Understanding Trichobezoars: Causes, Symptoms, and Treatment Options

Trichobezoar (also known as a hairball or bezoar) is a mass of undigested hair that accumulates in the stomach or intestines, particularly in individuals who have a habit of swallowing their own hair. It is a relatively rare condition, but it can cause a range of symptoms, including abdominal pain, nausea, vomiting, and constipation.

Trichobezoars are most commonly found in children, especially those with trichotillomania (hair-pulling disorder), but they can also occur in adults. The exact cause of trichobezoar is not well understood, but it is thought to be related to the body's inability to digest hair properly.

There are several types of trichobezoars, including:

1. Gastric trichobezoar: This type of trichobezoar forms in the stomach and is the most common type.
2. Intestinal trichobezoar: This type of trichobezoar forms in the small intestine or large intestine.
3. Mixed trichobezoar: This type of trichobezoar involves both gastric and intestinal trichobezoars.

Trichobezoars can be diagnosed through a combination of physical examination, medical history, and imaging tests such as X-rays, CT scans, or endoscopy. Treatment for trichobezoar usually involves surgery to remove the hairball, but in some cases, medications may be prescribed to help break down the hair and facilitate its passage through the digestive system.
