For most of your life, someone else ran the diabetes show. A pediatric team saw you every three months, a parent reordered supplies, and a nurse called when your numbers drifted. Then you turned 18, or 21, or went to college, and the system quietly handed you the keys.
If that transition felt more like being dropped than handed off, you are not alone. The years between 18 and 30 are when many people with type 1 diabetes fall out of regular care. Appointments slip, prescriptions lapse, and A1c creeps up, not because anyone stopped caring, but because adult life is busy and adult health care is built for people who already know how to navigate it.
This guide is for that moment: what changes when you move to an adult endocrinologist, what good care should look like, and how to find it.
Type 1 diabetes is not a children's disease
Type 1 diabetes is an autoimmune condition. The immune system destroys the insulin-producing beta cells in the pancreas, and without insulin the body cannot move glucose out of the blood and into the cells that need it. It is often diagnosed in childhood, but it can start at any age, and most people living with it are adults.
That matters because the problems change as you grow up. A 10-year-old's diabetes plan revolves around school, sports and growth spurts. A 25-year-old's revolves around long work days, alcohol, travel, dating, driving, pregnancy planning and paying for supplies. Your care should follow.
What changes when you move to adult care
You become the decision maker. Adult endocrinologists expect you to bring your data, ask questions and help set the plan. That is a good thing, but it can feel abrupt.
Visits get shorter in many practices. A typical adult clinic visit leaves little time to review two weeks of CGM data, adjust pump settings and talk about life. That gap is where many young adults disengage.
New screening starts to matter. Eye exams, kidney checks (urine albumin and kidney function), blood pressure, cholesterol and thyroid testing become routine. People with type 1 diabetes also have higher rates of other autoimmune conditions, such as Hashimoto's thyroiditis and celiac disease.
Insurance and logistics shift. Coverage changes, especially around age 26, can interrupt access to pumps, sensors and insulin at the worst possible time.
What good adult type 1 care looks like
Your technology should work for you. Continuous glucose monitors such as Dexcom and FreeStyle Libre, and automated insulin delivery systems (often called hybrid closed loop, such as Omnipod 5, Tandem Control-IQ and Medtronic 780G) have changed what is possible. A good endocrinologist reviews your sensor data at every visit, looks at time in range and patterns, not just A1c, and adjusts settings with you.
Your life is part of the plan. Night shifts, endurance training, a few drinks on a Friday, a long flight, a new relationship. Each one affects glucose, and each one deserves a practical strategy rather than a lecture.
Lows are taken seriously. Frequent or unnoticed hypoglycemia is dangerous, especially when driving. Adults should have a current glucagon prescription and a plan for the people around them.
Planning ahead for pregnancy. For women with type 1 diabetes, tight glucose control before conception lowers the risk of complications for mother and baby. Pregnancy should be planned with your endocrinologist, ideally months in advance.
Your mental health counts. Diabetes distress, the exhaustion of managing a condition 24 hours a day, is common and treatable. It deserves the same attention as your A1c.
You can reach your doctor between visits. Most real problems happen on a Tuesday night, not on appointment day. Being able to message your endocrinologist about a pump failure or a run of lows can prevent an urgent care visit.
Red flags that your current care is not working
No one has looked at your CGM or pump data in the last six months
Your prescriptions lapse because no one reaches out
You have had a severe low, or a hospital visit for diabetic ketoacidosis (DKA), in the past year
You have not had an eye exam or kidney test in more than a year
You leave appointments with no clear change to your plan
How we care for adults with type 1 diabetes
At Chia Endocrinology & Wellness in Wexford, I see adults with type 1 diabetes in person and by secure video across Pennsylvania and Ohio. I am a board-certified endocrinologist, and I spend time on what matters most: reviewing your CGM and pump data together, adjusting settings, and building a plan around how you actually live.
Visits are longer, and members can message me directly between appointments. If you are moving from pediatric care, or you have been out of regular diabetes care for a while, this is a good place to restart.
