Answer 1

pathophysiology is the study of disease. and cardiomegaly is a condition of an enlarged heart.

http://www.mayoclinic.com/health/enlarged-heart/HQ00623
Cardiomegaly is abnormal enlargement of the heart. It's not a disease, but a sign of an underlying problem. Many conditions can cause an enlarged heart, including:

High blood pressure
Heart valve disorders
Weakness of the heart muscle (cardiomyopathy)
Severe anemia
Thyroid disorders
Excessive iron in the body (hemochromatosis)
Abnormal protein buildup in an organ (amyloidosis)
In some people, an enlarged heart causes no signs or symptoms. Others may have:

Breathing difficulties
Shortness of breath
Dizziness
Abnormal heart rhythm (arrhythmia)
Swelling (edema)
An enlarged heart may be found incidentally on a chest X-ray done for some other reason. A doctor can confirm a diagnosis by an ultrasound of the heart (echocardiogram). Treatment is directed at the underlying cause.

Heart failure may cause bilateral peripheral edema, and should be considered first in a patient with known hypertension or coronary artery disease. Associated symptoms are dyspnea on exertion, orthopnea, and paroxysmal nocturnal dyspnea. On physical examination there may be pulmonary rales, distended neck veins, tachycardia, cardiomegaly, or gallop. Diagnostic studies to rule out heart failure include a chest radiograph and echocardiogram

Here is a diagram on atheromatous plaque build up in arteries. It shows a lot more detail about it: ca.answers.yahoo.com/

Here is a website on the pathophysiology: It talks about what is found in the tissues that makes muscles weak, etc. I hope some of this helps you a little. http://www.pompe.com/healthcare/overview/pathophysiology/pc_eng_hc_overview_pathophysiology.asp

Answer 6

Cardiomegaly literally means an enlarged heart which could be due to multiple etiologies such as hypertension, heart attack, valve disease etc. In your case it sounds like it is from your hypertension. Thick of your blood vessels as very narrow pipe with a narrowed diameter which has increased resistance and would need increased force to pump blood through it. Overtime, your heart develops a compensatory mechanism the left ventricle may enlarge hence you may heart the term "left ventricular hypertrophy (LVH)" it will eventually involve the other chambers of the heart. The key is to treat the underlying cause and minimize damage to the heart.

Answer 7

The most obvious are: abnormal protein buildup in the organ( Atkins diet); Excessive iron in the body or anemia; Heart valve disorders or weak heart muscle and hypertension. Cardiomegaly is not a disease..but a sign of another problem.

Answer 9

Making dietary changes is your first line of defense in treating hypothyroidism. Learn here https://tr.im/2rUcg

Many people with hypothyroidism experience crippling fatigue and brain fog, which prompts reaching for non-nutritional forms of energy like sugar and caffeine. I’ve dubbed these rascals the terrible twosome, as they can burn out your thyroid (and destabilize blood sugar).

1. Just say no to the dietary bungee cord. Greatly reduce or eliminate caffeine and sugar, including refined carbohydrates like flour, which the body treats like sugar. Make grain-based carbohydrates lesser of a focus, eating non-starchy vegetables to your heart’s content.

2. Up the protein. Protein transports thyroid hormone to all your tissues and enjoying it at each meal can help normalize thyroid function. Proteins include nuts and nut butters; quinoa; hormone- and antibiotic-free animal products (organic, grass-fed meats, eggs, and sustainably-farmed fish); and legumes.
