What is it?

Triaditis refers to the simultaneous inflammation of three neighboring organs in cats: the bile ducts of the liver, the pancreas and the small intestine.

This association is not a coincidence. In cats, the pancreatic duct and the bile duct join before entering the intestine. Inflammation in one place easily spreads to the other two.

It is therefore not one more disease, but the observation that three chronic diseases of cats, cholangitis, pancreatitis and inflammatory bowel disease, often coexist in the same animal.

Commonly observed signs

These signs are neither exhaustive nor specific. Only a veterinarian can establish a diagnosis.

Related signs — each one links to its page:

Loss of appetite Weight loss Vomiting Diarrhea Reduction Jaundice Dehydration Fatigue

The signs are those of the three diseases mixed together, and they vary greatly from one cat to another.

Loss of appetite, sometimes fluctuating: the cat eats then sulks for several days.

Progressive weight loss despite an unchanged ration.

Intermittent vomiting and chronic diarrhea, alternating or separately.

Dejection, prickly hair, cat that washes less.

Jaundice when the hepatic component dominates.

Discreet abdominal pain, often only betrayed by a cat who no longer likes to be carried.

A sawtooth evolution, with periods of apparent improvement, is very evocative.

When to consult without delay

This list does not replace veterinary advice. It gathers situations that justify a prompt consultation.

Causes and risk factors

The particular anatomy of the cat, which communicates the bile duct and the pancreatic duct just before the intestine, favors the spread of inflammation from one organ to another.

A rise of bacteria from the intestine towards the bile ducts is one of the accepted mechanisms.

A disruption of the immune system of the intestinal wall maintains long-term inflammation.

Imbalances in the intestinal flora and food intolerances contribute to the maintenance of the phenomenon.

In many cases, it is not known which organ was affected first.

Middle-aged to elderly cats.

Known history of inflammatory bowel disease, pancreatitis or cholangitis: the presence of one of the three should prompt the search for the others.

No breed predisposition has been firmly demonstrated.

Diagnosis and care

Diagnosis is the veterinarian's responsibility, based on clinical examination and laboratory tests. Care is decided case by case.

The diagnosis requires exploring all three organs rather than just one.

A complete blood test evaluates the liver, pancreas, kidneys, and dose markers of intestinal absorption and certain vitamins.

An abdominal ultrasound simultaneously examines the liver, bile ducts, pancreas and the thickness of the intestinal wall.

Samples from the liver and intestinal wall, taken by puncture, endoscopy or surgery, provide the most reliable diagnosis and make it possible to distinguish inflammation from digestive lymphoma, which are very similar.

A bile test may be done to check for bacterial infection.

The toll is heavier than for simple gastroenteritis, but it avoids blindly treating an illness that lasts for years.

Treatment

The treatment addresses all three components at the same time, depending on which one dominates.

Antibiotic therapy is prescribed when a bile duct infection is suspected or confirmed.

Immunity-modulating treatments, led by corticosteroids, control chronic intestinal and biliary inflammation.

A bile duct protector and liver-supporting supplements are frequently combined.

The management of pain and nausea determines the return to eating.

A suitable diet, often very digestible or with a single protein, is a pillar of long-term treatment.

B vitamin supplements are often necessary as intestinal absorption is impaired.

If the cat does not eat, a feeding tube prevents hepatic lipidosis.

All these treatments are adjusted by the veterinarian according to the results of the examinations and the progress: there is no single protocol.

Treatment depends on the cause and the animal's condition: it must be determined by a veterinarian. No self-medication.

Prevention

No specific prevention is known.

In a cat that vomits or has abnormal stools repeatedly, seeking advice early avoids allowing inflammation to set in and spread.

Do not settle for symptomatic treatment repeated for several months in a row without exploration.

Maintain a stable, quality diet and avoid sudden changes.

Regular weighing at home can detect slow weight loss that the eye cannot see.

Possible complications

Hepatic lipidosis in case of food cessation.

Diabetes mellitus due to repeated damage to the pancreas.

Vitamin deficiencies and severe weight loss due to poor absorption.

Possible progression from chronic intestinal inflammation to digestive lymphoma.

Thickening and obstruction of the bile ducts.

When to see a veterinarian

Your cat has been vomiting or having abnormal stools repeatedly for more than two to three weeks.

He is losing weight even though he eats more or less normally.

His appetite fluctuates: he ignores his bowl for several days then eats again.

It turns yellow, even slightly.

He has previously been treated for pancreatitis, cholangitis or intestinal disease and the signs are returning.

He has not eaten at all for twenty-four to forty-eight hours: consult without delay.

Prognosis

Triaditis is a chronic disease that is controlled rather than cured.

With a precise diagnosis and adjusted treatment, many cats regain a stable weight and a good quality of life for years, at the cost of regular check-ups.

The prognosis is more guarded when a digestive lymphoma is associated, when diabetes sets in or when weight loss is already significant at diagnosis.

Frequently asked questions

Why three organs at the same time?

Because of the cat's anatomy: the pancreatic duct and the bile duct join before reaching the intestine. Inflammation or bacteria pass easily from one organ to another.

Do we really need to take samples?

They are often decisive, because chronic inflammation and digestive lymphoma give exactly the same signs and the same images. The treatments are very different.

Will my cat need to be treated for life?

Often yes, at least through a suitable diet and regular monitoring. Medication treatments are adjusted downward when the situation stabilizes, always on the veterinarian's decision.

Is it contagious to my other cats?

No. It is a chronic inflammation specific to animals, without transmission to another cat or to humans.
