Blood work & labs

Your doctor orders the tests. I help you understand what they mean for food, movement and daily life — and what to ask about next.

Why labs are part of the science byte

You can't coach around a low ferritin, an underactive thyroid or a creeping HbA1c if nobody has looked. Many of the symptoms people blame on age or stress — exhaustion, weight change, fog, low mood — have a marker that explains part of them.

Before a program starts I ask for recent results if you have them. If you don't, I'll give you a list of markers to discuss with your doctor. With results in hand, we build nutrition and movement around what your body actually needs.

What I do and don't do. I'm a coach, not a physician. I don't order tests, diagnose conditions or replace medical advice. I help you read your results, spot what's worth a conversation with your doctor, and adjust lifestyle factors within your doctor's guidance.

Markers I commonly review

A midlife baseline. Your doctor decides which are appropriate for you.

MarkerWhat it tells usWhy it matters at midlife
Thyroid (TSH, free T4, free T3)Thyroid functionFatigue, weight change, cold intolerance and low mood overlap heavily with perimenopause; thyroid issues are common and often missed.
Ferritin, iron, B12, folateIron and vitamin storesHeavy perimenopausal periods drain iron. Low levels explain a lot of "I'm just tired."
Vitamin DBone, immune and mood supportWidely low, especially in northern cities. Directly relevant to bone density after menopause and to muscle in men over 50.
Fasting glucose, HbA1c, fasting insulinBlood sugar control over monthsInsulin sensitivity drops as estrogen and testosterone fall. Catching a rise early is the whole game.
Lipid panel (LDL, HDL, triglycerides, ApoB if available)Cardiovascular riskHeart disease risk rises sharply after menopause; LDL often jumps within a few years of the last period.
hs-CRPInflammationA rough measure of systemic inflammation that food, sleep and movement all influence.
FSH, estradiol, progesteroneOvarian hormone statusUseful context, but they fluctuate so much in perimenopause that a single result can mislead. Symptoms matter more than one number.
Testosterone (total and free), SHBGAndrogen statusRelevant for men's energy, muscle and mood from the 40s onward, and sometimes for women too.
Cortisol (AM)Stress hormoneContext for sleep, energy and where weight is stored. Interpreted carefully — it's a noisy marker.
Liver and kidney panels, CBCGeneral health screenThe basics. Occasionally these explain symptoms nobody expected.
Bone density (DEXA)Bone strengthNot a blood test, but the one scan every post-menopausal woman and every man over 65 should ask about.

How we use the results

Results become inputs. Low vitamin D changes what we prioritize in food and daylight. A rising HbA1c moves the nutrition byte toward protein, fiber and meal timing, and the tech byte toward a two-week glucose monitor. Low ferritin plus heavy periods becomes a conversation with your doctor and an iron-aware food plan meanwhile.

Bring what you have

Recent results from your GP, gynecologist, urologist or an annual physical are all useful. I'll also give you a "questions to ask your doctor" checklist — it's a free download on the resources page.
