Overview

Are you constantly tired—even after a full night's sleep? Do you feel like your energy is never quite where it should be? If you're living with persistent fatigue, it's not just in your head. Ongoing low energy can be a signal from your body that something deeper is going on.

Fatigue is one of the most common complaints people bring to doctors. And while it's often brushed off as "just stress" or "normal life," it's frequently tied to medical conditions that can and should be addressed.

Why do people experience persistent fatigue?

Your energy levels are influenced by everything from hormones and blood sugar to nutrient levels, sleep quality, and mental health. When even one part of that system is off, it can leave you feeling drained.

Thyroid disorders—particularly hypothyroidism—are a leading cause of low energy. If your thyroid is underactive, your body's metabolism slows down, and so does your ability to feel rested and alert.

Other causes include iron or vitamin B12 deficiencies, sleep disorders, insulin resistance, chronic inflammation, or low testosterone. Hormonal imbalances related to PCOS or adrenal issues can also quietly sap your energy.

For some, unrelenting fatigue is linked to blood sugar swings from unbalanced eating or early diabetes. And for others, mental health conditions like depression or high stress levels show up first in the body—as exhaustion.

When should you talk to a doctor about fatigue?

Everyone feels tired sometimes. But if your fatigue is ongoing, unexplained, and affecting your ability to focus, work, or enjoy life, it's time to take it seriously.

You should seek medical help if:

  • You feel tired every day, regardless of how much sleep you get
  • Your energy crashes during the day and doesn't bounce back
  • You've also noticed weight changes, low mood, or brain fog
  • You have trouble concentrating or feel unusually sluggish
  • You rely heavily on caffeine or sugar just to get through the day

These signs suggest a medical root cause—and getting clarity can be life-changing.

How Meto Can Help

At Meto, we take a root-cause approach to persistent fatigue. We begin with comprehensive lab testing to check for common contributors to low energy—such as thyroid dysfunction, vitamin B12 or iron deficiency, insulin resistance, cortisol imbalance, and other metabolic markers.

If we uncover a condition like hypothyroidism, low testosterone, or nutrient depletion, your matched specialist will create a treatment plan tailored to your needs. This may include medication, targeted supplements, or hormonal support.

Even if your labs are within normal limits, our clinical team—including nutritionists and health coaches—can work with you to improve energy through sleep optimization, blood sugar support, and stress management techniques.

You can start with a virtual consultation, making it easy to begin your journey without having to leave home.

Meto helps you go from drained to energized—with care that's built around what your body actually needs.
