A blood pressure of 155/85 mmHg, if hypertension has been diagnosed, has met the diagnostic criteria for hypertension class 1, and treatment options include medication, diet and exercise. Hypertension class 1 is defined as having a systolic blood pressure of 140-159 mmHg and/or a diastolic blood pressure of 90-99 mmHg on at least 3 non-same days; therefore, a blood pressure of 155/85 mmHg has met the diagnostic criteria for hypertension class 1, and should be treated with medication, diet, and exercise under the supervision of a physician. Blood pressure 155/85mmHg can be preferred to monotherapy under doctor’s guidance, such as diuretics (hydrochlorothiazide, furosemide, torasemide, etc.), β-blockers (metoprolol), calcium channel blockers (nifedipine, nilprednisolone, etc.), and angiotensin II receptor antagonists (valsartan, irbesartan, chloretan, etc.), and the changes of blood pressure should be closely monitored during the treatment. In addition to medication, patients are advised to eat a low-salt, low-fat, low-cholesterol diet, eat more fresh fruits and vegetables, supplement proteins, and engage in appropriate exercise to maintain stable blood pressure. Hypertensive patients should take medication regularly, monitor their blood pressure under the guidance of their doctors, and maintain healthy lifestyle habits and work routine, and seek prompt medical attention if they feel unwell.
