Ingestion of paper?


Hello doctor, while I was sorting through some things and talking to a friend, I accidentally swallowed some torn paper scraps because I laughed at that moment.
I later tried to induce vomiting, but it was already swallowed and couldn't come back up.
Is there a risk that it could get stuck in my esophagus or trachea? I also feel a strange sensation in my throat afterward and can only drink more water for now.
Additionally, if it goes into my stomach, will it be digested and come out?

Hello! Since it is uncertain what size of paper you ingested, it is generally indigestible and can usually pass through the intestines.
Please monitor for any unusual symptoms such as coughing.
If you experience any, please consult a pulmonologist for evaluation.

Accidentally swallowing paper, especially small pieces, is generally not a cause for significant concern. However, there are some important considerations to keep in mind regarding the potential risks and outcomes of such an incident.

First, it’s essential to understand that paper is made primarily from cellulose, which is a complex carbohydrate that the human digestive system cannot break down. This means that while the paper will not be digested, it can still pass through the gastrointestinal tract. In most cases, small pieces of paper will move through the digestive system and be excreted without causing any harm. However, larger pieces or wads of paper could potentially pose a risk of obstruction, particularly if they are large enough to block the esophagus or intestines.

In your case, since you mentioned that you accidentally swallowed a small piece of paper while laughing, it is unlikely that it would cause a blockage in the esophagus or trachea (windpipe). The sensation of discomfort in your throat could be due to irritation from the paper or simply anxiety about the incident. Drinking water is a good idea, as it can help wash down any small particles and soothe your throat.

If the paper has made its way into your stomach, it will likely pass through your digestive system without any issues. However, it is important to monitor for any unusual symptoms. If you experience persistent pain, difficulty swallowing, vomiting, or any signs of gastrointestinal distress, it would be wise to seek medical attention. These symptoms could indicate a blockage or other complications that may require intervention.

In terms of the risk of the paper getting stuck in the esophagus or trachea, it’s important to note that the esophagus is a muscular tube that transports food from the mouth to the stomach. If a piece of paper were to become lodged, it could cause discomfort and difficulty swallowing. In rare cases, this could lead to more serious complications, such as perforation of the esophagus, which would require immediate medical attention.

As for the possibility of the paper being digested, it is important to clarify that while the paper itself cannot be digested, it will eventually pass through the digestive system and be excreted. The body’s digestive processes are designed to handle various non-digestible materials, and the gastrointestinal tract is quite resilient.

In summary, while swallowing a small piece of paper is generally not a cause for alarm, it is essential to remain vigilant for any unusual symptoms. If you experience any concerning signs, do not hesitate to consult a healthcare professional for further evaluation. It’s always better to err on the side of caution when it comes to your health.
