addition, a small amount of drinking can also dilate blood vessels, reducing blood pressure on blood vessels, resulting in blood pressure drop. If blood pressure is measured after drinking, it may make blood pressure higher or lower than the actual blood pressure, thus affecting the doctor's diagnosis of the disease. It is recommended to measure blood pressure 24 hours after drinking to ensure the accuracy of the test results.

If the blood pressure is measured on a different day and the results are lower or higher than the normal range for three times, it is an abnormal phenomenon and should be handled in a timely manner according to medical advice.
