Feline infectious anemia (FIA) is an infectious disease found in felines, causing anemia and other symptoms. The disease is caused by a variety of infectious agents , most commonly Mycoplasma haemofelis (formerly called Haemobartonella before Haemobartonella and Eperythrozoon species were reclassified as mycoplasmas ).
They are considered to cause little disease, but occasionally cause vomiting and diarrhea and, rarely, peptic ulcer disease with anemia. [6] The eggs of gastrointestinal hairworms are oval, about 60-70 × 35-40 μm in size, and can be detected by flotation techniques.
About half of cases are due to peptic ulcer disease (gastric or duodenal ulcers). [3] Esophageal inflammation and erosive disease are the next most common causes. [3] In those with liver cirrhosis, 50–60% of bleeding is due to esophageal varices. [3] Approximately half of those with peptic ulcers have an H. pylori infection. [3]

Depending on the amount of the blood loss, symptoms may include shock. Upper gastrointestinal bleeding can be caused by peptic ulcers, gastric erosions, esophageal varices, and rarer causes such as gastric cancer. The initial assessment includes measurement of the blood pressure and heart rate, as well as blood tests to determine the hemoglobin.
Gastric antral vascular ectasia (GAVE) is an uncommon cause of chronic gastrointestinal bleeding or iron deficiency anemia. [1] [2] The condition is associated with dilated small blood vessels in the gastric antrum, which is a distal part of the stomach. [1] The dilated vessels result in intestinal bleeding. [3]
Peptic ulcer disease is when the inner part of the stomach's gastric mucosa (lining of the stomach), the first part of the small intestine, or sometimes the lower esophagus, gets damaged. An ulcer in the stomach is called a gastric ulcer , while one in the first part of the intestines is a duodenal ulcer . [ 1 ]
[1] [2] Complications may include stomach bleeding, stomach ulcers, and stomach tumors. [1] When due to autoimmune problems, low red blood cells due to not enough vitamin B12 may occur, a condition known as pernicious anemia. [3] Common causes include infection with Helicobacter pylori and use of nonsteroidal anti-inflammatory drugs . [1]
