Hello! Welcome on HCM! I carefully passed through your question and would explain that her symptoms seem to be related to chronic anemia. Nevertheless, other possible causes should be excluded too: - cardiomyopathy - thyroid dysfunction - electrolyte dysfunction, etc.. That is why I would recommend performing further tests: - a cardiac ultrasound - thyroid hormone levels - blood electrolytes. Hope you will find this answer helpful! Meanwhile, I would recommend taking plenty of fluids and avoid physical exertion or prolonged standing up position, which could lead to falling. Hope to have been helpful! Wishing all the best, Dr. Iliri
