Low blood pressure (diastolic blood pressure) is low and confusing, and transient cerebral blood supply insufficiency may exist, and it is also necessary to rule out the existence of hypovolemic shock and other problems. 1. Transient cerebral insufficiency of blood supply: When the diastolic blood pressure level drops, the patient experiences clinical symptoms of dizziness. The presence of insufficient blood supply to the vertebral basilar artery also induces insufficient blood supply to the brain, resulting in dizziness, accompanied by generalized weakness and confusion. 2. Hypovolemic shock: when blood pressure is too low, it will also lead to insufficient perfusion of brain tissues around the brain, and even induce hypovolemic shock, and the patient may have consciousness disorders, which will lead to the problem of confusion. Low blood pressure is too low, patients with symptoms of confusion, it is recommended to consult the cardiovascular department of the regular hospital.
