Is It PCOS or Are You Not Eating Enough? Understanding the Link Between Irregular Periods and Nutrition
Losing your period or having irregular bleeds can be a source of stress and confusion. Many women experiencing these symptoms often jump to the conclusion that they may have Polycystic Ovary Syndrome (PCOS), but the reality is that the root cause could be something else entirely, like under-eating.
While PCOS is a common hormonal disorder, some women may actually be suffering from Hypothalamic Amenorrhea (HA), a condition where the brain stops sending signals to the ovaries to ovulate, often due to insufficient nutrition. So, how can you tell the difference? Let’s explore this in more detail.
The Role of Nutrition in Ovulation
As you’ve probably heard me say, the menstrual cycle doesn’t start in the ovaries—it starts in the brain, specifically in a part called the hypothalamus. The hypothalamus communicates with the pituitary gland, which then sends signals to the ovaries to stimulate ovulation.
For this system to work properly, your body needs to feel that it’s in a safe and healthy environment. Part of this "safety" is determined by your nutritional status—specifically, whether you’re consuming enough macronutrients like carbohydrates, proteins, and fats.
Ovulation is an energy-intensive process. In fact, it takes approximately 50,000 calories to grow a baby during pregnancy. So, when your body senses that you aren’t eating enough or lack sufficient stored energy, it thinks it's doing you a favor by stopping ovulation altogether. This is how Hypothalamic Amenorrhea (HA) happens. Your body halts ovulation to conserve energy, preventing a potential pregnancy in an environment where it doesn't seem like there's enough food to sustain it.
But How Do You Know If It’s PCOS or Hypothalamic Amenorrhea (HA)?
Many of the symptoms of PCOS and Hypothalamic Amenorrhea overlap, especially when it comes to irregular or missed periods. This can make it hard to figure out what’s really going on with your body. However, there are key differences between the two conditions:
1. Nutritional History
- PCOS: Women with PCOS typically don’t have a history of under-eating or restrictive dieting. In fact, PCOS is often linked to insulin resistance, which can result in weight gain, particularly around the abdomen.
- Hypothalamic Amenorrhea (HA): If you’ve been cutting calories, avoiding carbohydrates, or over-exercising, your body might not be getting enough fuel to support ovulation. HA is commonly seen in women who have been dieting, have low body fat, or engage in intense physical activity.
2. Hormonal Levels
- PCOS: Blood tests often reveal elevated levels of androgens (male hormones like testosterone), along with higher levels of LH (luteinizing hormone) relative to FSH (follicle-stimulating hormone). Insulin levels may also be high, contributing to insulin resistance.
- HA: In contrast, women with HA often have low levels of FSH and LH because the brain isn’t sending proper signals to the ovaries. Androgen levels are usually normal or low, and insulin resistance is not typically an issue.
3. Physical Symptoms
- PCOS: Excess facial or body hair (hirsutism), acne, and weight gain are common signs of PCOS due to elevated androgen levels. Ultrasounds may show cysts on the ovaries, though this isn’t a definitive marker.
- HA: Women with HA are more likely to experience symptoms related to nutrient deficiency, such as hair thinning, brittle nails, feeling cold all the time, or low energy. There are typically no signs of high androgens or ovarian cysts.
4. Exercise and Stress
- PCOS: While exercise can help manage PCOS, excessive exercise isn’t typically a trigger for the condition. PCOS is more strongly linked to metabolic issues than lifestyle factors like stress or exercise.
- HA: Over-exercising or intense cardio, especially without adequate caloric intake, can trigger HA. Stress also plays a big role, as high levels of cortisol can further disrupt the hypothalamic signals that regulate ovulation.
Addressing the Root Cause: PCOS vs. Under-Eating
Regardless of whether you suspect PCOS or under-eating is causing your irregular periods, it’s crucial to focus on nourishing your body and supporting hormonal balance. Here’s what you can do depending on the root cause:
If You Suspect PCOS:
- Find the Root Cause of Your PCOS: PCOS can manifest in different forms, and the way to manage it will depend on the specific type. For example, it may be related to adrenal stress, blood sugar imbalances, or inflammation. To get started, it’s essential to explore which form of PCOS you may be dealing with and the root cause so you can follow the correct approach to support your body.
If You Suspect Hypothalamic Amenorrhea (HA):
- Increase Caloric Intake and Variety: Ensure that you are eating enough calories to fuel your body and include all three macronutrients—carbohydrates, proteins, and fats. Skipping out on any of these can signal to your body that it doesn’t have enough energy to support ovulation.
- Include More Carbohydrates: Low-carb or restrictive diets are common triggers of HA, so adding healthy carbohydrates like whole grains, fruits, and starchy vegetables is essential. Your body needs this fuel to support the reproductive system.
- Don’t forget about protein—adequate amounts of lean meats, fish, eggs, and plant-based proteins are crucial for hormone production and overall health.
- Reduce Excessive Exercise: If you’ve been over-exercising, now is the time to focus on more restorative forms of movement. Gentle activities like walking, yoga, or pilates can help reduce stress on your body while still keeping you active.
- Rest and Recover: Adequate sleep and rest are vital to restoring your hormonal health. Make sure you’re giving your body the time it needs to recover and reset.
Final Thoughts: Take Care of Your Body, and It Will Take Care of You
It’s easy to jump to conclusions when faced with irregular periods or a loss of ovulation, but not all menstrual issues point to PCOS. Hypothalamic Amenorrhea (HA) is a common but often overlooked condition that can be reversed by nourishing your body with enough food, reducing stress, and giving your body the rest it needs.
If you’re unsure about what’s causing your symptoms, take a step back and assess your lifestyle, nutrition, and stress levels. Once you understand your body’s needs, you can make adjustments to support your hormonal health and get your cycle back on track.
