they cause you to put your homework questions in the wrong category. pot-belly pigs?

Blood clots, now you answer one of my homework questions.

Blood clots and possible leaking of blood.

All three can cause slight dizziness, fatigue and paleness of the skin.

mitral valve prolapse is where the mitral valvae is prolapsing or falling into the heart chamber. this is a genitic disease. mitral valve stenosis is a hardening of the mitral valve aortic regurgetation is where the blood flows is two different directions. as the blood is moving our through the valve some of it is brought back into the heart by the valve. any and all of these conditions can be dangerous. it is best to see a doctor to get the correct diagnosis and treatment.

any one of these could be dangerous and you ought to have them checked out immediately, if not sooner!!! if all three are together, you'll experience a lot of anxiety, blood falling back on itself with nowhere to go.

From the Mayo clinic: * Mitral valve prolapse. Mitral valve prolapse is a condition in which the leaflets and tendon-like cords supporting the mitral valve weaken. The result is that with each contraction of the left ventricle, the valve leaflets bulge (prolapse) up into the left atrium. This common heart defect may prevent the mitral valve from closing tightly and lead to regurgitation. However, mitral valve prolapse is common and most people who have it never develop severe regurgitation. * Damaged tissue cords. Mitral valve regurgitation may result from damage to the tissue cords that anchor the flaps of the mitral valve to the heart wall. Over time, these cords may stretch or suddenly tear, especially in people with mitral valve prolapse. A tear of these cords can cause substantial leakage through the mitral valve and may require repair by heart surgery. * Rheumatic fever. Rheumatic fever — a complication of untreated strep throat and once a common childhood illness in the United States — can damage the mitral valve, leading to mitral valve regurgitation later in life. Rheumatic fever can damage the mitral valve in two main ways. The infection may cause the leaflets of the valve to thicken, limiting the valve's ability to open. This results in narrowing of the valve, a condition known as mitral valve stenosis. The infection may also cause scarring of the mitral leaflets, leading to regurgitation. People with rheumatic fever, which is still common in countries where antibiotic use isn't common, may have both mitral valve stenosis and mitral valve regurgitation. * Endocarditis. The mitral valve may be damaged by endocarditis, an infection of the lining (endocardium) of the heart that can involve heart valves. * Deterioration of the valve with age. The mitral valve opens and shuts tens of thousands of times every day of your life. Sometimes age-related wear and tear on the valve causes mitral valve regurgitation. * Prior heart attack. A heart attack can damage the area of the heart muscle that supports the mitral valve, affecting the function of the valve. In fact, if the damage is extensive enough, a heart attack may result in sudden and severe mitral valve regurgitation. This sudden onset of regurgitation is sometimes referred to as acute mitral valve regurgitation. * Untreated high blood pressure. Over time, high blood pressure can cause your heart to work harder and gradually your heart's left ventricle can enlarge. This can then stretch the tissue around your mitral valve, which can lead to leakage. * Congenital heart defects. Some babies are born with defects in their heart, including damaged heart valves. Severe mitral valve regurgitation — regardless of its cause — can weaken your heart. When the left ventricle contracts in a heart with mitral valve regurgitation, some blood flows backward into the left atrium instead of flowing forward into the aorta. As a result, blood flow to the rest of your body decreases. In response, the left ventricle may enlarge so that it can pump more blood with each heartbeat. At first this adaptation helps your heart beat with more force. But eventually, the change weakens your heart and may cause heart failure and heart rhythm irregularities, such as atrial fibrillation.
