Type 1 Diabetes: Causes, Symptoms, Diagnosis and Treatment

Diabetes has been affecting more people globally and around 10 percent of the patients suffer from type-1 diabetes.

Diabetes occurs when the pancreas, a gland behind the stomach, does not produce enough of the hormone insulin, or the body can't use insulin properly.

Insulin is an essential hormone and allows the transfer of glucose from the blood to the cells in order to produce energy. This leads to the build up of the glucose and gives rise to symptoms of diabetes.

What is type-1 diabetes? What are the causes, symptoms and treatment for the disease?

Type-1 Diabetes: Causes

Type-1 diabetes is the autoimmune disease that is caused due to autoimmune destruction of the beta cells in the pancreas. This leads to low levels of insulin in the blood, higher levels of glucose in the blood due to restriction in mobilisation of glucose from the blood to the cells.


The destruction of beta cells may be either due to genetic problems in which the body treats the beta cells as foreign bodies or due to external stimuli like a viral infection.

In type-1 diabetes, body cannot produce enough insulin whereas in type-2 diabetes body becomes resistant to insulin.

  • A1c test is taken every 3 months and it indicates the percentage of sugar in the blood. The result equal to or higher than 6.5 percent is considered to be diabetic.
