Diarrhoea

Food nutrients are absorbed in the small intestine

The waste is pushed into the large intestine (bowel) where water is removed. The resulting faeces is stored temporarily within the rectum then passed out of the body through the anus. Faeces are usually firm, moist and easy to pass.

Diarrhoea is the frequent passing of loose, watery and unformed faeces. Acute diarrhoea is the sudden onset of 3 or more loose stools per day, lasting less than 14 days. The most common cause of acute diarrhoea is an infection of the intestines, such as gastroenteritis or food poisoning.

Viruses are responsible for most cases

The intestinal lining becomes irritated and inflamed, which hinders the absorption of water from food waste. In severe cases, the intestinal lining may even leak water. Generally, acute diarrhoea resolves after a day or 2.

Chronic diarrhoea, which lasts 4 weeks or more, can be caused by a range of conditions that affect the intestines, including inflammatory bowel disease (IBD). The symptoms associated with diarrhoea include:

• frequent passing of loose watery faeces. In most cases acute diarrhoea is self-limiting
• will resolve by itself within a day or 2

However, contact your doctor immediately if you experience serious symptoms including: (temperature greater than 38 ºc). , even one day of diarrhoea can be dangerous. It’s safer to see your doctor as soon as possible.

Acute diarrhoea can be life threatening to babies and young children. This is because their smaller bodies are more vulnerable to dehydration.

If your baby or young child develops diarrhoea, seek medical attention straight away.

A bout of diarrhoea can be caused by a wide range of disorders, infections and events including: medications, particularly antibiotics. Person to person spread, as well as contaminated food and water are common infectious causes of acute diarrhoea. Some of the infectious agents known to cause diarrhoea include:

• Some of the causes of chronic diarrhoea include including antibiotics magnesium
• antacids that contain magnesium laxatives drugs for treating – the bowel is blocked by hard
• impacted faeces
• but some liquids manage to seep past the blockage

This condition, called ‘spurious’ or ‘overflow’ diarrhoea, is more common in the elderly Successful treatment depends on diagnosing the cause. Investigations may include: – the insertion of a slender instrument into the anus so that the doctor can look at the bowel lining.

Always see your doctor if you experience serious symptoms

Babies and young children with diarrhoea need prompt medical attention. Treatment for diarrhoea depends on the cause, but may include:

• oral rehydration drinks to replace lost salts

These drinks are available from pharmacies

An alternative is one part unsweetened pure fruit juice diluted with 4 parts of water anti-diarrhoeal medications, but only on the advice of your doctor.

If your diarrhoea is caused by infection, anti-diarrhoeal drugs may keep the infection inside your body for longer treatment for any underlying condition, such as inflammatory bowel disease.

Most cases of acute diarrhoea are potentially infectious to others.

Viruses are easily spread, mainly through direct contact with vomit or faeces from an infected person, or through contact with a contaminated object or surface. Occasionally, the virus may be transmitted by airborne particles generated from vomiting and diarrhoea. after going to the toilet and before handling food.

People looking after a person with the virus must also wash their hands thoroughly. Alcohol-based handwash solutions, available from pharmacies, have been shown to be better at reducing the spread of infection than soap and water, and are less drying to the skin. Anyone with acute diarrhoea should stay at home if possible to reduce the spread of infection.

It is strongly recommended not to visit hospitals and nursing homes, and not to swim in public pools. It may help to make a few short-term dietary adjustments while your bowels recover from acute diarrhoea. Be guided by your healthcare professional, but general suggestions include: or spicy foods.

Avoid alcohol

Increase consumption of starchy foods like banana, rice and bread.

Increase consumption of yoghurt containing live cultures

Diarrhoea in babies and young children can be caused by fruit juice, so limit these drinks. Need treatment today?
