## In brief

- A study from Ben-Gurion University of the Negev and Soroka University Medical Center proposes a biological mechanism for weight gain after successful obstructive sleep apnea treatment.
- The research was conducted on mice, according to the source.
- Many adults and children reportedly gain weight after successfully treating obstructive sleep apnea.

## Why it matters

It suggests that weight gain after apnea treatment may have a biological cause rather than only lifestyle factors, which could inform patient counseling and follow-up, although the findings come from animal research.
