Feeling tired all the time is frustrating. For many people in St. Louis, fatigue has become part of daily life.
You push through work. You manage family responsibilities. Yet the exhaustion never goes away.
Persistent fatigue is not normal. It often signals an underlying medical issue.
Understanding the causes of fatigue and when to see a doctor can help you regain your energy and improve your health.
What Is Fatigue?
Fatigue goes beyond feeling sleepy. It is a constant lack of energy that does not improve with rest.
Many patients describe it as:
- Mental fog
- Low motivation
- Physical weakness
- Difficulty concentrating
7 Common Causes of Fatigue
1. Anemia (low blood count)
Low blood counts reduce oxygen delivery in your body. This can cause
- Weakness
- Shortness of breath
- Pale skin
Women and frequent blood donors are at higher risk.
2. Hormone Disorders
An underactive thyroid, low testosterone, or low estrogen levels can drain your energy.
Symptoms include:
- Weight gain
- Cold intolerance
- Fatigue
- Poor sleep
- Low libido
3. Poor Sleep Quality
You may be sleeping enough hours, but not getting restful sleep.
Causes include:
- Sleep apnea
- Stress, anxiety, or depression
- Screen time before bed
4. Vitamin Deficiencies
Low levels of:
- Vitamin B12
- Vitamin D
can lead to low energy and brain fog.
5. Chronic Stress
Stress affects hormones and sleep cycles.
Over time, it drains your energy reserves.
6. Depression and Anxiety
Mental health conditions often present as fatigue.
This is frequently overlooked.
7. Chronic Medical Conditions
Conditions such as:
- Diabetes
- Heart disease
- Autoimmune disorders
can cause ongoing fatigue.
