I am 19, male. How can I manage T1D with celiac disease?

Question

Hello doctor,

I am a 19-year-old male who was diagnosed with type 1 diabetes at the age of 12, and I have been on a basal-bolus insulin regimen since then. Despite regular injections, my blood sugar levels fluctuate a lot, with fasting values sometimes as low as 65 mg/dL and post-meal readings going up to 280 mg/dL. My last HbA1c was 8.6%, which shows poor control, and I often experience symptoms of hypoglycemia like sweating, shakiness, and confusion, especially at night.

I also have celiac disease, diagnosed two years ago, and following a strict gluten-free diet is quite challenging. My weight is 114 pounds at a height of 5.5 feet, giving me a BMI of 18.4, which is slightly underweight. My lipid profile is normal, but my recent urine microalbumin was borderline high at 32 mg/g, which makes me worried about early kidney problems.

Sometimes, I skip insulin doses when I am busy or unwell, and this has led to high sugars and ketones in the past. I feel anxious about long-term complications like eye and kidney damage, and I am not sure if switching to an insulin pump or CGM would help improve my control.

Could you please guide me on how best to manage type 1 diabetes along with celiac disease, and whether newer technologies or lifestyle strategies could help stabilize my sugars?

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern.

You have highlighted all the right points that matter in your case. You are dealing with type 1 diabetes, celiac disease, underweight BMI (body mass index), variable blood sugars, and early microalbuminuria risk.

Understanding your current situation:

Blood sugars: Wide swings (65 to 280 mg/dL), reflecting a mismatch between insulin, meals, and activity.
HbA1c 8.6%: Indicates high average sugars with significant variability.
Night-time hypoglycemia: Possibly due to excess basal insulin or a mismatched evening dose or meal.
Celiac disease: Makes consistent nutrition harder; a gluten-free diet can limit calorie or protein intake, which explains your underweight BMI (18.4).
Microalbuminuria (32 mg/g): An early warning sign of kidney stress, but still reversible with good control and kidney protection.
Skipped insulin doses: Very risky (increases risk of diabetic ketoacidosis and other complications).

The probable cause in your case is mismatched meals and insulin doses. I suggest you follow this:

Discuss with your doctor about starting a CGM (continuous glucose monitor).
Review basal insulin dose because night-time lows suggest possible reduction.
Work with a dietitian experienced in diabetes and celiac disease to create a hostel-friendly gluten-free meal plan.
Never skip insulin. If sick or unable to eat, follow sick-day rules (fluids and monitor ketones).
Recheck microalbumin in three to six months.

With your age, access to technology (CGM and pump), structured carbohydrate counting, and strict gluten-free nutrition, you can stabilize blood sugars, gain weight, and prevent long-term complications.

I hope this helps you.

Thank you.
