Eosinophilic gastritis and gastroenteritis (EoG, EoGE): what it is, how it is treated and how we can help families in the Gulf

Reviewed by the Reserve Meds clinical operations team on 17 October 2026.

What are eosinophilic gastritis and gastroenteritis?

Eosinophilic gastritis (EoG) is a rare disease of the stomach in which a type of white blood cell, the eosinophil, gathers in large numbers and causes injury and irritation. Many patients with EoG also have eosinophilic disease in other parts of the gut, which is sometimes called eosinophilic gastroenteritis.^[1]

Symptoms include vomiting, nausea, trouble eating, stomach pain, poor growth or weight loss, anemia and tiredness. People with a personal or family history of allergic conditions may be at higher risk.^[1]

Diagnosis needs an endoscopy with biopsies, and there is no defined cut-off for how many eosinophils in the stomach are too high. There are no defined treatment guidelines; diet changes and medicines that reduce inflammation or calm the immune system, such as steroids, are used. Treatment lessens symptoms but does not cure it.^[1]

Eosinophilic gastritis and gastroenteritis in the Gulf

A case of eosinophilic gastroenteritis causing narrowing of the bulbo-duodenal junction was reported with medical and endoscopic management (2009), and Gulf pediatric specialists have described conditions that can mimic eosinophilic gut disease, such as gastrointestinal basidiobolomycosis (2021).^{[2, 3]}

Treatment and US-approved medicines

In our search of current US drug labels on 17 October 2026, we did not find a medicine whose US label lists eosinophilic gastritis or gastroenteritis as an approved use. Medicines used for it are chosen by the gastroenterologist. If your specialist prescribes a US-approved medicine for your case, we can help with access.^[1]

How families in the Gulf can access treatment

If it is not registered. The usual legal route is a named-patient request: the treating hospital, on your specialist's written request, asks the national regulator for permission to import the medicine for one patient, using the US FDA approval as the reference. In Saudi Arabia the SFDA Special Access Program guidance covers these requests; in Bahrain, NHRA Circular 41 of 2020 sets the procedure. Other Gulf countries have their own procedures, which the hospital confirms.^{[4, 5]} Once approval is in place, Reserve Meds arranges supply through a US-licensed pharmaceutical wholesale partner to the hospital.

Who does what

• Your treating specialist decides whether a medicine is right for the patient and writes the medical letter.
• The hospital checks local supply, files any import request, and gives the treatment safely.
• The national regulator decides whether to approve the import of a medicine that is not registered.
• The manufacturer decides where its medicine can be supplied, especially for cell and gene therapies.
• Reserve Meds helps organize records, coordinates US supply through our wholesale partner, shipping and updates to your family. We do not give medical advice.

Documents you will usually need

• A letter from the treating specialist with the diagnosis, past treatments and why this medicine is being considered
• Reports that confirm the diagnosis, such as genetic, pathology, imaging or laboratory results, translated into English where needed
• Recent clinic notes and a list of current medicines
• For a hospital import request: the prescription, the hospital's request form and the written consent of the patient or guardian
• Proof of the US FDA approval and the US prescribing information (we can supply these)

We give you a written timeline estimate for your case before you commit. The regulator, the hospital or treatment center and the manufacturer set their own timelines.

What treatment costs

Quote on request. Your total cost depends on the medicine, the dose, shipping, import steps and coordination. Your coordination fee is quoted in writing for your case before you commit. No hidden charges.
