#124 - AMA #15: Real-world case studies—metabolic dysregulation, low testosterone, menopause, and more
Peter Attia, joined by Bob Kaplan, delves into real-world case studies in this AMA episode, expanding on his lab analysis framework. They discuss interpreting diagnostic measures for metabolic dysregulation, low testosterone, menopause, hypothyroidism, elevated uric acid, and the critical role of comprehensive family history.

Omega Quant Test
This test assesses the amount of EPA and DHA (omega-3 fatty acids) in red blood cell membranes. It's used to evaluate dietary intake of fish or the effectiveness of omega-3 supplementation.
4 Questions Answered
Generally, no. In most cases, patients are encouraged to continue their supplements, and tests may be postponed if they've run out, to ensure the labs reflect the impact of the intervention. The key is knowing how long it takes for a supplement or drug to show an effect.
For mother, father, both sets of grandparents, all aunts, uncles, and siblings, inquire about cardiovascular disease (medications, stroke, heart attack), dementia, cancer, and metabolic diseases like diabetes. It's crucial to also understand the context of any findings, such as lifestyle factors like smoking.
While genetic data can offer some insights, family history provides a much richer and more practical understanding of inherited predispositions to diseases like cancer, dementia, and cardiovascular disease, especially when contextualized with lifestyle factors.
The OGTT, especially with frequent sampling of both glucose and insulin, is used to gain deeper insights into insulin sensitivity and metabolic health beyond what simple fasting blood glucose or A1c can provide. It's considered a crucial, though cumbersome, diagnostic tool.
9 Actionable Insights
1. Consult Healthcare Professionals
Do not use the information from this podcast as a substitute for professional medical advice, diagnosis, or treatment. Always consult your healthcare professionals for any medical conditions you have, as this podcast is for general informational purposes only and does not constitute medical advice.
2. Gather Detailed Family History
Collect extensive family history information for your mother, father, both sets of grandparents, all aunts, uncles, and siblings, focusing on cardiovascular disease (blood pressure, cholesterol, stroke, heart attack), dementia, cancer, and metabolic disease (diabetes). This provides far more insight than genetic data like 23andMe and helps identify patterns and genetic predispositions.
3. Contextualize Family Health History
When gathering family history, always ask ‘second order questions’ to understand the context of health events (e.g., if a relative with cancer was a heavy smoker, or if a relative with an early heart attack had other risk factors like alcoholism or heavy smoking). This prevents misinterpreting genetic predispositions when lifestyle factors were significant contributors.
4. Prepare Family History Template
If seeking medical advice, prepare a detailed family history template in advance of your first meeting with a doctor, as gathering this information requires significant time and effort, often involving many phone calls and research into deceased relatives. This ensures you can provide comprehensive data for a thorough assessment.
5. Continue Supplements Before Labs
Unless specifically instructed to stop, continue taking your supplements as usual before scheduled lab tests. Doctors often want to track biomarkers while you are on supplements, and will postpone tests if you’ve run out or forgotten to take them, to avoid misleading results.
6. Know Intervention Effect Timeline
Be aware of the time it takes for an intervention (whether a supplement or medication) to show its full effect on biomarkers. Testing too soon can lead to misinterpretations, such as thinking a supplement isn’t working or isn’t dosed high enough, when it simply hasn’t had enough time to assimilate.
7. Interpret Labs with Family History
Use detailed family history to interpret the severity and implications of lab findings, such as elevated LP(a). A strong family history of early cardiovascular events combined with elevated LP(a) warrants aggressive intervention, whereas the same elevated LP(a) with no family history of early events might suggest a less aggressive approach is acceptable.
8. Labs Inform Further Questions
View initial lab tests not as definitive answers, but as starting points that often lead to more questions and require further investigation beyond the initial set of results. This detective-like approach helps uncover deeper insights into your health.
9. Consider OGTT with Insulin
Consider undergoing an Oral Glucose Tolerance Test (OGTT) with frequent sampling of both glucose and insulin, as it provides a much deeper insight into insulin sensitivity and metabolic health compared to just fasting blood glucose or glucose-only OGTTs, despite being a more cumbersome test.
3 Key Quotes
This stuff doesn't mean jack compared to your family history.
Peter Attia
The more you know these things, the better. And it's also important to understand context.

You'd have to be a freak of nature to have that information at hand.

1 Protocols
Comprehensive Family History Information Gathering
Peter Attia- For mother, father, both sets of grandparents, all aunts and uncles, and siblings, gather all knowable information.
- Inquire about cardiovascular disease, including medication for blood pressure/cholesterol, history of stroke, chest pain, or heart attack.
- Inquire about dementia.
- Inquire about cancer.
- Inquire about metabolic disease, such as diabetes.
- Understand the context of any findings, e.g., if cancer was linked to heavy smoking, or a heart attack was linked to alcoholism/smoking, or how Lp(a) levels correlate with age of cardiovascular events.
