Still PCOS (now called PMOS) without "cysts"

A plainspoken guide to what this pattern can mean, what is often missed, and what to ask next.

How to use this guide

Your type is which two — or all three — of the signs doctors check you have: periods off schedule, extra androgens, and the "string of pearls" look on an ultrasound. It's not a grade and it's not a verdict. Think of it as a shortcut to what's likely going on under the surface, what to keep an eye on, and which parts of the usual PCOS advice actually apply to you.

Two things worth knowing before you read:

Type B: Still PCOS without "cysts"

You have periods that don't run on schedule and signs of extra androgens, but your ovaries look normal on ultrasound. That's still PCOS. Diagnosis needs two of the three signs, and you have two. The "polycystic" in the name refers to follicles, not real cysts, and you don't need them to have the condition.

Under the surface, Type B behaves a lot like Type A. The hormone pattern is the same, and so is the tendency toward blood sugar trouble: studies consistently find Types A and B carrying the most metabolic risk. Everything in the Type A guide about insulin, cholesterol, and blood pressure applies to you too.

What's often missed

  • The diagnosis itself. A lot of people with Type B were told "your ultrasound is normal, so it's not PCOS." That's wrong under the criteria doctors use. If that happened to you, the two signs you do have are enough.
  • The follow-up. Because the ultrasound was normal, Type B sometimes gets treated as the "lighter" case and skips the metabolic checks. It shouldn't. The blood sugar and cholesterol screening below is the same as for Type A.
  • The uterine lining. Same issue as Type A: infrequent periods over years raise the risk of the lining thickening abnormally. Ask about a minimum schedule.

Medication notes

Same list as Type A, because the drivers are the same.

  • Metformin — for the blood sugar side; can lower B12 over time, so ask for a level.
  • The pill (combined) — for cycles and androgen symptoms. Not with St John's wort.
  • Spironolactone — for hair and acne, with reliable contraception; skip potassium supplements and "lite" salt.
  • Letrozole — first-line for ovulation when trying to conceive.
  • GLP-1s — for weight and blood sugar; ask about pill absorption around dose changes.

If you're trying to conceive: stop spironolactone and the pill first, and talk about letrozole. Your ovaries looking normal on ultrasound is neither good nor bad news for fertility — the issue is ovulation, not the ultrasound.

What to ask your doctor

  1. “My ultrasound was normal. Can you confirm my diagnosis is based on irregular cycles plus androgens, and that both were properly documented?”
  2. “Were my androgen labs done off the pill?”
  3. “Can we do a glucose tolerance test, and check cholesterol and blood pressure? Then repeat on a one-to-three-year schedule.”
  4. “How often do I need a period to protect my uterine lining?”
  5. “Is it worth repeating the ultrasound at some point, or does it not change anything? (Often it doesn't — but it's a fair question.)”
  6. “If relevant: What should change now if I want to get pregnant in the next year or two?”

Your stack is coming; save your results to hear first.

This guide is a starting point for a conversation with your doctor, not a substitute for one. Types are a research framework — they describe patterns across many people, and your own picture may not fit one neatly. Supplements aren't evaluated by the FDA to treat any condition. Talk to your doctor before starting or stopping anything, especially if you're pregnant, trying to conceive, or on medication.
