What is Diabetes?

Diabetes is a chronic condition where the body either does not produce enough insulin or does not use it effectively. Insulin is a hormone that helps glucose (sugar) find its way into the body’s cells to be used for energy. When someone has diabetes, the glucose stays in the blood instead of entering the cells, leading to high blood sugar levels. This can cause serious health problems, including blindness, kidney failure, heart problems, and nerve damage.

What is Obesity?

Obesity is a medical term used to describe an individual who is significantly overweight. It is usually determined by calculating a person’s body mass index (BMI), which is a measure of a person’s weight in relation to their height. A BMI of 30 or greater is considered obese. Being obese significantly increases a person’s risk for developing type 2 diabetes, as well as several other chronic conditions.

How Obesity Causes Diabetes

Obesity is a major risk factor for developing type 2 diabetes. In fact, it is estimated that up to 80 percent of people with type 2 diabetes are overweight or obese. There are several reasons why obesity increases the risk of diabetes. First, extra body fat can interfere with the body’s ability to use the hormone insulin to convert glucose into energy. This can lead to higher levels of glucose in the blood, which can develop into diabetes.


Another way obesity can cause diabetes is through inflammation. When a person is overweight or obese, the body is producing more inflammatory substances. This can lead to insulin resistance, which is when the cells become less sensitive to insulin. Over time, this can cause the body to produce less insulin and result in diabetes.


Genetics also plays a role in the relationship between obesity and diabetes. Some people may have a genetic predisposition to obesity and diabetes. This means that if one or both of their parents had type 2 diabetes, they are more likely to develop the condition themselves.

How to Prevent Diabetes

The best way to prevent diabetes is to maintain a healthy weight. This can be done by eating a balanced diet and exercising regularly. Eating a balanced diet means eating foods that are low in fat, sugar, and salt, and high in fiber and vitamins. Exercise should be done at least 30 minutes a day, five days a week. Additionally, it is important to get regular medical check-ups, as this can help detect diabetes early and allow for early treatment.


Obesity and diabetes are closely related, with obesity being one of the leading risk factors for developing type 2 diabetes. It is important to maintain a healthy weight in order to prevent diabetes, as well as other chronic conditions. Eating a balanced diet and exercising regularly can help keep weight in check and lower the risk of diabetes. Additionally, regular medical check-ups can help detect diabetes early, allowing for early treatment.
