Gastrointestinal eosinophilic sclerosing fibroplasia (FGESF) is a rare disease that affects pets. It's also often referred to as idiopathic megaesophagus, or ME for short.

FGESF is a type of ME that causes inflammation and enlargement of the esophagus and surrounding tissue due to an abnormal immune response in white blood cells called eosinophils. This condition can be life-threatening for affected pets if not promptly treated by veterinarians who are experienced with this type of disease.

What Is FGESF?

FGESF, sometimes called feline idiopathic intestinal fibrosis or "inflammatory bowel disease," is a gastrointestinal tract disease (the organ system that digests food in cats). It is caused by an immune system response to a protein in the body. This protein is present in all healthy animals but may cause an immune reaction in some cats. FGESF can affect any age or breed of cat, but it is more common in young adult male cats. This disease is not contagious.

How Do I Know If My Pet Has It?

The signs of FGESF typically include fever, often with a low-grade temperature (less than 101 degrees F) for weeks or months. Your pet may have more than one symptom at once. For example, he could be vomiting and have diarrhea. Or he could have anemia along with fever. Or maybe his liver is failing because of the disease instead of from something else entirely. It depends on what part of his body is affected by FGESF first and what other organs are affected after that.

How Is It Diagnosed?

When you go to the vet for a check-up, your veterinarian will perform several tests. Bloodwork, biopsies, and urinalysis are all used to diagnose FGESF. X-rays can also be performed to look for other health issues that could be making your cat's symptoms worse.

If the results of these tests come back positive, then it is likely that your cat has FGESF. Once diagnosed with this condition, there are treatment options like antibiotics for cats that may help improve their quality of life and reduce pain or discomfort using pet medications like prednisolone for cats as they experience symptoms associated with this disease.

What Will Happen After The Biopsy?

After you bring your pet to the vet, they will perform a biopsy on their stomach. The vet will send the biopsy sample off to a pathologist who specializes in analyzing tissue samples. The pathologist will review the results of your pet's biopsy and determine if they have FGESF or some other condition.

After this process happens, your vet will discuss the results with you. They'll recommend treatment and pet medicines based on what's best for your cat.

What Can I Do To Help My Pet?

As an owner, you play a vital role in helping your pet deal with FGESF. You can help by:

  • Monitoring their condition and activities. Keep track of how much weight they've lost and whether or not they're eating normally. If you notice any changes, consult your vet right away and opt for a Purina pro plan sensitive stomach diet.

  • Helping them cope with stressors. Suppose it seems like your pet is stressed out by something. In that case, try to figure out what’s causing that stress and remove it from the equation as much as possible. This will take some time but will ultimately be beneficial in the long run.

  • Establishing regular exercise routines for yourself and your pet, even once or twice per week for 10 minutes at a time, can make all the difference. When exercising together, be mindful about where you walk (if there are many bugs here, then maybe go somewhere else instead). Keep the cat harness and leash snapped tightly on securely so he won't get away if you let loose accidentally while trying something new(for example, skateboarding). Letting go of fear doesn't always happen overnight but keep trying anyway.


We know that this can be a scary diagnosis for any pet owner, but there is hope. With the right medical care and monitoring of your cat’s condition, you can help them live a long, happy life. We want to make sure that you and your feline friend have all the information available so that you can make an informed decision about treatment and pet meds options.
