Irritable Bowel Syndrome (IBS) is a very painful condition which can easily be exacerbated by stress. Causes of the condition aren’t always understood but we know it can run in families; it certainly does in mine.
The term “irritable” makes it sound like a minor inconvenience. In my opinion this does the sufferers of IBS a disservice.
IBS can quickly become a tsunami of excruciating, burning pain often out of nowhere and causing the sufferer to fold over in agony, helpless. I’ve known people to faint from this level of pain; in the scales of suffering this is not a minor irritation.
