Vomiting Blood in Cats (Hematemesis)


Hematemesis, also known as vomiting blood in cats, affects a wide range of cats’ systems depending on its source. The abdominal cavity, where the stomach and intestines are located, may be affected by reasons such as infection, ulcer, tumor, inflammation, various traumas or the presence of foreign substances. Excessive blood loss affects the circulatory system and leads to heart problems or a low heart rate. In the meantime, very rapid breathing occurs due to circulatory failure. And as a result of all this, blood loss in the stomach and intestines and vomiting of blood occur.

Another situation that can cause vomiting of blood is injuries in the esophagus, which is responsible for removing bleeding from the stomach and intestines. On the other hand, if your cat swallows this blood without realizing it after bleeding in the mouth or lungs, the blood going to the stomach will cause discomfort and cause vomiting blood.

What is Blood Vomiting?

Vomiting blood is generally the removal of disorders in the gastrointestinal tract or any bleeding focus in the body by mouth. If you encounter such a situation, let’s continue by reminding you that you should not forget to go to the veterinarian as soon as possible. While vomiting is quite common in cats, vomiting blood, known as hematemesis, is a serious illness in cats that requires an emergency. The blood in a cat’s vomit has a coffee grounds-like appearance that can be distinguished from the blood in the vomit and can be bright red or dark in color. On the other hand, let’s say that it would be more beneficial to consult a veterinarian first when you encounter such a situation, rather than trying to understand what the blood looks like or what the cause might be.

What Does Bloody Vomiting Look Like?

As we mentioned above, blood in the vomit is usually red. However, the color and consistency of the blood also gives us a clue as to why there is blood in the vomit. Bright and red blood flakes in the vomit are mostly a sign of a problem in the upper gastrointestinal tract. If the blood looks like coffee grounds, it indicates a problem further down the gastrointestinal tract, such as the small intestine and large intestine.

Symptoms of Vomiting Blood in Cats

If the blood in your cat’s vomit is bright red, the blood is fresh and is more likely due to damage to the upper gastrointestinal tract.

If the problem persists and you observe any of the symptoms listed below, you should take your cat to your veterinarian immediately.

Diagnosing Blood Vomiting in Cats

Your veterinarian will ask you about certain events or known conditions that may cause vomiting in the first place. Make sure you give the correct answers at this stage and indicate any medication your cat uses regularly. Your doctor can then use a series of tests to determine the cause of your cat’s vomiting blood. He or she can then make a tentative diagnosis based on the condition of the symptoms. However, tests are essential for a definitive diagnosis. For this, in addition to applications such as endoscopy, ultrasound or x-ray, blood and urinalysis may also be requested.

If cancer is suspected, your veterinarian may take a biopsy from the gastrointestinal tract. Also, although veterinarians cannot effectively test vomit samples for disease and other conditions, seeing the appearance of vomit or stool can be helpful for diagnosis. That’s why you can bring a small sample of vomit or stool with you to the vet.

Blood Vomiting Treatment in Cats

Illness: In many cases of vomiting blood caused by the disease, the treatment varies depending on the disease. While some diseases are treated with medication, gingivitis can be treated with a thorough dental cleaning. Your cat may also need hospitalization and intravenous fluid therapy to restore electrolytes and fluids lost during vomiting.

Ulcers: Certain medications are given to prevent ulcers from damaging the lining of the stomach and to help reduce stomach acid. In general, a special or light diet is recommended. Surgical operation with endoscopy can also be performed to locate ulcers.

Cancer: Depending on the location and stage of the cancer, treatment methods may include surgery, chemotherapy or radiotherapy.

Improvement of Blood Vomiting in Cats

Recovery and process vary according to the underlying cause and the recommended treatment method. First of all, you should make sure that you carefully follow your veterinarian’s treatment and recovery instructions. If your cat has gingivitis, you should brush and properly care for her teeth every day, as long as it won’t be painful for your cat. In fact, your veterinarian will find plenty of advice about dental care. If your cat has been given medication to treat gastrointestinal ulcers, you should remember that you should apply the medication for the entire recommended treatment period, even if symptoms begin to improve.

If your cat has had surgery, make sure it does not irritate the surgical site. Remember to provide a safe and warm place for your cat to rest after any major surgery or treatment. Finally, make sure that your cat’s drinking water is accessible and full at all times. At the same time, your veterinarian will give you some advice on dietary changes.
