Factors that increase ones chances or risks of suffering diabetes mellitus in the future include family history of diabetes, being overweight or obese, indulging in sedentary lifestyle, eating food rich in sugar, having hypertension, not exercising and (for a woman) delivering a baby weighing more than 4kg. One may have one or more of these risk factors and still not develop diabetes. There are three known facts in people that develop diabetes.
Firstly, the beta cells of the person’s pancreas produce insufficient insulin or produce no insulin at all. This could be from autoimmune diseases, drugs, infections, injuries, tumours etc causing damage to the pancreas. The resultant effect is absolute or relative insulin deficiency, and therefore diabetes mellitus.
The second known fact why someone may develop diabetes mellitus is failure of the target cells to respond as it should to insulin. The main target organs where insulin act include skeletal muscles, liver and fat cells. In this group of people, their pancreas produce adequate amount of insulin but the target cells are non responsive to the insulin. This is called insulin resistance and it’s a known fact causing diabetes mellitus.
Finally, degenerative changes involving the pancreas as a result of ageing or disease conditions is known to cause diabetes mellitus. It is known that with repeated injuries, insults, infections, inflammation etc to the pancreas over time, the beta cells of the pancreas will begin to function below expectations. One developing diabetes mellitus after 80 years of age could just be part of the ageing process involving all organs of the body.
However, diabetes mellitus is not due to demons, spiritual attacks, poison from enemies or due to any curse
With this knowledge, you are in a good position to educate the rest of us who still have lots of superstitions about diabetes mellitus.
