Why Presence Of A Comorbidity May Not Be Enough To Decide Who Will Benefit From Bariatric Surgery
Thursday, June 11, 2015Irrespective of the fact that bariatric surgery has now become so safe (at high-volume centres) that it compares well with other common surgical procedures like having your gall bladder removed, it is still surgery.
As even the safest surgery carries risk, it should never be taken lightly and thus the question of whether or not people with obesity but no related comorbidities stand to benefit from bariatric surgery is an important question.
One of the key outcomes (at least for patients) is the impact on quality of life which is why Hilde Risstad and colleagues from the University of Oslo, studied the effect of bariatric surgery on patients presenting with obesity related comorbidities and those without, published in Obesity Surgery.
They studied 232 patients with severe obesity before and 2 years after Roux-en-Y gastric bypass.
Obesity related disease was defined as having at least one of the following conditions: type 2 diabetes mellitus, hypertension, dyslipidemia, coronary heart disease, obstructive sleep apnea, gastroesophageal reflux disease, or osteoarthritis.
Not only was baseline quality of life similar in patients with and without obesity-related disease prior to gastric bypass but it also improved equally in both groups.
This may not be entirely surprising.
Readers may recall that the Edmonton Obesity Staging System (EOSS), specifically designed to asses obesity related health risks, does not just consider medical comorbidities (as in this study) – EOSS gives as much importance to mental and functional health (not assessed in this study).
Thus, it is not surprising, that even without the presence of an obesity related medical complications like diabetes or sleep apnea, health (and thus quality of life) can be significantly affected by mental health and/or functional status, both of which can markedly improve after bariatric surgery.
This is why, pre-assessment or triaging patients for bariatric surgery should not only consider medical problems but also mental and functional health – as in EOSS.
