Mild hypertension is generally referred to as hypertension grade 1, which is defined as a blood pressure with a diastolic blood pressure between 140 and 159 mmHg and/or a diastolic blood pressure between 90 and 99 mmHg. Some patients may be asymptomatic, and those who are symptomatic mainly show dizziness, headache, chest tightness, and scalp numbness. 1. Asymptomatic: Not all patients with mild hypertension will necessarily have uncomfortable symptoms. Some of them are only found to have elevated blood pressure during physical examination. 2. Symptomatic people: The main manifestations are dizziness, headache, chest tightness, scalp numbness, etc.. The occurrence of these symptoms is related to the increase in cerebral blood perfusion after the elevation of blood pressure, which leads to brain cell edema. Numbness of the scalp may occur if other factors are present that affect blood circulation to the scalp. Patients with high blood pressure should consult the cardiovascular medicine department of the hospital in time and take reasonable treatment under the guidance of the doctor so as not to affect their personal health.
