Can Janumet cause vision probs & should you take Metformin if you can control Blood Sugar w/out it?

You bring up some excelent points! First, I want to commend you on your excelent numbers and loosing all that wegiht. Good work, keep it up! Since Janumet is combination of both Januvia and Metformin, I will adress both seperatly.

1) Januvia has not been reported to cause vision problems, neither has metformin. There are a couple of possibilities that I see. First, even though it is less likely with these two meds, you could still get hypoglycemic. If you are hypoglycemic you could have vision problems. However, it doesn't sound like you are that low when this happens. The second possibility is the natural course of diabetes. Have you hade your eyes checked? That is a need-to check for all diabetics to look for diabetic retinopathy.

2) There is a lot of evidence that shows metformin is good to prevent further complications from diabetes. So yes you could still take it, as it is less likely to cause hypoglycemia.

However, all these discusions should also take place with your endocrinologist or primary care doctor.
