• Prior gastric surgery including total or subtotal (near complete) gastric resection, esophagectomy, gastrojejunostomy, gastric bypass, gastric sleeve, pyloroplasty, pyloromyotomy, or any fundoplication (Nissen, Tor)
• Females who are pregnant. A urine pregnancy test is routinely obtained on all females immediately prior to gastric emptying procedures.

Other illness

• Presence of other conditions that could explain the patient's symptoms such as:
• Active inflammatory bowel disease
• Primary neurological conditions that can cause nausea and vomiting such as increased intracranial pressure, space occupying or inflammatory/infectious lesions
• Acute liver failure or advanced liver disease (Child's B or C; a Child-Pugh-Turcotte (CPT) score of ≥7)
• Pancreatic disorder if present on pancreatic imaging or pancreatic function testing
• Any other condition, which in the opinion of the investigator, could explain the symptoms or interfere with study requirements
• Inability to comply with or complete the gastric emptying scintigraphy test (including allergy to eggs)

Lab values

• Acute or chronic renal failure (serum creatinine \>3 mg/dL) and/or on hemodialysis or peritoneal dialysis

Other
