Low blood pressure does not affect erections. Normal work stress or emotional effects may cause erection difficulties, and the consequences of low blood pressure are highly related to the severity of the drop and its cause. If the blood pressure is low, but the degree of reduction is not particularly great and the patient’s general condition can be maintained, low blood pressure in this case is not a problem and the patient can usually enhance proper nutrition to raise the blood pressure. However, pathologically speaking blood pressure is very low, a condition that is usually malignant, such as malignancy or tuberculosis, in which the body is weakened, primarily through enhanced nutrition and increased circulating blood volume. If the blood pressure is persistently low, this may lead to hypotension, syncope and possibly even the development of hypotensive shock in the patient. Therefore hypotension is also serious and the cause must be treated aggressively. Long-term hypotension may lead to insufficient blood supply to the brain and ischemic attacks, as well as to insufficient blood supply to the coronary arteries and ischemic attacks to the heart muscle, so the consequences are very serious.
