Parents often search teen Crohn's nutrition or IBD growth delay after noticing clothes fitting differently or growth charts flattening. Active inflammation steals calories and nutrients; healing requires enough fuel.

Growth and Weight Monitoring

Pediatric gastroenterologists track height velocity and BMI. Falling off your curve during puberty warrants discussion, medication adjustment, enteral nutrition, or supplement plans may be options your team already uses.

Protein and Key Nutrients

• Protein: Eggs, yogurt, tender meats, tofu, smoothies, especially after steroid courses.
• Calcium & vitamin D: Bones are building now; ask about labs and fortified foods.
• Iron: Fatigue plus heavy periods or intestinal loss, common teen combo; test, don't guess.

School Cafeteria Survival

Identify two to three go-to meals that do not worsen your symptoms. Pack backup snacks if lines are long. Hydration matters in hot climates and during sports, see hydration tips for IBD.

Restrictive Diets and Social Eating

Low-residue or low-FODMAP trials should be time-limited and supervised. Teens need flexibility for pizza nights and team dinners when possible, perfection is not the goal; adequacy is.

Tracking Helps Conversations

Log meals, energy, and stools in IBDPal before dietitian visits. Patterns beat memory when school weeks blur together.
