Blood pressure is normal in the morning and high in the afternoon. Life interventions and medications should be chosen according to the specific situation. 1. If the blood pressure is normal in the morning and high in the afternoon, and if it is still within the normal range and there are no other symptoms, general treatment can be chosen without the use of drugs. General treatment is mainly life intervention, including light diet, limiting sodium intake, reasonable work and rest, less staying up late, appropriate exercise, close monitoring of blood pressure, and prevention of complications. If there is any discomfort, seek medical attention immediately. 2. If the blood pressure is out of normal range and reaches hypertension grade 2, medication can be used. Commonly used drugs are diuretics, such as furosemide, spironolactone; angiotensin-converting enzyme inhibitors, such as captopril. The choice of specific drugs needs to be determined by a professional doctor based on clinical symptoms. If you are already taking antihypertensive drugs, but your blood pressure is high in the afternoon and out of the normal range, it is recommended that you seek immediate medical attention and consult your doctor about whether you need to change your medication or use a combination of drugs.
