23.4 The Stomach – Anatomy and Physiology
Primary causes of vomiting include acute gastritis often due to eating garbage or other types of dietary indiscretions; the ingestion of large amounts of hair during grooming; ulcers of the stomach; stomach or upper intestinal cancer; parasites; food allergies; the presence of a foreign body stuck in the stomach or upper intestine; twisting and dilation of the stomach; and intussusception which is a telescoping of one part of the intestine into another piece of intestine. My cat Tillie is 16 and has recently been diagnosed with kidney disease following being admitted with dehydration and tooth absorption. She lost her appetite and I was struggling to get her to eat.
Whatâ€™s Causing Your Cat to Vomit?
A. The Raw Meals we stock from Natures Menu are ready-made raw meals for cats and dogs that comply with the guidelines for a complete and balanced pet food. We can also order in any of the Natures Menu just minces though for you to create raw meals for your pet in your own kitchen. When meat is rotted in certain conditions where no bad bacteria can get established, it can be, and in some cultures is consumed by humans. Some researchers suggest there are about 120 thousand types of good bacteria and only about 4 thousand bad ones.
As the pH drops back in to the 2-3 range , G cells slow their release of gastrin. G-cells also release gastrin in response to certain foods – including peptides, amino acides, calcium, and for people certain elements in coffee, wine and beer !. Gastrin has many functions – also stimulating acid release indirectly by signalling ECL cells to secrete histamine. The histamine binds to H2 receptors turning on the acid release pumps. Gastrin also controls the muscular actions of the stomach, gastrin reduces stomach motility, which slows gastric emptying which helps the stomach hold and process a large meal.

It is a simple commercial fact that meat protein is the most expensive component in any pet food, and as a result, there is always commercial pressure to keep meat protein levels to a minimum, thereby keeping costs down of the end product (and / or maximising profits).
Stomach acid dissolves and denatures proteins in the meat. The digested food bits are released in a gradual manner into the small intestine. There, enzymes from a catâ€™s liver and pancreas convert fat into fatty acid, and protein into amino acid. Only a small amount of carbohydrates are digested. Consider taking steps to improve your pet’s diet.
Fast Food is Bad for Pets, Too
Unfortunately, kitties are more likely to show signs of life-threatening hemorrhaging, so cats often present with acute crisis symptoms, but can also have the above symptoms as well. Your pet’s stomach acid is highly acidic, with a pH range of 1 to 2.5.
When you present your pet to the veterinarian because he or she is vomiting, the veterinarian will ask questions in attempt to differentiate between vomiting and regurgitation and to try to determine if your pet is vomiting due to gastric or non gastric disease. Vomiting is an active process.
- More and more, data seem to suggest that species-specific communities in the human gut appear relatively resistant to perturbation [10-11], in large part because the acidic human stomach prevents frequent colonization of the gut by large numbers of food-borne microbes, regardless of whether they are beneficial or pathogenic.
- If you prepare a homemade raw diet for your dog or cat, you donâ€™t include guts.
- Although a minimal amount of carbohydrate digestion occurs in the mouth, chemical digestion really gets underway in the stomach.
- Non-spayed, middle aged female pets can develop a uterine infection called pyometra.
- Your petâ€™s body is well equipped to deal with heavy doses of familiar and strange bacteria because nature builds them to catch, kill and immediately consume their prey.
- High carb meals wonâ€™t need as much acid to digest, so only a small amount of acid is produced.
She has had too much gas with all grainy foods I have tried. She’s been on a grain-free wet and dry food diet for months now since that worked the best (so far) but there are still some issues. She what appears to be “burping” quite frequently and swallows afterward so I guess that’s heartburn maybe.
The role of this mucus is not currently known. Although the walls of the gastric pits are made up primarily of mucus cells, the gastric glands are made up of different types of cells. The glands of the cardia and pylorus are composed primarily of mucus-secreting cells. Cells that make up the pyloric antrum secrete mucus and a number of hormones, including the majority of the stimulatory hormone, gastrin. The much larger glands of the fundus and body of the stomach, the site of most chemical digestion, produce most of the gastric secretions.
Pepsin is solely responsible for protein digestion, and lipase, which is only found in the stomach of carnivores (dogs and cats), begins digesting fats. Also known as gastroesophageal reflux disease (GERD), acid reflux disease is a chronic irritation of the lining of a person’s esophagus by stomach acid.
The uncontrollable reverse flow of gastric or intestinal fluids into the tube connecting the throat and the stomach (esophagus) is medically referred to as gastroesophageal reflux. This may be due to a brief relaxation of the muscular opening at the base of the esophagus (referred to as the sphincter), as well as chronic vomiting. Gastroesophageal reflux is fairly common in cats, and may occur at any age, although younger cats are at greater risk.
Many healthy dogs and cats vomit occasionally without identifying a cause. Sometimes the cause of vomiting is as simple as the pet eating too fast.
Our articles involve contributions from senior veterinarians and are researched thoroughly. They remain the opinion of Vets All Natural however and we would always recommend seeking professional advice specific to your pet from a veterinarian.
It doesnâ€™t take much research to uncover the fact that dogs and cats are designed by nature to eat living foods – unprocessed, raw, nourishing foods. Feeding a commercial formula is a bit like deciding your child can be healthy on an exclusive diet of meal replacement bars.
