metformin can help with weight loss, but typically like 10-15 lbs in someone that needs to lose it... and it's just an aid. I would say there is another reason... age, eating habits, etc.
Metformin is a very general medicine for diabetes.It can't cause weight loss.
Metformin (Glucophage) must be taken with food otherwise it may cause nausea or vomiting, gas, ingestion, and abdominal discomfort leading to loss of appetite and, of course, excessive weight loss. Your mother might want to switch to the long-acting form of Metformin, called Metformin ER, which has fewer side effects in patients. Please discuss this with her doctor.
Correction: meant to say indigestion not 'ingestion'.

Yes Metformin can cause weight loss, I lost about 25 needed lbs real quick with a low carb, nothing white diet. I have tried not very successfully before metformin and did not lose the weight. My weight loss has slowed down since I got over the intial scare of being diagnosed with type 11 diabetes. and learn more of what I can eat and what I should not. My best to you mom...
