By symptom
PMS and cycle issues.
A difficult cycle is often a window into how your body handles hormones across the rest of the month.
What’s actually going on
How I think about this.
Severe PMS, irregular cycles, and the cluster of symptoms around the menstrual phase usually trace to a few cellular themes: estrogen metabolism backed up because methylation or detox capacity is slow, progesterone running short because the upstream stress system has taken priority, and the gut microbiome failing to recycle estrogens cleanly. The cycle is the report. The upstream metabolism is the substrate.
This is the unifying pattern across chronic hormonal symptoms. PMS, perimenopause, low libido, hair shedding, and the broader cycle of complaints share the same upstream biology — the same cellular themes I read across the rest of HOMe. Different surface presentation, same underlying machinery.
The symptoms travel together because the biology does.
The physician’s lens
How I read this in practice.
A full hormone panel timed to the right cycle phase, with SHBG. Methylation markers because estrogen detox runs through it. Cortisol curve. Sometimes a gut panel if the estrobolome is plausibly involved. The pattern I find most is a slow-detoxing estrogen with a flat or reversed cortisol curve, often paired with sub-optimal progesterone in the luteal phase.

Epigenetics.
The methylation cycle is the dial your environment turns. I read where it is stuck.

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

The data that explains it.
Difficult cycles get the full hormone read first, then a metabolomics panel to see if methylation is the bottleneck on estrogen clearance. That combination explains most of what standard testing misses.
Blood work
Full hormone panel timed to the cycle
Total and free hormones with SHBG, timed to the right phase. The standard 'day 3' draw misses most of the picture.

Metabolomix+
Reads the methylation cycle that drives estrogen detoxification. The bottleneck that explains a lot of difficult cycles and gets missed entirely on standard hormone testing.

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.
- Track your cycle and symptoms in one app for two months. The pattern is usually clearer than any single lab can tell you.
- Cover the cycle nutrients: magnesium glycinate 200 to 400 mg at bedtime, B-complex with methylated forms in the morning, and iron only if your ferritin warrants it.
- Reduce alcohol in the luteal phase specifically. The liver is busy enough clearing hormones in that window without adding to the load.
- Cut caffeine after noon. Cortisol rhythm and progesterone are tightly linked in the luteal phase.
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.

Epigenetic clocks: what they measure, and what they do not.
Epigenetic age tests have become a wellness category. They produce a single number that feels meaningful and is mostly not clinically useful. Methylation function is the better read.

Epigenetics and cancer.
Most cancer is at least partly an epigenetic disease. The marks that go wrong are modifiable for years before they produce a tumor, and that is the window where lifestyle medicine earns its keep.

The link between toxins and your epigenome.
Environmental toxins damage the epigenome through specific mechanisms. Most of the load is reducible, and reducing it is one of the higher-leverage interventions for the methylation cycle.

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.
