Causes of Diabetes

There is no one common diabetes cause
There is no one common diabetes cause
Diabetes causes vary depending on your genetic makeup, family history, ethnicity, health and environmental factors.

There is no common diabetes cause that fits every type of diabetes.

The reason there is no defined diabetes cause is because the causes of diabetes vary depending on the individual and the type.

For instance; the causes of type 1 diabetes vary considerably from the causes of gestational diabetes.


Similarly, the causes of type 2 diabetes are distinct from the causes of type 1 diabetes.

Causes of type 1
Causes of type 1 include genetics, viral infection and several other triggers.

Causes of type 2
Type 2 causes include diet, obesity and ethnicity.

Causes of type 2

Type 1 diabetes is caused by the immune system destroying the cells in the pancreas that make insulin. This causes diabetes by leaving the body without enough insulin to function normally.

This is called an autoimmune reaction, or autoimmune cause, because the body is attacking itself.

There is no specific diabetes causes, but the following triggers may be involved:

Viral or bacterial infection
Chemical toxins within food
Unidentified component causing autoimmune reaction
Underlying genetic disposition may also be a type 1 diabetes cause.

Type 2 diabetes causes

Type 2 diabetes causes are usually multifactorial – more than one diabetes cause is involved. Often, the most overwhelming factor is a family history of type 2 diabetes.

This is the most likely type 2 diabetes cause.

There are a variety of risk factors for type 2 diabetes, any or all of which increase the chances of developing the condition.
