what is diarrhoea? How is it caused? How can it be prevented?.
Answers
Answer:
Diarrhoea is usually caused by a virus, or sometimes, contaminated food.
causes:
Acute (or brief) diarrhoea is usually caused by a bacterial (eg, salmonella), viral (eg, norovirus or rotavirus), or parasitic (eg, giardia) infection of the bowels. Diarrhoea caused by any of these infections is referred to as gastroenteritis.
Travel to places where the climate or sanitary practices differ form one's home country may cause short-term gastroenteritis (eg from contaminated food or water) and is known as traveller's diarrhoea. Diarrhoea associated with jet lag will usually subside in a matter of days without treatment.
The most common causes of chronic diarrhoea are underlying diseases or conditions, including:
Gluten intolerance (coeliac disease)
Lactose intolerance (inability to properly digest lactose in dairy products)
Irritable bowel syndrome
Chronic bowel infection
Inflammatory bowel diseases, such as Crohn’s disease and ulcerative colitis
Bowel cancer.
prevention:
Hand washing is one of the most effective ways of preventing the spread of viruses and bacteria that can cause diarrhoea. You should always wash your hands thoroughly after using the toilet, changing nappies, and before meals.
The following rules when preparing food can also help prevent diarrhoea:
Always put foods that could spoil in the fridge
Ensure that meat is cooked thoroughly
Avoid eating raw meats, fish, and shellfish unless you are sure that they have been freshly prepared and are from a reliable source
Never place cooked meat on surfaces or plates that have held raw meat
Disinfect bench tops, stove tops, and chopping boards with a diluted bleach solution.
