Fatigue Doctor in Dallas
Always Tired? Let’s Find Out Why.
In-depth testing for the iron, thyroid, hormone, blood sugar and sleep problems behind ongoing fatigue, from our functional medicine team in East Dallas.
Why Am I Always Tired?
Ongoing fatigue usually has a cause that can be found. The most common ones are low iron or anemia, low vitamin B12 or vitamin D, thyroid problems, blood sugar and insulin problems, low testosterone or menopause, poor sleep or sleep apnea, stress, depression, medication side effects and the lingering effects of an infection. Many people have more than one.
At Regen Wellness in Dallas, a licensed provider takes a full history and runs in-depth labs to find what's draining your energy, then builds a plan around what we find. If your fatigue points to a condition that needs a specialist, we'll tell you.
Common Causes of Fatigue We Test For
A standard checkup often checks only a few of these. We look at the whole picture, because fatigue rarely has a single cause.
Iron, B12 & Vitamin D
Low iron stores (ferritin) can cause fatigue before you're anemic. Low B12 and vitamin D are common and easy to miss.
Thyroid
An underactive thyroid slows everything down. We check a full thyroid panel, including antibodies for Hashimoto's.
Thyroid & Hashimoto's →Blood Sugar & Insulin
Energy crashes after meals, cravings and weight gain around the middle can point to insulin resistance.
Weight gain & metabolism →Hormones
Low testosterone in men, and perimenopause and menopause in women, are common and treatable causes of low energy.
Hormone therapy →Sleep
Snoring, waking unrefreshed or morning headaches can mean sleep apnea, which needs a sleep study. We'll refer you if it's likely.
Gut, Inflammation & Exposures
Gut problems, autoimmune conditions, mold exposure and past infections can all leave people drained.

Fatigue Lab Testing: Standard Checkup vs. Our Panel
Many patients come in after being told their labs were normal. Often only a few markers were checked. Here's what we typically add.
| Area | Often in a standard checkup | What we typically add |
|---|---|---|
| Iron | Hemoglobin (complete blood count) | Ferritin, iron and iron saturation, to catch low stores before anemia |
| Thyroid | TSH only | Free T4, free T3 and thyroid antibodies |
| Nutrients | Sometimes none | Vitamin B12, folate, vitamin D and magnesium |
| Blood sugar | Fasting glucose | Hemoglobin A1c and fasting insulin |
| Hormones | Usually none | Testosterone, estradiol, progesterone and others based on your age and symptoms, plus morning cortisol when stress hormones are a question |
| Inflammation | Usually none | hs-CRP, and other markers if your history points to autoimmune or mold-related illness |
Your provider chooses tests based on your symptoms and history, so not everyone needs every test. Some can be billed to insurance. See lab testing.
What About Adrenal Fatigue?
"Adrenal fatigue" is a popular term for the worn-out feeling that comes with long-term stress. It isn't a recognized medical diagnosis. The Endocrine Society and other medical groups have found no evidence that the adrenal glands "burn out" from stress.
Your exhaustion is still real, and stress does affect your body. So instead of labeling it adrenal fatigue, we test what can be measured:
- Cortisol, using properly timed tests, to look for real adrenal problems such as adrenal insufficiency, which is rare but serious.
- The common causes above, such as iron, thyroid, blood sugar and hormone problems, which are often what's behind the symptoms.
- Sleep, stress and recovery, because they affect energy as much as any lab result.
Signs That Need Prompt Care
See a doctor soon if fatigue comes with unexplained weight loss, fever or night sweats, shortness of breath or chest pain, fainting, blood in your stool, or a new lump.
If you're feeling hopeless or having thoughts of harming yourself, call or text 988 to reach the Suicide & Crisis Lifeline, or call 911.
How We Evaluate and Treat Fatigue

Tell us how long you've been tired, what makes it better or worse, and what you've already tried.
Provider visit
A licensed provider reviews your history, sleep, stress, diet, medications and past test results, and orders the labs that fit.
Lab review and plan
We walk you through your results in plain language. Your plan treats what we find, such as replacing low iron or B12, treating thyroid or hormone problems, or improving blood sugar, along with sleep, nutrition and activity changes. When you need a supplement, your provider will recommend a specific one, and you can find the practitioner-grade vitamins and minerals we use in the vitamins A to zinc collection at Regen Wellness Vitamins, our supplement store in the same suite.
Support while you recover
Some patients add IV therapy, such as vitamin and NAD+ infusions, while the underlying cause is being addressed. These are optional add-ons, not a replacement for finding the cause.
Follow-up
We recheck labs and how you feel, and adjust the plan. Many follow-ups can be done by telehealth.
Chronic Fatigue Syndrome (ME/CFS) and Long COVID
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a serious, long-term illness. Its hallmark is a crash after physical or mental effort that can last days, known as post-exertional malaise. Long COVID can cause a similar pattern.
There's no cure for ME/CFS, and pushing through exercise can make it worse. If your symptoms fit this pattern, we'll check for other treatable causes, help you manage your energy, support sleep and other symptoms, and refer you to specialists when that's the right step.

What kind of doctor should I see for fatigue?
Start with your primary care doctor or a functional medicine provider who will take a full history and run thorough labs. Depending on what's found, you may also need an endocrinologist, sleep specialist or another specialist.
What blood tests should I ask for if I'm always tired?
A complete blood count, ferritin, a full thyroid panel, vitamin B12, vitamin D, A1c, a metabolic panel and, depending on your age and symptoms, sex hormones. Your provider may add others based on your history.
Why am I tired even after a full night's sleep?
Unrefreshing sleep can come from sleep apnea, low iron, thyroid problems, hormone changes, depression, alcohol or some medications. Snoring, gasping at night or morning headaches are reasons to ask about a sleep study.
Is adrenal fatigue real?
The symptoms are real, but "adrenal fatigue" isn't a recognized diagnosis, and there's no evidence that stress wears out the adrenal glands. We test cortisol properly and look for the causes that usually explain those symptoms.
Can IV therapy help with fatigue?
IV therapy corrects a deficiency only if you have one, and it doesn't fix the underlying cause. Some patients find vitamin or NAD+ infusions helpful as support while that cause is treated. We'll tell you whether it makes sense for you.
How long until I have more energy?
It depends on the cause. Some people feel better within weeks of correcting low iron, B12 or thyroid levels. Others, especially with several causes or long-term illness, improve more gradually over months.
