Can IBS-D or IBS-C be severe enough to cause malnutrition, and why does it seem so hard to get a proper diagnosis?
This is such a frustrating situation, and it's completely understandable to feel unheard — especially when multiple family members are struggling.
IBS is classified as a functional disorder, meaning there's no visible structural damage to the gut. Because of this, many doctors don't traditionally link it directly to malnutrition. However, here's why it *can* contribute to nutritional problems:
- IBS-D can cause food to move through too quickly, reducing nutrient absorption
- IBS-C can make eating feel uncomfortable, leading people to restrict their diet
- Fear of triggering symptoms often causes people to cut out entire food groups
- Chronic pain and nausea can severely reduce appetite and food intake
Over time, these factors *can* absolutely lead to nutritional deficiencies, even if doctors don't always connect the dots. Regarding diagnosis difficulties, IBS is unfortunately often a diagnosis of exclusion — meaning doctors rule out everything else first. This can lead to long, exhausting journeys before landing on the right answer.
Some helpful steps to consider:
- Ask your GP specifically for a dietitian referral to address nutritional concerns
- Request a gastroenterologist referral if you haven't already
- Keep a detailed food and symptom diary to bring to appointments
- Ask doctors directly about IBS-D and IBS-C as possibilities
You and your family deserve proper answers. Persistence with healthcare providers really does matter here.
