Blood pressure 150/100mmhg (100~150) after a cold is normal if it is transiently elevated, while it is not normal if there is a history of hypertension, and prompt medical treatment is recommended. Clinically normal adults in a quiet state, the normal value of blood pressure is 100~120/60~80mmhg, if the average of three times not measured on the same day, systolic blood pressure ≥ 140 and/or diastolic blood pressure ≥ 90mmhg can be diagnosed as hypertension, and blood pressure 150/100mmhg belongs to the range of secondary hypertension. If the blood pressure of 150/100 mmhg is due to a transient elevation after a cold, it will usually return to normal after the cold is cured. If there is a history of hypertension, it is an abnormal condition and requires prompt medical attention. Lifestyle interventions, such as smoking cessation and alcohol restriction, increased exercise to improve cardiovascular regulation and adaptive capacity, and if necessary, antihypertensive drugs such as hydrochlorothiazide, metoprolol, amlodipine, enalapril, etc., can be prescribed for treatment. Usually after the cold blood pressure 150/100mmhg, it is recommended to consult the cardiovascular internal medicine department in a timely manner, after the doctor’s comprehensive assessment of the condition of the treatment, not blindly use their own medication.
