Importance of Knowing Your Family Medical History

A record of health information about an individual’s close relatives is known as a family medical history. A complete record contains information from at least three generations of relatives, including parents, sisters and brothers, uncle and aunts, nephews and nieces, cousins, grandparents, and children.
Families have numerous factors in common, including their lifestyle, environment, and genes. Together, those factors may determine medical conditions that may exist in your family. By observing disorders pattern among relatives, professional in the healthcare field can determine whether future generators, a person, or other family members may be at risk of developing a specific condition.
A good family medical history enables healthcare professional to identify individuals with a higher-than-usual likelihood of having some disorders, such as diabetes, certain cancers, stroke, high blood pressure, and heart disease. These disorders are influenced, to a large extent, by a combination of environmental conditions, lifestyle choices and genetic factors. Also, a family history can shed some light on the risk of rarer disorders caused by mutations, such as sickle cell disease and cystic fibrosis.
Although a family medical record can provide information about the likelihood of a person to develop a particular disorder, having relatives with certain medical conditions does not mean a person will certainly develop those conditions. An individual with no family history of a condition, on the other hand, may still be at risk of having that condition.
