What IBS can involve
Irritable bowel syndrome is a common long-term condition of the digestive system. It brings stomach pain, bloating, diarrhoea, constipation or a mix of them, often with urgency, nausea and a tiredness that has nothing to do with sleep. Nothing shows on a scan, which does not make it any less real.
Food, stress, hormones and sleep can all play a part, and the pattern is different for everyone. A calm daily record of what happened — and what it cost you — is what makes your own pattern visible, and makes it easier to say out loud.
IBS is thought to affect somewhere between 1 in 10 and 1 in 25 people worldwide.
