Which of the following symptoms is commonly associated with swallowing a foreign body?

Swallowing a foreign body can lead to several gastrointestinal symptoms, but regurgitation is particularly associated with this event due to the obstruction or irritation that the foreign object may cause in the esophagus or surrounding areas. When a foreign body becomes lodged in the esophagus, it can lead to a partial or complete blockage. As a result, food and liquids can back up, leading to regurgitation, which is the act of bringing swallowed food or liquid back up to the throat or mouth.

In contrast, constipation and diarrhea are less directly related to the immediate effects of foreign body ingestion. While a foreign body could eventually influence bowel movements depending on its size and location within the gastrointestinal tract, these symptoms are not as directly tied to the act of swallowing as regurgitation is. Similarly, fatigue is a nonspecific symptom that could arise from many conditions but is not typically associated with the acute effects of swallowing a foreign body. Thus, regurgitation stands out as the most relevant symptom in the context of this scenario.
