By symptom
Erectile dysfunction.
ED is the canary. The body is telling you something about vascular and hormonal health.
What’s actually going on
How I think about this.
Erectile dysfunction is one of the most underread symptoms in conventional men's health. The reflex is to prescribe a PDE5 inhibitor and move on. That fixes the symptom, sometimes, but misses the diagnostic gift.
ED is a downstream signal from the vascular system, the hormonal system, the metabolic system, and the nervous system, working together or not. Erectile tissue is some of the most flow-sensitive tissue in the body. When ApoB is high, insulin is resistant, testosterone is low, blood pressure is elevated, or inflammation is up, this tissue is often the first place it shows. A 45-year-old man with new ED has a different cardiovascular risk profile than a 45-year-old man without it, regardless of his cholesterol panel.
The right read is to treat ED as the diagnostic event it is. Run the full cardiometabolic and hormonal workup, identify what is actually driving the presentation, and treat the system. The PDE5 prescription can still be part of the plan. It is the band-aid, not the strategy.
The physician’s lens
How I read this in practice.
I read ED across cardiovascular and hormonal axes together. ApoB, Lp(a), hsCRP, fasting insulin, HbA1c. Total and free testosterone with SHBG, estradiol, the full thyroid panel, prolactin when warranted. Blood pressure measured properly across multiple days. Sleep quality and architecture. The medication list, because more prescriptions affect erectile function than most patients realize. The metabolomic panel adds the nutrient and oxidative-stress story underneath all of it.

Where this symptom comes from.
Most cases touch more than one. Open each area to read the biology underneath.

Mitochondria.
Mitochondria produce the ATP that powers every function in your body. Directly assessable. Directly correctable.

Metabolomics.
Urinary organic acids read the upstream patterns of energy production, neurotransmitter balance, detoxification, and recovery.

Chronobiology.
Every hormone, immune function, and metabolic process runs on a circadian schedule. The disruption is measurable, and the consequences are systemic.

What I’d test first
The data that explains it.
ED needs the cardiovascular panel, the full hormone read with binding proteins, and the metabolic axis in one draw. Treating it as anything less is treating the symptom and missing the diagnostic information your body is giving you.
Blood work
Cardiometabolic blood panels
Reads ApoB, Lp(a), fasting insulin, and the inflammation markers. The vascular story underneath the symptom.
Read the panelBlood work
Hormone health blood panels
Reads testosterone with SHBG, the full thyroid axis, and adrenal output. The hormonal story that drives the rest.

Moves worth making before testing.
These are the levers I’d pull while we set up the workup. Most of them produce real signal inside two weeks.
- Lift heavy two to three times a week. Resistance training improves both the hormonal and vascular drivers.
- Sleep seven to nine hours with a fixed wake time. Testosterone is made overnight; sleep loss collapses it.
- Cut alcohol for two weeks. The vascular response shows up quickly.
- Bring your medication list to the call. Several common prescriptions affect erectile function in ways the prescribing physician often doesn't mention.
If two weeks of the basics doesn’t move the needle, that is exactly the kind of presentation a Precision Call exists for. Your biology is telling you something the lifestyle layer cannot fix on its own.

Mitochondrial health and aging.
Aging is, to a meaningful degree, mitochondrial. The decline is not inevitable on a fixed trajectory. The interventions that slow it are the same ones that improve your function right now.

Fasting and mitochondrial biogenesis.
Fasting drives mitochondrial biogenesis through a specific signaling pathway. Done well, it improves metabolic flexibility. Done badly, it undermines the same biology it is supposed to support.

Mitochondria and brain health.
The brain is your most energy-hungry organ. When mitochondrial function slows, cognition slows with it. Most brain symptoms in modern adults have a mitochondrial layer worth reading.

Something else on your mind?
Fatigue and low energy
When the tank stays low no matter how much you sleep.
Brain fog
The lights are on but the signal feels weak.
Poor sleep
Either you can't fall asleep, or you can't stay asleep.
Digestive issues
Bloating, irregularity, sensitivities that keep widening.
Mood and stress
Patience runs short, recovery from stress takes longer.
Hormonal imbalance
Energy, sleep, libido, and weight stop responding to the basics.
Perimenopause
The years when the body's hormonal rhythm changes, before the period stops.
Low libido
Desire that used to be reliable is gone or muted. Both sexes, both directions.
Hair loss
Thinning, shedding, or texture changes that didn't used to happen.
Erectile dysfunction
ED is the canary. The body is telling you something about vascular and hormonal health.
Weight loss resistance
You eat well, you train, the scale doesn't move. Something deeper is in the way.
High cholesterol concern
Your last lab flagged it. You want a second opinion before you take a statin.
High blood pressure concern
The reading came back elevated. You want the full picture before you start a prescription.
Insomnia
You can't get to sleep. You can't stay asleep. Or both.
Athletic recovery problems
You train hard. You don't bounce back. Something physiological is in the way.
Headaches and migraines
Recurring headache patterns the standard workup hasn't solved.
Joint pain
Pain in one joint is often a local problem. Pain that travels, or pain in multiple joints, is usually a systemic one.
Anxiety
Some anxiety is psychological. Much of what shows up in clinic is biological with a psychological face.
Acne and skin issues
The skin is rarely the problem. It is the most visible report on what is happening one layer down.
Thyroid symptoms
Cold all the time. Hair shedding. Sluggish mornings. A 'fine' TSH that explains none of it.
PMS and cycle issues
A difficult cycle is often a window into how your body handles hormones across the rest of the month.
Food cravings
Cravings are biology pulling for what it needs, often dressed up as what it can get easily.
Chronic allergies
New or worsening allergies in adulthood usually point to a barrier and an immune tone, not a specific allergen.
