Type 2 Diabetes

Type 2 Diabetes

Bariatric surgery has long been associated with improvements in type 2 diabetes control.  At first this effect was thought to be down to the beneficial effect of post-op weight loss.  However, recent studies have shown that surgery also directly affects how the body controls blood sugar by changing the levels of special hormones made by the intestine.

The most effective operations that help type 2 diabetes (in order of effectiveness) are the one anastomosis gastric bypass; the Roux-en-Y gastric bypass and the sleeve gastrectomy.

Surgery for type 2 diabetes is not necessarily a permanent cure, but for the majority of patients it offers the chance to reduce or even completely stop diabetes drugs (including insulin and non-insulin injections).

New 2022 guidelines state that bariatric surgery should be recommended to you as a treatment for your diabetes if you have:

  • a BMI over 30 (regardless of how well-controlled your diabetes is)
  • If you living with diabetes and are of Asian or Afro-Caribbean origin, the advice is to offer surgery at a BMI of 27.5 or higher.
