An enlarged heart, also known as cardiomegaly, is a condition where your heart muscles bulge out more than they’re supposed to. This could interfere with your heart’s beating and pumping ability. While this is a treatable condition, it could be serious, so visit your doctor right away if you experience shortness of breath, heart fluttering or palpitations, and swelling throughout your body. [1] Your doctor will probably prescribe medications like ACE inhibitors or beta blockers to lower your blood pressure and restore your heart to its normal pumping ability. They will also give you some dietary and lifestyle instructions to follow. We’ve gone ahead and put together some of these health and lifestyle tips together to both help your heart heal and prevent it from enlarging again.
