Can T1D develop in a young male after a viral infection?

Question

Hello doctor,

My 22-year-old cousin has gained a significant amount of weight over the past year, and his blood sugar was measured at 230 mg/dL after eating. He is always tired and has noticed occasional blurry vision. There is no history of diabetes in our family, but he did experience a severe viral infection last year from which he never fully recovered. Could this have triggered type 1 diabetes? His fasting insulin levels were very low, and he has dark patches on his neck, which I believe may be acanthosis. Is it possible for him to have both type 1 diabetes and a condition similar to PCOS, even though he is male? We are unsure about which tests to request. His recent cholesterol test was normal, but his liver enzymes were slightly elevated.

Kindly help.

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern.

The symptoms of high blood sugar levels, fatigue, blurry vision, and very low fasting insulin suggest diabetes, likely type 1 or possibly type 2, given his weight gain and the presence of acanthosis nigricans (a skin condition characterized by dark, velvety patches in body folds and creases, often associated with insulin resistance or underlying health conditions), a marker of insulin resistance.

A severe viral infection in the past year may have triggered autoimmune destruction of the insulin-producing beta cells, potentially leading to Type 1 diabetes (T1D). However, weight gain and acanthosis are more typical of type 2 diabetes (T2D), suggesting a complex clinical picture that requires further investigation.

To differentiate between T1D and T2D, specific tests such as autoantibody screening (e.g., glutamic acid decarboxylase antibodies, islet cell antibodies) can help confirm an autoimmune origin, which is characteristic of T1D. Additionally, a C-peptide test can measure endogenous insulin production and clarify the diagnosis.

Elevated liver enzymes may indicate fatty liver disease, commonly associated with insulin resistance. Although polycystic ovary syndrome (PCOS) is exclusive to females, other hormonal imbalances (e.g., hypogonadism) could contribute to his symptoms.

A plan for these tests is crucial for a definitive diagnosis and appropriate treatment plan.

Early intervention with insulin therapy for T1D or glucose-lowering agents for T2D, along with lifestyle changes, is essential. Regular monitoring of blood sugar levels, liver health, and weight will help manage his condition effectively.

I hope this information helps you.

Thank you.
