If you’re going abroad there’s a 60% chance you’ll experience some form of diarrhoea. Our Diarrhoea consultation provides the medicines you’ll need to recover quickly. Dr Felix offers the oral antibiotic cirprofloxacin to treat most bacterial causes of diarrhoea, medicines to treat loose bowels and oral rehydration sachets to combat dehydration. Diarrhoea is passing looser or more frequent stools than is normal for you. It affects most people from time to time and is usually nothing to worry about.

What causes diarrhoea?

There are many different causes of diarrhoea, but a bowel infection is a common cause in both adults and children. Gastroenteritis can be caused by:
  • a virus, such as norovirus or rotavirus
  • bacteria, which is often found in contaminated food
  • a parasite
The symptoms associated with diarrhoea can vary depending on the cause. For example, if your diarrhoea is caused by an infection, you may also have a fever and severe stomach cramps. In adults, bouts of diarrhoea can sometimes be the result of anxiety or drinking too much coffee or alcohol. Diarrhoea can also be a side effect of certain types of medication.

Diarrhoea can have a number of associated symptoms depending on the cause and who is affected.

In terms of severity, you may only have slightly watery stools and a brief upset stomach, or your stools may be very watery for a prolonged period.

Many people with diarrhoea experience stomach cramps and a frequent, urgent need to go to the toilet. Other common symptoms associated with diarrhoea include

  • nausea and vomiting
  • headache
  • loss of appetite


Severe or persistent diarrhoea can cause dehydration.

In children, symptoms of dehydration include:

  • irritability or drowsiness
  • passing urine infrequently
  • pale or mottled skin
  • cold hands and feet
  • feeling increasingly unwell

In adults, symptoms of dehydration include:

  • tiredness and a lack of energy
  • loss of appetite
  • nausea
  • feeling light headed
  • dizziness, particularly when standing up
  • dry tongue
  • sunken eyes
  • muscle cramps
  • rapid heartbeat

If dehydration is left untreated it can become severe.
Severe dehydration is a medical emergency and requires immediate medical attention.

Diarrhoea usually occurs when fluid cannot be absorbed from the contents of your bowel, or when extra fluid is secreted into your bowel, causing watery faeces.

Traveller’s diarrhoea is usually caused by ordinary bacteria the body is not used to. Other bacteria such as salmonella can also cause traveller’s diarrhoea.

Travellers’ diarrhoea usually lasts 2 to 4 days during which time people are often bed bound. In a few cases traveller’s diarrhoea can lead to serious illness and even long term bowel problems.

Dr Felix offers the following treatment:

  1. Loperamide 2mg capsules
  2. Azithromycin 250mg tablets
  3. Ciprofloxacin 500mg tablets

A short course of the antibiotic ciprofloxacin or azithromycin together with the anti-diarrhoeal Loperamide is effective in treating traveller’s diarrhoea. An anti-sickness tablet such as Avomine will also relieve symptoms and help to prevent dehydration. These standby treatments work best if taken as soon as diarrhoea starts.

Azithromycin is a slightly more effective antibiotic for the treatment of traveller’s diarrhoea in South Asia (Pakistan and India, etc.) and South-East Asia (Thailand and Laos, etc). In other parts of the world ciprofloxacin is the preferred antibiotic.

There is no vaccination that can protect you from all possible causes of travellers’ diarrhoea. The best way to avoid it is to practice good food and water hygiene while abroad.

Preventative antibiotics are not recommended if you are fit and healthy. If you have a serious health condition that could be made worse if you get diarrhoea, your GP may consider prescribing preventative antibiotics. Speak to your GP if this applies to you.

If you are travelling in a country where standards of public hygiene are low and there is a risk of water contamination, for example some African or Asian countries, avoid the following food and drink:

  • tap water
  • fruit juices (if sold by a street vendor)
  • ice cream or ice cubes
  • shellfish
  • eggs
  • salads
  • raw or undercooked meat
  • peeled fruit
  • mayonnaise
  • sauces

Food and drink that is generally safe to eat includes:

  • sealed bottled water produced by a recognised international manufacturer
  • freshly cooked food, such as soup or stir-fry
  • canned food
  • food in sealed packs
  • fresh bread
  • unpeeled fruit
  • tea or coffee
  • alcohol
