Is type 1 diabetes hereditary or can it develop later?

Question

Hello doctor,

I have a few questions regarding my uncle, who has been diagnosed with type 1 diabetes. I always thought type 1 diabetes was something children are born with or develop early in life, and that it is more common in kids.

Can adults also develop type 1 diabetes later in life? Is that what may have happened in my uncle’s case?
I am also curious about what causes type 1 diabetes. Is it mostly genetic, or are there other factors involved?
If someone is diagnosed with type 1 diabetes as an adult, how is it typically managed?
It seems like a very challenging condition to live with, especially when it starts later in life. Does it affect the body differently when diagnosed in adulthood compared to childhood?
Is type 1 diabetes a lifelong condition, or is there any chance of recovery?

I am genuinely concerned about my uncle’s health and would appreciate any guidance.

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

Thank you for reaching out. I understand your concern, and I appreciate you taking the time to learn more about your uncle’s condition.

Type 1 diabetes is generally considered an autoimmune condition that may have a genetic component. While it is more commonly diagnosed in children and adolescents, it can also develop in adults, a condition sometimes referred to as latent autoimmune diabetes in adults (LADA).

To confirm a diagnosis of type 1 diabetes, we typically order specific blood tests such as:

GAD (glutamic acid decarboxylase) antibodies.
Islet cell antibodies.
Zinc transporter (ZnT8) antibodies.
C-peptide and fasting insulin levels, which help assess insulin production by the pancreas.

Once diagnosed, type 1 diabetes is managed with insulin therapy. While it does require consistent care and monitoring, with proper education and support, many individuals live healthy, full lives. It is important to note that type 1 diabetes is a lifelong condition, but it is manageable and not something to be feared.

Thank you.
