Blood pressure is not necessarily a precursor of any disease, which may be related to the time of taking antihypertensive drugs, the change of seasons, etc. However, if it is substantially high and low, it is necessary to consider pheochromocytoma.
1. Time of taking antihypertensive drugs: chronic hypertensive patients, blood pressure rises in the morning, lowers after taking drugs, and rises again in the afternoon. This is not a precursor of the disease, but is probably related to the type of antihypertensive drugs and the time of taking them. Therefore, as long as the time to change the medication, changed to breakfast and afternoon to take, or change the antihypertensive drugs can be.
2. Change of seasons: Older people may experience unstable blood pressure due to the change of temperature during the change of seasons.
3. Pheochromocytoma: when the patient’s blood pressure is drastically unstable, suddenly the blood pressure is very high, and suddenly low blood pressure, the patient may suffer from pheochromocytoma, and at this time, he should go to the hospital as early as possible for examination and treatment as soon as possible.
When measuring blood pressure, the patient should be allowed to sit still for 5 to 10 minutes, and then take blood pressure measurement after he/she relaxes.
