2. Crohn’s Disease
Another life-long condition, Crohn’s Disease is similar to gluten intolerance insofar as it affects the small and large intestines and can be improved by following a strict diet. The symptoms are similar too—acute stomach cramps, diarrhea, fatigue and weight loss. However, unlike gluten intolerance, Crohn’s Disease flares up and goes into remission for either weeks or months at a time. This is a relatively rare condition, which is why it is so often misdiagnosed.
Giardiasis (also called giardia) is also similar to gluten intolerance, causing symptoms like diarrhea, a gassy stomach, flatulence, bloating; abdominal cramps and nausea. The condition is caused by a parasite from contaminated water—usually untreated water in rivers or lakes. Individuals who have this infection can have it treated by a specific course of medicine from their doctors, though it’s worth noting that giardiasis sometimes passes through the system and goes away by itself.
