What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This completed observational study looked at how quickly food leaves the stomach (gastric emptying) in 163 people with simple obesity. Researchers used a special scan to measure stomach emptying time and checked how it relates to blood sugar and fat levels. The goal is to better understand the link between stomach function and metabolic problems like type 2 diabetes. No treatment was given; the study only analyzed existing medical data.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help doctors better understand how stomach emptying affects metabolism in obesity, potentially improving risk assessment and weight-loss strategies.
What could go wrong
This is an observational study, not a treatment trial. It only looks at existing data and does not test any new drug or intervention, so it cannot directly lead to a cure or therapy.

Inclusion Criteria: * Diagnostic criteria for obesity (BMI ≥ 28 kg/m²) and/or waist circumference ≥ 90 cm in adult males, ≥ 85 cm in adult females, or waist-to-hip ratio ≥ 0.9 in males and ≥ 0.85 in females; * Age 18-65 years; * Consent to undergo venous blood sampling and gastric emptying scintigraphy, with no contraindications to these procedures; * Consent to participate in this research project. Exclusion Criteria: * Diagnosed with secondary obesity, such as hypothyroidism, Cushing's syndrome, polycystic ovary syndrome, etc.; * Severe cardiovascular or cerebrovascular disease, rheumatic or immune-mediated disorders; * Severe metabolic disorders, such as diabetic ketoacidosis, hyperosmolar hyperglycaemic state, etc.; * Advanced malignant tumours; * History of medication known to affect glucose/lipid metabolism or gastric emptying rate, such as GLP-1 receptor agonists, glucocorticoids, antibiotics, anxiolytics or antidepressants; * Pregnancy or lactation; * Severe bleeding tendency or inability to undergo venous blood sampling; * Contraindications for gastric emptying scintigraphy, including pregnancy, lactation, severe gastrointestinal disorders such as acute gastrointestinal haemorrhage, intestinal obstruction or perforation, or allergy to components of the test meal; * Patients refusing gastric emptying scintigraphy, or refusal to sign the informed consent form; * Other circumstances deemed unsuitable for the study by the investigator.
