You’re doing everything right, so why do you feel so wrong?
You’re getting to bed on time. You’ve cut back on caffeine. You even downloaded a meditation app (although it now just makes you feel guilty when you ignore it).
Still, every morning you wake up feeling like you haven’t slept. You drag yourself through the day, powering through work, family life, and endless to-dos. But by evening, you’re too drained to do anything for yourself.
If this sounds familiar, you’re not alone. At The Dr Jenni Clinic, we see women every day, smart, capable, high-achieving women, who feel utterly worn out and they don’t know why.
So, let’s talk about fatigue, real, persistent fatigue. Not the kind that goes away with a good night’s sleep or a weekend off. The kind that makes you feel like you’re running on empty no matter what you do.
Fatigue Is a Symptom, not a Personality Flaw
The first thing we want to say is this: tiredness is not a moral failing. It’s not because you’re not trying hard enough or doing something wrong. Fatigue is a signal from your body and it’s worth listening to.
When you come to The Dr Jenni Clinic with fatigue as your main concern, we don’t just run a routine blood test and tell you to “get more rest.” We take it seriously because fatigue can be a sign of several different, and often overlapping, issues.
Five Common (and Overlooked) Causes of Persistent Fatigue
Let’s break down some of the most common reasons we see women feeling this way:
- Thyroid Dysfunction
Your thyroid is a small gland with a big job. It controls your metabolism, energy, and mood.
Even slight underactivity (hypothyroidism) can leave you feeling sluggish, cold, forgetful, and emotionally flat. We often see patients whose thyroid function is technically within range but far from optimal.
- Iron Deficiency
You don’t have to be anaemic to be affected by low iron. Many women in their 30s to 50s, especially those with heavy periods, have low ferritin levels (your iron stores).
Low iron can cause fatigue, hair thinning, brain fog, and shortness of breath. It’s one of the most fixable causes of exhaustion but easily missed.
- Post-Viral Fatigue or Low-Grade Inflammation
We’re seeing more patients who have never quite bounced back after COVID or another virus.
They’re not acutely ill, but never fully well. Their energy crashes in the afternoon. They feel “wired but tired.” This is often a sign of lingering inflammation or oxygen deficiency at the cellular level.
- Burnout
Chronic stress depletes your body. When cortisol (your main stress hormone) is out of balance, it can disrupt your sleep, mood, immunity, and energy production.
Many women power through for months or years before their body hits the brakes.
- Hormonal Imbalance (Including Perimenopause)
Even before your periods stop, hormonal changes can sap your energy. Fluctuations in oestrogen, progesterone, and even testosterone can leave you feeling exhausted, foggy, and emotionally flat. We don’t blame your hormones for everything, but we never ignore them.
Enter: Hyperbaric Oxygen Therapy (HBOT) A Game-Changer for Fatigue
If you’re dealing with chronic fatigue, burnout, long COVID symptoms, or just feel like your brain and body are stuck in first gear, HBOT could be a powerful part of your recovery plan.
Hyperbaric Oxygen Therapy involves breathing 100% oxygen in a pressurised chamber. It’s not new, it’s medically recognised and used worldwide for healing and recovery. More recently, it’s being used to support energy, clarity, and resilience in people who are simply running on empty.
At The Dr Jenni Clinic, our on-site HBOT chamber is part of a holistic medical approach. We use it to help:
- Boost oxygen delivery to tired tissues
- Reduce inflammation
- Support cellular healing and brain clarity
- Accelerate recovery from burnout or post-viral fatigue
- Complement hormonal or nutritional treatments
Many patients describe feeling lighter, calmer, and more energised after just a few sessions.
It’s safe, non-invasive, and tailored to your needs. Best of all, it gives you an hour of protected, uninterrupted time to rest and reset.
“But My Bloods Were Normal…”
This is something we hear every week: “My GP said everything is fine but I don’t feel fine.”
Here’s the truth: most standard tests look for disease, not dysfunction. At The Dr Jenni Clinic, we look at what’s optimal, not just what’s “in range.”
We combine blood testing, hormone insight, nutritional analysis, and sometimes cutting-edge therapies like HBOT to help you feel like yourself again.
Feeling Better Isn’t a Luxury, It’s Your Baseline
You weren’t meant to feel this exhausted. You weren’t meant to live on autopilot, and you certainly weren’t meant to accept tiredness as your new normal. We believe fatigue is a fixable symptom with the right support.
Whether you need hormonal balance, iron restoration, thyroid support, or time in the HBOT chamber, we’re here to help you get there.
