Which symptom is typically associated with gastroparesis?

Gastroparesis is a condition characterized by delayed gastric emptying, which can lead to a variety of symptoms primarily related to digestion. Abdominal pain is a common symptom associated with this condition due to the buildup of food in the stomach, which can cause distension and discomfort. Patients often experience prolonged fullness after meals, nausea, and sometimes vomiting, which can contribute to overall abdominal pain.

The other options present symptoms that are not typically associated with gastroparesis. Severe constipation is more related to issues with bowel motility rather than gastric emptying. Diarrhea generally suggests rapid gastric emptying or malabsorption, which is the opposite of what occurs in gastroparesis. Weight gain may occur due to slowed gastric emptying leading to increased caloric absorption over time, but it is not a direct symptom of the condition. Thus, abdominal pain is the most relevant symptom in the context of gastroparesis.
