#2 Difficulty in breathing
You may face the lack of breath, like not having enough air when you have a heart condition. This happens because the heart is unable to pump the right amount of blood in your lungs, supplying them with the needed quantity of oxygen. So here is why you will feel like looking for more air. Most commonly, this happens in the evening or when laid on the back. Sitting up or having a support in your back may help you breathe more easily. Still, if you are experiencing these signs rather often, do get checked out.
