My HbA1c is 8.4 despite Metformin. Will a low-carb diet help?

Question

Hello doctor,

I am 44 and recently diagnosed with type 2 diabetes. My HbA1c came back at 8.4 %, and fasting glucose was 178 mg/dL. I have been started on Metformin 500 mg twice daily, but I still notice frequent urination and constant fatigue.

Also, my lipid profile showed high triglycerides of 248 mg/dL, and my doctor warned me about heart risks. So my concerns are-

Should I request an early microalbuminuria test to check for kidney damage?
Also, how soon can lifestyle changes like a low-carbohydrate diet and exercise start showing results on my sugar levels?
Are CGM devices really helpful in controlling daily fluctuations?

Kindly suggest.

Hello,

Welcome to icliniq.com.

I understand your concern.

I am really sorry you are dealing with all this. It can feel overwhelming at first, but it is good that you have already started treatment and are asking the right questions.

With your HbA1c (glycated hemoglobin) at 8.4 % and fasting sugar of 178 mg/dL, your symptoms of fatigue and frequent urination are typical signs of poor glucose control, and Metformin alone may take several weeks to show its full effect.

Early testing for microalbuminuria is definitely reasonable in your case, since diabetes and high triglycerides increase kidney and cardiovascular risk, and catching any early kidney involvement allows timely treatment with kidney-protective medications if needed.

The encouraging part is that lifestyle changes, especially regular physical activity and a diet lower in refined carbohydrates and sugars, can begin improving glucose and energy levels within weeks, and consistent effort over three to six months can bring a significant drop in HbA1c.

CGM (continuous glucose monitoring) devices can be very helpful, especially in the early stages, because they let you see how meals, stress, or exercise affect your sugar in real time, which makes it easier to stay on track and avoid hidden spikes.

Since you also have high triglycerides, focusing on weight management, regular exercise, limiting sugary foods and alcohol, and possibly adding medications like a statin if your doctor suggests, will go a long way in lowering your future heart risk.

Please do not be discouraged early. A consistent action really makes a difference, and you are already taking the right steps.

I hope this helps.
