Metformin is one of the most commonly prescribed medications for women with PCOS (and those with type 2 diabetes). It helps the body manage blood sugar levels and insulin more effectively. This can help mask many of the metabolic and hormonal symptoms of PCOS, like irregular periods, infertility, weight gain, fatigue, excess body/facial hair, and acne.
Metformin does this by activating an enzyme called AMP-activated protein kinase (AMPK). This is essentially your metabolism’s on-and-off switch, helping your body regulate fat storage and energy output. It also reduces insulin production in your liver and improves how the gut and muscles absorb sugar.
As metformin optimizes metabolic function, insulin sensitivity increases. Since insulin is a hormone, as it balances, other hormones follow—androgens and cortisol included. And as both systems balance out, the body no longer sees itself in “emergency mode.” With that, inflammation finally eases. As these root issues improve with metformin, symptom relief naturally follows.
If you’re a sister dealing with PCOS, this offer is enticing. One pill to relieve nearly all your symptoms? It sounds too good to be true! Well, in a way, it is—which is why many Cysters have made the choice to stop taking Metformin. If you fall into this category, you may now be dealing with a resurgence of PCOS symptoms, frustrated and confused. But here’s the thing: metformin withdrawal could be the culprit—but not in the way you think. I’m here to break it down today.
15 Metformin Withdrawal Symptoms PCOS
Though metformin can be really helpful for some, it’s important to understand that the medication only masks the problem. Metformin (or other prescription medications like Ozempic or spironolactone) doesn’t actually resolve the core problems of hormonal imbalance, insulin resistance, or inflammation. Plus, metformin comes with its own laundry list of unpleasant symptoms. (If you’re wondering, here’s a full list of metformin pros and cons.)
I’m a firm believer that every medication should have an exit plan. Staying on metformin forever to cover up symptoms probably won’t get you to your healing goals. It’ll just kick the can down the road. Instead, I recommend naturally managing PCOS for true symptom relief—no prescriptions required.
If you’re one of the thousands of Cysters transitioning off metformin and moving toward a more holistic healing plan, I’m here for you. I’ve packed The Cysterhood app with tons of useful resources, recipes, and routines to help you reverse PCOS and feel like yourself again.
But, as someone who was once on metformin, I know it can be difficult to discontinue the medication. So, to help make the process easier, I’ll walk you through what to expect when stopping metformin and share practical tips for navigating the transition smoothly.
Here’s what you should know:
Does Metformin Have Withdrawal Symptoms with PCOS?
Most people (including those with PCOS) don’t have withdrawal syndrome when they discontinue metformin. Unlike some medications, it doesn’t cause a physical dependency that leads to classic withdrawal symptoms. So, don’t expect side effects like headaches, sweating, anxiety, sleep disturbances, dizziness, or cravings for the medication itself when you stop taking metformin.
What Is Metformin Withdrawal?
Metformin withdrawal isn’t a true “withdrawal reaction.” Instead, it’s a sudden return of underlying PCOS issues that weren’t being managed outside of the medication. So if inflammation, insulin resistance, and hormonal imbalance were problems before taking metformin, they may return once you stop taking the medication.
This is especially likely if you didn’t make other lifestyle changes to address the root causes while on the prescription. In fact, for some Cysters, symptoms can feel even more intense after metformin. This can happen if relying on the drug inadvertently contributes to unhealthy habits, like poor nutrition, lack of exercise, and bad sleep.
If this sounds like you, it’s not your fault. Don’t carry any guilt with you! Many doctors who aren’t well-versed in PCOS have unintentionally sold Cysters a false bill of sale about what medications like metformin and birth control actually do – and what they don’t do. The important thing now is remembering that there is a better path forward. One that focuses on natural, holistic solutions that support real, lasting healing.
Here’s my essential guide to managing PCOS naturally.
What Are the Withdrawal Symptoms from Metformin with PCOS?
Fatigue
Without the support of metformin, unchecked insulin resistance can lead to big peaks and valleys in blood sugar. More specifically, unstable glucose levels can leave you feeling consistently tired and drained, even after rest.
Sugar Cravings and Increased Hunger
That lack of insulin regulation can also trigger stronger hunger signals and cravings. As a result, many women coming off metformin report increased hunger along with stronger cravings for sugar and carbohydrates.
Feeling Shaky or Lightheaded Between Meals
Blood sugar fluctuations can lead to shakiness, dizziness, and muscle weakness. This is especially prevalent between meals or when you haven’t eaten in a while.
Brain Fog or Difficulties Concentrating
Metabolic issues, like insulin resistance, can lead to chronic inflammation. Both can affect cognitive function and mental clarity, leading to brain fog and difficulties focusing.
Weight Gain
Moderate weight gain is pretty common after stopping metformin. High glucose levels and insulin resistance signal your body to store more fat while making it harder to burn energy efficiently.
Irregular or Missed Periods
Elevated insulin levels can affect other hormone levels as well. Specifically, excess insulin can signal your ovaries to produce more male sex hormones (androgens), which can influence period regularity.
Delayed Ovulation
Disruption of the menstrual cycle doesn’t just mean late or missed periods—it means delayed ovulation, too. Imbalances of key sex hormones can actually affect every stage of the menstrual cycle.
Worsening PMS Symptoms
These hormonal fluctuations can make premenstrual syndrome (PMS) more intense for those getting off metformin. Many report increased mood swings, bloating, cramps, or irritability right before their period.
Difficulty Getting Pregnant
Unpredictable ovulation, missed periods, and imbalances of sex hormones can make it really hard for Cysters to get pregnant after metformin. If this is you, here are some fertility tips from Dr. Felice Gersh and my personal pregnancy story.
Acne Flare-Ups or Oily Skin
High androgens stemming from insulin resistance can stimulate your sebaceous glands to produce more oil. The result? Greasy skin and lots of breakouts.
Facial Hair Growth
Hirsutism is common with high androgen levels. This is when unwanted hair grows on the chin, upper lip, jawline, and more.
Thinning Hair or Hair Loss
High androgen levels associated with insulin resistance can disrupt the normal hair growth cycle. Over time, this may lead to thinning hair along the scalp or increased hair shedding.
Nausea or Upset Stomach
Some women notice mild stomach discomfort after stopping metformin. As your body adjusts to changes in blood sugar and hormones, you might experience nausea or a general upset stomach.
Diarrhea
Changes in digestion can also happen while your body readjusts. This may show up as loose stools or more frequent trips to the bathroom for a short period of time.
Bloating
Hormonal shifts and digestive changes after metformin can sometimes lead to bloating and stomach pain. For help with this, here’s what to do about PCOS pain in the lower abdomen.
How to Deal with the Symptoms of Metformin Withdrawal
Focus on improving blood sugar balance.
The blood sugar-balancing effects of metformin are what provide the most symptom relief and weight-loss benefits. So, when you’re feeling side effects from discontinuing metformin, a lot of that comes from destabilized glucose levels.
To make the transition easier and support long-term healing, focus on regulating your blood sugar levels naturally. If possible, do this even before you stop taking metformin! That way, the transition isn’t so hard on your metabolism.
Here are some ways to improve insulin sensitivity and support more stable blood sugar:
- Adopt a gluten- and dairy-free anti-inflammatory diet.
- Eat balanced meals with protein, healthy fats, and lots of fiber.
- Use Crave Control Protein powder to hit your macros and fight cravings.
- Avoid sugary drinks, processed foods, and refined carbs.
- Eat meals at consistent times each day.
- Support gut health with fiber and fermented foods.
- Prioritize hydration by drinking water and electrolytes.
- Take insulin-sensitizing supplements like Berberine Advanced, Inositol Complete 40:1, and Meta Multivitamin.
Prioritize regular slow-weighted and meditative workouts.
Daily movement can have a huge impact on your metabolism and endocrine system. As your muscles use glucose for energy, exercise naturally improves insulin sensitivity. This effect on insulin has a domino effect, helping to balance other hormones like estrogen, progesterone, and testosterone.
If that wasn’t enough, exercise can also reduce inflammation and stress levels. All these benefits are super helpful for managing potential metformin withdrawal and holistic PCOS healing.
Just make sure you’re doing the right type of exercise. High-intensity workouts can actually have the opposite effect, raising stress levels and throwing hormones all out of whack. Instead, opt for slow-weighted workouts and meditative exercises.

Make a stress management plan to keep cortisol levels low.
Cortisol is your body’s stress hormone, which may sound unrelated to the effects of metformin. However, stress is actually completely intertwined with your blood sugar and hormone balance. High cortisol levels will increase insulin resistance and androgens, amplifying withdrawal side effects and PCOS symptoms.
As you transition off metformin and into a natural healing strategy, have a plan to better manage stress. As you transition off metformin and into a natural healing strategy, have a plan to better manage stress. Reduce your mental load, spend time outdoors, and make room for activities that help you relax. Gentle movement like walking or yoga, deep breathing exercises, meditation, and setting boundaries around work and responsibilities can all help keep cortisol levels in check.
Practice better sleep hygiene for better quality rest.
Sleep plays a huge role in blood sugar regulation and hormone balance. When you’re sleep deprived, your body becomes more insulin resistant, and cortisol levels rise. Over time, poor sleep can worsen cravings, fatigue, and other PCOS symptoms.
Aim for 7–9 hours of quality sleep each night and keep a consistent sleep schedule whenever possible. Create a relaxing bedtime routine, limit screen time before bed, and keep your bedroom cool and dark. Small habits like getting morning sunlight, avoiding caffeine late in the day, and winding down with reading can help improve sleep quality and support long-term hormone balance.
Here’s more on how to get better sleep with PCOS.
Monitor your symptoms and keep your doctor updated.
As we mentioned earlier, metformin doesn’t typically cause true withdrawal symptoms. However, it’s still important to keep your healthcare professional informed about any side effects you experience after stopping the medication. They can help make sure your symptoms aren’t something more serious and guide you through a safe, effective plan for managing PCOS after metformin.
What feels like metformin withdrawal is actually the return of unresolved PCOS symptoms.
Coming off metformin can feel intimidating at first, especially if symptoms start to return. But what feels like withdrawal is often just your body asking for deeper support. The good news is that real healing is possible when you address the root causes of PCOS instead of just masking symptoms.
By focusing on stabilizing blood sugar, lowering inflammation, and supporting hormone balance through simple habit changes, you can address the root causes of PCOS totally naturally. Thousands of women with PCOS have seen real improvements through holistic lifestyle changes, and you can too. Natural healing takes patience and consistency, but it’s absolutely possible—and it leads to stronger, more lasting results than relying on medication alone.
