The Role of Nutrition for Amenorrhea and Fertility


Women running on a wide pathAre you a female athlete with no period?

Have you been told that it is normal to not have your period while training?

Ready to have a baby but your period is still missing and you don’t understand why?

You may be loving aspects of not having your cycle because it means no cramps and less mess. Please hold off on those party balloons, as not having your cycle has some serious health repercussions, one important one being fertility.


What is amenorrhea?


The lack of period is known as amenorrhea and may likely be hypothalamic amenorrhea (HA) but very few women get a HA diagnosis. Amenorrhea refers simply to a missing period and there can be many causes of this including PCOS (polycystic ovary syndrome) and endometriosis.

HA is when the hypothalamus is involved, and signalling gets messed up due to hormone imbalances and chemical mess-ups. I have spoken to multiple different clients, colleagues and friends who have experienced HA at some point in their life. The cause of it may be a combination of undereating, energy imbalance, over exercising, stress and genetics. The exact combination and degree of cause will look different for anyone who experiences HA.

Let’s take a quick jump over to athletes…


Causes of amenorrhea in athletes


Athletes experiencing a lack of period is not normal (unfortunately I have heard too many athletes say their physician told them this is normal)!

The combination of training and low energy availability can lead to a loss of menstrual cycle which is brushed off as a normal part of being an athlete all too often.

Low energy availability does not mean you are underweight or have an eating disorder. It means that you do not have the energy coming in that sustains your menstrual cycle on top of your high volume of training.

Many health professionals often miss this concern since you may be a healthy body weight (according to the BMI categories) and are very active (what we see as a ‘healthy’ lifestyle) yet your cycle has disappeared. When you lose your menstrual cycle this is a clear sign that something is off with your health.


The challenges of not having a period


Your menstrual cycle is a vital sign, it tells us more about what is going on with your body than just your reproductive function. Putting fertility aside for one second (as this is definitely one of the negative health effects of no period), the absence of a period means estrogen, progesterone and testosterone levels drop. This will affect athletic performance.

The other short-term effects include thinning or loss of hair, brittle nails, low libido and skin problems. Long term, it leads to weak and brittle bones, cardiac disease, increased risk of early dementia and earlier cognitive (estrogen is highly protective of brain cells).

Before you panic, regaining of your cycle can reverse negative changes or prevent further damage.

Your menstrual cycle is a vital sign of health!


What should I do if I have missing menstrual cycles?


Regaining your period is very possible but it will take some work and commitment. With every individual having a different combination of factors at varying degrees to why they lost their period, the treatment to regaining of your period will all look slightly different.

For some, the addition of a few more snacks for a few months is the key, others, it means slowing exercise down for a bit and keeping intake the same; but for some, it takes a bit more tinkering with the factors before a result is seen.

Nicola Rinaldi, PhD and author of “No Period, Now What?” states that a full recovery plan will include eating more for a while, cutting out high-intensity exercise, working on negative thoughts and mental health and allowing the body time to re-equilibrate. This will not happen over night. Support is also critical!

Getting support from loved ones, teammates and coaches is greatly important, but you may also need support from a health care team that can include a Registered Dietitian, Therapist and Doctor.

In a survey done by the writers of No Period, Now What, out of over 300 women, 53% were able to regain their natural cycles back, 90% were able to do this within 1 year of starting a recovery plan. 

I want to leave you with feelings of hope. Your period is a sign of health, no matter what anyone tells you. Even with a loss of period from amenorrhea, recovery is possible!


Nutrition for amenorrhea: where to start


Here are 3 important tips for you to keep in mind if you have lost your menstrual cycle when it comes to your eating and activity patterns:

Women running on a wide path

  1. Start slow. Whether you have been struggling with restricting or too much exercise or simply just not enough calories, it can be a difficult transition to increasing intake. Emotions like guilt, shame and frustration can quickly slip in. Start yourself with small increases and gradually build up. This can be adding in an afternoon snack or including grains with every meal.
  2. Progress not perfection! Recovery from HA is not going to happen overnight. Be kind to yourself in the process. I wish I could offer you a solution that was easy, but with diet culture and the never-ending messages we hear and see, it is difficult to now go against all those messages and increase intake and/or reduce exercise. Focus on the progress, not the so-called mistakes.
  3. Stop ‘healthifing’ every recipe. Generally, when a recipe is made to be ‘healthier’ it does not mean it is actually healthier for everyone. Often calories and fat are reduced in these recipes. When it comes to recovery, increasing energy intake is the focus so use the full fat yogurt, butter and cheese. Enjoy what you are eating and eat until you are satisfied.

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

Event Planner for Laboratory Diagnostic Imaging Annual Event

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

“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.”
