What is Diabetes?

Diabetes is a chronic, long-lasting and a group of metabolic disorder that affects how your body turns food into the energy. According to National Institute of Diabetes and Digestive and Kidney diseases , diabetes occurs when your blood sugar level remains high due to deficiency or improper functioning of insulin.

Basic pathology of Diabetes

When we eat food, it converts into glucose and provides the energy to our body. Pancreas secreted a hormone called insulin. Insulin helps in glucose get into your cells to give them energy.

Sometimes your body either does not make enough insulin or does not use insulin properly. Because of this improper functioning of insulin, glucose stays in the blood.   It does not reach the cells. This raised blood sugar level leads to various sign symptoms in your body. Clinically, this condition is called diabetes.

Over the time, if this raised sugar level left untreated, it causes heart diseases, nerve damaged, eye problems and kidney diseases.

Diabetes data worldwide

There are some shocking scientific facts about this “Silent killer disease”.

  • According to WHO, in 2015 an estimated 1.6 million deaths were directly caused by diabetes. And WHO projects that diabetes will be the next leading cause of death in 2030.
  • The global prevalence of diabetes among adults over 18 years of age has risen from 4.7% (in 1980) to 8.5% in 2014.
  • Globally as estimated that 422 million adults were living with diabetes in 2014, compared to 108 million in 1980. And this ratio is increasing frequently.

Indeed, these facts are shocking and dreading too.

Type of diabetes

    Types of diabetes

Type 1 diabetes

It is also called insulin-dependent or juvenile diabetes. It is less common than type 2 diabetes. It is usually diagnosed in teens and young adults.  But it can develop at any age.


With type 1 diabetes body does not make insulin. Your immune system destroyed the cells in the pancreas that make insulin. People with type 1 diabetes need to take insulin every day to stay alive.

Type 2 diabetes

It is a most common type of diabetes. In this type, the body does not use insulin well and this thing results in raised glucose level. It is more commonly diagnosed in adults. It can be delayed or prevented, by paying close attention to your lifestyle factors. It includes diet and regular exercise. Also, the regular check-up is equally important to diagnose it early.

People with diagnosed type 2 diabetes need to get regularly prescribed medication to maintain the blood sugar level. Otherwise, serious health complications can occur, that may lead to death.
