Thanks for the your question on HCM. I can understand your problem and situation. In my opinion you are having breathing difficulty due to anaemia. Hot flushing can also be seen in anaemia. So correction of anaemia should be done in your case. You are also having hormonal imbalance. So possibility of anxiety related mood swings and breathing difficulty is also high. Hormonal imbalance is known to cause anxiety. So anaemia and anxiety both are causing you breathing difficulty. Your age is too young for cardiac cause. So no need to worry much for cardiac cause. Better to consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. Correction of anaemia and hormonal imbalance is needed. So consult your gynecologist and start appropriate treatment.
