What Can Cause Sweating, Dizziness And Numbness In The Leg While Being Treated For Type 2 Diabetes?

I have been diagnosed with type 2 diabetesand have been taking Metformin for a year. My sugar levels are always betwee 4.0 and 7.6 Yesterday I walked to work and I was walking home when my feet went numb and then my legs went numb. I had trouble moving them and then felt like I was going to faint. I just made it to a fence to hold myself up. I was sweating and dizzy. In about 5 minutes everything was normal and finished walking home. Today I have been normal. My friends thought maybe my blood sugar was too low. It was very scary.

Hello,

An episode of sweating, dizziness, numbness in diabetes on oral anti-diabetic (Metformin) could be due to hypoglycemia.

Alternatively, the episode may be related to bradyarrhythmia leading to near syncope (about to faint).

Blood sugar profile (fasting & post-postprandial) and ECG 12 leads with long lead II for 1 minute should be done as initial work-up.

Hope I have answered your query. Let me know if I can assist you further.

Take care

Hello,

You can not have low blood sugar with metformin. I would suggest seeing a neurologist.
