Relief That Travels With You: Relief That Travels With You

Most people who travel will have experienced diarrhoea or frequent loose stools during their trip or shortly after their return home, this is classed as Traveller’s diarrhoea (TD). Unsurprisingly it is the most common illness related to travel internationally and worldwide affects a whopping 80 million travellers every year.

Estimates vary as to how often it occurs from 10-56% of travellers depending on whether you are travelling to a high-risk country, the season, where and what you eat and the types of activities you take part in. High-risk countries for TD include Central and South America, South and Southeast Asia and West, East and North Africa, or areas where sanitation and hygiene are poor. Although, outbreaks can also occur on cruise ships and hotels where people are in close contact.

Most people understand that TD can develop from drinking or eating food that is contaminated with microorganisms such as bacteria or the toxins they release. However, diarrhoea can also be caused by a change in your diet, drinking more alcohol, stress from travel, or some people are just more susceptible. Bacteria such as Campylobacter, E.coli, Shigella and Salmonella are the most common causes followed by norovirus and rotavirus.  Parasites can also cause TD but tend to be less common.

According to the National Institute for Health and Care excellence (NICE), TD is the passing of 3 or more unformed stools (diarrhoea) within 24-hours, and at least one additional symptom including abdominal pain or cramps, nausea, vomiting, fever, or blood in the stools. It can be of mild, moderate or severe intensity, depending on if it prevents you from taking part in planned activities and is labelled “persistent” if it lasts for more than 2 weeks. Most people experience mild TD which lasts for 3-5 days, but it can be disturbing and often causes an urgent need to visit the toilet.

The first step is rehydration which is especially important for children, elderly, pregnant women and those with pre-existing illnesses. To prevent dehydration, you can take oral rehydration salts mixed in clean water. These help with hydration and to correct electrolyte imbalances, but do not reduce the duration of diarrhoea or stool frequency.

Although adults can use loperamide or bismuth subsalicylate to relieve mild-moderate diarrhoea they should not be taken for longer than 2 days, or in children under 12 years, if you have a high fever (common in TD), or severe tummy pain, if you have blood or mucous in your stool, or those with inflammatory bowel disease. Both should be used with caution and the patient information leaflet followed directly, as they can have severe side effects. As loperamide slows gut motility, the microorganism causing the diarrhoea can remain in the gut for longer and people who are interested in improving their gut health are looking for safer alternatives.

Oral intestinal adsorbents such as ENTEROSGEL are another option that can be considered as an effective treatment for TD. ENTEROSGEL is classified as a medical device because of the way it works in the gut, removing bacterial toxins and viral particles, not being absorbed into the body and being completely expelled in the stools.  ENTEROSGEL offers a safe treatment option for children (from age 0+years) and adults and is available as an OTC treatment and on prescription. Scientific studies have shown it can capture bacterial toxins from E. coli, C. difficile and Shigella and rotavirus which are known to cause TD in people. Clinical studies have proved it reduces the duration of all types of diarrhoea not just TD and is the only treatment available that is safe for children from 0+ years.

ENTEROSGEL has the advantage that it can be used as a treatment mixed in oral rehydration salts to reduce duration of diarrhoea and stool frequency, in all age groups even vulnerable patients, with only few minor side effects.

Although probiotics recently have become popular for many gut-related conditions. For TD the scientific literature currently doesn’t suggest any benefit from taking them, although they may help replenish the microbiome with beneficial bacteria after an episode.

There are currently no vaccines available to prevent TD, so prevention is your best means of defence. It’s important to follow basic food and water hygiene measures and be prepared by taking ORS and Enterosgel with you. You never know if you will be able to find these abroad.

Regular hand washing with soap can help prevent TD and although alcohol hand gel is useful, it is less effective than soap against some pathogens. It’s also a good idea to avoid buffets and street food, raw fish, salad and ice and to peel fruits and raw vegetables. You should also avoid swallowing any pool water when swimming, and use bottled water to drink and clean teeth.
