The causes of hypotension mainly include constitutional hypotension, postural hypotension and secondary hypotension, which need to be treated according to different causes.
1. Constitutional hypotension: It is generally believed to be related to heredity and thinness, and the main treatment is to actively participate in physical exercise, improve physical fitness, increase nutrition, drink more water, eat more soups, and consume slightly more salt than normal people every day.
2. Postural hypotension: when the patient goes from lying to sitting or upright position, there is a sudden drop in blood pressure (systolic blood pressure more than 20mmHg, and/or diastolic blood pressure more than 10mmHg), and dizziness, lightheadedness, blurred vision, fatigue, nausea, and other symptoms may appear. At this time, attention should be paid to change the body position for the prone position, such as no uncomfortable symptoms can be without treatment, the emergence of obvious symptoms can be used when necessary, such as dopamine and other drugs to elevate blood pressure. If there are obvious symptoms, drugs such as dopamine can be used to raise the blood pressure.
3. secondary hypotension: caused by some antihypertensive drugs or antidepressant taking improper or too much, this time need to adjust the dose in time, if necessary, stop observing.
Therefore, when low blood pressure occurs, it is necessary to go to the hospital in time to avoid delaying the condition.
