What other sources of information may be beneficial?
You might want to consult family documents, such as existing family trees, baby books, old letters, obituaries or records from places of worship. Public records — birth certificates, marriage licenses and death certificates — are usually available in county record offices. If you or your family members maintain electronic personal health records, use them.
If you're adopted, ask your adoptive parents if they received any medical information about your biological parents at the time of your adoption. Adoption agencies also might have family medical information on file. If you were adopted through an open adoption process, you might be able to discuss your family's medical history directly with members of your biological family.
What information should be included in a family medical history?
If possible, your family medical history should include at least three generations. Compile information about your grandparents, parents, uncles, aunts, siblings, cousins, children, nieces, nephews and grandchildren. For each person, try to gather the following information:
- Date of birth
- Medical conditions
- Mental health conditions, including alcoholism or other substance abuse
- Pregnancy complications, including miscarriage, stillbirth, birth defects or infertility
- Age when each condition was diagnosed
- Lifestyle habits, including diet, exercise and tobacco use
- For deceased relatives, age at the time of death and cause of death
Pay special attention to conditions that develop earlier than usual, such as high blood pressure in early adulthood, or conditions that affect multiple relatives.
How should the information be compiled?
Once you've gathered information about your family, create a diagram that visually depicts the relationships among family members. Record medical information and other details about each person on your tree. If information about a disease or cause of death is unknown, don't guess at the answer. An incorrect guess can result in a poor interpretation of your medical history. Don't worry if some details are missing.
Give your doctor a copy of your family medical history and ask him or her to review it with you. Your doctor might ask you questions for clarification and can help you interpret the relevance of certain patterns in your medical history, including the need for preventive measures or screening tests. Going forward, update your family medical history every couple of years. Be sure to share updates with your doctor.
