Is it normal for diastolic blood pressure to be consistently above 90 mmHg but not reaching 100 mmHg?

Generally, "low pressure" refers to diastolic blood pressure. A long-term diastolic pressure above 90 mmHg but less than 100 mmHg is considered abnormal. The normal diastolic pressure for adults ranges from 60 to 90 mmHg. Diastolic pressure consistently above 90 mmHg falls outside the normal range and may be caused by factors such as poor diet, excessive stress, hypertension, arrhythmia, or coronary atherosclerotic heart disease. It is recommended that patients seek medical evaluation and receive appropriate treatment under medical guidance. Specific analyses are as follows:

1. Poor Diet

Consuming excessive salt can lead to high sodium levels in the body, increasing blood volume and resulting in elevated diastolic pressure. Patients are advised to maintain a light diet and avoid greasy or irritating foods.

2. Excessive Stress

Chronic mental tension and high stress levels may affect blood circulation, thereby influencing diastolic pressure. Patients should ensure adequate rest and work on relaxing their minds.

3. Hypertension

Hypertension refers to increased pressure of blood against the arterial walls. When hypertension is present, diastolic pressure also tends to rise. Patients may take medications such as metoprolol tartrate tablets, bisoprolol fumarate tablets, or losartan potassium-hydrochlorothiazide tablets as prescribed by a physician.

4. Arrhythmia

When heart rate increases, the cardiac diastolic phase shortens, reducing blood flow to peripheral tissues while increasing residual blood volume in the aorta, which may elevate diastolic pressure. Patients may use atenolol tablets, propranolol hydrochloride tablets, or furosemide tablets as directed by a doctor.

5. Coronary Atherosclerotic Heart Disease

This condition typically involves hardening of the coronary arteries, leading to impaired blood circulation and reduced cerebral perfusion, which may also result in elevated diastolic pressure. Patients may be prescribed medications such as simvastatin dispersible tablets, atorvastatin calcium tablets, or clopidogrel hydrogen sulfate tablets according to medical advice.

In addition, elevated diastolic pressure could also be caused by acute myocardial infarction. If patients experience any discomfort, they should promptly visit a hospital for targeted treatment to avoid delays in managing their condition.
