Persistent tiredness, excessive daytime sleepiness, and lack of energy despite adequate night sleep can occur due to several reasons such as anemia,
vitamin B12 or
vitamin D deficiency,
thyroid disorders, stress, depression, poor sleep quality (including sleep apnea), inadequate physical activity, or other medical conditions.
I would advise getting the following investigations done:
•
Complete Blood Count (CBC)
• Thyroid Profile (
TSH)
• Vitamin B12 level
• Vitamin D level
•
Fasting Blood Sugar
Until then, maintain a regular sleep schedule, stay well hydrated, eat a balanced diet, exercise regularly, and avoid excessive screen time.
Next Steps
Consult a physician for clinical evaluation and review of the above reports. Treatment depends on the underlying cause, so medication should not be started without proper assessment.
Health Tips
Seek medical attention promptly if you have significant weight loss, fever, breathlessness, snoring with daytime sleepiness, or worsening fatigue.
