When you have heart failure, your heart may not be strong enough to pump out as much blood as your body needs. As it tries to move more blood, your heart gets larger. It also pumps faster, and your blood vessels narrow to get more blood out to your body. As your heart works harder, it becomes weaker and the damage increases. Your body gets less oxygen, and you might notice symptoms like shortness of breath, swelling in your legs, and fluid buildup. Your body tries to keep the blood it has to supply your heart and brain. This leaves less for organs like your kidneys and liver. A lack of enough blood can damage these organs. You can't cure heart failure, but you can manage it by following your treatment plan. Medicines, diet, exercise, and surgery are just some of the treatments that doctor might suggest to prevent these problems. Please don"t neglect your heart problems ..
