Low blood pressure is dangerous.

Low blood pressure for a long time can bring great damage to the body, causing insufficient blood supply to the body, resulting in fatigue, weakness, palpitation, shortness of breath, dizziness, insomnia and a series of clinical symptoms. Severe hypotension can even cause ischemia and hypoxia of important organs, resulting in changes in organ function, and serious cases can endanger life. Common are hemorrhagic shock, anaphylactic shock, cardiomyopathy, and hypotension caused by heart failure. This hypotension can often endanger the patient's life. Hypotensive patients can also show renal failure, because hypotension makes the perfusion pressure of the kidneys insufficient and shows uremia caused by the accumulation of metabolic waste in the body.
