What Causes Type 2 Diabetes?

What is Type 2 Diabetes?

Type 2 diabetes is a metabolic disorder that interferes with the body’s ability to utilize the insulin that has already been produced. When the body is unable to produce enough insulin, one is diagnosed with type 2 diabetes.

This illness puts your body in distress in such a way that it struggles to metabolize a simple sugar, such as glucose. Thereafter, the uncontrolled levels of the glucose flood around the bloodstream which may cause further damage to vital organs, such as the pancreas.

When diagnosed, the severe effects of this type of diabetes are so severe that patients are advised to be strict with their diets and medication. An ordinary dish that qualifies as perfectly fine for other people might be toxic to those who suffer from type 2 diabetes. However, most of them only have to avoid dietary sugar and they will be fine.

Type 2 diabetes is the most common type of diabetes. Formally, it was known as non-insulin dependent diabetes or adult-onset since it mostly affected adults. However, adolescents and even small children have been diagnosed with type 2 diabetes hence this term is no longer used to define it.


What Are The Causes of Type 2 Diabetes?

Insulin, sugar and apple

Type 2 diabetes will occur when the insulin hormone is unable to be fully utilized by the cells in your body. Cells depend on insulin in order to absorb glucose from the bloodstream. This glucose is later converted into energy which facilitates activity within and outside of the body. To learn more about blood sugar levels click here.

With such difficulty, your body develops type 2 diabetes which renders your body resistant to insulin. Normally, your pancreas will detect a shortage of insulin then produce more of it.

With time, it will be unable to satisfy the need necessary to keep the blood sugar at normal levels. When this happens, your sugar will build up in your blood instead hence the need for medication to lower and maintain it at healthy levels.

Only a blood sugar test can accurately detect type 2 diabetes. The earlier the diagnosis and onset of medication, the higher your chances of proper management without being at risk of adverse effects.

If proper care is not taken or if diagnosis takes too long, you will be at risk of life-threatening side effects such as; kidney failure, amputation, heart disease, stroke.

Research conducted in 2011 showed that more than 36 genes contribute to the development of type 2 diabetes.

However, only 10% of a combination of these genes account to the development of a type 2 diabetes case.

Type 2 diabetes is a serious illness that requires the use of insulin or anti-diabetic drugs to keep the blood sugar level under control. If there’s a family history of this type of diabetes within your close relatives, you will need to notify your doctor during your routine health check-ups.

This way, the will blood sugar check-ups will be scheduled in order to stay ahead of the illness. If detected early, management becomes easy. It rules out chances of developing adverse effects and organ failure in the future.
