Hello! Welcome and thank you for asking on HCM! I understand your concern and would explain that anxiety could cause these changes in blood pressure. A metabolic disorder (like thyroid dysfunction or adrenal dysfunction) could cause this sympyomatology too. 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 -thyroid hormone levels -cortisol and aldosteron plasma levels -blood electrolytes -kidney and liver function tests -fasting glucose. If all the above tests result normal, the main cause of your problems would be a generalized anxiety disorder. In such case you should consult with a specialist of this field, to help you manage your anxiety. Psychotherapy, anxiolytics and an antidepressant may be necessary. Hope to have been helpful! Best wishes, Dr. Iliri
