Essentially, Crohn’s disease means that the digestive system will become inflamed – sometimes all the way from the mouth to the anus. When Sophie’s disease flares up, she is left with mouth ulcers, fatigue, an upset stomach and abdominal pain. She can lose weight (IBD prevents her from being able to absorb the nutrients from food), she can develop fistulas or abscesses, which is where the digestive system creates an abnormal tract between different sections of the bowel or the bowel and skin. It can lead to problems with the joints, eyes and skin. “It really is more than just an upset stomach!” she says.
