Esophagitis

The esophageal lining is thin and not designed for prolonged chemical or immune insult. When it is inflamed, swallowing can burn, food can catch, and eating becomes something to dread.

Reflux esophagitis is the most common form and follows the same mechanics as GERD. Eosinophilic esophagitis is an allergic and immune driven process, more common in younger patients and those with allergies or asthma. Pill esophagitis occurs when a tablet lodges and irritates the lining, often after taking medication with too little water or lying down soon after. Infectious esophagitis mostly affects people with impaired immunity.

• Reflux, by far the most common cause
• Eosinophilic esophagitis, an allergic and immune process
• Pill induced injury from tablets lodging in the esophagus
• Infection, usually in people with impaired immunity
• Radiation or caustic injury, uncommon

Acid suppression is the right treatment for reflux esophagitis and helps in some other cases, but it is not the answer to allergic disease, which needs dietary or immune directed treatment, nor to infection, which needs specific antimicrobial therapy.

Treating everything as reflux is the common error. Someone with eosinophilic esophagitis taking acid reducers for years, still catching food, is a recognizable pattern and a preventable one.

Endoscopy is central. The appearance of the lining suggests the cause, and biopsies confirm it. Biopsies are taken from multiple levels when allergic disease is suspected, because the findings can be patchy and a single sample can miss it.

Once esophagitis is confirmed as reflux related, pH testing and manometry help determine how much acid is reaching the esophagus and whether the muscular function is normal. That matters for planning anything beyond medication.

Reflux esophagitis is treated with acid suppression, and healing is usually confirmed on repeat endoscopy when the initial inflammation was significant. If it recurs promptly whenever medication stops, the barrier itself is the issue and that becomes the conversation.

Allergic esophagitis is managed with dietary elimination or targeted therapy, generally with an allergist and gastroenterologist. Pill esophagitis usually heals once the offending habit changes, with tablets taken upright and with plenty of water. Narrowing that has already formed can be dilated endoscopically.

Painful swallowing, food genuinely sticking, unintended loss of appetite, or any episode where food will not pass at all should be evaluated promptly rather than managed with over the counter remedies. Complete obstruction of the esophagus is an emergency.
