Turning 18 With IBD: Pediatric-to-Adult Transition Checklist

Turning 18 with inflammatory bowel disease means more than a birthday. For teens with Crohn's disease or ulcerative colitis, it marks the point where responsibility for a lifelong condition starts shifting from a parent to the young adult. Crohn's disease is a chronic condition in which the immune system causes inflammation in the digestive tract, and ulcerative colitis is a chronic disease that inflames and ulcerates the lining of the large intestine. Both are managed over decades, not cured, so a smooth pediatric to adult IBD transition protects the progress made during childhood. This checklist walks through what to organize before, during, and after the handoff.

Why the pediatric to adult IBD transition matters

A large share of IBD begins early in life. The Crohn's & Colitis Foundation reports that roughly 6 to 15 percent of children with IBD are diagnosed before age 6, and many more are diagnosed during the teenage years. That means a young patient may have spent a decade or longer in a pediatric practice where a parent scheduled visits, tracked medications, and spoke with the doctor. Adult gastroenterology works differently. Visits tend to be shorter and focused on the patient rather than the family, and procedures are more often done under conscious sedation while the patient is awake. Preparing for that change protects disease control during a period when gaps in care can trigger flares.

Start earlier than you think

Transition is a process that unfolds over years, not a single appointment. Pediatric IBD teams are encouraged to introduce disease knowledge and self-management concepts in patients as young as 12, with the actual transfer of care usually happening between ages 18 and 21 depending on maturity. The national Got Transition framework similarly recommends that clinics begin discussing a transition plan when a young person is 12 to 14 years old. If your family has not had this conversation yet, it is reasonable to raise it directly with your pediatric gastroenterologist. Turning 18 does not require an instant switch, and the American Academy of Pediatrics stresses that youth do not suddenly become adults at 18 regardless of their new legal status.

Build self-management skills before the handoff

The core of turning 18 with Crohn's disease or ulcerative colitis is a teen taking over their own medical care. The Crohn's & Colitis Foundation lists concrete skills to practice, including naming your medications and their side effects, taking medications on your own, and learning your health insurance information. Building on that, adult-care readiness generally means understanding your diagnosis and disease history, knowing medication names and doses, requesting refills, managing your own appointments, and contacting your insurer when needed. These abilities are worth rehearsing while a parent is still available to coach. A practical approach is to have the young adult lead part of each remaining pediatric visit, speaking directly with the clinician and asking questions without a parent answering first.

Transfer your medical records and build a portable summary

Transferring medical records at 18 is one of the most concrete tasks on the list. Got Transition recommends preparing a medical summary as part of the transition plan and confirming that the transfer of records to the adult practice is complete. A useful portable summary captures your specific diagnosis and where in the gut it is active, past and current medications with any that failed or caused reactions, prior surgeries and hospitalizations, recent lab and imaging results, and vaccination status. Ask your pediatric office how it releases records, since many require a signed authorization once you are a legal adult. Keeping your own copy matters because the adult team may not automatically receive everything.

Switching from pediatric to adult gastroenterologist

Choosing an adult gastroenterologist ideally happens before you leave the pediatric practice, not after a problem arises. Ask your pediatric IBD team for referrals, since many maintain relationships with adult colleagues who see young patients and understand pediatric-onset disease. When you call to schedule, confirm the office accepts your insurance, ask how they handle biologic infusions or injections, and learn their process for urgent flares. Booking that first adult visit while you are still stable gives the new physician time to review your history and continue therapy without interruption. The American Academy of Pediatrics notes that structured transition support remains uncommon, with only about 15 percent of youth receiving help planning their move to adult care, so families often need to drive this step themselves.

Insurance changes when you turn 18 and again at 26

Insurance is where turning 18 gets financially real, and there are two milestones to plan around. Under federal rules, young adults can generally stay on a parent's health plan until they turn 26, which usually means Crohn's and colitis coverage continues without a break through your early twenties. The larger cliff arrives at 26, when you age off that plan and need your own coverage through a job, the Marketplace, or another option. Because IBD treatment can involve costly biologic drugs and specialty pharmacies, a lapse is risky. Learning your health insurance details early, including how prior authorizations and specialty medications are handled, is one of the self-management skills the Crohn's & Colitis Foundation flags as central to preparing for adult care.

Your pediatric to adult IBD transition checklist

Pulling the pieces together, an IBD transition checklist gives structure to what can feel like a long list of loose tasks. The Got Transition model organizes the handoff into six core elements, moving from a transition policy and readiness assessment through planning, transfer of care, and confirmation that the transfer is complete. For a family, that translates into a few grouped priorities:

• Own your history: assemble a portable medical summary, learn your medications and doses, and request your records.

• Own your care: practice leading appointments, choose an adult gastroenterologist, and book the first adult visit while stable.

• Own your coverage: understand your insurance now and map out what happens at age 26.

Working through these before symptoms force the issue keeps therapy continuous during a vulnerable stretch of life.

Turning 18 with IBD is a gradual transfer of ownership rather than a sudden cutoff, and starting years in advance makes it manageable. Because Crohn's disease most often develops in people between ages 20 and 29 and ulcerative colitis frequently appears between ages 15 and 30, young adulthood overlaps with the years when the disease demands the most attention. A young patient who can describe their condition, manage their medications, navigate appointments, and understand their insurance enters adult care ready to protect the remission they worked to reach.
