Foods to Avoid when taking Metformin for PCOS

Foods to Avoid when taking Metformin for PCOS

Polycystic Ovary Syndrome (PCOS) is a common hormonal disorder affecting women of reproductive age, and Metformin is often prescribed as part of its management. While Metformin is effective in improving insulin sensitivity and reducing symptoms of PCOS, it can sometimes lead to gastrointestinal (GI) side effects. However, making certain dietary adjustments can help minimize these discomforts. In this blog post, we'll explore the foods you should avoid when taking Metformin for PCOS to reduce the likelihood of experiencing GI side effects.

High-Sugar Foods and Beverages and PCOS

Avoid high sugar bevegage while taking Metformin for PCOS

Consuming foods and beverages high in sugar can exacerbate Metformin's GI side effects, such as nausea and diarrhea. These include:

  • Sugary drinks like sodas, fruit juices, and energy drinks
  • Candies, chocolates, and sweets
  • Pastries, cakes, and other sugary desserts

It's advisable to opt for low-sugar alternatives or natural sweeteners like stevia to satisfy your sweet cravings without aggravating Metformin's side effects.

Fatty and Fried Foods while taking Metformin

Fried Foods should be avoid with Metformin

Fatty and fried foods can be hard to digest and may increase the risk of experiencing GI discomfort when taking Metformin. Foods to limit or avoid include:

  • Fast food items like burgers, fries, and fried chicken
  • High-fat dairy products such as full-fat cheese, cream, and butter
  • Processed meats like sausages, bacon, and salami

Instead, choose lean protein sources and opt for cooking methods like grilling, baking, or steaming.

Artificial Sweeteners with Metformin

Some artificial sweeteners, such as sorbitol and mannitol, can cause diarrhea and bloating. These are commonly found in:

  • Sugar-free gum and candies
  • Diet sodas and other sugar-free beverages
  • Low-calorie or sugar-free packaged foods

Opt for natural sweeteners or small amounts of sugar to avoid these side effects.

Avoiding Alcohol

Alcohol may affect Metformin

Alcohol can interact with Metformin and increase the risk of lactic acidosis, a rare but serious side effect. It can also contribute to GI upset. It's best to limit or avoid alcohol consumption while taking Metformin.


Managing your diet when taking Metformin for PCOS can help reduce the likelihood of experiencing gastrointestinal side effects. By avoiding or limiting high-sugar foods, fatty and fried foods, excessive fiber, artificial sweeteners, and alcohol, you can minimize discomfort and support your overall treatment plan for PCOS. Always consult with your healthcare provider or a registered dietitian for personalized dietary advice tailored to your specific needs and health goals.
