Summary

This trial involves people who have low blood sugar after weight-loss surgery doing exercises without eating first. The study will see if their blood sugar drops and if their body responds correctly to this drop. The goal is to understand how exercise affects their glucose and hormone levels.

Who is the study for?
This trial is for adults aged 18-60 with post-bariatric hypoglycemia unresponsive to diet changes and acarbose therapy. Participants must be able to exercise, not have a history of certain medical conditions like active cancer (except some skin cancers), major recent surgery, or severe kidney disease, and agree to use contraception if applicable.
What is being tested?
The study tests how structured physical activity (like cycling or walking on a treadmill) affects blood sugar and hormone levels in fasting individuals with post-bariatric hypoglycemia. It aims to see if exercise induces low blood sugar and whether hormonal responses during exercise are different in these individuals.
What are the potential side effects?
Since the intervention involves physical activity, potential side effects may include typical exercise-related issues such as muscle soreness, fatigue, joint pain, or more serious events related to low blood sugar episodes triggered by exertion.

Other Research
Post-Bariatric Hypoglycemia (PBH) is often managed through structured exercise, which improves insulin sensitivity and enhances glucose uptake by muscles, helping to stabilize blood glucose levels. Exercise also modulates counterregulatory hormonal responses, which are typically impaired in PBH patients. This approach is significant as it offers a non-pharmacological method to reduce the frequency and severity of hypoglycemic episodes, improving overall patient outcomes.
