Many of us only know that high blood pressure, one of the “three highs”, is dangerous to human health, but we do not know that low blood pressure is even more dangerous to human health. Hypotension refers to a state in which the arterial pressure in the body circulation is lower than normal. It is generally considered to be low when the arterial pressure in the upper extremities of adults is less than 90/60 mmHg. Hypotension usually makes people feel tired and depressed, limbs are weak, headache, dizziness, black eyes and dizziness in mild cases; in severe cases, they can lose concentration and even faint; sweating, pale skin or mild cyanosis, hot and cold, ants crawling, numbness of hands and feet, etc.; loss of appetite, abdominal discomfort, indigestion, and reduced resistance to infection and other signs. It can be seen that hypotension is extremely harmful to the human body, and in serious cases, it can also induce cerebral infarction, cerebral ischemia and cerebral hypoxia symptoms, which can lead to dizziness, memory loss, insomnia. Mania and emotional disturbance. The heart and kidneys can also have a range of symptoms. Low blood pressure is bad for health and peace, but the dangers of high blood pressure are equally not to be ignored. Hypertension is primarily a syndrome, a combination of the central nervous system of the brain and various organs. For example, the central nervous system causes headaches, dizziness, memory loss, and cerebrovascular changes due to increased blood pressure; hypertension reacts to the heart, causing panic and tightness in the chest and causing problems such as tachycardia, premature beats, cardiac hypertrophy, and heart failure. It can be seen that it is really impossible to compare between low blood pressure and high blood pressure, which is more important, and these two cannot be compared, each has its own hazards, which cannot be ignored. No matter which blood pressure abnormality is present, the consequences are incalculable if not treated properly.
