Long-term low blood pressure can lead to general weakness, loss of appetite, palpitations, shortness of breath, dizziness, and blackouts. Due to the excessively low blood pressure, the important organs suffer from ischemia and hypoxia, causing symptoms of ischemia and hypoxia in various organs, especially cerebral hypoxia, which can manifest as nausea, vomiting, headaches, blackouts, and even fainting. Therefore, low blood pressure should be actively treated and improved. Severe low blood pressure requires the use of medications, replenishment of blood volume, and appropriate application of certain vasopressor drugs to raise blood pressure and maintain adequate blood supply to important organs.
