Hello! Thank you for asking on HCM! Regarding your concern, I would explain that your symptoms may be related to a metabolic disorder or a chronic infection. I recommend consulting with your GP for a careful physical examination, a resting ECG, a chest x ray and some lab tests: - complete blood count (for chronic anemia) - blood fasting glucose - kidney and liver function tests - blood electrolytes - PCR and sedimentation rate - blood and urine osmolarity - cortisol plasma levels (for the adrenal gland function) - urine analysis and urine bacterial culture. Meanwhile I would advise to closely monitor your blood pressure (for possible hypotension), take plenty of fluids (water and juices) and avoid straining physical activity. Hope to have been helpful! Best regards, Dr. Iliri
