My wife's blood sugar is high despite Metformin. What else can help?

Question

Hello doctor,

My 41-year-old wife was just diagnosed with type 2 diabetes during a routine physical, and I'm shocked because she doesn't fit the typical profile. Her A1C came back at 7.8, and fasting glucose was 165, but she is only 20 pounds overweight and exercises regularly.

We got to know that she had gestational diabetes with both our kids, eight and five years ago, but doctors said it would go away after delivery. Her mother also developed diabetes in her 50s, so there might be a family history involved.

The endocrinologist started her on Metformin 500 mg twice daily, but it is giving her terrible stomach upset and diarrhea. She is also worried about how this diabetes diagnosis will affect her personal and professional life.

She has been trying a low-carb diet for two weeks, but her blood sugars are still running 180 to 220 throughout the day. Scared about long-term complications like kidney problems and vision loss.

Can stress make diabetes worse because she has been under a lot of pressure at work lately?

Kindly suggest.

Hello,

Welcome to icliniq.com.

I have read your query and understand your concern.

Many people believe type 2 diabetes only occurs in those who are very overweight or inactive, but in actuality, that is not always the case.

A history of diabetes during pregnancy is one of the strongest predictors of developing diabetes later in life, even many years after delivery, and a family history further increases that risk.

So while this feels sudden, it does fit a pattern we often see. Your wife's sugar levels indicate early but definite diabetes, not a late or advanced stage. At this level, the aim is to bring sugars down steadily and safely rather than expecting immediate normal readings in a couple of weeks.

Metformin-related stomach upset and diarrhea are extremely common, especially when started at full doses. This does not mean the drug cannot be used at all. Many patients tolerate it well when the dose is reduced, taken strictly after meals, or switched to a slow-release form.

This is something her treating doctor can easily adjust, and it often makes a big difference to comfort without losing benefit. Regarding complications, the reassuring point is that problems like kidney disease and vision loss develop over years of poorly controlled diabetes, not weeks or months.

When diabetes is detected early, as in your wife’s case, and sugars are brought under control, the risk of these complications drops dramatically. Regular eye checks and simple urine tests are done to monitor this, but there is no reason to assume damage has already occurred.

Stress absolutely can worsen blood sugar control. Ongoing mental and work-related stress raises stress hormones that push glucose levels up, even when diet and exercise are good. This does not mean stress caused the diabetes, but it can certainly make control harder until things settle.

I hope this answers your questions. Please follow up if you need anything else. I am here to help you.

Thank you.
