The causes of hypotension are usually the following for male patients: 1. Non-neurological causes, such as insufficient blood volume, dehydration, bleeding, severe burns, burns, etc., can lead to a drop in blood pressure, and in cases of severe shock, patients can also suffer from an obvious lack of blood volume, leading to a drop in blood pressure. 2. Endocrine metabolic diseases, such as thyroid insufficiency and hypoadrenocorticism, can also lead to low blood pressure in male patients. 3. 3. When adverse drug reactions occur with certain drugs, such as infusion reactions after the patient has used the drug, a drop in blood pressure can also occur. 4. Low blood pressure can also occur under the effect of neurological and humoral endocrine disorders. 5. If the patient is bedridden, febrile, or has chronic cardiac insufficiency for a long period of time, this can also lead to lower blood pressure.
