Generations of Health: Lisa Boyd, PA, Discusses the Power of Family Medical History

Beyond shared memories and sentimental items, families pass down a genetic blueprint that can significantly influence your long-term health. While family medical history contains important information that is critical for preventive healthcare, taking time to record this information and share it with your provider is a step that many people overlook.

Lisa Boyd, Physician Assistant with CaroMont Family Medicine in Dallas, explains your family health history is an important tool, revealing patterns of disease dictated by genetics. Documenting these patterns is a proactive way to understand how your family story can shape your future wellness. 

What Is Family Medical History? 

“Family medical history is a record of the health conditions and diseases that have affected your biological relatives across generations,” explains Boyd.  “It tracks conditions and diseases across generations, focusing on parents, siblings and children. For a more comprehensive overview, it can also include details from grandparents, aunts, uncles and half-siblings.” 

This information matters because many common conditions, like heart disease, stroke, type 2 diabetes, certain cancers, stroke and mental health disorders, often run in families. When a condition appears in multiple relatives or if someone is diagnosed at an unusually young age, it could mean that you could face a higher risk. 

Why It Matters for Your Health 

According to Boyd, understanding why family medical history matters starts with recognizing how deeply genetics shape our health. 

“While lifestyle choices like diet, exercise and sleep play a significant role in overall wellness, they do not tell the whole story. Your DNA can quietly influence your risk for a wide range of conditions.” 

Here are several reasons Boyd says it matters: 

It helps predict risk before symptoms appear. Genetic predispositions often develop silently. For example, if a parent had a heart attack in their 40s, you and your provider gain a critical window to monitor cholesterol levels, blood pressure and other cardiovascular markers years before a problem might be detected. 

It guides smarter screening schedules. Standard screening guidelines are designed for the average person. If your family history places you at a higher risk, your provider might suggest getting checked sooner or more frequent screenings. For instance, women with a strong family history of breast cancer may begin mammograms early or seek genetic counseling to evaluate breast cancer gene mutations. 

It informs lifestyle decisions. Knowing your health risks can be a motivator for preventive behavior. Research shows that individuals who are aware of higher genetic risk are more likely to adopt heart-healthy diets, exercise regularly and avoid smoking. These choices can reduce the likelihood of developing hereditary conditions. 

It benefits your entire family. When one family member learns of a genetic risk, that information becomes important for siblings, children and other relatives. A single conversation can set a chain of preventive action in motion across an entire family. 

Common Conditions with Hereditary Links 

While any condition can have a genetic component, Boyd notes that the following are among the most strongly associated with family history: 

Cardiovascular disease — including heart attack, heart failure and high blood pressure
Type 2 diabetes
Certain cancers — particularly breast, ovarian, colon and prostate cancers
Stroke
High cholesterol — including familial hypercholesterolemia
Mental health conditions — such as depression, bipolar disorder and schizophrenia
Osteoporosis
Alzheimer's disease and other dementias 

How to Start the Conversation 

Gathering family health history does not require a medical degree; it requires a conversation. Boyd recommends these steps to get started: 

Ask relatives. Family gatherings are natural opportunities to ask parents and grandparents about the conditions they have been diagnosed with, the age of diagnosis and how those conditions were treated. Specify by asking about heart disease, cancer, diabetes and other major conditions by name. 

Review family records. Death certificates, obituaries and old medical records can provide valuable information about conditions that affected passed relatives. These documents tend to list cause of death or long-term illnesses that family members may not have discussed openly with others.  

Use a structured tool. There are free, web-based tools that can help individuals record and organize family health information in a format that can be shared with a provider. 

Share it with your care team. Once compiled, bring your family health history to your next appointment. Medical providers are trained to interpret this information and use it to personalize your care plan, which may include earlier screenings or specific diagnosis tests.  

Update it regularly. Family health history is not a one-time task. New diagnoses among relatives should prompt an update to your records and a conversation with your doctor to discuss how these changes might affect you.  

A Note on Genetic Testing 

Not everyone will need to pursue genetic testing, but for some patients it can be a valuable step. 

“For individuals with a significant family history of certain conditions, particularly hereditary cancers or early-onset cardiovascular disease, genetic testing and formal counseling may be appropriate. A genetic counselor can help interpret test results, clarify risk levels and outline options for monitoring or risk reduction,” explains Boyd. 

A positive result does not mean a condition is inevitable. However, for the right candidates, it provides an additional layer of information that can be life changing. 

The Bottom Line 

According to Boyd, “Medicine has made remarkable advances in treating diseases. But preventing disease before it starts remains the most effective strategy of all, and it begins with knowing your story.” 

Your family medical history is an important tool. Collecting it, preserving it and sharing it with your healthcare provider is one of the best steps you can take for your long-term health and the health of the people you love.
