Diarrhea and vomiting

Regurgitation is the passive expulsion of matter from the mouth, upper throat (pharynx), or esophagus. In dogs, the expelled matter often takes the appearance of chewed food combined with a little saliva or mucus. It can also be tube-like in shape. 

Regurgitation is the act of involuntarily expelling swallowed food from the esophagus out of the mouth. It can be identified by the tubular shape of the ejected matter as well as the passivity of the process. 

Mucus in the stool of cats is a natural lubricant within or surrounding feces that assists with the passage of waste through the digestive system. A small amount of mucus in stool is common in cats, while large amounts are not.

Canine bowel incontinence is the inability to control defecation. Incontinence is distinct from inappropriate elimination or house-soiling, in that the bowel movements occur without the dog’s awareness.

Mucus in the stool is a viscous substance that lubricates feces to pass through the intestinal tract. A large quantity or frequent recurrence of mucus in the stool is uncommon for dogs warranting non urgent veterinary investigation.

Canine Parvovirus (CPV) is a life threatening viral infection of the gastrointestinal system in dogs. It primarily affects dogs under 2 years old but is most common in puppies between 3-8 months old.

Bowel incontinence in cats is involuntary passage of feces, and appears to happen without awareness. This symptom is not to be confused with straining to defecate or inappropriate defecating/house soiling.

Inflammation of the gallbladder (cholecystitis) and inflammation of the bile ducts (cholangitis) are inflammatory conditions of their respective organs.

Constipation is characterized by difficulty defecating with the resulting feces being dry and hard. This symptom is slightly different from tenesmus, which is straining to defecate with an empty or irritated colon, however both of these symptoms appear similarly to pet owners

Bloody stool describes the presence of blood in feces and includes digested blood (melena) or undigested blood (hematochezia). Bloody stool is a non-specific symptom triggered by many conditions such as mild, dietary-induced colitis to emergency conditions such as parvovirus infection, hemorrhagic gastroenteritis, or bleeding disorders

Diarrhea in horses is stool that contains more than the usual amount of water, ranging in consistency from loose “cow plop” defecation to projectile defecation of mostly liquid.

Cholestasis is a reduction in bile flow or production from the liver. Bile functions to neutralize stomach acid as it enters the intestines, assists in digestion of fats, and excretion of other metabolites

Canine cholangitis is a rare inflammation that affects the liver, bile ducts, and gallbladder. The most common cause of cholangitis is an infection that ascends from the intestinal tract to the liver

Constipation is straining to defecate when the colon is full. Constipation is not to be confused with diarrhea which may cause straining to defecate when the colon is empty and irritated.

Inflammatory bowel disease (IBD) is a group of idiopathic (spontaneous) conditions that lead to chronic inflammation of the digestive tract.

Colic simply refers to pain in the abdomen, and does not provide any specific details regarding what organ system is affected or what underlying condition is occurring.

Colitis refers to inflammation of the colon, which typically causes diarrhea, increased bowel movements, and increased urgency to defecate.

Inflammatory bowel disease (IBD) is a term used for a group of inflammatory gastrointestinal diseases that are the result of disturbed interactions between the immune system, microbiotica of the intestine, and environmental inputs.

Allergies are common in cats, similar to other species. Harmless proteins in the environment (allergens) stimulate the immune system, which overreacts and produces a strong inflammatory response.

Food allergies occur when the immune system overreacts to an ingested protein.

Food allergies are a reaction of the immune system to specific proteins within the diet.

Vomiting is the involuntary expulsion of the contents of the stomach through the mouth and nose. It involves abdominal contractions and may produce bile.

Motion sickness is the feeling of nausea during land, sea, or air travel caused by excessive or unpredictable movement.

A gastrointestinal (GI) foreign body obstruction is the result of ingesting a foreign object that is not able to pass through the body naturally.

Enteritis refers to inflammation of the intestines, while gastroenteritis refers to inflammation of both the intestines and the stomach

Gastrointestinal blockages most commonly occur when a dog swallows a large, indigestible object. As the object moves through the gastrointestinal tract, it encounters progressively smaller tubes. Eventually, it becomes stuck, and blocks the flow of intestinal contents.

Vomiting is the act of forceful contraction of the abdominal muscles leading to the ejection of ingested material through the mouth.

Whereas humans get sneezy and sniffly at certain times of the year, some cats get red, itchy skin and secondary skin infections for the same reason: seasonal allergies.

Megacolon is the dilation and dysfunction of the colon resulting in difficulty evacuating stool.

Dietary indiscretion occurs when a cat eats non-food items or food outside of its typical diet.
