PMOS (Formerly PCOS) Nutrition in Portland, Oregon

New name, same you. And finally, a name that reflects what's really going on: hormones and metabolism, not "cysts."

Chelsie Moore is a functional medicine clinician and integrative dietitian nutritionist in Portland, OR, who helps women with PMOS (polyendocrine metabolic ovarian syndrome, formerly called PCOS) through personalized, root-cause nutrition. Her work addresses insulin resistance, irregular cycles, energy, skin, mood and weight. She sees clients in person in Portland and virtually.

Maybe you were diagnosed years ago, told to "lose weight" and handed birth control, and never got much else. Or maybe you're just now putting the pieces together. Either way, there is so much more we can do, and food is one of the most powerful tools we have.

Does This Sound Familiar?

PMOS looks different for every woman, which is part of why it's so often missed or misunderstood. You might be dealing with:

  • Irregular, infrequent or absent periods

  • Weight gain, especially around your middle, that doesn't respond to eating less and exercising more

  • Intense sugar or carb cravings, and energy crashes after meals

  • Acne along the jaw and chin

  • Unwanted hair growth on the face or body, or thinning hair on your scalp

  • Fatigue, brain fog, anxiety or low mood

  • Trouble getting pregnant

  • Being told your blood sugar or cholesterol is "borderline"

  • A long history of diets that left you feeling like the problem was you

It isn't you. PMOS involves real hormonal and metabolic drivers, and when we support those, symptoms often shift in ways willpower never could.


What Is PMOS, and Why Did PCOS Get a New Name?

Polyendocrine metabolic ovarian syndrome (PMOS) is the new name for polycystic ovary syndrome (PCOS). It affects about 1 in 8 women, more than 170 million worldwide. The name was announced in May 2026 in The Lancet after a global consensus process involving patients, clinicians and 56 organizations.

The old name focused on ovarian "cysts," which aren't actually cysts, and which many women with the condition don't have. That framing led to missed diagnoses and care that often stopped at the ovaries. The new name leads with what research shows sits at the heart of the condition:

  • Polyendocrine: multiple hormones are involved, including insulin, androgens (like testosterone) and reproductive hormones

  • Metabolic: insulin resistance and metabolic health are central, with lifelong effects on blood sugar, heart health and weight

  • Ovarian: it still affects ovulation, cycles and fertility

The change is being phased in over about three years, so you'll see both names for a while. Your diagnosis hasn't changed, but the way it's understood has. That's good news, because the metabolic side is exactly where nutrition can make the biggest difference.

A Root-Cause Nutrition Approach to PMOS

There's no single "PCOS diet," and restrictive plans often backfire, especially for women who've spent years dieting. My approach is personalized, evidence-informed and built to last. We focus on:

  • Insulin and blood sugar: meal composition, protein, fiber and timing to steady blood sugar and improve insulin sensitivity, which often eases cravings, energy crashes and cycle irregularity

  • Androgens and skin: nutrition and lifestyle strategies that support healthier androgen levels, with benefits for acne and hair

  • Inflammation: anti-inflammatory eating patterns that support metabolic and hormone health

  • Nutrient status: checking and correcting common gaps, such as vitamin D, B12 (especially if you take metformin), iron and magnesium

  • Stress, sleep and movement: cortisol, sleep and muscle-building movement all shape insulin sensitivity

  • Your life stage: PMOS needs change across fertility planning, postpartum and perimenopause

Your plan may include personalized nutrition, targeted lab testing, realistic behavior-change strategies, and pharmaceutical-grade, third-party tested supplements from one of our trusted partners. Food should feel nourishing, not like punishment. I work alongside your OB-GYN, endocrinologist or fertility team, not in place of them.

I'm Chelsie Moore, a functional medicine clinician and integrative dietitian nutritionist, and the founder of Moore Integrative Health in Portland, Oregon. I work primarily with women on blood sugar regulation, hormone health, perimenopause, fatigue, mood and sleep, and autoimmune concerns.

I hold a master's degree, two years of clinical residency, a certification in behavior change from the Yale School of Public Health, and I'm in on-going continuing education with Aviva Romm, MD with a pending certification in Integrative & Functional Women's Health. That behavior-change background shapes everything I do. A plan is only useful if it fits your real life, so we build one you can actually follow.

You deserve care that's current, compassionate and actually useful.

PMOS & PCOS Nutrition FAQs

Is PMOS the same as PCOS?

Yes. Polyendocrine metabolic ovarian syndrome (PMOS) is the new name for polycystic ovary syndrome (PCOS), announced in May 2026. The condition is the same. The new name better reflects its hormonal and metabolic nature.

What is the best diet for PMOS or PCOS?

There's no single best diet. Research supports eating patterns that steady blood sugar and improve insulin sensitivity, with adequate protein, plenty of fiber, healthy fats and minimally processed foods. The right plan depends on your symptoms, labs, preferences and goals.

Can you have PMOS/PCOS without insulin resistance or without being overweight?

Yes. Many women with PMOS are in a smaller body, and insulin resistance can be present regardless of weight. Nutrition support is about metabolic and hormone health, not only weight.

Can nutrition help with PMOS symptoms?

For many women, yes. Improving blood sugar balance and insulin sensitivity can support more regular cycles, steadier energy, fewer cravings and improvements in skin. Nutrition works alongside medical care, including medications like metformin or hormonal treatments when appropriate.

Can PMOS affect me after my fertility years?

Yes. That's part of why the name now includes "metabolic." PMOS is associated with higher long-term risk of type 2 diabetes and heart disease, so supporting your metabolic health matters at every life stage, including perimenopause.

Do you offer virtual appointments?

Yes. I see clients in person in Portland, Oregon, and virtually.

Do you take insurance?

Moore Integrative Health is an out-of-network provider. I can provide a superbill you may submit for possible reimbursement, and HSA/FSA funds can often be used.

A New Name, and a Better Way Forward

The new name finally acknowledges what so many women have felt all along: this is a whole-body hormonal and metabolic condition, and it deserves whole-body care. With the right nutrition support, many women feel steadier energy, calmer cravings, more predictable cycles, and a lot more peace with food.
