Why obesity causes diabetes?

why obesity causes diabetesIf you are overweight then you have a greater risk of developing type 2 diabetes. However, not everyone who is overweight develops this condition.  There are different factors that drive to type 2 diabetes and the main causing factors are genetics and lifestyle.

If you have extra fat, especially around your abdomen area, it can increase your risk of type 2 diabetes because it changes the way your body responds to insulin.

In order to understand why obesity causes diabetes, you first have to know about the condition in type 2 diabetes.

Type 2 diabetes is a condition in which the body becomes resistant to the salutary action of insulin and gradually loses the capacity to produce required insulin in the pancreas.

According to a particular study, it advocates that being overweight stresses the inner parts of individual cells. Specifically, overeating  stresses the membrane system within cells called Endoplasmic Reticulum (ER).

When the Endoplasmic Reticulum has more nutrients to process then it can handle, it sends a warning sign telling the cell to reduce down the insulin receptors on the cell surface.

This leads to insulin resistance and high blood sugar in the blood, which is prime causes diabetes.

Weight loss should be an important goal for an obese person, especially for people with type 2 diabetes.  

 A moderate weight can help improve insulin action and lessen the blood sugar in the blood.

How to know that you are overweight

Most people don’t even know that they are overweight. They are only realized when they are seriously fat.  The best way to know whether you are overweight or obese is by figuring out your Body Mass Index (BMI). It helps you to calculate your normal weight in comparison with your height.  

Generally, a BMI of-

  • 18 to 25 is considered to be normal or healthy.
  • 25 to 30 is considered as overweight.
  • 30 to 35 is obese and
  • 35 to 40 is severely obese

A Body Mass Index (BMI) that is higher than 40 is considered extremely obese, signifying that it carries a great risk to both immediate and long-term health problems.

How to calculate BMI

To calculate your BMI, divide your weight in pounds by the square of your height in inches (your height multiplied by itself) and multiply by 703.

Supposing, your height is 5 feet and 8 inches (5.8*12=69.6 inches)  tall and weight is 150 pounds.

Your BMI will be



Now multiply by 705

So, 0.0309*705= 21.7. In this case, your BMI is in the healthy range.
