Endometriosis and Fatigue

Ok, we have already learned so far that endometriosis is a whole-body condition that affects more than just the reproductive system. And one of the most debilitating and misunderstood effects of endometriosis is fatigue.

It's not just "being tired." It's a deep, relentless exhaustion that doesn't improve with rest and can make even the simplest tasks feel overwhelming.

This level of fatigue can disrupt daily life, interfere with work, relationships, and self-care, and lead to a frustrating cycle of pushing through exhaustion, only to crash even harder. For many, it's just as life-altering as the pain.

But here's the truth: you don't have to accept fatigue as your reality (like many other endo symptoms). You can rebuild resilience and reclaim your strength by understanding what causes it and taking strategic steps—through intentional movement, nervous system regulation, and energy optimization.

But let's answer first question: Why Does Endometriosis Cause Fatigue?

Fatigue in endometriosis isn't just about getting less sleep. It's a direct result of biological dysfunction happening at multiple levels. The body is working overtime to deal with inflammation, immune dysfunction, hormone imbalances, and nervous system dysregulation, all of which deplete energy at a cellular level.

1. Chronic Inflammation and Immune System Overload

Endometriosis is an inflammatory disease, and this chronic inflammation hijacks energy production.

- The immune system is constantly activated, releasing pro-inflammatory cytokines that make the body feel like it's fighting an infection 24/7.

- Inflammation damages mitochondria, the energy powerhouses of cells, making it harder for the body to generate energy efficiently.

- This inflammatory response also contributes to muscle pain, brain fog, and mood disorders, making fatigue feel even heavier.

2. Nervous System Dysfunction and Energy Drain

Endometriosis can cause dysregulation of the autonomic nervous system (ANS), meaning the body struggles to balance functions like heart rate, digestion, and energy regulation.

- Many with endometriosis experience dysautonomia, which can cause lightheadedness, blood pressure fluctuations, poor circulation, and extreme fatigue.

- The nervous system gets stuck in a stress response (fight or flight mode), preventing proper recovery and draining energy reserves.

- HRV (Heart Rate Variability) research shows that people with endometriosis have lower stress resilience, making fatigue harder to recover from.

3. Hormonal Imbalances That Worsen Fatigue

Hormonal fluctuations in endometriosis can contribute to low energy levels and difficulty recovering from exertion.

- Estrogen dominance and progesterone resistance affect how the body regulates sleep, stress, and metabolism.

- Cortisol dysregulation (caused by chronic stress) leads to poor blood sugar stability and worsening crashes in energy levels.

- Low testosterone in people with endometriosis has been linked to decreased muscle strength, endurance, and fatigue.

4. Mitochondrial Dysfunction and Energy Breakdown

Mitochondria are responsible for creating ATP, the body's primary energy source. Inflammation and oxidative stress in endometriosis damage these mitochondria, leading to reduced energy output.

- This means even basic activities feel exhausting.

- Nutrient deficiencies (such as low iron, B vitamins, and CoQ10) can further impair mitochondrial function, making it difficult for cells to generate energy effectively.

5. Sleep Disruptions That Prevent Recovery

Pain, inflammation, hormone fluctuations, and stress all contribute to poor sleep quality, making it even harder to restore energy.

- Studies show that people with endometriosis are more likely to have insomnia, restless sleep, and wake up feeling unrefreshed.

- Pain disrupts deep sleep cycles, preventing the body from getting true restorative rest.

- Poor sleep leads to higher inflammation and lower mitochondrial function, creating a vicious cycle of fatigue and burnout.

We can deal with fatigue in different ways. Many people with endometriosis are told to "take it easy" or avoid physical exertion. While rest is essential, prolonged inactivity can actually worsen fatigue. The body adapts to what it does most—so the less you move, the more difficult it becomes to move at all.

Intentional movement is different from just exercising. It's about training in a way that builds resilience, improves energy efficiency, and strengthens the body without triggering exhaustion.

At EndoFit, I focus on three key areas that can transform the way you manage endometriosis-related fatigue:

1. Strength Training

Strength training isn't just about building muscle—it's about improving mitochondrial function, reducing inflammation, and regulating hormones.

Lifting weights can improve endurance and reduce overall fatigue.

Progressive resistance training enhances blood flow and oxygenation, helping fight brain fog and sluggishness. Personalized programs can help you rebuild energy without overloading your system.

2. Cardiovascular Conditioning

Cardio isn't about exhausting yourself but improving oxygen efficiency and nervous system balance.

Interval training helps increase stamina without excessive stress. Functional conditioning improves endurance for daily activities. And my goal is to integrate cardio intelligently so you build energy, not burn it out.

3. Nervous System Resilience Through Movement

Since endometriosis places constant stress on the nervous system, movement should also train the body to recover and manage stress more effectively.

Breathwork during exercise regulates heart rate and energy balance.

EndoFit's programs focus on balancing movement with nervous system recovery so you feel more energized and in control.

By incorporating these three key elements, we help you transform fatigue into strength, allowing you to train smarter, not harder.

Additional Strategies to Boost Energy & Recovery

1. Prioritize High-Quality Sleep

Since endometriosis can cause disrupted sleep cycles, creating an environment that promotes deep, restorative rest is essential.

1. Maintain a consistent bedtime to support circadian rhythm.

2. Reduce blue light exposure at night to improve melatonin production.

3. Create a cool, dark, and quiet sleep space to minimize disturbances.

2. Breathwork to Regulate Energy & Stress

Breathwork can lower inflammation, balance stress hormones, and improve endurance.

1. Coherence breathing (slow, rhythmic breathing) can improve energy stability (I love to count seconds, and inhaling 8s and exhaling 8s works very well with me).

2. Box breathing (inhale 5s, hold 5s, exhale 5s, hold 5s) is great for nervous system regulation.

3. Physiologic sighing (two short inhales, one long exhale) can rapidly reset stress levels.

3. Meditation for Nervous System Balance

Meditation isn't just for relaxation—it actively reduces nervous system hyperactivity and helps regulate the body's energy production.

As mentioned in the article "Small Habits, Big Impact," I suggest that you download the application WakingUp (not sponsored, by the way.:)). It is an excellent tool for meditation with topics and extra learning segments. Another great and cheap start is Yoga Nidra.

Give it a go on a days that you feel extra tired :)

Endometriosis-related fatigue is complex, but it is not impossible to improve. Moving with intention, prioritizing recovery, and supporting the body at a cellular level makes it possible to break free from the cycle of exhaustion.

It takes time, patience, and the right approach, but every small step adds up. The goal isn't just to have more energy—it's to build a body that can sustain that energy long-term.
