An extreme sense of tiredness and lack of energy that can interfere with a person's usual daily activities.
A person with fatigue may feel weak, worn out, heavy, slow, or run down. They may also have trouble speaking or concentrating, short-term memory loss, and mood or emotional changes. There are many causes of fatigue, including anemia, poor nutrition, pain, anxiety, depression, sleep or thyroid disorders, and taking certain medicines. Fatigue may also be caused by cancer or cancer treatment. Certain types of fatigue, including cancer-related fatigue, may not be completely relieved by sleep and may last for a long time after treatment ends.

A medical examination with a physician to check for sign o illnesses or disease. Always make sure everything is fine before going to interface with lifestyle limiting factors.
Fatigue can be classified based on duration and underlying causes:
Acute Fatigue – Short-term exhaustion, often due to stress, poor sleep, or temporary illness.
Typically resolves with rest.
Chronic Fatigue – Persistent tiredness lasting 6+ months, potentially linked to medical conditions (e.g., anemia, thyroid disorders) or chronic fatigue syndrome (CFS).
Unlike normal tiredness, chronic fatigue isn’t fully relieved by sleep.
Since fatigue has many causes, doctors may recommend:
Blood tests (checking for anemia, thyroid issues, or vitamin deficiencies).
Sleep studies (if sleep apnea is suspected).
Nutritional pattern (for regiments high in caloreis low in nutrients)
Mental health screenings (for anxiety/depression).
Chronic fatigue syndrome (CFS) diagnosis requires ruling out other conditions and meeting specific criteria
(e.g., unexplained fatigue lasting ≥6 months).
Small adjustments can significantly boost energy:
1. Nutrition & Hydration
Eat iron-rich foods (spinach, red meat) if anemia is a factor.
Balance blood sugar with protein + complex carbs (e.g., nuts + whole grains).
Avoid energy crashes by limiting sugar and caffeine.
Stay hydrated—even mild dehydration worsens fatigue.
2. Sleep Optimization
Stick to a schedule (7–9 hours nightly).
Limit screens before bed (blue light disrupts melatonin).
Try relaxation techniques (deep breathing, meditation).
3. Stress & Mental Health
Practice mindfulness to reduce stress-related fatigue.
Therapy or counseling if emotional exhaustion is a factor.
4. Gentle Movement
Light exercise (walking, yoga) improves circulation and energy.
Avoid overtraining—excessive workouts can worsen fatigue.
Consult a healthcare provider if fatigue:
- Lasts longer than 2 weeks despite lifestyle changes.
- Includes unexplained weight loss, fever, or night sweats.
- Interferes with work, relationships, or daily tasks.
Fatigue stems from physical, emotional, or medical causes.
Chronic fatigue requires medical evaluation to rule out underlying conditions.
Lifestyle tweaks (sleep, diet, stress management) often help.
