Irritable Bowel Syndrome (IBS) and Polycystic Ovary Syndrome (PCOS) are two distinct conditions that can significantly impact a woman's health and quality of life. While seemingly unrelated, emerging research suggests a potential link between the two, with a notable overlap in symptoms and a higher prevalence of IBS among women with PCOS. Understanding this connection and adopting appropriate dietary and lifestyle strategies can offer much-needed relief and improve overall well-being.
Understanding IBS and PCOS
Irritable Bowel Syndrome (IBS): IBS is a functional gastrointestinal disorder, meaning the gut appears normal under a microscope, yet individuals experience real and disruptive symptoms. Affecting an estimated 10 to 15 percent of people in the United States, IBS is more common in those assigned female at birth. Symptoms include abdominal pain or discomfort, altered bowel function (diarrhea, constipation, or both), bloating, gas, and sometimes fatigue, anxiety, and depression.
Polycystic Ovary Syndrome (PCOS): PCOS is a complex hormonal disorder affecting 6 to 12 percent of women of reproductive age in the United States. It's characterized by an imbalance in reproductive hormones, often leading to irregular menstrual cycles, excess androgens (male hormones), and/or polycystic ovaries. PCOS can also cause a range of symptoms, including weight gain, acne, excessive hair growth (hirsutism), and fertility problems. Many symptoms relate to high hormone levels such as androgens and insulin. Up to 80% of people with PCOS are resistant to the effects of insulin and thus have more insulin in their blood to compensate. Insulin also increases testosterone levels. Having even slightly higher levels of testosterone can upset the balance of hormones in the body and lead to acne, excess hair and irregular periods.
The Connection Between IBS and PCOS
Several factors may contribute to the link between IBS and PCOS:
- Hormonal Imbalances: PCOS is characterized by excess levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which can disrupt ovulation and menstrual cycles. High levels of these hormones can also affect the digestive tract, delaying food movement and potentially leading to constipation. Estrogen and progesterone, two female sex hormones, may cause constipation by slowing down intestinal muscle contractions. These hormones fluctuate during menstruation, which can cause diarrhea. Female sex hormones also increase the perception of pain. Women are more likely to feel stomach cramps and discomfort due to bowel issues. Female sex hormones also increase your susceptibility to stress, which can lead to IBS symptoms.
- Inflammation: Studies suggest that PCOS causes chronic inflammation, which is also implicated in the development of IBS. Inflammation can affect the intestinal lining (mucosal inflammation) and the gut-brain axis (neuroinflammation).
- Gut Microbiome Imbalance: Women with PCOS often exhibit less diverse gut bacteria, potentially contributing to both PCOS and IBS symptoms. The gut microbiome plays a crucial role in overall health and immunity. Studies suggest an imbalance in gut bacteria may contribute to PCOS symptoms like insulin resistance and inflammation. Latest research in this field, show far-reaching implications of a dysfunctional microbiome. These include: poor immunity, IBS symptoms, development of disease and even effects on mood and mental health.
- Stress: Higher stress levels are often observed in women with PCOS, which can exacerbate IBS symptoms.
- Medication Use: Certain medications used to manage PCOS, such as metformin, can have gastrointestinal side effects that worsen IBS symptoms.
Diagnosis and Management
If you suspect you have both PCOS and IBS, it's crucial to consult with a healthcare professional for proper diagnosis and management. This may involve:

- Medical History and Physical Exam: Doctors will inquire about your medical history and conduct a physical exam to assess your symptoms.
- Blood Tests: Blood tests can help identify abnormal hormone levels indicative of PCOS and rule out other conditions.
- Ultrasound: An ultrasound can examine the ovaries for excess follicles, a characteristic feature of PCOS.
- Stool Test: A stool test can help detect blood or signs of infection in the stool, aiding in IBS diagnosis.
While there's no cure for either PCOS or IBS, treatment focuses on managing symptoms and improving quality of life. A holistic approach encompassing dietary changes, stress management, regular exercise, and, in some cases, medication is often the most effective.
Dietary Strategies
Diet plays a crucial role in managing both IBS and PCOS symptoms. Here are some dietary strategies to consider:
- Anti-Inflammatory Diet: Adopt an anti-inflammatory eating pattern emphasizing whole, nutrient-dense foods like fruits, vegetables, whole grains, legumes, nuts, seeds, and olive oil. This approach can improve body composition, hormone balance, menstrual cycle regularity, and glucose management.
- Low Glycemic Index (GI) Carbohydrates: Choose low GI carbohydrates and wholegrain foods to improve insulin levels and resistance, thereby reducing PCOS symptoms. Eating low GI foods is also linked with having more regular periods.
- High-Fiber Foods: Incorporate high-fiber foods to regulate blood glucose and insulin levels, decrease cholesterol levels, and improve liver health. High-fiber foods help regulate blood glucose and insulin levels, which are key pillars in PCOS management. Fiber also helps decrease cholesterol levels and improve liver health. Both of which are often compromised in individuals with PCOS.
- Omega-3 Fatty Acids: Include more omega-3 fats, found in oily fish, to help lower inflammation commonly seen in those with PCOS. Aim for one to two portions a week of oily fish.
- The Low-FODMAP Diet: Since the bowel symptoms of Endometriosis and PCOS overlap with those experienced in IBS, a low FODMAP diet may help relieve digestive discomfort. Consider following a low FODMAP diet, which restricts certain fermentable carbohydrates that can trigger digestive discomfort in individuals with IBS. FODMAPs are short-chain carbohydrates poorly absorbed by the small intestine. These fermentable sugars can be responsible for triggering digestive discomfort in those with IBS symptoms.
- FODMAPs is an acronym for foods that are difficult for most people to digest. FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols, which are groups of short chain carbohydrates, fibers and sugar alcohols that can cause GI distress. There are numerous foods in each of these categories ranging from gluten to beans to apples and onions.
- A low FODMAPs approach is an evidence-based food trial that can help up to 75% of IBS-sufferers get symptom relief.
- Identifying trigger foods can be difficult, as these are different for each person. Keeping a food diary of meals and ingredients along with symptoms, can help identify triggers. Eating a balanced plate which includes low GI or high fiber carbs, proteins, and fats can also be helpful.
- One approach that is more restrictive and not for everyone, especially anyone with or with a history of an eating disorder, is eliminating high FODMAPS foods for a short period of time (4 to 6 weeks) and slowly reintroducing them back in to check for symptoms. This break also helps the gut to rest.
Lifestyle Modifications
In addition to dietary changes, lifestyle modifications can significantly impact both IBS and PCOS:
- Regular Exercise: Being physically active has many known benefits, but the most relevant to PCOS is that it improves your body’s response to insulin. Types of exercise could include resistance or cardiovascular training, but even more gentle forms of movement like yoga or walking are beneficial. It’s important to find something that you enjoy and can fit into your lifestyle. Regular exercise improves your body's response to insulin and helps manage stress. Walking and yoga have been shown to be helpful for IBS. One study found that doing a one hour yoga class 3 times a week helped to lower testosterone levels by 29%!
- Stress Management: Practice stress-reducing techniques such as yoga, mindfulness, meditation, or spending time in nature.
- Adequate Sleep: Aim for 7-8 hours of quality sleep per night to support hormonal balance and reduce stress.
- Weight Management: If you're carrying extra weight, some weight loss may improve PCOS symptoms. However, insulin resistance, food cravings and over-eating can make weight loss with PCOS harder. Try to focus on what to include in your diet, rather than following a faddy diet and the ideas above is a good place to start.
Additional Considerations
- Prebiotics and Probiotics: Consider incorporating prebiotics and probiotics into your diet to support a healthy gut microbiome. Probiotics are live microorganisms, and when ingested, they provide good bacteria. Prebiotics are the food source for the good bacteria in our gut. Prebiotics and probiotics have been known to help with dysbiosis in the digestive tract, which may help with PCOS symptoms.
- Micronutrients: Address any potential micronutrient deficiencies, particularly in zinc, vitamin D, vitamin E, selenium, inositol, and chromium.
- Consult a Registered Dietitian: Work with a registered dietitian, especially one specializing in FODMAPs, to create a personalized dietary plan that meets your individual needs and addresses both IBS and PCOS symptoms. A Dietitian can perform a full patient assessment, including a symptom assessment and diet. A FODMAP dietitian will provide practical ways to help you fit the low FODMAP diet into your lifestyle. Ensuring that you still get all the nutrients you need from your food.
- Food Diary: Keeping a food diary of meals and ingredients along with symptoms, can help identify triggers. A good way to electronically track everything is in the mySymptoms Food Diary.
The Low FODMAP Diet: A Closer Look
The low FODMAP diet has gained recognition as a helpful strategy for managing IBS symptoms. FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols - short-chain carbohydrates that can be poorly absorbed in the small intestine, leading to fermentation and digestive distress.
Key Principles of the Low FODMAP Diet:
- Elimination Phase: Temporarily restrict high-FODMAP foods for 2-6 weeks to allow the gut to rest and symptoms to subside.
- Reintroduction Phase: Gradually reintroduce high-FODMAP foods one at a time to identify individual trigger foods and tolerance levels.
- Personalization: Develop a long-term eating plan that limits trigger foods while maintaining a varied and nutritious diet.
Benefits of the Low FODMAP Diet:
- Reduced bloating: Both PCOS and IBS can cause bloating.
- Improved gut health: By implementing the low FODMAP diet and identifying your triggers, this will be beneficial for overall health, immunity and a sense of wellbeing.
- Blood sugar management: PCOS can lead to insulin resistance.
Important Considerations:
- The initial elimination phase of the low FODMAP diet is meant to be short-term only.
- The low FODMAP diet can mean restricting certain food groups.
- Work with a FODMAP-specialized Dietitian to guide you through the elimination and reintroduction process.
- Learn about the low FODMAP diet, but don’t be too anxious about this complex diet.
- Plan meals and prep low FODMAP options to make following the diet easier.
Sample Low FODMAP Eating Plan for PCOS
- Breakfast: 2 eggs, avocado, 1 cup berries
- Lunch: (bowl) ¼ cup lentils, ½ cup quinoa, salad greens, ¼ avocado, salmon, tahini dressing
- Snack: Almonds, clementine
- Dinner: Chicken stir fry (chicken, avocado oil, green beans, carrots, kale, cashews, ¾ cup brown rice)
