The number of people in the UK with type 2 diabetes has tripled from 700,000 to 2.8 million over the last 20 years in a study reported by students at Cardiff University. The research also shows an increase in life expectancy for those with the disease. Between 1993 and 2010 the proportion of obese people across the UK doubled from 13% to 26% for men and 16% to 26% for women. Rates of the type 2 form of the disease are on a continual rise, according to a Professor at Cardiff’s school of medicine. The increased life expectancy finding could be due to earlier diagnoses of the condition as well as an increase usage of blood pressure tablets. The research also revealed that prevalence of type 2 diabetes tends to increase with age. Type 2 diabetes can be treated with a healthy diet, increased physical activity, and increased insulin production, which is triggered by the GLP-1 hormone.
