One body. Four arms.
The wiring behind
your symptoms.
PMOS doesn’t show up as a single symptom. It shows up as a system. The Atlas is the map of where it lives in the body and how the loops between organs reinforce each other. Start with a symptom you recognize. The wiring underneath will start to make sense.
Tap a symptom. See where it lives.
Each symptom traces back to a specific set of organs and the loop they’re caught in. The Pattern report tells you which arms are loudest in your body. The Atlas tells you what’s actually happening underneath.

Pick a symptom you recognize. The organs involved will light up, and the loop they’re part of will draw across the body. Tap another symptom to see how the system shifts.
Tap a symptom on the left to see which organs are involved, which loop they’re part of, and what the evidence currently holds.
Four arms. Four organs. One body holding all of them.
PMOS is described in current evidence as four mechanism arms that reinforce each other. Each arm anchors to a specific organ, produces a recognizable cluster of signs, and connects to the others through coupled loops. Most presentations carry more than one arm at a time.
The pancreas releases more insulin to do the same job. That extra insulin reaches the ovaries and nudges androgen production. It also tells the liver to make less SHBG, leaving more free testosterone in circulation. Present across body sizes, including lean PMOS.
Most of the extra androgens in PMOS come from the ovary. Insulin amplifies this, which is why androgenic arms often sit on top of a metabolic layer. Androgens travel through circulation and meet receptors at the skin, the hair follicles, and the scalp. The visible signs follow.
Chronic low-grade inflammation is well-evidenced in PMOS. NF-κB activation in immune cells correlates with insulin resistance and androgen production. Whether inflammation is upstream of the metabolic and androgenic arms or downstream of them is not yet settled. The loops reinforce each other either way.
A second androgen source. The adrenal glands produce DHEAS in roughly 20 to 30 percent of PMOS presentations, often with regular cycles and a leaner build. This pattern is heritable, not stress-driven. The popular framing of “Adrenal PCOS” as a cortisol condition is not supported by the current evidence base.
How the cascade keeps itself going.
PMOS is not a list of symptoms that happen to co-occur. It is a small number of coupled loops between organs that reinforce each other. These four are the most evidenced. None of them is established as the single upstream cause. Each one feeds the others.
The pancreas makes more insulin to do the same job. That extra insulin reaches the ovaries and nudges them to make more androgens. The androgens make insulin resistance worse. The loop perpetuates itself, which is why 3pm crashes and jawline acne so often show up in the same body.
Ovarian androgens travel through circulation and meet androgen-sensitive tissues. Most visibly the jawline, chin, and hair follicles. The acne, the hair changes, the texture shifts: the skin is reading what the hormones are doing.
The liver makes SHBG, a protein that decides how much testosterone is freely active. Insulin lowers SHBG. Lower SHBG means more free testosterone, even when the total looks normal. This is one reason “fine” lab work can sit next to a body that does not feel fine.
The adrenal glands make DHEAS, a separate androgen that travels through circulation alongside ovarian-source testosterone. This route is most visible in lean and post-hormonal PMOS, confirmed by DHEAS lab work, and appears to be heritable. It is not a stress condition, and it does not respond to stress-reduction protocols.
The map is universal.
The pattern is yours.
The Atlas is the same for everyone. Same organs, same loops, same wiring. What’s different from body to body is which arms are loudest. That’s what the Pattern report figures out: which of the four arms is doing the most work in your presentation, what to ask a clinician about, and what to watch for between visits.
