Valencia Medical Center | Valencia, CA
It’s a common story we hear at Valencia Medical Center: “I’m always tired, and I don’t know why.” You’re in your 40s, juggling family, work, aging parents, and maybe even starting to think about your own long-term health. But despite getting what seems like enough rest, you wake up tired, feel drained by midday, and crash in the evening. Sound familiar?
If you’re feeling unusually fatigued in your 40s, it’s not “just getting older.” Your body is sending you important signals—and we’re here to help you understand what they mean and how to take action.
Common Reasons You’re Tired in Your 40s
1. Hormonal Changes
As you approach midlife, your hormone levels begin to shift. For women, this may mean the transition into perimenopause or menopause, with drops in estrogen and progesterone. For men, testosterone levels may decline gradually—a condition known as andropause.
Symptoms of hormonal imbalances can include:
- Fatigue
- Sleep disturbances
- Mood swings
- Brain fog
- Weight gain
2. Thyroid Dysfunction
Thyroid hormones regulate metabolism. Even a slight underperformance of the thyroid (hypothyroidism) can lead to chronic fatigue, weight gain, and sensitivity to cold.
3. Nutrient Deficiencies
In your 40s, your body may absorb nutrients less efficiently. Deficiencies in vitamin B12, vitamin D, iron, and magnesium are common causes of tiredness and lack of energy.
4. Poor Sleep Quality
Even if you’re in bed for 7-8 hours, it doesn’t always mean you’re getting quality sleep. Sleep apnea, stress, hormonal fluctuations, or even screen time before bed can all disrupt restorative sleep cycles.
5. Chronic Stress & Adrenal Fatigue
Juggling the responsibilities of midlife often causes prolonged stress, which overworks your adrenal glands. The result? A constant sense of fatigue and burnout.
6. Blood Sugar Imbalances
Skipping meals, eating too many processed carbs, or insulin resistance can lead to dips and spikes in blood sugar—leaving you drained and craving more caffeine or sugar.

Q&A: Fatigue in Your 40s
Q: Is it normal to feel more tired as I age?
A: Some changes in energy are expected with age, but persistent fatigue is not normal. It’s often a sign of a deeper issue such as hormone imbalance, nutrient deficiencies, or chronic stress.
Q: What kind of lab tests should I get if I’m feeling fatigued?
A: We recommend checking your thyroid panel, vitamin B12, vitamin D, iron/ferritin levels, cortisol levels, and sex hormones like estrogen, progesterone, and testosterone.
Q: Can fatigue be caused by stress alone?
A: Yes. Chronic stress impacts your adrenal glands and can lead to cortisol imbalances that result in exhaustion, anxiety, and even insomnia.
Q: I’ve had normal labs from my primary care doctor. What now?
A: Many traditional lab panels don’t go deep enough. At Valencia Medical Center, we use comprehensive functional lab testing that looks at optimal—not just “normal”—ranges, helping us catch early imbalances often missed in routine checkups.
Q: How soon can I expect to feel better?
A: With the right treatment plan, many patients start feeling improvements in energy and mood within a few weeks. Full restoration of vitality may take a few months, depending on the underlying causes.
