Dear Doctor. Blonz: I focus on diet and exercise, but how much does my family’s medical history affect my risk of disease? – TP, Tulsa, Oklahoma
Dear TP: We all differ in our level of risk for developing various diseases and conditions, including osteoporosis, certain cancers, high blood pressure, Alzheimer’s disease, allergies, addiction and diabetes, and rare diseases. Finding a frequency of these conditions in your family suggests elements of your genetic heritage are involved.
Genetic research continues to provide information on predisposition to many diseases and urges us to be vigilant. There are several home DNA tests that can let you know where you are. In addition to providing information to help you keep track of your family tree, such tests can reveal whether you have genetic traits that are linked to disease risks. Programs can even suggest ways to adjust your diet and lifestyle to reduce these risks. A fun side benefit of these tests is that you can learn about some other genetic traits – such as a liking or dislike for cilantro; whether you can smell the tell-tale smell in the urine after eating asparagus; a propensity for male baldness; and whether you are more likely to have a ring finger that is longer or shorter than your index finger.
