I am 24 with T1D. Can it cause long-term eye damage?

Question

Hello doctor,

I am 24 years old and recently diagnosed with type 1 diabetes. My fasting sugar was 178 mg/dL, and HbA1c was 9.1 %. The anti-GAD antibody test was positive.

My doctor started me on Insulin, but I am still seeing sugar spikes after meals. Sometimes I feel dizzy and have blurred vision. I also have mild tingling in my feet. So, I am looking for your suggestions on-

Should I get a C-peptide test to check pancreatic function?
Also, is it safe to follow intermittent fasting while on Insulin?
Can type 1 diabetes cause long-term nerve or eye damage?

I am worried because my weight is dropping rapidly, even though I am eating well.

Please suggest.

Hello,

Welcome to icliniq.com.

I understand your concern.

Being newly diagnosed with type 1 diabetes can feel overwhelming, especially as you adjust to Insulin therapy and monitor blood sugars.

Your high HbA1c (glycated hemoglobin) indicates that your glucose has been elevated for some time, which can explain symptoms like dizziness, blurred vision, and tingling in your feet.

A C-peptide test can be helpful to evaluate residual Insulin production and pancreatic function, which may guide your Insulin regimen, but it should be interpreted alongside antibody results and clinical status.

Rapid weight loss despite adequate eating is a common concern in type 1 diabetes due to Insulin deficiency, and proper Insulin dosing, along with balanced nutrition, is crucial to prevent further loss. Intermittent fasting is generally not recommended for people on Insulin because it can increase the risk of dangerous hypoglycemia and ketoacidosis.

Long-term uncontrolled type 1 diabetes can indeed lead to complications such as diabetic neuropathy affecting the nerves, retinopathy affecting the eyes, and nephropathy affecting the kidneys, but strict glucose control, regular eye exams, and foot care can significantly reduce these risks.

It is important to work closely with an endocrinologist and diabetes educator to optimize Insulin doses, manage post-meal spikes, monitor for complications, and maintain safe nutrition while stabilizing your blood sugar levels.

I hope this helps. Always feel free to reach out at any time. I am always here to help you.

Thank you.
