Why Am I Always So Tired? 5 Hidden Causes of Low Energy in Women 35+

Low Energy in Women Is Often Misunderstood and no, It's Not “Just about Aging”

“I used to think constant fatigue was just part of life as I got older. Turns out, my body was trying to tell me something.” -- Nelea Lane

If you're experiencing low energy, especially as a woman over 35, it’s easy to assume you’re just doing too much or not sleeping enough.

That’s where I was too. What I didn’t realize at first was that my energy followed patterns. Certain times of day felt harder. Stress showed up in my body before it showed up in my schedule.

For many women, low energy isn’t random. It’s often connected to deeper imbalances, from hormone shifts to gut health disruptions, nutrient gaps, or emotional burnout.

You deserve to understand what your body may be responding to and take a clear next step without guessing.

5 Hidden Causes of Low Energy in Women 35+

1. Hormone Imbalances (Including Perimenopause + Post-Hysterectomy)

Hormones naturally fluctuate as we get older — but things like estrogen dips, thyroid changes, and post-hysterectomy shifts can leave your energy levels in a constant state of flux. If you’ve been noticing brain fog, energy crashes, or mood dips alongside your cycle (or even without one), hormones may be part of the story.

"I felt like I was dragging myself through the day. Turns out? It wasn’t burnout. It was my hormones." -- Nelea Lane

What surprised me most was how easy it was to mistake this for stress or motivation, when it was really a capacity issue.

2. Nutrient Deficiencies (Even if You Eat Pretty Well)

This was one of those areas where “eating well” didn’t tell the whole story, especially when stress and digestion were part of the picture.

For women especially, low iron, magnesium, B12, and vitamin D are common culprits in fatigue. Stress and poor gut absorption can make it harder to absorb nutrients even when you’re eating healthy. A quick blood panel and the right support can make a huge difference.

3. Gut Health Issues

Your gut does more than digest food. It also impacts your mood, motivation, and mental clarity. If your gut-brain axis is out of balance, your energy can take a major hit. Think: afternoon crashes, poor sleep, low serotonin, and inflammation. This gut–brain connection is one of the most overlooked pieces of energy. It’s also where many women first start noticing patterns.

For many women, this is where things finally start to connect, not because the gut is the problem, but because it reflects what the body has been managing for a while.

If this is landing with you…

Many women get to this point and realize something important. Low energy isn’t random. It’s a pattern.

And when patterns show up, the next step usually isn’t more tips. It’s learning how to understand what your body has been signaling — without pressure or overwhelm.

This is usually where women choose to go next:

4. Chronic Stress and Nervous System Overload

We’ve normalized “always being on.” But your nervous system was never designed to live in constant go-go-go mode. Over time, this can disrupt your cortisol rhythm and leave you feeling flatlined. Stress management isn’t fluffy — it’s essential.

5. Lack of Restorative Sleep

You might be sleeping… but are you actually resting? Hormones, stress, and screen time all play a role in how well your body repairs overnight. If you wake up tired no matter what, it’s time to look deeper at sleep quality, not just quantity.
