GLP-1 research has focused on weight, not PCOS. So a monthly symptom log is a useful record of whether your PCOS is responding. On the first of each month, rate ten symptoms and measure your waist. Bring the trend to your clinician.
Why weight matters, and what it can’t tell you
Semaglutide and tirzepatide slow gastric emptying (how fast food leaves your stomach). They also act on the brain circuits that control appetite, and both help your body release insulin. Tirzepatide acts on a second hormone, called GIP.
Keep one caveat in mind. The large weight-loss studies enrolled people with obesity rather than PCOS, and they measured pounds, not acne or cycles. Insulin resistance sits at the center of PCOS, and weight loss reliably improves it. So there’s a good reason to expect these medicines to help. But nobody has measured how much your androgen symptoms (like acne and extra hair) will improve, or how fast. That gap is exactly why you track.
What to track each month
Rate how much each one bothers you, from 0 (not a problem) to 10 (the worst it’s been):
- Acne (especially along your jawline)
- Extra hair growth (chin, upper lip, jawline)
- Hair thinning on your scalp
- Irregular or missing periods
- Bloating
- Low mood and anxiety
- Poor sleep
- Low energy
- Low sex drive
- Brain fog
For periods, also write down the dates your bleeding started this month.
Add one real measurement: your waist, measured at the same spot each time.
Why a monthly log helps
Symptoms and lab tests tell you different things, and your clinician uses both. A lab test like testosterone or fasting insulin shows one moment in time. A monthly chart shows how you feel over many months. If your acne slowly drifts from 8 to 5, you won’t notice it day to day. On paper, you can see it. Bring the chart to your visits so your clinician can read it alongside your labs.
Track nausea too
Nausea is the most common side effect, and it clusters during dose escalation. Slower gastric emptying is part of the reason.
That’s why titration (raising the dose step by step) starts low and climbs slowly. For the Wegovy (semaglutide) injection, the label starts at 0.25 mg weekly and steps up about every 4 weeks (0.25 → 0.5 → 1.0 → 1.7 → 2.4 mg). It goes slower if side effects are rough. Score your nausea alongside your other symptoms. If it isn’t fading while your dose holds steady, talk to your clinician about titration. Don’t just quit. A US-licensed clinician reviews every case and can slow the climb.
Protect the muscle underneath
Not all of the weight you lose is fat. Fast weight loss takes some lean mass (muscle and other non-fat tissue) along with fat. We don’t know much yet about the long-term effects on strength and function. Treat this as a known risk with an unknown ceiling.
The standard countermeasure is resistance training plus about 1.2–1.6 g of protein per kg of body weight each day. Your waist measurement helps here. It adds a second view next to the scale, which also counts muscle you’d rather keep.
If you stop, it comes back
Before-and-after photos leave this part out. When people stop a GLP-1, much of the weight usually comes back.
For PCOS this cuts twice. If weight is what’s helping your symptoms, the symptoms follow the weight back up. Talk with your clinician about a long-term plan before you stop.
What a GLP-1 won’t fix
Be honest about the limits. These medicines work on weight and insulin, but they don’t lower androgens directly. If jawline acne and extra hair growth are your biggest problems, the right tool is often an anti-androgen. That’s a medicine that blocks male-type hormones. Spironolactone pills are one. Clinicians sometimes use them alongside a GLP-1, but Zappy doesn’t prescribe them, so you’d ask your own doctor. Spironolactone can harm a developing baby, so it needs reliable birth control. Your monthly chart shows which symptoms are getting better on their own, and which need a second medicine.
The simplest format, and the open question
Use a two-column note in your phone. Put the date at the top and your scores down the left side. It takes five minutes on the first of each month. Bring it to your visit. If you don’t have a clinician yet, start here.
Here’s what would change this advice. No large trial has tested whether GLP-1s improve PCOS symptoms, like ovulation and high androgens, apart from the weight they take off. None has tested whether any gains hold once the medicine stops. Until that trial runs, your monthly log is the data.
