If hair accidentally goes into your stomach, it typically passes through your digestive system without causing harm. However, in rare cases, a large amount of ingested hair can form a bezoar, a solid mass that may require medical intervention.
What Happens When You Swallow Hair?
Swallowing a small amount of hair is a surprisingly common occurrence, especially for children and individuals with long hair. For most people, this ingested hair will simply travel through the digestive tract and be eliminated from the body along with other waste. The stomach’s acidic environment and the natural churning action of the intestines usually break down or move along small foreign objects.
The Digestive Journey of Ingested Hair
Once swallowed, hair enters the stomach. The stomach acid, primarily hydrochloric acid, is quite potent and can begin to break down organic materials. While hair is primarily made of keratin, a tough protein, it’s not completely impervious to digestion.
The churned contents then move into the small intestine. Here, further digestive enzymes and muscular contractions continue the process of breaking down food and moving it along. Eventually, the indigestible parts, including most swallowed hair, reach the large intestine.
In the large intestine, water is absorbed, and waste material is formed. The hair, if it hasn’t already passed, will be incorporated into the stool and eventually expelled from the body. This process is usually uneventful.
When Does Swallowed Hair Become a Problem?
While rare, there are situations where swallowing hair can lead to complications. This typically involves the ingestion of large quantities of hair over an extended period. This is more common in individuals with trichophagia, a compulsive disorder characterized by the urge to eat hair.
In such cases, the hair can accumulate in the stomach or intestines, forming a trichobezoar. A bezoar is a mass of undigested material that can obstruct the digestive tract. These masses are not easily broken down by digestive processes.
Understanding Bezoars and Their Risks
A trichobezoar is a specific type of bezoar formed from hair. These are more frequently seen in children and young adults, particularly females, who may engage in hair-pulling and eating behaviors.
Symptoms of a Hair Bezoar
The symptoms of a hair bezoar can vary depending on its size and location. Smaller bezoars may cause no noticeable symptoms at all. However, larger ones can lead to:
- Abdominal pain: Often felt in the upper abdomen.
- Nausea and vomiting: Especially after eating.
- Loss of appetite: Leading to unintended weight loss.
- Feeling of fullness: Even after consuming small amounts of food.
- Constipation: Due to the obstruction.
- In severe cases: Perforation of the stomach or intestine.
Diagnosing and Treating Hair Bezoars
If a hair bezoar is suspected, a doctor will likely perform a physical examination and may order imaging tests. These can include X-rays, CT scans, or endoscopy to visualize the mass.
Treatment depends on the size and severity of the bezoar. Small bezoars might be managed with dietary changes or medications to help break them down. However, larger or obstructive bezoars often require surgical removal. This is a significant procedure that addresses the immediate blockage and allows for examination of the digestive tract.
Preventing Accidental Hair Ingestion
For most people, accidental hair ingestion is not a concern. However, for those who are prone to swallowing hair, or in situations where it might be more likely (like cooking for others), some simple precautions can be taken.
- Tie back long hair: Especially when cooking or handling food.
- Be mindful of children: Supervise them closely to prevent them from eating non-food items.
- Seek professional help: If you or someone you know experiences compulsive hair-eating, seeking psychological support is crucial. Therapies like Cognitive Behavioral Therapy (CBT) can be very effective.
People Also Ask
### Can swallowing hair make you sick?
Swallowing a small amount of hair is generally not harmful and will pass through your system. However, if a large mass of hair forms a bezoar, it can cause digestive issues like pain, nausea, and vomiting, requiring medical attention.
### How long does it take for swallowed hair to pass?
Typically, swallowed hair will pass through the digestive system within a few days, similar to other indigestible materials. If it forms a bezoar, it will not pass on its own and may require medical intervention.
### Is it bad to swallow your own hair?
Swallowing a few strands of your own hair is usually not a problem. Your digestive system is designed to handle small amounts of indigestible material. Problems arise only if large quantities are ingested repeatedly, potentially forming a bezoar.
### What happens if a dog eats hair?
Similar to humans, small amounts of ingested hair are unlikely to harm a dog and will pass through their system. However, large amounts, especially from grooming or eating hairballs, can lead to gastrointestinal blockages or bezoars, requiring veterinary care.
Conclusion: Hair in the Stomach – Usually No Cause for Alarm
In summary, if hair accidentally enters your stomach, it will most likely pass through your digestive system without any ill effects. The digestive process is robust enough to handle small amounts of such material. The primary concern arises only in rare instances of significant, chronic ingestion leading to the formation of a hair bezoar, which necessitates medical intervention. Maintaining awareness and seeking help for compulsive behaviors are key to preventing potential complications.
If you are concerned about hair ingestion or experiencing related symptoms, it is always best to consult with a healthcare professional.
