Gastroparesis is a condition in which the stomach takes too long to empty its contents, causing nausea, vomiting, bloating, and abdominal pain. It affects ~5 million Americans, with women being four times more likely to be affected than men. Diabetes is the most common identifiable cause, responsible for ~33% of cases, while ~36% of cases are idiopathic (no identifiable cause). Other causes include post-surgical complications, neurological conditions, and certain medications. Gastroparesis can significantly impact nutrition, blood sugar control, and quality of life. The chronic, debilitating nature of the condition and limited treatment options drive extensive online searching for information and management strategies.
The Question We Asked
“I’ve had nausea, bloating, and feeling full after eating only small amounts for about six months. I sometimes vomit undigested food hours after eating. I’ve lost about 10 pounds because I can’t eat much. I’m 45 with type 2 diabetes. My doctor ordered a gastric emptying study. Could this be gastroparesis? What are the treatment options?”

What Each Model Got Right
GPT-4
Strengths: GPT-4 correctly identified the symptom pattern as highly suggestive of gastroparesis, particularly in the context of diabetes. It explained the gastric emptying study (scintigraphy) as the diagnostic gold standard and provided a good overview of management including dietary modifications (small, frequent, low-fat, low-fiber meals), prokinetic medications (metoclopramide), and blood sugar optimization.
Claude 3.5
Strengths: Claude delivered the most comprehensive response, correctly linking diabetic autonomic neuropathy to gastroparesis and explaining how poor gastric emptying creates a vicious cycle with blood sugar control. It provided the most detailed dietary guidance (liquid or pureed foods during flares, small frequent meals, avoiding high-fat and high-fiber foods), discussed medications (metoclopramide, domperidone, erythromycin), and mentioned advanced therapies including gastric electrical stimulation and pyloromyotomy. It also addressed nutritional supplementation concerns.
Gemini
Strengths: Gemini offered practical mealtime tips including eating slowly, chewing thoroughly, walking after meals, and avoiding carbonated beverages. It correctly noted that lying down after eating should be avoided and suggested positioning strategies.
Med-PaLM 2
Strengths: Med-PaLM 2 provided detailed clinical information about the gastric emptying study protocol, the relationship between glycemic control and gastric motility, and the full spectrum of treatment options from dietary modification through pharmacological and interventional therapies. It discussed the newer option of per-oral pyloromyotomy (G-POEM) as an emerging treatment.
What Each Model Got Wrong or Missed
GPT-4
- Did not discuss the blood sugar management connection in sufficient detail
- Failed to mention the potential for nutritional deficiencies and need for supplementation
- Could have discussed anti-nausea medications more specifically
Claude 3.5
- Did not mention the importance of hydration strategies alongside dietary modifications
- Could have discussed the emotional and psychological impact of chronic nausea and restricted eating
Gemini
- Did not discuss the diabetic connection or the blood sugar management aspect
- Oversimplified treatment by focusing mainly on dietary tips
- Failed to mention prokinetic medications or anti-emetics
Med-PaLM 2
- Too clinical for someone struggling with chronic nausea and weight loss
- Did not provide practical daily dietary guidance
- Failed to address the quality-of-life impact and emotional burden
Red Flags All Models Should Mention
Gastroparesis can lead to serious complications requiring medical attention:
- Persistent vomiting preventing any food or fluid intake — risk of dehydration and malnutrition requiring hospitalization
- Significant weight loss (more than 5-10% of body weight) — nutritional intervention may be needed
- Bezoar formation (hardened mass of undigested food) — can cause obstruction
- Severe blood sugar instability in diabetic patients — gastroparesis makes glycemic control unpredictable
- Signs of dehydration (dark urine, dizziness, rapid heartbeat) — may need IV fluids
- Vomiting blood or severe abdominal pain — may indicate complications requiring emergency evaluation
When to Trust AI vs. See a Doctor
AI Is Reasonably Helpful For:
- Understanding what gastroparesis is and its connection to diabetes
- Learning about dietary modifications for delayed gastric emptying
- Getting practical mealtime and eating strategies
- Understanding what the gastric emptying study involves
- Learning about the range of treatment options available
See a Doctor When:
- You have symptoms suggestive of gastroparesis (diagnostic testing needed)
- You are losing weight or unable to maintain adequate nutrition
- You need medication for nausea or to improve gastric motility
- Your blood sugar control has worsened alongside GI symptoms
- You are unable to keep food or fluids down for more than 24 hours
- You need nutritional counseling or supplementation
- Current treatments are not providing adequate symptom relief
Methodology
Each AI model received the identical patient scenario prompt. Responses were evaluated by the mdtalks editorial team using our standardized evaluation framework, which assesses factual accuracy against current gastroenterology and diabetes guidelines, completeness of safety warnings, readability for a general audience, and appropriateness of the recommendation to seek professional care. Scores reflect composite ratings across these dimensions.
Key Takeaways
- Claude 3.5 scored highest (9.0) for its comprehensive discussion of the diabetes-gastroparesis connection and detailed dietary guidance
- Gastroparesis in diabetic patients creates a challenging cycle of poor gastric emptying and unstable blood sugars
- Dietary modification is the cornerstone of management, with small, frequent, low-fat, low-fiber meals
- Weight loss and nutritional deficiency are serious concerns that may require medical nutritional support
- Gemini scored lowest (7.2) due to oversimplified treatment discussion and insufficient diabetes connection
