Overweight and Diabetes

 Obesity/  overweight  is believed to account for 90% of the risk of developing type 2 diabetes, while recent research suggests that obese people are up to 90 times more likely to develop type 2 diabetes than those with a BMI more than 25 .
According To world Health organization at present  422 million people worldwide have Diabetes, particularly in low and middle income countries,
and 1.6 million deaths are attributed to Diabeties each year.

                                      Diabetes is a group of disorders characterized by chronic high blood glucose levels (hyperglycemia) due to the body's failure to produce any or enough insulin to regulate high glucose levels.
The hormone insulin moves sugar from the blood into your cells to be stored or used for energy. With diabetes, your body either doesn’t make enough insulin or can’t effectively use the insulin it does make.

There are two main types of diabetes:

 Type 1 diabetes :which often occurs in children or adolescents, is caused by the body's inability to make insulin .

 Type 2 diabetes :which occurs as a result of the body's inability to react properly to insulin (insulin resistance). Type 2 diabetes is more prevalent than type 1 diabetes and is therefore seen in roughly 90% of all diabetes cases.
Type 2 diabetes is predominantly diagnosed after the age of forty, however, it is now being found in all age ranges, including children and adolescents.

Gestational  Diabetes:  During pregnancy, some women develop high blood sugar levels. This condition is known as gestational diabetes mellitus .

Prediabeticwhen your blood sugar is higher than normal, but it’s not high enough for a diagnosis of type 2 diabetes.

Symptoms of Diabetes:

Complications of Diabetes:

The impact of diabetes goes beyond chronic hyperglycemia. Diabetes is the leading cause of blindness (diabetic retinopathy), cataracts, glaucoma,end stage kidney diseases (diabetic nephropathy) and non-traumatic lower extremity amputations (diabetic neuropathy) ,diabetic foot,in working-age adults. People with diabetes are also two to four times more likely to experience cardiovascular complications and strokes.people with diabetes  may have a higher risk of developing severe medical complications, such as pneumonia  from  COVID-19. 


There are many risk factors for type 2 diabetes such as age, race, pregnancy, stress, certain medications, genetics or family history, high cholesterol and obesity. However, the single best predictor of type 2 diabetes is overweight or obesity. Almost 90% of people living with type 2 diabetes are overweight or have obesity. People who are overweight or have obesity have added pressure on their body's ability to use insulin to properly control blood sugar levels, and are therefore more likely to develop diabetes.

What can you do to prevent diabetes?

Type 2 diabetes is largely preventable. Studies have found that lifestyle changes and small amounts of weight loss in the range of 5-10% can prevent or delay the development of type 2 diabetes among high-risk adults. Lifestyle interventions including diet and moderate to intense physical activity  help small amounts of weight loss.
