Abdominal pain?


On the 17th, I accidentally swallowed a chicken bone while eating.
On the 18th, I felt a foreign body sensation in my throat, so I went to see an ENT specialist.
The doctor performed an endoscopy but did not find any bone inside.
Then, on the morning of the 19th, I suddenly experienced stomach pain, nausea, and diarrhea.
However, when I went to a large hospital for a check-up, the doctor said that the bone would not affect my gastrointestinal tract.
I would like to ask, is it really true that it won't have any impact?

Dr. Chen Qifeng reply Gastroenterology and Hepatology


Please undergo a gastroscopy examination.

More Info


Swallowed chicken bones can indeed cause stomach pain and other gastrointestinal symptoms, although the severity and type of symptoms can vary significantly from person to person. When a person accidentally swallows a chicken bone, several outcomes are possible, depending on the size, shape, and sharpness of the bone, as well as the individual's anatomy and health status.

First, it's important to understand that most small, smooth bones typically pass through the gastrointestinal tract without causing any issues. However, sharp or larger bones can pose a risk of injury to the esophagus, stomach, or intestines. If a bone becomes lodged in the esophagus, it can cause pain, discomfort, and a sensation of something being stuck. This can lead to symptoms such as difficulty swallowing, throat pain, or even aspiration if the bone enters the airway.

In your case, since you experienced throat discomfort and underwent an endoscopy that did not reveal any bone, it is likely that the bone either passed through your esophagus without causing harm or was small enough to go unnoticed. However, the subsequent onset of stomach pain, nausea, and diarrhea could be attributed to several factors:
1. Gastrointestinal Irritation: The act of swallowing a foreign object can sometimes irritate the gastrointestinal lining, leading to inflammation and discomfort. This irritation can manifest as stomach pain and nausea.

2. Psychological Factors: Anxiety and stress about having swallowed a bone can also lead to gastrointestinal symptoms. The mind-body connection is powerful, and worry can exacerbate physical symptoms.

3. Infection or Gastroenteritis: It's also possible that your symptoms are unrelated to the swallowed bone and could be due to a viral or bacterial infection, commonly known as gastroenteritis. This condition can cause stomach pain, nausea, vomiting, and diarrhea.

4. Food Intolerance or Reaction: If you consumed something that your body reacted to after swallowing the bone, this could also explain your symptoms.
Regarding the medical advice you received, it is generally true that a swallowed chicken bone does not typically cause long-term gastrointestinal issues if it passes through the digestive system without causing any obstruction or perforation. However, if you continue to experience significant pain, vomiting, or changes in bowel habits, it is crucial to seek further medical evaluation.
In some cases, imaging studies such as X-rays or CT scans may be warranted to rule out any complications, especially if there is a suspicion of perforation or obstruction.
In conclusion, while swallowed chicken bones can lead to stomach pain and other gastrointestinal symptoms, many factors can contribute to your current condition. It is essential to monitor your symptoms closely and consult with a healthcare provider if they persist or worsen. Always prioritize your health and seek medical attention when in doubt.
