You're getting eight hours of sleep, you've cut back on the late-night snacks, and you're drinking plenty of water — yet you still feel like you're dragging through mud. It's a frustrating cycle that many people mistake for just "getting older" or working too hard. But if your exhaustion won't go away, it's often because your internal chemistry is out of sync.
At Alevizos Medical, John G. Alevizos, DO, understands that chronic fatigue isn’t a matter of willpower. Hormones are one possible piece of the puzzle, especially when fatigue appears with symptoms such as poor sleep, weight changes, low libido, mood changes, brain fog, or changes in strength.
Hormones act as the software for your body, telling your cells when to burn fuel and when to rest. If the software is glitchy, your energy production stalls. There are three main areas where we see these links most often.
Testosterone plays a role in muscle mass, red blood cell production, libido, and energy, especially in men with clinically low testosterone. In women, the relationship between testosterone levels, symptoms, and treatment is more complex, so Dr. Alevizos evaluates symptoms, health history, and lab results before recommending any treatment plan.
Low testosterone may contribute to changes in muscle mass, strength, stamina, libido, mood, and overall well-being, but symptoms alone don’t confirm a diagnosis. Lab testing and a full medical evaluation help determine whether hormones are part of the problem.
Similarly, a drop in estrogen and progesterone during menopause can disrupt GABA — a calming brain chemical — and melatonin. This damages your sleep architecture, which is the natural structure of your sleep cycles. The result is that you wake up feeling un-rested, no matter how long you were in bed.
Your thyroid is your body's thermostat. When thyroid hormone levels are low, your body may slow down, causing fatigue, weight gain, cold intolerance, dry skin, constipation, low mood, or brain fog.
On the other hand, if your energy crashes right after you eat, it's often a sign of insulin resistance.
Insulin resistance can also affect energy. When your body doesn’t respond well to insulin, blood sugar regulation becomes less efficient. That can leave some people feeling tired, foggy, hungry, or sluggish after meals.
Many patients come to us after being told their blood work is "normal," even though they're still struggling with debilitating fatigue. Lab results are important, but they don’t always tell the whole story on their own. Dr. Alevizos considers your symptoms, medical history, lifestyle, and hormone levels to understand how your body functions.
Dr. Alevizos also reviews lab results in the context of your symptoms and quality of life to see how your levels are actually affecting it. We don't just want your numbers to look good on a chart; we want you to feel like yourself again. By identifying these subtle gaps, we can create a plan that actually restores your vitality.
