Review of the use of probiotics to treat irritable bowel syndrome

Irritable bowel syndrome treatments vary hugely as do the symptoms, which vary from mild abdominal discomfort, to severe cramping pain, diarrhoea, constipation, bloating and gas. Nobody really knows the causes although many people believe that it is stress related and sometimes genetic.

Prescription medicines are available but many people find that these can trigger side effects such as nausea, headaches and chest pain. Low-dose antidepressants can also be helpful.

Popular over the counter medicines include anti-diarrhoea medicines such as Imodium but these should only be taken as needed. Laxatives such as bran or Fybogel are popular, these are bulk forming laxatives. However, some people find these make symptoms worse. Lactulose is an alternative to bulk-forming agents; it increases the amount of water absorbed into the large bowel but can cause wind. Stronger bowel-stimulating laxatives such as Senna should not be used routinely unless under a doctor’s advice. Antispasmodic medicines such as Colofac and peppermint oil capsules may help with pain and wind.

Increasing in popularity as Irritable bowel symptom treatments are probiotics.

These are food supplements containing live bacteria and yeasts that help restore the balance of the bacteria in the gut. Although bacteria are often thought to be harmful

There are many good bacteria that live in our bodies that keep us healthy. Good bacteria in the gastrointestinal tract may prevent harmful organisms from growing in the bowel or entering the body through the intestine.

Probiotics are available as food supplements in capsule or tablet from pharmacies or health food shops. Always read the patient information leaflet and follow the recommended dosage. Probiotics can also now be bought as yoghurts or drinks.
