Oesophagus Problems for Bulimics

How bulimia affects the oesophagus

Bulimia involves cycles of eating large quantities of food in a short period, followed by purging through vomiting or laxative use. These episodes often happen several times a week and can continue for months or years.

The oesophagus, the tube connecting your throat to your stomach, bears much of the physical damage from repeated vomiting. Stomach acid is highly corrosive and was never meant to travel upwards through this delicate tissue. Over time, the effects can range from mild discomfort to serious medical emergencies.

Throat irritation and soreness

A persistent sore throat is one of the most common physical signs of bulimia. Each time someone vomits, stomach acid passes through the oesophagus and throat, stripping away the protective lining. This causes raw, inflamed tissue that may feel constantly tender.

The irritation can spread to the mouth and soft palate. Some people notice their throat or face looks slightly puffy, particularly around the jaw. This swelling may worsen if an infection develops in the damaged tissue.

Swallowing can become painful, which sometimes leads to avoiding food and drink. This creates a further risk of dehydration, especially if purging has already depleted the body's fluids and electrolytes.

Because many people with bulimia purge privately, these symptoms may go unnoticed by others for a long time. A GP or dentist may be the first to spot the signs during a routine appointment.

Ulcers and more serious damage

When acid exposure continues over weeks or months, the irritation can develop into ulcers. These are open sores in the oesophageal lining that may bleed and cause significant pain, particularly when eating or drinking.

Repeated damage weakens the tissue and can lead to a condition called oesophagitis, where chronic inflammation prevents proper healing. Scarring may narrow the oesophagus over time, making swallowing difficult even after the purging stops.

In severe cases, the oesophagus can tear. A small tear, known as a Mallory Weiss tear, typically occurs at the junction between the oesophagus and stomach. This causes vomiting blood and requires medical attention. A full rupture, though rare, is a medical emergency that can be fatal without immediate surgery.

Barrett's oesophagus, a condition where the cell lining changes due to prolonged acid exposure, is another possible complication. This increases the long term risk of oesophageal cancer and requires ongoing monitoring.

Getting support

The physical effects of bulimia on the oesophagus will usually improve once purging stops, though some damage may take time to heal. Early treatment gives the body the best chance of full recovery.

Your GP can assess any oesophageal symptoms and refer you for further tests if needed. They can also connect you with eating disorder services in your area. You do not need to wait until symptoms become severe before seeking help.

Beat, the UK's eating disorder charity, offers helplines, online support groups and information for anyone affected by an eating disorder. Their services are free and confidential. The NHS website also provides guidance on treatment options and what to expect from specialist services.

If you are supporting someone else, Beat has resources specifically for families and carers. Recovery from bulimia is possible, and addressing the physical damage is often part of a wider treatment plan that includes psychological support.
