@nafoyo Hi and im not sure if I can add anything but the only symptom that I had and what it can cause might help. When I had a low ef it has the potential to cause fluid retention. You see the heart has a duel purpose besides pumping blood it also pushes fluid that collects in the lungs into the urine tract to get rid of it. When the heart is weaker it is less affective in pushing on the lungs to accomplish this. So most people with heart failure due to low ef need to be on diuretics and for me it was a daily weight in that I could tell if I was retaining to much fluid by sharp increases in weight. This after getting used to what dose I would take would prompt me adjust the diuretics based on it. But like Teresa said it takes time and under a cardiologist guidance can be achieved. But you may ask about that at your next Cardiology visit. I know when I would retain to much it makes you a bit more sluggish and if it builds up around your Heart can really cause problems. That's how I found out. So I hope that may help. I am.also curious what other symptoms you may experience.
Have a Blessed Day
