Welcome to The Veterans Disability Nexus, where we provide unique insights and expertise on medical evidence related to VA-rated disabilities. Leah Bucholz, a US Army Veteran, Physician Assistant, & former Compensation & Pension Examiner shares her knowledge related to Independent Medical Opinions often referred to as “Nexus Letters” in support of your pursuit of VA Disability every Tuesday & Wednesday at 7AM Central.

Hey, guys. It's Leah B from Prestige Veteran Medical Consulting. So today, I wanna talk about being tired. Right? So you're not just tired.
leah B:You're you're exhausted. You wake up tired. You crash midday. Your body feels heavy. Your brain feels slow.
leah B:Maybe your labs are normal. Maybe your thyroid is normal. Maybe your doctor says everything looks fine, but you don't feel fine. Today, we're talking about chronic fatigue, what it actually means medically, why it's so complex, and why so many veterans struggle with it. This again, this is always my I gotta throw out my, disclaimers.
leah B:So this is educational only, not medical advice. I am a, you know, physician assistant, former CMP examiner, army veteran, but this is just in generalities we're gonna talk today, guys. Okay? So let's break it down. Fatigue is a symptom.
leah B:It is not a diagnosis. Now chronic fatigue syndrome is a diagnosis, but that's a that's another we're not talking about that. We're just talking about fatigue. Fatigue is one of the most common complaints in medicine, but it's not just a single condition. It can reflect things like sleep disruption, hormonal imbalance, chronic inflammation, autonomic dysregulation, depression, chronic pain, medication side effects, deconditioning, stress physiology.
leah B:That's why it's often, very difficult to pinpoint. It can be a mixture of a lot of those things. So you can have sleep fragmentation. We've talked about that a lot, especially in PTSD and depression. Even if you don't realize it, you can get seven to eight hours of sleep and still wake up exhausted.
leah B:Why? Because restorative sleep depends on deep sleep cycles. So REM cycles are important, stable breathing, low sympathetic activation. If sleep is fragmented by things like hypervigilance that people can experience with PTSD, nightmares, pain, subclinical breathing disturbances, stress hormones. You don't get restorative recovery.
leah B:Alright? Over time, that can lead to things like cognitive slowing, irritability, poor exercise tolerance, increased inflammation. Sleep quality matters more than sleep quantity for real. So, again, you can sleep eight or ten hours. And if you're not getting into that deep sleep because you keep having disruptions, that's just not super helpful.
leah B:So autonomic dysregulation. The autonomic nervous system regulates energy, distribution. If it's stuck in sympathetic overdrive, right, you're always in this threat response. You're always in this fight or flight. Rest and digest processes can suffer.
leah B:Heart rate variability drops. Recovery slows. You may feel wired but tired, or you can crash unpredictably. This is common in chronic stress states and PTSD physiology. So inflammation and immune activation.
leah B:Low grade inflammation can produce things like fatigue, brain fog, muscle aches, reduced endurance, even if inflammatory labs are technically within range. Chronic immune activation is energy expensive. Your body diverts resources towards immune signaling that can feel like exhaustion. Chronic pain drains energy. So pain consumes metabolic and neurologic resources.
leah B:Persistent pain activates stress pathways. It can disrupt sleep, and it can increase muscle tension, alter hormonal regulation. Chronic pain and fatigue frequently coexist, and that's not a coincidence. It's it's just physiology. So medication side effects are also important things to think about.
leah B:Some commonly prescribed medications may contribute to fatigue. Antidepressants can contribute to this. Certain ones. Right? Not all of them.
leah B:Antihypertensive medications. Certain pain medications can cause drowsiness. Sleep aids, of course. Not because they're inherently harmful, but because they alter neurologic signaling and energy regulation. So medication review is important in persistent for fatigue for, doctors to take a look at.
leah B:So hormones and metabolic health. Fatigue can also be influenced by things like your thyroid function, testosterone levels, that's a huge one, insulin resistance, cortisol rhythm, vitamin D. Right? If your vitamin D is low, that can cause a lot of depleted energy. But even when labs are technically normal, subtle dysregulation patterns may exist that don't cross a diagnostic threshold.
leah B:Again, physiology operates on a spectrum, not in, like, a binary way. So serious causes have to be ruled out. K? So persistent fatigue should be evaluated medically to rule out a variety of things depending on your circumstances, but things like anemia, thyroid problems, sleep apnea, huge one. K?
leah B:Huge. Especially in our veteran population. Cardiac conditions, autoimmune diseases, infections. So this again, this video is not gonna replace medical evaluation or advice. But once serious pathology is excluded, fatigue often reflects regulatory imbalance rather than structural failure.
leah B:So how does this relate to VA disability from a medical perspective? So from a VA disability standpoint, fatigue by itself is usually not rated in isolation. I mean, it can be rated as chronic fatigue syndrome, but, know, we've got some specific videos on that you should check out. So it's typically evaluated in the context of whatever the underlying condition is, such as sleep disorders, PTSD, chronic pain conditions, autoimmune disease. So if it's fatigue as a symptom, it's it's what is that condition that it's related to.
leah B:Gulf War related syndromes, endocrine disorders. What matters medically is is the fatigue chronic? Is there a diagnosable condition? Is there documented functional impairment? Is there a plausible physiologic mechanism?
leah B:Understanding the medical basis of fatigue helps clarify how it may be evaluated within the VA system. So for claim specific guidance strategy or appeal guidance, I always always say, you know, if you need help, go with a VA accredited representative like a VSO or claims agent or an attorney. The bigger picture here is that chronic fatigue is rarely one single issue. It's usually layered, by things like poor sleep, stress physiology, pain, inflammation, hormonal shifts, right, like low testosterone. A lot of these things are interconnected.
leah B:Deconditioning, when those stack together, energy can just collapse. So understanding that complexity removes the false idea that fatigue is just laziness or weakness. It can be physiologic. So I guess the takeaways here are, essentially, if you've been struggling with chronic fatigue, I hope, that this helped explain why it can be so multifactorial and difficult to untangle, that the body reflects both stress and history. This video, again, is for educational purposes only.
leah B:Please follow-up with your doctors if you're experiencing a lot of these symptoms so they can try to figure out what's going on with you. If you're experiencing persistent or worsening fatigue, follow-up with your primary care provider or a qualified medical professional for individualized evaluation and care. Every case is unique, and proper assessment is essential. If this was helpful, please like and subscribe. I regularly break down these VA related topics from a medical perspective, using evidence based research.
leah B:So I'll see you guys in the next video. Please drop some comments if y'all have any questions or feedback. Alright. See you later.
