If diabetic patients experience dizziness, it may be due to high blood sugar or high blood pressure resulting in insufficient blood supply to the brain, patients can take oral medications to improve the blood supply to the brain, such as Nimotropic or Cipro and other medications can be effective in relieving the symptoms of dizziness. If the patient’s blood sugar and blood pressure are under control, and the symptoms are still not relieved after taking drugs to improve dizziness, the patient should go to the hospital in time to have a brain CT or brain MRI, in order to exclude whether there is the possibility of cerebral infarction. Because patients with cerebral infarction may also show persistent dizziness, if diagnosed with cerebral infarction after examination, patients need to be hospitalized in time for systematic treatment.
