Treatment

Diarrhoea usuallyclears upwithout treatment after a few days, particularly if it's caused by an infection.

In children, diarrhoea usually passes within five to seven days and rarely lasts longer than two weeks.

In adults, diarrhoea usually improves withintwo to four days, although some infections can last a week or more.

While waiting for your diarrhoea to pass, you can ease your symptoms by following the adviceoutlined below.

Drink fluids

It'simportant to drink plenty of fluids to avoid Dehydration , particularly if you're also vomiting. Take frequent smallsips of water.

Ideally, adults should drink a lot of liquids that contain water, salt and sugar. Examples are soup broth orwater mixed with juice.

If you're drinking enough fluid, your urine will be light yellow or almost clear.

It's also very important for babies and small children not to become dehydrated. Give your child frequent sips of water, even if they're vomiting. A small amount is better than none.

Fruit juice orfizzy drinks should be avoided as they can make diarrhoea worse in children.

If you're breastfeeding or bottle feeding your baby and they have diarrhoea, you should continue to feed them as normal.

Contact your GP immediatelyif you or your child develop any symptoms of dehydration .

Oral rehydration solutions

Your GP or pharmacist may suggest using an oral rehydration solution (ORS) toprevent dehydration if you're at riskfor example, if you're frail or elderly. ORS can also be used to treat dehydration that has already occurred.

Rehydrationsolutions usually come in sachets availablefrom your local pharmacistwithout a prescription. They are dissolvedin water, and replace salt, glucose and other important minerals that are lostif you're dehydrated.

Children

Your GP or pharmacist may recommend givingyour child an ORSif they're dehydrated or at risk of becoming dehydrated.

The usual recommendation is foryour childto drink an ORS each time they have an episode of diarrhoea. The amount they should drink will depend on their size and weight.

Your pharmacist can advise you about this. The manufacturer's instructions shouldalso give information about the recommended dose.

You may be able to give your baby an ORS if they become dehydrated, but check with your GP, pharmacist or health visitor first.

Eating

Opinion is divided over when and what you should eat if you have diarrhoea. However, most experts agree you should eat solid food as soon as you feel able to. Eat small, light meals and avoid fatty or spicy foods.

Good examples are potatoes, rice, bananas, soup and boiled vegetables. Salty foods help the most.

You don't need to eat if you've lost your appetite, but you should continue todrink fluids and eat as soon as you feel able to.

Children

If your child is dehydrated, don't give them any solid food until they have drunk enough fluids. Once they stop showing signs of dehydration, they can start eating their normal diet.

If your child isn't dehydrated, offer them their normal diet. If they refuse to eat, continue to give themfluids and wait until their appetite returns.

Medication

Antidiarrhoeal medicines

Antidiarrhoeal medicines may help reduce your diarrhoea and slightly shorten how long it lasts. However, they're not usually necessary.

Loperamide is the main antidiarrhoeal medicine used,as it has been shown to be effective and causes few side effects.

Loperamide slows down the muscle movements in your gut somore water is absorbed from your stools. This makes your stools firmer and they're passed less frequently.

An alternative to loperamide isa different type of antidiarrhoeal medicine calledracecadotril, which works by reducing the amount of water produced by the small intestine.

Evidence suggests this medication may be as effective as loperamide for treating diarrhoea.

Some antidiarrhoeal medicines can be bought from a pharmacy without a prescription.

Check the patient information leaflet that comes with the medicine to find out whether it's suitable for you and what dose you should take. Ask your pharmacist for advice if you're unsure.

Don't take antidiarrhoeal medicines if there's blood or mucus in your stools or you have a high temperature (fever).Instead, you should contact your GP for advice.

Mostantidiarrhoeal medicines shouldn't be given to children. Racecadotril can be used in children over three months old if it's combined with oral rehydration and the other measures mentioned above, although not all doctors recommend it.

Painkillers

Painkillers won't treatdiarrhoea, but paracetamol or ibuprofen can help relieve a fever and a headache . If necessary, you can give your child liquid paracetamol or ibuprofen.

Always read the patient information leaflet that comes with the medication to check if it's suitable and find out the correct dose. Children under 16 years of ageshouldn't be given aspirin.

Antibiotics

Treatment with antibiotics isn't recommended for diarrhoea if the cause is unknown. This is because antibiotics:

• won't work if the diarrhoea is caused by a virus
• can cause unpleasant side effects
• can become lesseffective at treating more serious conditions if they're repeatedly used to treat mild conditions

Antibiotics may be recommendedif you have severe diarrhoea and a specific type of bacteria has been identified as the cause.

They may also be used if you have an underlying health problem, such as a weakened immune system.

Hospital treatment

Occasionally, hospital treatment may be needed to treat serious dehydration. Treatment involves administering fluids and nutrients directly intoa vein (intravenously).

Treating the underlying cause

If you've been diagnosed with a specific condition that's causing your diarrhoea, treating this may help improve your symptoms.

For example:

• irritable bowel syndrome (IBS) can be treated with changes to your diet and medications read more about treating IBS
• inflammatory bowel disease can be treated with medications that help reduce inflammation in the bowel
• coeliac disease can be treated by excluding foods containing gluten from your diet read more about treating coeliac disease
• bile acid malabsorption can be treated with medication that helps stop bile building up in the digestive system

Probiotics

Probiotics are live bacteria and yeasts found in some yoghurts and food supplements.

There's some evidence that certain probiotics can slightly shorten a period of diarrhoea, although the evidence isn't yet strong enough to recommend taking them.

There's also evidence to suggest some probiotics may reduce your chances of developing diarrhoea after taking antibiotics .
