Dizziness and numbness of hands and feet may be caused by low blood sugar, low blood pressure, cervical spondylosis and other diseases. 1. Hypoglycemia: Some people may have hypoglycemia after strenuous exercise and large amount of sweating to consume energy, or they may have taken excessive glucose-lowering drugs and injected excessive insulin, which may also cause hypoglycemia, thus causing dizziness and numbness of hands and feet. 2. Low blood pressure: Low blood pressure will cause insufficient cerebral perfusion and poor blood circulation, thus causing dizziness, numbness of hands and feet and other symptoms. Therefore, we should avoid blindly using large quantities of antihypertensive drugs, and if necessary, we can take pressure-raising treatment in time. 3. Cervical spondylosis: due to the herniated intervertebral disc compressing the vertebral artery, causing insufficient blood supply to the vertebral artery can lead to dizziness; the herniated intervertebral disc compressing the nerves can cause numbness in the hands and feet. Dizziness, numbness of hands and feet may also be caused by other reasons, it is recommended that patients seek timely medical attention to identify the causes and carry out targeted treatment.
