Editor’s note: This is the final installment in a series of columns by Mary Horsley about IBD-related symptoms that are “Beyond the Bathroom.” Read Part One, Part Two, and Part Three. Inflammatory bowel diseases like Crohn’s disease, and ulcerative colitis, often cause problems outside of the restroom for many of their warriors. To continue the “Beyond the Bathroom” series, we will examine weight loss and weight gain, related issues like vomiting and loss of appetite, and IBD symptoms related to hair, vision and cognition. When inflammation takes over, sometimes the last thing a Crohn's or colitis patient wants is to eat food. Fearful of inflicting pain upon one's self, a patient will avoid meals, knowing how it will affect the body (and bowel). As a result, patients tend to lose weight, suffer malnutrition, and experience bouts of diarrhea, constipation, or both. Warriors may lose weight due to lack of eating, or an inability to keep food down, and experience nausea and vomiting symptoms, too.
