A new study has found that obese individuals who are otherwise healthy can reduce their risk of developing diabetes by taking aspirin and aspirin-like compounds called salicylates as they can help increase the amount of insulin produced by the body.
Obesity is associated with insulin resistance, the first step toward type 2 diabetes.
Aspirin and other salicylates are known to reduce blood glucose in diabetic patients.
The latest research reveals a similar beneficial effect among obese individuals by increasing the amount of insulin secreted into the bloodstream.
"The administration of a salicylate led to the lowering of serum glucose concentrations," said Jose-Manuel Fernandez-Real of the Institut d'Investigacio Biomedica de Girona and CIBEROBN Fisiopatologia de la Obesidad, Spain, and lead author of the study.
"These findings highlight the importance of further research on the possible therapeutic benefit of aspirin in the fight against type 2 diabetes," they added.
In the study, the scientists evaluated the effects of triflusal (a derivative of salicylate) on 28 subjects (nine men and 29 women). The average age of the participants was 48 years old and their average Body Mass Index (BMI) was 33.9. A BMI of over 30 is considered obese.
During three, four-week treatment periods, the study participants received a 600 mg dose, a 900 mg dose, or a placebo once per day.
The researchers found that administration of triflusal led to decreased fasting serum glucose. Contrary to their expectations, insulin sensitivity did not significantly change during the trial. Insulin secretion, however, significantly increased in relation to the dose size.
In conjunction with the human studies, the researchers also conducted laboratory studies on insulin-producing cells (known as islets of Langerhans) from mice and humans.
he researchers observed that triflusal significantly increased the insulin secreted by these cells.
"Aspirin therapy has been recognized to improve glucose tolerance and to reduce insulin requirements in diabetic subjects. To our knowledge, this is the first study to show that salicylates lowered serum glucose in non-diabetic obese subjects. We believe that this effect was due to a previously unsuspected increase in insulin secretion rather than enhanced insulin sensitivity," said Fernandez-Real.
The study is published in the Journal of Clinical Endocrinology and Metabolism.
