You eat lots of sweets
Some research suggests sugar intake itself actually triggers diabetes — but eating too many sweets definitely causes weight gain, a major risk factor for the disease. “Approximately 90 per cent of type 2 diabetes patients are overweight or obese,” says Mohammad Kawji, MD, CCD, doctor of endocrinology and metabolism disorders at Spectrum Health. “Weight gain is associated with metabolic changes, mainly insulin resistance, which increases the risk to develop diabetes in the future.” As the pancreas has to secrete more insulin to balance blood sugar, it eventually fails, blood sugar rises, and diabetes develops. A simple blood test can test your blood sugar to see if it’s elevated. Unfortunately, Dr. Ng says that diabetes medications can also cause weight gain as they allow the body to absorb more sugar.
