The rise in blood pressure at night may be caused by bad habits, drug effects, sleep apnea syndrome and other factors.
1. Bad life habits: it may be because patients stay up late for a long time, dietary indiscipline, often drink high concentration of coffee, difficult to sleep and other factors lead to the body’s blood pressure circadian rhythmic disorders, thus appearing in the evening the phenomenon of increased blood pressure.
2. Drug effects: If the patient has a history of hypertension, when taking antihypertensive drugs, due to the short duration of the effect of the drugs taken, can not stabilize the body’s blood pressure value for a long time, or due to individual resistance to different drugs, resulting in taking the drug in the night time failure, thus appearing in the night blood pressure value rises.
3. Sleep Apnea Syndrome: The phenomenon of high blood pressure at night in some patients may also be caused by sleep apnea syndrome. The narrowing of the upper respiratory tract and the weakening of the pharyngeal muscle tone can lead to intermittent hypoxia, and the blood vessels are stimulated to constrict and cause an increase in blood pressure, accompanied by fatigue, waking up, apnea, sweating and other symptoms.
There are other factors that may lead to high blood pressure at night, such as obesity, hormone secretion abnormalities. It is recommended that patients with unexplained elevated blood pressure must consult a doctor in a timely manner, after examination by a doctor, to clarify the cause of the disease and target treatment.
