My HbA1c is 8.2. Should I start insulin or GLP-1?

Question

Hello doctor,

I am a 54-year-old male, overweight (BMI, also known as body mass index, is 31), and recently diagnosed with type 2 diabetes. My fasting sugar is 162 mg/dL, and HbA1c (hemoglobin A1c test) is 8.2 percent. I have started Metformin, but I still feel tired, thirsty, and unable to lose weight. My father had kidney failure due to diabetes, so I am very concerned about long-term complications.

Should I start insulin early?
Would newer options like SGLT2 (Sodium-glucose cotransporter 2) inhibitors or GLP-1 (Glucagon-like peptide-1) injections be better for me?
Also, is intermittent fasting safe in my situation?
Could intermittent fasting cause harmful sugar fluctuations in my case?

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I completely understand your concerns, especially given your father’s history of kidney failure from diabetes. It is natural to want to act early and choose the best treatment path.

Your levels need tighter control with an HbA1c (glycohemoglobin or hemoglobin A1c test) of 8.2 percent and fasting sugar of 162 mg/dL. However, insulin is not usually the first step unless blood sugars stay uncontrolled despite other treatments.

Since you are already on Metformin but still have tiredness, thirst, and weight struggles, adding a newer medicine could help:

SGLT2 (Sodium-glucose cotransporter 2) inhibitors lower sugar and protect the kidneys and heart.
GLP-1 (Glucagon-like peptide-1) receptor agonists (injections) lower sugar, improve heart health, and support significant weight loss.

Both are often preferred before starting insulin in situations like yours.

As for intermittent fasting, it can be safe and sometimes beneficial for weight and sugar control in type 2 diabetes. But since your medicines may still change, it is best to do this under your doctor’s supervision to prevent large sugar swings.

You are asking the right questions at the right time. With the right mix of medication, lifestyle adjustments, and close follow-up, you can reduce risks and protect your kidneys and overall health in the long run.

I hope this answers your query.
