Hello,
A few conditions where you may experience severe fatigability are medications, such as antihistamines, cough medicines, not enough sleep, unhealthy eating habits, acute liver failure, anemia, anxiety disorders, cancer,
chronic fatigue syndrome, chronic infection or inflammation, chronic kidney disease, concussion, COPD (chronic
obstructive pulmonary disease) worsening of symptoms, depression (
major depressive disorder) or other mood disorders, diabetes, emphysema, fibromyalgia, grief, heart disease, hyperthyroidism (overactive thyroid), hypothyroidism (underactive thyroid), and
inflammatory bowel disease (IBD).
Detailed clinical examination and few investigations like complete blood picture, hemoglobin percentage, blood sugar levels, liver function tests, kidney function tests,
thyroid function tests, HbA1c, and peripheral smear. Please do consult a physician for detailed clinical examination and for specific diagnosis and appropriate treatment.
Take care. Hope I have answered your question. Let me know if I can assist you further.
