Ali et al developed the Assessment of Obesity-Related Comorbidities Scale (AORC) to evaluate a morbidly obese patient undergoing bariatric surgery. This can be used to evaluate the patient before and after surgery. The authors are from the University of California at Davis in Sacramento, California.


NOTE: I modified the scale slightly by adding erectile dysfunction for males to balance polycystic ovary syndrome in females in the spreadsheet.


Comorbid conditions:

(1) back pain (musculoskeletal)

(2) joint disease (musculoskeletal)

(3) gastroesophageal reflux disease (GERD)

(4) pseudotumor cerebri

(5) stress urinary incontinence

(6) ventral/umbilical hernia

(7) diabetes mellitus

(8) hypertension

(9) dyslipidemia

(10) cholelithiasis

(11) polycystic ovary disease in women (add erectile dysfunction for males)

(12) sleep apnea syndrome

(13) lower extremity edema

(14) psychosocial impairment

(15) depression

(16) obesity hyperventilation syndrome

(17) pulmonary hypertension


Each item is graded from absent (0 points) to severe (5 points).


overall score =

= SUM(points for all 17 comorbid conditions)



• minimum overall score: 0

• maximum overall score: 85

• The score after surgery for each comorbidity can be compared to the pretreatment level. Ideally the postoperative score is significantly less than the preoperative score.

• An increasing score may indicate therapeutic failure.
