Numbness of the face and hands may be caused by respiratory alkalosis, cerebral blood supply insufficiency, acute cerebrovascular disease, etc., and the cause of the disease should be identified in a timely manner.
1. Respiratory alkalosis: it can often cause hyperventilation, as well as numbness around the lips and mouth, numbness of the hands and feet, and further development of the face and limbs may appear twitching or convulsions, and fainting may occur in severe cases.
2. Cerebral blood supply insufficiency: it is generally an obstacle of blood circulation in the brain, and the main manifestations include heavy head, dizziness, head swelling, headache, memory loss or inattentiveness, etc.; acute patients may have weakness of one side of the limbs, hemiplegia and numbness, perioral numbness of one side of the face, aphasia, impaired consciousness, and convulsions.
3. Acute cerebrovascular disease: if high blood pressure induces hemorrhagic cerebral stroke, hemiplegia may occur, i.e. numbness of face, tongue, hands or legs and feet, and dullness of sensation, which most often occurs on one side of the body, and is sometimes accompanied by tinnitus, hearing loss, or sense of rotation of the visual field.
The above symptoms alone are not enough to diagnose the disease, and may be caused by other factors. It is recommended that the patient should consult a doctor in time to clarify the cause of the disease and give targeted treatment.
