Family Health History

Family History is Important to your Health
Most of us know that we can reduce our risk of disease by eating a healthy diet, getting enough exercise, and not smoking. But did you know that your family health history might be one of the strongest influences on your risk of developing cancer, diabetes, heart disease, or stroke? Even though you cannot change your genetic makeup, knowing your family health history can help you reduce your risk of developing health problems.

Family Health History and Your Risk for Disease

Family members share their genes, as well as their environment, lifestyles and habits. Everyone can recognize traits that run in their family, such as curly hair, dimples, leanness or athletic ability. Risks for diseases such as asthma, diabetes, cancer, and heart disease also run in families.

Everyone’s family health history of disease is different. The key features of a family health history that may increase risk are:

Diseases that occur at an earlier age than expected
(10 to 20 years before most people get the disease)
Disease in more than one close relative
Disease that does not usually affect a certain gender
(i.e., breast cancer in a male)
Certain combinations of diseases within a family
(for example, breast and ovarian cancer, or heart disease and diabetes)

If your family has one or more of these features, your family health history may hold important clues about your risk for disease.

The holidays are a perfect time to discuss this important topic with your family.

Family Health History and Managing Your Risk for Disease
People with a family health history of disease may have the most to gain from lifestyle changes and screening tests.

You can’t change your genes, but you can change unhealthy behaviors, such as smoking, not getting enough physical activity, and poor eating habits. In many cases, adopting a healthier lifestyle can reduce your risk for diseases that run in your family.

Screening tests (such as mammograms and colorectal cancer screening) can detect diseases like cancers at an early stage when they are most treatable. Screening tests can also detect disease risk factors like high cholesterol and high blood pressure, which can be treated to reduce the chances of getting disease.

Write down the information and share it with your health professional. Your health professional will do the following:

assess your disease risk based on your family health history and other risk factors
recommend lifestyle changes to help prevent disease
prescribe screening tests to detect disease early

If your health professional notices a pattern of disease in your family, it may be a sign of a disease that is passed on from generation to generation. Your health professional may refer you to a specialist who can help determine whether you have an inherited form of disease. Genetic testing may also help determine if you or your family members are at risk. Even with inherited forms of disease, steps can be taken to reduce your risk.

What if You Have No Family Health History?
Even if you don’t have a history of a particular health problem in your family, you could still be at risk. This is because:

your lifestyle, personal medical history, and other factors also influence your chances of getting a disease
you may be unaware of disease in some family members
you could have family members who died young, before they had a chance to develop chronic conditions such as cancer, diabetes, heart disease, or stroke

Being aware of your family health history is an important part of a lifelong wellness plan.
