* Hair shedding: We all shed hair, and some of it can end up in our mouths, especially when brushing, eating, or talking.
* Hair chewing: Some people, particularly those with trichotillomania (a hair-pulling disorder), may chew or bite their hair, and some of it can be swallowed.
* Accidental ingestion: Hair can also be swallowed accidentally, for example, if it falls into food or drink.
What happens when you swallow hair?
Most of the time, swallowed hair passes through your digestive system without any issues. It's not digestible, so it's excreted in your stool. However, in some cases, hair can accumulate in the stomach, forming a hairball known as a trichobezoar.
Trichobezoars:
* Symptoms: Trichobezoars can cause abdominal pain, nausea, vomiting, and a feeling of fullness. In severe cases, they can block the digestive tract, requiring medical intervention.
* Causes: More common in people with trichotillomania or pica (a disorder where people crave non-food items).
* Treatment: Treatment for trichobezoars usually involves endoscopic removal or, in some cases, surgery.
Should you be worried about swallowing hair?
For most people, swallowing a few hairs occasionally is nothing to worry about. However, if you have a history of hair pulling or swallowing, or if you experience any of the symptoms listed above, it's important to see a doctor.
Prevention:
* Practice good hygiene: Brush your hair regularly to remove loose hairs.
* Be mindful of your hair: Be aware of your hair when eating or drinking.
* Seek professional help: If you have trichotillomania or pica, seek professional help from a therapist or counselor.
