Hello! Thank you for asking on HCM! I understand your concern, and would explain that your symptoms seem to be related to a metabolic disorder. A comprehensive differential diagnosis between different disorders like chronic anemia, thyroid gland dysfunction, adrenal gland dysfunction or a vitamin deficiency should be done. Depression could also mimic this clinical scenario. I recommend consulting with the GP for a careful physical examination and perform a resting ECG, a chest x ray, an abdominal ultrasound and some blood lab tests: - complete blood count ( for chronic anemia) - inflammation tests ( fibrinogen, PCR, sedimentation rate) - thyroid hormone levels - cortisol plasma levels - blood lipid profile - fasting glucose - blood electrolytes - kidney and liver function tests, etc. You should consult with your GP on the above issues. Hope to have been helpful! Best wishes, Dr. Iliri
