Wesper LabFor Bariatric and Metabolic Care
Find sleep apnea before surgery and follow it after.
Obesity is a leading risk factor for obstructive sleep apnea. Wesper makes pre-operative testing and long-term follow-up simple, at home and on one patient record.
- FDA-Cleared
- Pre-Op and Follow-Up
- Multi-Night as Standard
Pre-Operative Testing
Direct respiratory data, at home.
Wesper Lab measures thoracic and abdominal effort, airflow, SpO2 and body position across multiple nights. That gives your team the full picture, including positional and hypoxia-dominant patterns, before surgery.
- Multi-night testing as standard
- Body position for positional analysis
- Oxygen saturation, ODI, hypoxic burden and T90
- Dropship to the patient's door
Long-Term Follow-Up
See how sleep apnea changes as weight changes.
Re-test after surgery or during medical weight management on the same patient record. Longitudinal trends show whether treatment is working, night over night and month over month.
- 45+ longitudinal trends on one record
- Wesper Lite for lower-burden follow-up
- Escalate to Wesper Lab without re-onboarding

From Clinicians
In their own words.
Obesity is the single greatest risk factor for OSA. Advances in treatment options like GLP-1 medications offer opportunity to reverse both obesity and OSA. With only 20% of people with OSA diagnosed, the greatest barrier to effective treatment is simply making the diagnosis. Wesper's HST program is a great solution to bridging this gap with cutting edge technology, ease of use, proven diagnostic accuracy, and comprehensive back-office support.
The physician portal on the Wesper platform is awesome! There is both granular as well as macroscopic data. The ability to see trends is a game-changer in sleep medicine.

Phenotypes, scoring and what they mean for pre-operative testing.
Which Wesper test is best before bariatric surgery?
Wesper Lab captures direct respiratory effort, airflow, SpO2 and body position across multiple nights, which suits pre-operative evaluation and complex cases.
Can we follow patients after surgery?
Yes. Repeat studies stay on the same patient record, so your team can track how sleep apnea changes as weight changes.
Do patients need to visit a sleep lab?
No. Wesper dropships the test to the patient's home and supports them through every night of testing.
