Which of the following is a common symptom of gastroparesis?

Nausea and vomiting are hallmark symptoms of gastroparesis, which is a condition characterized by delayed gastric emptying. In gastroparesis, the stomach's ability to move food into the small intestine is impaired, leading to the accumulation of food in the stomach. This buildup can cause discomfort and trigger nausea. When food remains in the stomach longer than normal, it can also lead to vomiting due to the pressure and inability of the stomach to effectively manage its contents.

Other symptoms of gastroparesis can include early satiety (feeling full after eating only a small amount), bloating, and abdominal pain. Diarrhea is not typically associated with gastroparesis, as the condition slows the digestive process rather than speeding it up. Constipation can occur in some cases, but it is not as prominent as nausea and vomiting. Acid reflux may also be a symptom, but it is less definitive compared to the nausea and vomiting that patients with gastroparesis frequently experience. Therefore, the association of nausea and vomiting with disrupted gastric emptying makes it the most common symptom of gastroparesis.
