Patients with low blood pressure may also induce symptoms of dizziness and headache, but if the headache is still present after the blood pressure rises, it is not considered to be caused by low blood pressure. When a patient has low blood pressure, it is recommended that he or she take an oral pulse drink to raise his or her blood pressure and that he or she identify the cause of the low blood pressure. If the headache persists after the blood pressure is corrected, further examination of transcranial Doppler and head CT is recommended, as the headache may be caused by cerebral infarction or lacunar cerebral infarction, cerebral vascular spasm, or insufficient blood supply to the cerebral arteries. In addition, migraine and vasoneurotic headache may be the cause of headache. If the headache is caused by vascular spasm, patients are advised to take oral medication such as Cipro. If the headache is caused by insufficient blood supply to the cerebral arteries, oral medications such as Jinaduo or blood-supporting and brain-clearing pellets can be taken to help improve the symptoms. During the day, patients are also advised to pay attention to regular work and rest, avoid straining and staying up late, and good lifestyle interventions can also help improve low blood pressure and headaches.
