Perioperative exercise and breathing therapy for people having bariatric surgery

Impact of a Perioperative Physical Exercise and Respiratory Physiotherapy Program on the Patient Undergoing Bariatric Surgery

Not applicable Interventional Fundacin Biomedica Galicia Sur · NCT06987903

This program will test whether supervised exercise and respiratory physiotherapy before and after bariatric surgery helps adults recover faster, have fewer complications, and leave the hospital sooner.

What this trial studies

Adults scheduled for elective bariatric surgery at Hospital Álvaro Cunqueiro will be offered a pre- and post-operative supervised physical exercise program combined with respiratory physiotherapy. Clinical outcomes such as postoperative complications, adverse events, and length of hospital stay will be tracked alongside tissue and non‑invasive samples (fat, muscle, blood, saliva) to study epigenetic changes and liver tissue effects. The study will compare clinical recovery and molecular markers to see whether prehabilitation correlates with better surgical outcomes and liver disease evolution. Exclusions include urgent or combined surgeries, inability to consent, illiteracy or dependence on a legal representative, and unstable GLP‑1/SGLT2 therapy.

Who should consider this trial

Good fit: Adults aged 18–69 scheduled for elective bariatric surgery at the General and Digestive Surgery Department of Álvaro Cunqueiro Hospital who can give informed consent and meet the inclusion/exclusion criteria.

Not a fit: Patients needing urgent or combined surgeries, those who cannot participate in the exercise or physiotherapy program, those unable to consent, or patients on unstable GLP‑1/SGLT2 regimens are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the program could lower surgical risks, reduce postoperative complications, and shorten hospital stays for patients having bariatric surgery.

How similar studies have performed: Prehabilitation and respiratory physiotherapy have reduced pulmonary complications and improved recovery in other surgical populations, and some bariatric-specific studies suggest benefit though results are variable.
