Polycystic Ovary Syndrome (PCOS) and Inflammatory Bowel Disease (IBD) are two conditions that can significantly affect a woman’s health, but many may not realize that there is a potential connection between the two. While they are distinct in their nature, the relationship between PCOS and IBD may be more intricate than previously thought. Living with both makes for a complicated patient journey and is not talked about enough.
This week on Lights, Camera, Crohn’s we look at these conditions, how they influence one another, and hear from several women in the chronic illness community who experience both.
What is Polycystic Ovary Syndrome (PCOS)?
If you’re reading this, chances are you are aware of what IBD is, but PCOS may be more of a mystery to you. PCOS is a hormonal disorder that affects the ovaries, typically during the reproductive years. It’s characterized by irregular periods, excess androgen levels (leading to symptoms like acne, excessive hair growth on parts of the body where hair is normally minimal, scalp thinning), and the presence of multiple small cysts in the ovaries. PCOS is linked to insulin resistance, obesity, and an increased risk of developing type 2 diabetes, heart disease, and endometrial cancer and impacts 1 in 10 women who are childbearing age.

The precise cause of PCOS is still not fully understood, but genetic factors and lifestyle choices (such as diet and exercise) play a significant role.
The Shared Link: Inflammation
Both PCOS and IBD are associated with chronic inflammation. This is a key factor that may connect the two conditions.
Chronic Low-Grade Inflammation in PCOS
Research has shown that women with PCOS often have increased levels of inflammatory markers, such as C-reactive protein (CRP). This chronic low-grade inflammation can affect the entire body and is linked to metabolic dysfunctions like insulin resistance and obesity, both of which are common in PCOS. Inflammation in PCOS can also exacerbate other symptoms, such as ovarian dysfunction and difficulty managing weight.
Inflammation in IBD
On the other hand, IBD is fundamentally a disease of chronic inflammation. The immune system mistakenly attacks the lining of the digestive tract, leading to the symptoms of Crohn’s disease or ulcerative colitis. This ongoing inflammation can lead to gut permeability issues, nutritional deficiencies, and an altered gut microbiome. The inflammatory process in IBD is often more severe and widespread than in PCOS, but the principle of chronic, low-grade inflammation links the two conditions.

How Might Inflammation Link IBD and PCOS?
Though PCOS primarily affects the reproductive system and IBD affects the gastrointestinal system, both conditions share inflammation as a common underlying feature. Inflammation in one part of the body can exacerbate the other condition, making both difficult to manage at one time.
Here are a few ways in which inflammation might connect these two diseases:
Gut Microbiome Imbalance: Both IBD and PCOS have been shown to be influenced by imbalances in the gut microbiome. In IBD, the gut bacteria are disrupted, contributing to inflammation and disease progression. Emerging research suggests that women with PCOS also exhibit gut dysbiosis, which could worsen the inflammatory profile in the body. This imbalance may be a link that exacerbates both conditions, potentially influencing the development and progression of each.
Immune System Dysfunction: Both PCOS and IBD involve immune system dysfunction. In PCOS, the immune system may not properly regulate inflammation, contributing to insulin resistance and ovarian dysfunction. Similarly, in IBD, the immune system is dysregulated, resulting in chronic inflammation in the GI tract. A common immune pathway may contribute to the co-occurrence of these conditions in some individuals.
Hormonal Imbalances: Inflammation in PCOS can lead to hormonal imbalances that impact not only the reproductive system but also other systems in the body. Conversely, chronic inflammation in IBD may affect hormone levels, potentially exacerbating PCOS symptoms. For example, inflammatory cytokines may interfere with the normal balance of estrogen and progesterone, further complicating reproductive health.

Metabolic Dysfunction: Both PCOS and IBD are associated with metabolic issues, such as insulin resistance. Insulin resistance often goes hand-in-hand with chronic low-grade inflammation in both conditions, and this can make the management of both diseases more challenging. Insulin resistance can worsen inflammation, and inflammation can increase the likelihood of developing insulin resistance, creating a vicious cycle.
Medication Overlap: Some medications used to treat IBD, such as corticosteroids, can also exacerbate symptoms of PCOS, especially in terms of weight gain, insulin resistance, and hormonal imbalance. Conversely, treatments for PCOS, such as oral contraceptives and anti-androgen drugs, may have side effects that impact gut health, potentially influencing the course of IBD.
Managing the Dual Diagnosis
For those dealing with both PCOS and IBD, managing these two conditions simultaneously can be a delicate balancing act. Treatment plans need to address both the hormonal imbalances of PCOS and the inflammatory components of IBD.
Anti-inflammatory Diet: A diet rich in anti-inflammatory foods, such as fruits, vegetables, whole grains, and omega-3 fatty acids, may help reduce inflammation in both the gut and the reproductive system. A diet low in processed foods and sugar can also improve insulin sensitivity, which is crucial for managing PCOS.

Probiotics and Gut Health: Since both PCOS and IBD involve gut health disturbances, introducing probiotics or focusing on gut-healing strategies could help improve the balance of beneficial bacteria and reduce overall inflammation. However, the use of probiotics should be carefully monitored in IBD patients, as some may have adverse reactions during flare-ups. This is a conversation to have with your GI, as there are many differing opinions.
Medications and Monitoring: Medications for IBD (such as anti-inflammatory drugs or immunosuppressants) should be balanced with treatments for PCOS. A healthcare provider may consider the impact of one treatment on the other, as certain drugs could worsen either condition.
Physical Activity and Stress Management: Exercise can help with both insulin sensitivity and inflammation. Regular physical activity helps control weight and can reduce inflammatory markers in the body. Additionally, managing stress through mindfulness or relaxation techniques can also reduce inflammation and improve overall well-being.

The Patient Experience: Read Firsthand Accounts from Women with IBD and PCOS
When researching articles, one of my favorite parts of the writing process is to connect with patients who live the reality of the subject matter. Having the patient voice—people who are willing to share their firsthand experience to help others is priceless. Here is what women with both IBD and PCOS shared with me:
Kayla: “I am curious how many women with IBD also have PCOS because both my sister and I have it. I am getting put on Letrozole in a few weeks to helpfully get me to ovulate. I also have super high AMH which makes sense if I have PCOS, but it’s extremely high so I assume that also means a lot of eggs which also is the same for my sister. It’s crazy because my sister and I have led quite different lifestyles, but our health conditions have been nearly identical! I’m hoping to join the PIANO study soon after this round of medications.”
Sam: “Both PCOS and IBD affect my body and cause inflammation. It can be really tiring to deal with both. Also, there isn’t a cure for either one. Getting pregnant with both was interesting. I had to be in remission with my Crohn’s and then deal with trying to get pregnant which was difficult because of my PCOS. Family planning is extremely stressful with both conditions. I will say that an IUD and being on a GLP1 and infliximab infusions have helped keep my inflammation under control. I also feel like both are invisible diseases and people just dismiss them.”
Stephanie: “I was diagnosed with PCOS after coming off birth control for the first time in six years when I was 22. I was diagnosed with ulcerative colitis at age 26, nine months after having my first child. I never had any symptoms of uc prior to pregnancy and childbirth. My doctors say there is no correlation between both, but something that has been super interesting to me and my husband is the weight aspect…as you know with IBD there are many periods of time when you’re either using the bathroom 10+ times a day or even afraid to eat because of unknown outcomes, which causes many IBD patients to be underweight. But I’m the opposite. I gain weight during those periods and have a very hard time keeping the weight off with both diagnoses, which I chalk up to the PCOS causing insulin resistance (PCOS is often referred to as diabetes of the ovaries)…even though my labs don’t always show insulin resistance. It’s been extremely hard finding doctors who talk about other ways to help my PCOS without birth control.”
Stephanie also takes Metformin. She says both diagnoses come with their own challenges, but the PCOS diagnosis causes her more frustration since most of the suggestions are just to “lose weight” or take hormones to mask the symptoms of the disease. She is excited to see where the research on this topic and learn more about how the co-morbidities coincide between both diseases.

Jami: “I have IBD, diagnosed after four years of struggling through university (both my twin sister and I have Crohn’s disease). I had a major flare in 2015 and after a year of struggling I had surgery to remove my colon. I have an ileostomy and have had every surgery for Crohn’s since. Rectum removed. Stoma repairs, hernia repairs, fistulas, abscesses. I surprisingly got pregnant easily with my first daughter in 2019 after testing to ensure my surgeries did not disrupt my ability to conceive, but in 2021 I started to struggle to conceive and found out I had PCOS. I went to a fertility clinic to help to conceive my second child, and did not need IVF. Instead, I was given hormones and injections to help me ovulate properly and then I was on progesterone to help maintain the pregnancy for three months. If I’m being honest, I feel the C-vid vaccine screwed with my hormones. I don’t regret getting the vaccine as I’m immunocompromised from my biologic, but it was after the vaccines that my hormones were messed up and I started to have pain with my menstrual cycles (terrible cramping and awful breast pain before and during…which I never had before).”

Lindsey: “Crohn’s and PCOS here! I didn’t get diagnosed with PCOS until 2024 after trying to conceive for a couple of years. My only symptom is irregular cycles and multiple follicles on ultrasounds, so the diagnosis came as a shock to me.”
Gabby: “Living with Crohn’s is already a full-time job, but being diagnosed with PCOS added another complex layer. Both conditions affect my hormones, digestion, and inflammation—and often, managing one feels like it’s aggravating the other. PCOS makes it harder to control symptoms during Crohn’s flare-ups, and vice versa. I’ve learned to be incredible mindful of my diet, avoiding gluten and inflammatory foods to reduce triggers for both conditions. As a Latinx woman, one of the most frustrating things has been finding a way to manage my symptoms without feelings like I have to give up the foods that connect me to my culture. Traditional Cuban and Dominican dishes are rarely considered in medical diets or nutrition plans, and I’ve often felt overlooked in conversations about what’s “safe” to eat. But even with careful planning it’s not always enough.”

Gabby went on to say one of her biggest ongoing challenges is keeping her hormones balanced, especially during periods of high stress, something that often happens during a Crohn’s flare. She says stress tends to amplify both conditions, causing a domino effect of symptoms that can be physically and emotionally draining. Some days, she feels like she’s chasing balance that’s always out of reach.
Maddie: “My uc diagnosis came December 2012 when I was 14, wasn’t 8th grade such a fun year! I was put on mesalamine for the uc and birth control and spironolactone for my PCOS and didn’t have a second thought about either for 8.5 years, until I was 22 and my uc flared in June 2021. After the flare settled in July 2023, I stopped birth control a couple of months later to prepare to try to conceive after the six-month clearance. Stopping HBC didn’t impact my UC at all thankfully, which was a worry. We started TTC in April 2024 expecting it to take a while due to PCOS, but with a regular cycle, we conceived on the third cycle of trying in June 2024. We experienced a missed miscarriage where the baby stopped growing at 8 weeks, but we found out when I was supposed to be 10 weeks. After the miscarriage and D&C, I had a flare that lasted 4 months plus a 3-month waiting period before trying to conceive again.”
Maddie is thankful she was able to manage the flare with a course of budesonide. She did not need to switch maintenance medications.
“PCOS and uc are intertwined in this TTC journey, as PCOS unfortunately carries a higher miscarriage risk. Now that we know my body likely responds to loss and perhaps a full-term postpartum as well with a flare, it makes it much scarier of the risks of repeated losses and flares, and the worries of those make me worried about pregnancy-safe drug options, as well as the dangers of repeated/chronic inflammation on future health and cancer risks, and the worries of never being able to have a live birth or our ideal family size.”
Jenny: “Advocating for yourself is the first step towards healing, regardless of an individual’s situation. For years, I was told my Crohn’s disease and symptoms of PCOS were unrelated. It was a journey of perseverance towards confirming a diagnosis of PCOS and validation that the two are related. Trust your intuition, speak up, and never settle for answers that don’t feel right. Sometimes, the right doctors are the ones who truly listen—don’t be afraid to change your path until you find the care you deserve.

Jenny says it wasn’t until she had a female GI and a female gynecologist that she felt heard and understood. She says making that shift was pivotal in how she lived, improved her confidence, and her understanding of self-advocacy.
Final Thoughts
The relationship between IBD and PCOS is complex, but there are notable overlaps, especially in terms of chronic inflammation, immune system dysfunction, and metabolic disturbances. People with both conditions may face unique challenges, but understanding these shared pathways can help tailor treatments that address the root causes of inflammation and hormonal imbalances. Collaboration between healthcare providers across different specialties, such as gynecology, gastroenterology, and endocrinology, is essential to ensure comprehensive care for individuals managing both IBD and PCOS.

By recognizing these connections, we can better manage these conditions and improve the quality of life for those affected. While research appears to be limited regarding IBD and PCOS, there seemed to be a lot more discussion regarding Irritable Bowel Syndrome (IBS) and PCOS. I hope this article makes you feel seen, less alone, and empowered to discuss any health challenges that you may be experiencing but unsure of.
