The one page your child’s doctor wishes you brought
Nine in ten U.S. teens with type 2 diabetes had a relative with diabetes. Here is how to build a simple family health history, and what to ask the doctor once you have it.
At the next checkup, the nurse hands you a clipboard. Any family history of diabetes? Heart disease? High blood pressure? You check a box or two, guess at the rest, and hand it back. Nobody is sure whether it was Grandpa or Tío who had the heart attack, or how old he was.
That clipboard matters more than it looks. A family health history is one of the few free, no-needle tools a parent has for a child’s health. This post walks you through building one page you can hand your child’s doctor.
Why the doctor keeps asking
The National Library of Medicine explains it simply: families share genes, and often environments and habits too. Patterns among relatives can show who has a higher-than-usual chance of common problems like heart disease, high blood pressure, stroke, certain cancers and type 2 diabetes.
For children, diabetes is the big one. The National Institute of Diabetes and Digestive and Kidney Diseases lists a family history of diabetes as a risk factor for type 2 diabetes. It adds two that apply to kids: being born at a low birth weight, and a mother who had gestational diabetes while pregnant with that child. The American Academy of Pediatrics names the same things, a family member with the disease and a mother with diabetes during pregnancy.
How strong is the link? In the TODAY study, the largest national group of U.S. youth with type 2 diabetes, 89.4% of the 704 young people (ages 10–17, enrolled 2004–2009) had a family history of diabetes. Nine in ten.
Why this matters in Nueces County
Here, a lot of families will have something to write down. The 2025 Corpus Christi–Nueces County Community Health Assessment reports diagnosed diabetes in 15.5% of adults, compared with 13.4% in Texas and 10.8% nationally. High blood pressure sits at 33.1% of local adults, above Texas (30.8%). (Both figures are CDC PLACES estimates for 2022.)
That is not a verdict on your child. The NLM is clear that having relatives with a condition does not mean a person will definitely get it, and a child with no family history can still be at risk. A history does not predict the future. It tells the doctor where to look.
Who goes on the page
MedlinePlus suggests starting with close blood relatives: parents, brothers and sisters, grandparents, aunts and uncles, and cousins. For each person, try to learn:
- Their approximate age, or the age and cause of death if they have passed.
- Long-term conditions: diabetes, high blood pressure, heart disease, stroke, asthma, cancer.
- How old they were when it started. This is the detail most people skip.
- Problems with pregnancy, including diabetes during pregnancy.
- Where the family came from, and any health habits they are willing to share.
The age of onset is worth the extra phone call. MedlinePlus notes that risk is higher when more than one relative has a condition, or when someone developed it 10 to 20 years earlier than most people do. “Grandma got diabetes at 70” and “my brother got it at 32” tell a doctor very different things.
A one-page template you can copy
Draw this on a sheet of paper or in the notes app on your phone. Do one page for each side of the family.
| Relative | Condition(s) | Age it started | Living? / age and cause of death |
|---|---|---|---|
| Mom | e.g. diabetes in pregnancy | 28 | Living |
| Dad | |||
| Brothers and sisters | |||
| Grandparents (4) | |||
| Aunts and uncles | |||
| Your child | Birth weight, any conditions |
Leave blanks where you do not know. An honest “not sure” is more useful to a doctor than a guess.
How to gather it without making it awkward
MedlinePlus and the National Human Genome Research Institute both point to family gatherings as a natural time to ask. In fact, the U.S. Surgeon General’s Family History Initiative launched in 2004 at Thanksgiving for exactly that reason. A few ideas:
- Ask the family member who keeps track of everyone. Every family has one.
- Explain why: “The pediatrician asked, and I want to get it right for the kids.”
- Offer to share the finished page with everyone. It helps their children too.
- Obituaries and death certificates can fill in ages and causes for relatives who have passed.
Some relatives will not want to talk about their health, and that is their right. Take what they offer and thank them.
What to do with the page
Bring it to your child’s next well visit and ask one question: “Given this history, is there anything you would check sooner or watch more closely?” Let the doctor decide what, if anything, needs testing. Keep the page with your child’s shot records and update it when something changes.
And remember the other half of the story. Families share kitchens, schedules and habits, not only genes. That part you can change together, starting this week.

Not medical advice. Ignite His Glory is a community and faith organization, not a healthcare provider. We explain publicly available guidance so families can have better conversations with a doctor. Always talk with your child’s clinician before changing diet, exercise or any medication.
Ten weeks. One coach. No cost to your family.
Ignite Fit puts this into practice for children ages 8 to 17 in Corpus Christi — movement, a teaching kitchen and a family that learns alongside the child.
