Traveller's Diarrhoea

Traveller’s diarrhoea’ is the term used to describe diarrhoea experienced by people travelling to foreign countries. It is most common in young adults and can affect up to 60% of travellers. High risk destinations include Africa, Asia, the Middle East and Latin America and the condition is most likely to occur in people travelling from developed to developing countries. In the majority of cases, traveller’s diarrhoea can last for 5-8 days and can therefore be limiting to a holiday experience as well as a health concern. As diarrhoea often leads to dehydration, it is important to rehydrate the body by drinking plenty of fluids (preferably water, fruit juice or soup) and avoiding dairy, coffee and alcohol.

Causes and Prevention

In most occurrences, traveller’s diarrhoea is caused by bacteria from contaminated food or water in a foreign environment. To reduce the risk of developing this illness there are simple precautions travellers can take, mainly avoiding drinking tap water, ice, unpasteurised milk and dairy. There are also certain foods which can present a risk of transmitting bacteria, including raw or undercooked meat, poultry, seafood, raw fruits and vegetables.


In general, the symptoms of traveller’s diarrhoea are experienced within the first week or two of being in a foreign environment. They usually begin abruptly and can either occur during travel or soon after returning home. The main symptom is an increase in frequency of bowel movements (typically 3 or more loose stools in 24hrs) which can also be accompanied by other symptoms including cramps, nausea, vomiting, fever, bloating and loss of appetite.

Ciprofloxacin Treatment

Ciprofloxacin is an antibiotic which effectively treats enteric bacterial infections by preventing the reproduction of bacteria. It is therefore not used in cases of diarrhoea caused by a virus or parasite. It is generally accepted that a sudden onset of traveller’s diarrhoea is caused by a bacterial infection and can be treated accordingly using ciprofloxacin.

The Ciprofloxacin 500mg tablets should be taken twice a day at equally spaced intervals for up to 3 days and it is advised to drink plenty of water while taking this medication to avoid developing kidney problems. Ciprofloxacin should be used in circumstances where there is no immediate medical assistance available. It is possible to request a private prescription in advance of travelling if it is expected there will be no access to a doctor. DrFelix also offers other antibiotics like Azithromycin and Loperamide to treat traveller’s diarrhoea.

Ciprofloxacin Side Effects

The most common side effects of using ciprofloxacin are feeling or being sick and diarrhoea, although these only affect 1 in 10 users. There are no known interactions between alcohol and ciprofloxacin.

Rare side effects of this medication include, but are not limited to; bloody or black stools, changes in urination, chest pain or discomfort, chills or fever, dizziness or light-headedness when standing suddenly, and muscle pain or stiffness. It can also cause swelling or tearing of a tendon, especially in the Achilles tendon of the heel, which is more likely in people over 60, those taking steroid medication, or people who have had a kidney, liver or lung transplant.

Acne: Diagnosis, Causes and Treatment

Acne is a very common skin condition characterised by the appearance of spots and pimples on and around the face.

All About Cystitis

Cystitis is a medical term for bladder inflammation. While most of the time, inflammation is caused due to bacterial infection, often it can be caused by secondary factors. It is very common in women, and very rare in men. More than 50% of women experience cystitis at least once in their lives.

Altitude Sickness: Symptoms, Causes and Treatment

Have you ever felt weak or suffered from a headache when you rode on a plane? Or maybe you felt sick to your stomach and lost your appetite when you hiked up to an elevated location. If something like this has ever happened to you, then you may have been experiencing altitude sickness. This is a general feeling of un-wellness, characterized by specific symptoms, that only affects certain people when they move to high altitudes.

Bladder Infection Home Remedies

While many people who are suffering from cystitis turn to their doctor for a medical treatment, many others prefer to try an alternative bladder infection treatment. Although there’s doubt that a natural bladder infection treatment will work, some of them have been effective, especially when treating mild forms of the condition. However, to best prevent the spread of cystitis, and further complications such as kidney infections, we recommend seeking confirmed medical treatments such as ... Read more
