My cousin has type 1 diabetes. Can diet help control sugar?

Question

Hello doctor,

My cousin is 19 and was diagnosed with type 1 diabetes three years ago.

His HbA1c last week was 8.9 % even though he takes Insulin four times daily. CGM readings show frequent nighttime lows, too. My concerns are -

Are there new Insulin pumps or hybrid closed-loop systems that help control sugar better?
Can lifestyle or specific diet patterns, such as low-carb, help type 1 cases?
Also, how can we prevent long-term problems like kidney or nerve damage?
He sometimes skips a dose during college. How serious can that be if sugars look okay in the short term?

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

It is excellent that your cousin is checking his blood sugar levels carefully and using a continuous monitor.

Your cousin’s HbA1c (glycated hemoglobin) level shows that his overall control can improve, and as you mentioned, his sugar levels are swinging, which is quite common in young adults on multiple injections, especially with an active lifestyle and irregular meals.

The new Insulin pumps with hybrid closed-loop systems can help. These link the Insulin pump to a CGM (continuous glucose monitoring) and automatically adjust background Insulin, correcting sugar levels on their own. So, he would have far fewer worries about highs and lows.

If he prefers to stay on injections, we can still fine-tune things by switching to an ultra-long-acting basal Insulin (like Degludec) and a faster meal insulin. This approach can be very useful for him.

Diet and lifestyle always matter, but in type 1 diabetes, Insulin remains the cornerstone.

A moderate-carbohydrate plan with consistent meal timing is beneficial.
Completely cutting out carbohydrates is not needed and can even be risky.
The goal is steady, balanced meals including whole grains, vegetables, and lean proteins.
Regular exercise is excellent, but should be planned. A little less insulin or a small snack before activity usually prevents post-exercise lows.

Long-term complications involving the kidneys, eyes, nerves, and heart are almost entirely preventable today.

The key is keeping sugars in range most of the time and doing annual kidney and eye checks. The risk of problems drops dramatically when the HbA1c stays near seven percent and lows are avoided.

About skipped doses, even missing Insulin once in a while can be dangerous. Without Insulin, blood sugar can rise quickly, and ketones can build up, leading to serious complications. It is not worth the risk, even if readings look okay for a short while.

I hope this helps.

Thank you and take care.

Regards.
