Symptoms of Diarrhoea

We all know what happens when you get diarrhoea. Frequent, loose and often watery stools—“the runs”—are par for the course. But there are other symptoms too, which you may or may not experience, depending on the cause of your illness:

  • Stomach pain
  • Wind and bloating
  • Fatigue and tiredness
  • Nausea and/or vomiting
  • Incontinence

While things like stomach cramps and diarrhoea are common, there are some rather more colourful symptoms, too. You may notice green diarrhoea, for example. Your stools can turn green in colour thanks to food poisoning, fast-moving bile or resulting from use of laxatives.

Diarrhoea after eating

Sometimes, the above causes can trigger diarrhoea while you’re eating, or shortly after you’ve finished a meal. Particularly if you’re already suffering from an upset tummy, the bowel and the nerves that control its behaviour are already irritated. This means that as the stomach and small intestine stretch with food and the nerve reflexes which trigger you to need the toilet are more easily stimulated.

Painful and persistent diarrhoea

Some symptoms are less common and might be a sign of something more serious. If you’ve had persistent diarrhoea for more than three or four days, or notice any of the following symptoms, then it’s recommended you get in touch with your GP immediately:

  • Blood in your stool or dark black stools
  • Mucus passed with no stools
  • Severe pain in your abdomen or rectum
  • Fever
  • Dehydration

In these more serious cases, your doctor will probably need to take a stool sample and send it off for testing.
