Author: admin, 30.05.2015Cats and dogs commonly suffer from upset digestive systems causing vomiting or diarrhea, or both.
In many cases, the cause of the digestive upset is minor; however, vomiting and diarrhea can be symptoms of a serious illness. The digestive system has the very important job of keeping your pet hydrated by bringing water into the body and supplying your pet with nutrients from food. The food remains in the stomach for one to two hours, and muscular valves on either end of the stomach keep the food from escaping while it is being digested. A long, muscular tube that loops around within the abdomen is the small intestine, and it is made up of three separate sections. The large intestine, also known as the colon, is a large, muscular tube that connects the small intestine and the anus. Vomiting in pets is typically caused by an irritant that affects either the stomach or the duodenum, which is the first section of the small intestine. Viral or Bacterial Infection: Other common causes of vomiting include infections as a result of a virus or, less commonly, bacteria. Parasites: Another common cause of vomiting, which affects young pets in particular, is parasites.
Serious Illness: Vomiting is also a symptom of some serious illnesses, such as cancer, liver disease or kidney disease. Diarrhea in pets usually results from an irritant occurring at the end sections of the small intestine or in the large intestine. Fat is harder for cats and dogs to digest, which can cause irritation in the colon resulting in diarrhea. An obstruction in the lower end of the small intestine or in the colon can also cause diarrhea; an obstruction in this area of the digestive tract often causes small amounts of blood to be expelled rather than feces. Fresh, red blood and mucus are often an indication of an injury to the colon, such as from an obstruction. Saliva mixes with the food, and an enzyme in the saliva begins to break down the starches in what your pet has eaten.
A process called peristalsis causes the muscles of the esophagus to contract in waves that push the chewed food down the length of the esophagus and into the stomach. Hydrochloric acid is also produced in the stomach, and the acid further breaks down the food for easier digestion. Muscles in the stomach keep the food moving around among the acid and pepsin to further the process, and then the food passes into the small intestine.
Irritation is most often caused by a cat or dog eating something that is not digestible, such as a bone, a stick or synthetic material, such as plastic. Parasites, such as roundworms or hookworms, can cause vomiting as the body tries to expel the worms. A puncture of the bowel caused by an obstructed object can cause the toxic contents of the intestines to spill into the abdominal cavity, causing a serious and sometimes fatal condition known as peritonitis.
Bile reduces lumps of fat into smaller pieces, and the digestive enzymes break down the fat even further. A disease of the liver or kidneys causes toxins to build up in the body that causes irritation of the digestive system leading to vomiting.
