Hypothalamic Obesity Treatment Strategies Explored

Obesity; ePub 2018 Oct 8; Rose, Horne, et al

Stepwise treatment strategy for hypothalamic obesity (HyOb)—including nutritional, pharmacological, and surgical therapies in an experienced center—may be most valuable, according to a recent study. The International Registry of Hypothalamic Obesity Disorders (IRHOD) identified a large cohort with self-reported HyOb, a rare cause of rapid weight gain and early metabolic comorbidities. 87 participants were included for analysis (median age: 27 years, range: 3‐71 years). Researchers found:

  • A total of 96.5% had obesity, and 3.5% had overweight at maximal weight.
  • 75 had brain tumors (86%)—the majority were craniopharyngiomas (72% of those with tumors).
  • Non-tumor etiologies included congenital brain malformation (4.6%), traumatic brain injury (3.4%), and genetic anomaly (2.3%).
  • 90% received obesity treatments including nutritional counseling (82%), pharmacotherapy (59%), bariatric surgery (8%), and vagal nerve stimulation (1%).
  • 46% reported follow‐up BMI results after obesity treatment.
  • Surgery was most effective with lifestyle intervention and pharmacological therapy being less effective.
  • 80% of participants reporting follow‐up weight remained in the obesity range.
