Chronic Fatigue and Low Energy
Persistent fatigue is one of the most common—and often frustrating—symptoms people experience.
Many individuals are told their labs are “normal,” yet continue to feel:
- Constantly tired or drained
- Mentally foggy
- Unrefreshed after sleep
- Less resilient to stress or activity
Fatigue is not a diagnosis—it’s a signal. The key is understanding what’s driving it.
What Conventional Medicine Evaluates
A thorough medical evaluation is essential, as fatigue can be associated with a range of conditions.
Commonly evaluated causes include:
- Depression and anxiety
- Obstructive sleep apnea
- Hypothyroidism
- Iron deficiency anemia
- Type 2 diabetes
There are also important conditions that should not be missed, such as:
- Heart failure
- Chronic kidney disease
- Malignancy
In some cases, patients may meet criteria for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), particularly when fatigue is accompanied by post-exertional worsening of symptoms.
These evaluations are important—and often necessary as a first step.
When Everything Looks “Normal”—But You Still Feel Off
Many people do not fit neatly into a single diagnosis, yet continue to experience:
- Ongoing fatigue
- Brain fog
- Sleep disturbances
- Unexplained aches and pains
- Mood changes or low motivation
This is where a more comprehensive, systems-based approach becomes valuable.
A Functional Medicine Perspective
Rather than stopping at whether labs fall within a reference range, I look at why energy production may be impaired in the first place.
This includes evaluating:
- Metabolic health and insulin regulation
- Thyroid function beyond basic screening
- Nutrient status and absorption
- Chronic stress and nervous system load
- Sleep quality and circadian rhythm
- Inflammation and immune activity
- Environmental exposures and toxic burden
- Gut health and the microbiome
At a cellular level, many of these factors influence mitochondrial function—the process by which your body generates energy.
A More Individualized Approach
Fatigue is rarely caused by a single issue. More often, it reflects multiple subtle imbalances interacting over time.
A more personalized evaluation allows us to:
- Identify patterns that may be missed in standard testing
- Understand how different systems are interacting
- Develop a targeted, individualized plan
Is This the Right Fit?
This approach is often a good fit for individuals who:
- Continue to feel unwell despite “normal” labs
- Want a deeper understanding of their symptoms
- Are looking for a more comprehensive, root-cause approach
Next Step
If you’re experiencing ongoing fatigue and are interested in a more personalized evaluation, the next step is completing a pre-screening application.
I work with patients throughout Virginia and Florida via telehealth to better understand and address complex, ongoing health concerns like fatigue.
