What happens when you swallow a hair: Understanding hair ingestion

Swallowing a hair might sound alarming, but it happens more often than you think. Hair strands can accidentally enter your mouth while eating, chewing, or even biting your own hair. Most of the time, swallowing hair is completely harmless, and your digestive system is capable of passing it through without causing any health issues. Hair is made of keratin, a strong protein that cannot be digested by stomach enzymes.According to research published in Gastroenterology Reports, hair strands that accumulate in the stomach over time can rarely form a trichobezoar, a mass that may lead to discomfort or digestive problems. While this is uncommon, it highlights why repeated hair ingestion or habits like chewing hair can pose health concerns.In this article, we explore what happens when you swallow a hair, the potential risks, and when you should consult a healthcare professional. Understanding the science behind hair ingestion can put your mind at ease and help you take precautions for a healthy digestive system.Hair is made of keratin, a resilient protein that your body cannot digest. When a hair strand is swallowed, it travels through the digestive system largely intact. In most cases, it passes through the stomach and intestines without causing harm, exiting the body naturally.The digestive system is well-equipped to handle small, indigestible materials like hair, and only in rare cases does hair accumulation lead to complications.Although rare, repeated hair ingestion can result in the formation of a trichobezoar. This is a compact mass of hair that can accumulate in the stomach over time, causing nausea, vomiting, abdominal pain, or digestive blockage. Trichobezoars are more commonly reported in individuals with trichophagia, a condition in which people habitually eat hair.While most swallowed hairs pass without issue, awareness of this potential risk is important, especially for those with repetitive hair-chewing habits.Most hair ingestion incidents do not require medical intervention. However, if you experience persistent abdominal discomfort, nausea, vomiting, or signs of digestive obstruction, it is important to consult a healthcare professional.Medical imaging can identify trichobezoars or other complications, and in severe cases, surgical removal may be necessary. Early consultation can prevent more serious gastrointestinal issues.Reducing hair ingestion is simple with mindful habits. Avoid chewing hair, keep long hair tied back while eating, and be cautious with loose hair strands around food preparation areas. For those with trichophagia, behavioural therapy or counselling may help curb habitual hair ingestion.Maintaining a clean environment and being aware of potential hair exposure can significantly reduce the risk of swallowing hair.Swallowing a hair is generally harmless, and the digestive system is capable of passing it naturally. However, repeated hair ingestion can lead to the rare formation of trichobezoars, which may require medical attention.Understanding how hair interacts with the digestive system, recognising potential risks, and taking simple precautions can keep you safe. While most swallowed hairs are nothing to worry about, staying informed ensures your digestive health remains intact.Disclaimer: This article is for general informational purposes only and is not a substitute for professional medical advice, diagnosis, or treatment.
