Diarrhoea is defined as a change in consistency of the faeces to a more liquid and loose consistency.
Diarrhoea is a reasonably common condition, more noticeably so in young or elderly animals and may be accompanied by vomiting or weight loss.
Causes of diarrhoea include (among others):
- dietary indiscretion
- infectious causes
- food hypersensitivity
- systemic disease such as hyperthyroidism or pancreatic insufficiency
- inflammatory bowel disease
Many cases will respond to dietary adjustment and parasite control, but persistent or severe cases will need further investigations.
The investigations will include a full clinical examination followed by a combination of faecal analysis, blood tests, diet change and, if the diarrhoea persists, ultrasound examination and intestinal endoscopy or biopsies may be required.
