After taking antihypertensive drugs for several years, the sudden decrease of blood pressure may be due to overdose, myocardial ischemia, postural hypotension and other reasons.
1. Overdose: some hypertensive patients will occasionally forget to take antihypertensive drugs, resulting in the situation of multi-service or oral antihypertensive drug dosage is relatively large, and is not suitable for the current blood pressure, will be in a few years of antihypertensive medication, the performance of a sudden decrease in blood pressure, you can record the time of their own medication, the dosage of antihypertensive drugs overdose reduction of the oral dosage of antihypertensive drugs, the need for replacement of antihypertensive medication.
2. Myocardial ischemia: patients with myocardial ischemia, myocardial blood supply is insufficient for a long time, myocardial tissue nutritional disorders and atrophy, serious large myocardial infarction, resulting in insufficient coronary artery perfusion, which leads to a sudden drop in blood pressure, will also show that after several years of antihypertensive medication, the blood pressure suddenly decreased.
3. Postural hypotension: some hypertensive patients with decreased function of nerve pressure receptors will have low blood pressure due to changes in body position.
After taking antihypertensive drugs for several years, the blood pressure is lowered more seriously, accompanied by other discomforts to consult a doctor in time, and the drugs need to be taken according to the doctor’s prescription.
