Mild hypotension has no effect on the body and may result in dizziness, loss of appetite, weakness, headache, pallor and other abnormal manifestations, while severe hypotension can lead to inadequate perfusion of vital organs. Inadequate cerebral perfusion can lead to cerebral ischemia and, in severe cases, to the formation of cerebral infarction, which can lead to dizziness, numbness of the limbs, and even impairment of limb function and speech. When coronary artery insufficiency is caused, symptoms of myocardial ischemia will appear, and patients will experience chest pain, chest tightness, and difficulty in breathing. When it leads to inadequate perfusion of the kidneys, there is hyperalgesia, and it is especially important to be aware of the possibility of leading to acute renal failure. Other hazards of hypotension are also more serious, such as patients who experience syncope can easily fall and cause damage to body parts. Patients with hypotension should rest adequately, monitor the degree of blood pressure reduction, and if the patient’s diastolic blood pressure is below 60 mm Hg and systolic blood pressure is below 90 mm Hg, seek prompt medical attention to determine the cause of the hypotension and to fully consider whether the hypotension is affecting the perfusion of vital organs, and to develop the most effective treatment according to the specific situation.
