Fatigue, Sleep & Low Energy Treatment in Denver, CO
Struggling to Sleep? Discover Targeted Mood & Rest Solutions
Constant fatigue and poor sleep usually have a findable cause — shifting hormones, an underactive thyroid, low iron or vitamin D levels, blood sugar swings, or disrupted sleep. At Cunningham Clinic in Denver's Cherry Creek neighborhood, nurse practitioner Kimberly Cunningham looks past quick fixes, tests for the real drivers of your low energy, and builds a conservative, individualized plan to help you feel genuinely rested and energized again.
Better sleep and steadier moods often go hand in hand, so Kimberly takes both seriously. She listens closely to how you're feeling—from restless nights to irritability, low motivation, or anxiety that can come with hormonal shifts—and connects the dots to what your labs reveal. With years of experience supporting women through perimenopause and menopause, she explains your options in plain terms and adjusts your plan as your body responds. The goal is simple: help you wake up clearer, feel more like yourself, and move through your days with steady energy and a brighter outlook.
Better Sleep and Mood Support in Denver, CO
Restless nights often trace back to something real—shifting hormones during perimenopause and menopause, ongoing stress, or other underlying causes that quietly disrupt your sleep. When rest suffers, so does the rest of your life, leaving you with low energy, unsteady moods, and an emotional balance that feels harder to hold onto each day.
Restful sleep starts here.
Why am I always tired?
Persistent tiredness is a symptom, not a diagnosis — and in most people it traces back to one or more identifiable, testable causes rather than simply being busy or getting older. The most common drivers are hormonal shifts, thyroid imbalance, nutrient deficiencies, blood-sugar and metabolic issues, and poor sleep quality.
The key is to test rather than guess. When we find and address the actual cause, energy and sleep usually improve in a way that caffeine and willpower never deliver on their own.

Signs your fatigue is worth evaluating
Everyone has tired days. It is worth a closer look when you notice patterns like these:
• Exhaustion that does not improve with rest
• Trouble falling asleep, staying asleep, or waking unrefreshed
• Afternoon energy crashes
• Relying on caffeine to get through the day
• Brain fog, poor focus, or low motivation
• Low libido or mood changes alongside the fatigue
• Unexplained weight changes
• Poor recovery from exercise
Steady moods, brighter days
Common root causes we look for
Because fatigue has many possible drivers, we evaluate the most common and treatable ones together rather than fixating on a single cause:
• Hormone shifts — perimenopause and menopause in women, low testosterone in men
• Thyroid imbalance (an underactive thyroid is a classic, treatable cause of fatigue)
• Nutrient deficiencies — low iron/ferritin, vitamin D, vitamin B12
• Blood-sugar and metabolic patterns that drive energy crashes
• Stress and cortisol rhythm, and how they affect your sleep and recovery
• Sleep quality and habits, including signs that point to a sleep disorder worth further evaluation
A quick note on terms: you may have read about “adrenal fatigue.” It is not a recognized medical diagnosis, but the real symptoms behind that search — exhaustion, poor sleep, and stress — are very real and very treatable once we identify what is actually going on.

How we treat low energy and poor sleep at Cunningham Clinic
We start with a thorough evaluation and targeted lab work, then treat the specific causes we find — using the least intervention necessary. Your plan may combine any of the following:
Comprehensive evaluation and lab testing
We review your symptoms, sleep, and history and order targeted labs — hormones, thyroid, iron, vitamin D, B12, and metabolic markers — so your plan is built on data, not guesswork.
Hormone optimization and Biote pellet therapy
When fatigue is driven by hormone shifts, restoring balance can transform energy and sleep. As a Biote Certified clinic, we offer bioidentical hormone options, including pellet therapy, for the right candidates.
Thyroid and nutrient support
If your thyroid is underactive or your iron, vitamin D, or B12 are low, correcting them is often the single biggest lever for getting your energy back.
Medical-grade supplements
We carry and recommend only vetted, professional lines — such as Thorne and Xymogen — chosen for clinical evidence and ingredient integrity, matched to what your labs and symptoms actually show.
Sleep and lifestyle plan
Practical, sustainable guidance on sleep timing, light, movement, nutrition, and stress — the foundations that make every other treatment work better.
Ongoing monitoring
We recheck labs and symptoms and fine-tune your plan so improvements in energy and sleep hold over time.

Frequently Asked Questions
Getting enough hours of sleep does not guarantee restorative sleep or rule out other causes. Hormone shifts, thyroid issues, low iron or vitamin D, blood-sugar swings, and poor sleep quality can all leave you tired despite time in bed — which is why testing matters.
We commonly check thyroid function, iron and ferritin, vitamin D, vitamin B12, blood sugar and metabolic markers, and relevant hormones such as testosterone, estrogen, and progesterone. We tailor the panel to your symptoms.
Yes. Perimenopause and menopause in women, low testosterone in men, and an underactive thyroid are all common, treatable hormonal causes of low energy and poor sleep.
Adrenal fatigue is not a recognized medical diagnosis, though the symptoms people use it to describe are real. We evaluate genuine, testable causes of fatigue and your cortisol rhythm rather than treating an unproven label.
Targeted, professional-grade supplements can help when your labs show a specific deficiency, such as low iron, vitamin D, or B12. They work best as part of a plan that addresses the underlying cause rather than as a blanket fix.
It depends on the cause. Correcting a nutrient deficiency or thyroid issue can help within weeks, while hormone optimization may take a bit longer. We monitor and adjust so improvements last. Results vary by individual.
