You started your GLP-1 journey to lose weight, feel better, and take control of your health. But then your period decided to go completely rogue. Early, late, missing altogether, or suddenly throwing you back into PMS hell? Yep, welcome to the period on GLP-1s chaos club.
And before you panic: no, you’re not broken. You’re not imagining it. And you’re definitely not alone.
In this post, I’ll walk you through exactly why your period on GLP-1s might be acting up, what’s normal, what’s not, and most importantly, how to feel more like yourself again. Think of this as your no-fluff, real-life guide to navigating cycle drama while still smashing your goals.
So pop the kettle on, and let’s get you sorted.
1. GLP-1s Can Cause Period Changes (Here’s Why)
First things first: GLP-1 medications like Wegovy or Zepbound don’t directly cause period problems, but they can trigger a ripple effect through your hormones.
Rapid weight loss, reduced calorie intake, and body fat changes can all impact oestrogen and progesterone, making your cycle act up.
Plus, Zepbound side effects like nausea, digestive changes, or feeling frustrated can add even more stress to the mix, which we all know hormones love to react to.
If your sleep is also suffering (because let’s face it, insomnia makes everything worse), check out GLP-1 Insomnia 101: Why You Can’t Sleep and What to Do About It for real-life fixes.

2. Irregular Cycles Are Common – But Usually Temporary
A lot of women experience:
- Late or early periods
- Missed periods (especially with rapid fat loss)
- Heavier or lighter bleeding
- Weird PMS symptoms or none at all
It’s unsettling, but for most, these changes are temporary as your body adjusts to your GLP1 before and after transformation.
The key is to monitor, not panic.
If this rollercoaster is messing with your confidence or sense of self, I highly recommend Losing Your Identity on GLP-1s? How to Cope When Food Was Your Emotional Anchor, it’s a must-read for the emotional side of this journey.

3. When It’s Time to Call Your GP
Most period changes on GLP-1s are harmless, but there are definitely times you should reach out for medical advice:
- No periods for several months (and not just because of weight loss)
- Very heavy bleeding
- Severe pain
- Unexpected spotting for weeks
Better safe than sorry, right? Your health always comes first.

4. Eat for Hormone Balance (Yes, Even When You’re Not Hungry)
The tricky bit? GLP-1s can absolutely crush your appetite.
But skipping meals or under-eating can worsen hormonal imbalance, mess with blood sugar, and contribute to more feeling hungry or feeling nauseous episodes later on.
Prioritise:
- Protein-rich snacks (even if small)
- Healthy fats (avocado, nuts, olive oil)
- Fibre for constipation relief
- Hydration with an electrolyte drink or herbal teas

5. Move Gently When You Can
Exercise can help balance hormones, boost natural energy, and reduce PMS symptoms, but only if you’re not overdoing it.
Some days, a gentle walk or some stretching is enough. Others, you might fancy something a bit more energetic. Listen to your body.

6. Support Your Emotional Health Too
Let’s be real: when your period is all over the place and you’re adjusting to a major lifestyle change, it can do a number on your mood and self-esteem.
You might find yourself:
- Tearful or low
- Missing the comfort of old habits
- Struggling with body image
This is 100% normal, but it’s also 100% worth addressing. Try journaling, therapy, wellness habits, or even small pep talks to yourself. Little things add up.

7. Your Body Image Might Shift Too (And That’s OK)
You’d think losing weight would magically make you love your body, right? Except… sometimes it doesn’t.
Hormonal changes, period drama, loose skin, or shifting identity can all trigger body image wobbles.
It doesn’t mean you’re failing. It just means you’re human.
