These factors create conditions that allow the overgrowth of bad bacteria, putting the gut microbiome out of balance. This may cause digestive symptoms such as bloating, gas, abdominal pain, diarrhoea and even food sensitivities to arise. Or if left untreated it may lead to the development of gastrointestinal conditions like irritable bowel syndrome (IBS), gastritis, reflux, Small Intestinal Bacterial Overgrowth (SIBO), diverticulitis or Crohn’s disease.
