Polycystic Ovarian Syndrome (or “PCOS” as it is commonly referred to) is one of the most prevalent endocrine conditions that affects women and a common referral we see in our Dietitian practice.   

The primary characteristic of PCOS is sex hormone imbalance which results in altered functionality of the female reproductive system. The origin of PCOS and why it develops is unknown, however it has been associated with genetic influences 

PCOS can be associated with various health conditions such as diabetes, weight concerns, heart conditions, and metabolic syndrome. Unfortunately, many women are not officially diagnosed with PCOS and can struggle to manage their symptoms.   


PCOS hormone imbalance


Researchers have discovered that women who are diagnosed with PCOS exhibit higher levels of male androgens (sex hormones) than typical female levels. Normally, female sex hormones instruct the body to release an egg from the ovaries monthly that will travel throughout the reproductive system and either become fertilized or be shed at the end of every month.  

However, in women with PCOS, lower levels of female hormones may cause impartial release of an egg from the ovaries, potentially causing ovarian cysts to develop. These ovarian cysts produce the higher levels of male androgens that are characteristic of PCOS and lead to various symptoms. While not all women who have PCOS have cysts, there is a significantly greater chance of cysts with this condition.   


Symptoms of polycystic ovarian syndrome


PCOS has a variety of symptoms that can change and develop over time.   


Here are the most commonly reported symptoms:

  • Irregular menstrual periods 
  • Infertility  
  • Weight gain (including body composition and weight distribution changes) 
  • Ovarian cysts 
  • Excess body hair (hirsutism) 
  • Skin tags or changes in skin appearance  
  • Thinning or balding hair  
  • Acne and increased oily skin  
  • Insulin resistance 



Diagnosis and treatment of PCOS


Prior to treatment, PCOS must be diagnosed by your healthcare provider. It is estimated that up to 75% of women who have PCOS go undiagnosed as a result of overlapping symptoms with other conditions and lack of condition knowledge.

In order to be diagnosed, your physician or health care provider will go through a series of blood tests and ultrasounds to determine any ovarian cysts and levels of androgens in your body. Once PCOS is confirmed, you can begin various treatments and lifestyle changes that can help manage your symptoms.  


Associated conditions with PCOS


PCOS can be associated with an increased risk of a variety of health conditions.  Diabetes, weight concerns, heart conditions, and metabolic syndrome have been linked with PCOS.  


Diabetes and insulin resistance:


Insulin resistance and diabetes is one of the major symptoms and associated conditions with PCOS. It is reported that over 50% of women who have PCOS are diagnosed with type II diabetes prior to their 40th birthday. As a result, managing diabetes can be a major component of living with PCOS.

Individuals with type II diabetes produce insulin, a hormone used to manage blood glucose levels, however their body’s cells are unresponsive and therefore struggle to manage blood sugar. Insulin resistance is the beginning indicator of developing type II diabetes.  


Having diabetes increases your risk of developing other associated conditions, such as heart and stoke complications, weight concerns, and metabolic syndrome. Through proper treatment, daily management, and development of healthier behaviours, diabetes can be successfully managed for many years.

Weight concerns:


Weight gain and issues managing weight are key symptoms of PCOS. Due to the increase in male hormone production (androgens) that occurs with PCOS, many women will experience weight gain in areas of their body where typically males gain weight, such as their abdominal area. While the entire connection between PCOS and weight gain is unclear, having either of these conditions can increase the risk of developing the other 


Another reason why weight gain can occur is due to the insulin resistance or diabetes that can develop alongside PCOS. When blood sugar is unable to be managed properly by the body, it can lead to weight gain.

There are many nutrition and lifestyle changes that can be made to help manage weight concerns.  Talking with your doctor and a Registered Dietitian that specializes in emotional eating and weight concerns about how to achieve your personal best weight 


These articles may be of interest to those looking for weight management: 


Heart conditions:


Women with PCOS are at increased risk of developing heart conditions and experiencing heart health issues. Researchers have found that there is a two time higher risk of having a heart attack or stroke if you have PCOS. There is also an increased risk of heart issues if there is any previous episodes or hereditary conditions affecting the heart.  


Regular exercise and a healthy diet can positively influence your heart health and reduce risk of future complications. Consuming heart healthy foods can benefit your overall health and reduce your risk of heart disease.

Metabolic syndrome:


Metabolic syndrome is the combination of multiple noncommunicable disease, such as those discussed above and can also include hypertension and atherogenic dyslipidemia, a condition where there are increased levels of triglycerides throughout your blood. It is diagnosed using multiple methods of measurement, including body metrics, blood tests, and personal health history.  


Metabolic syndrome increases your risk of developing health conditions that can have a substantial impact on your overall well-being. Many of our clients find this diagnosis can be very overwhelming and difficult to know how to manage multiple conditions. However, there are lifestyle changes that you can make with the help of your doctor and a Registered Dietitian to reduce your risk for health conditions and manage associated symptoms. Contact us for help. 



Lifestyle changes and healthy food choices for PCOS


Each of the previously discussed conditions has unique treatments and management options, however there are commonalities between each condition that can help. 


Limit ultra-processed foods: 


Ultra-processed foods can contain high levels of salt, sugar, and fat and lower levels of essential vitamins and minerals. While each of these components plays a necessary role in your diet, over-consumption can lead to increased blood pressure, weight gain, and cholesterol levels. 


While all foods can fit and soulful foods chosen for taste and enjoyment are important for sustainability and social fun, being mindful of the quantity of pop, potato chips, candy, fast food and desserts is important for long term health and PCOS management.  A diet that includes whole grains, fruits and vegetables, heart healthy fats and lean protein sources can help balance your diet.  As part of this article series on nutrition for PCOS stay tuned for additional articles that will dive deeper on healthy eating for PCOS.  Subscribe to our free weekly newsletter here so you can be sure to receive notification about these upcoming articles and more healthy eating content and tasty recipes from our Dietitian team:  Subscribe to our weekly nutrition newsletter here. 



Elevate your physical activity: 


Regular physical activity helps your body in numerous ways. It strengthens your heart, muscles, lungs, and mental perseverance, all while improving your overall health. As well, regular physical activity can help you sleep better and remain rested and increase your muscle mass which elevates your metabolic rate (the rate your body burns calories). 


Being active does not mean you need to exhaust your body every day, but instead can include walking, yoga/stretching, and daily outdoor activities with your friends and family. Adults should be aim for 150 minutes of moderate to vigorous physical activity per week. Women with PCOS can also benefit from strength training to increase their overall muscle mass.  There are numerous online resources through social media and YouTube that provide free and accessible workouts for your favourite type of activity or work with a certified personal trainer for a customized plan. 


Regular sleep:

Dedicating time to ensuring you get enough sleep can be difficult, especially when managing families, careers, and various activities. Adults should be getting 7-9 hours of sleep every single night.. Eliminating screen time and taking the proper steps to relaxation before bed can help you fall and stay asleep throughout the night.  


Benefits of proper sleep go far beyond feeling energized the next day, but also include reduced stress, weight management, lowered risk of mortality, reduced disease risk, and an overall better quality of life.

Success stories

"I am a psychologist in private practice and it is very important to me that my clients have the best care with other health care professionals. For that reason Health Stand Nutrition is my only source for exceptional Dietitians. Andrea and her team provide highly knowledgeable, compassionate, and real world support to my clients who require assistance with food lifestyle. I trust my clients to them and you would be in excellent hands making them part of your health care team."
Adele Fox, Psychologist
“This is the first time I feel satisfied; my cravings have diminished dramatically and I have a whole new relationship with food. I am eating guilt-free for the first time in my life. My energy has also dramatically increased and I feel great!
Rhonda Jenkins, Nutrition Counseling Client
“The Dieticians at Health Stand Nutrition help you to take action on the science behind eating well by making it practical, understandable, and fun. Their office is cozy and not at all clinical or intimidating. I felt like I was sitting down with a really smart, caring friend who wanted to help me make the best choices for my lifestyle and food preferences. They really are the best in the business.”
Marty Avery, Nutrition Counseling Client
“I have come to think of the program as a one stop shopping excursion for everything one needs to know about creating a joyous relationship with food and our bodies. In a single word, the course has gifted me with freedom from the punishing rigidity of disordered eating, old stories that never were true, and body dysmorphia that did nothing but make me lose sight of a body that has done everything I've asked, despite my careless dismissal of her needs. Now when I look in the mirror I find myself shifting from harsh criticism to gentle gratitude.”
Lynn Haley, Pursuit of Healthiness Online Course Participant
“I spent 3 hours when first diagnosed with type 2 diabetes. I learned more from my Dietitian about food in those 3 hours than I had learned in all the years of my life. I also love the newsletter, there is always something to learn.”
Peter Whitehead, Nutrition Counseling Client
“I didn’t realize how strong my “diet mentality” was, and all the rules I had in my head about food. I was in a cycle of reward/punish/binge/cringe. I booked with your business very reluctantly, on the repeated advice of my doctor, to get my slowly rising cholesterol levels in check. I thought I knew everything about food, and my behaviour with food, but I was definitely re-schooled. My weight is creeping down, I feel good about my diet, exercise, body image, and lifestyle.”
Amy Floyd, Nutrition Counseling Client
“Thanks Andrea for an amazing presentation, I have heard all positive remarks from attendees and the evaluations show the same sentiment. It is really gratifying when a speaker does their “homework” and weaves in our profession’s day to day challenges within their content, you did an awesome job of this! You truly took the “die” out of Dietician! Your information on healthy eating and simplifying how we can work towards this as we are all so busy really hit the mark. Andrea connects very well with her audience; she is energetic, funny, and very approachable.”
Carole Ann LaGrange, Transfusion Medicine Safety Officer

I am a family physician who sees patients with a myriad of eating concerns – from wanting to know how to plan healthy meals for active families, to weight loss, to eating disorders, and so on. I cannot recommend the Health Stand team highly enough. I have worked with (and been to!) other Dieticians in the past and too often find that they just ask for food logs and make suggestions that are easily obtained online or in books. The Dieticians at Health Stand offer much more than just telling clients what they “should be eating.” In contrast, the team really does more of a counselling practice, and they work hard to help their clients learn more about why their eating habits may be off track and not optimal for them, as well as helping people to effect change at a deep level that, most importantly, is sustainable for lifetime health.”
Dr. Deb Putnam, Family Physician

“I am a busy mom, with kids in high level sports, working full-time downtown, and running our home acreage outside the City. I now have the knowledge and tools I need to plan for and manage the chaos of meal planning.”
Gillian Gray, Pursuit of Healthiness Online Course Participant
“As a construction company, we select speakers who can relate to our industry and its employees. Andrea’s message was delivered with humor and empathy. She makes people feel as though they can make changes without leaving behind every favorite food. Andrea focused her presentation on healthy eating as a way to keep energy high throughout the day. This message and the way it was delivered resonated with our predominantly male, blue collar culture. I would highly recommend Andrea as a speaker for groups such as ours. She will get your message across without alienating anyone in your audience – which is a huge hurdle when trying to introduce a wellness program in the workplace!”
Stephanie Wood, HR and Safety Manager

Fisher Construction Group, Burlington, WA

I found my Dietitian warm, funny, and skilled at teaching nutrition concepts without the overwhelm. The general approach of each session was to mix science with emotion, which was exceedingly effective in helping me shift my perspective on food from one of anxiety to one of joy and curiosity.”
Erin Kronstedt, Nutrition Counseling Client
“Excellent presentation! What a refreshing change to have a speaker inspire rather than “lecture” about nutrition. Your captivating stories, tips and overall approach to healthy eating uplifts and puts people at ease. It was great to hear we don’t need to strive to be perfect eaters, and that small changes really can make a difference in how we feel and in our health. Thanks to Andrea, we have solutions to our everyday nutrition challenges that can actually work in real life!”
Tina Tamagi, Human Resources

ARC Resources Ltd.

“Had I not joined this course I would have struggled with no focus, low energy, and mindless eating. Excellent teaching and motivation. This is not just a course, it is a nutrition club with mentorship, support, and connections with other people with similar situations.”
