Patient's Query

Hi doctor,

I have type 2 diabetes mellitus, and I take my daily medications. I have begun to experience lightheadedness and have to hold onto a wall. My doctor told me that my exercise and medications are controlling my diabetes. I take Metformin 500 mg daily. I have also been under medication for depression, and I seldom walk now. Since I am not walking, could this be the cause of my lightheadedness?

Welcome to icliniq.com.

Not exercising or walking could be one reason. Another reason could be cervical spondylosis.

  1. Use a soft cotton pillow and lie straight on the bed.
  2. Do not keep arm under the head while sleeping.
  3. Do mild neck exercises for strengthening.
  4. Get an x-ray of the cervical spine to rule out.

Next could be diabetic neuropathy. It is due to uncontrolled diabetes or long-standing diabetes. Make sure your blood sugar is within the normal range. If required, modify or alter the dosage of Metformin. In this case, you gradually start developing numbness in hands, fingers, lightheadedness. If you are overweight, weight reduction to reach normal limits should be a priority. Diet control is another essential factor in this case. You must cut down on sweets, sugar, fried, excessive oils, fat, etc. Consume a simple nutritional healthy balanced diet. Drink plenty of water, especially when you get up in the morning, drinking at least two glasses of water should be considered. Make sure you start to exercise, maybe walk, or yoga, etc., gradually. Please get your fasting blood sugar checked often. Also, keep a close watch on your health and bring blood pressure checked often. Full body checkup should be done once in six months as people with diabetes are at risk of developing other disorders. You may follow up for further details.

Same symptoms don't mean you have the same problem. Consult a doctor now!
