Hello! Welcome and thank you for asking on HCM! I understand your concern, and would explain that your symptoms may be related to a metabolic disorder. Low blood pressure and anxiety could also mimic this clinical scenario. Your systolic blood pressure seems to be slightly low. I recommend consulting with your GP for a careful physical examination, a resting ECG, a chest x ray study and some blood lab tests: - complete blood count (chronic anemia) - PCR, sedimentation rate (inflammation) - fasting glucose (for hypoglycemia) - thyroid hormone levels (thyroid gland function) - cortisol plasma levels (adrenal gland function) - kidney and liver function tests - blood electrolytes. A head up tilt test is necessary to rule in/out a possible orthostatic hypotension. If all the above tests, result normal, the main cause of your symptomatology would be just anxiety. Meanwhile I recommend taking plenty of water and juices to avoid dehydration. Hope to have been helpful! Best regards, Dr. Iliri
