I think it's supposed to suck up excess fats(which then are excreted..), which then can't go clogging your arteries. Not very scientific, sorry!
2 :
The most common cause of coronary heart disease (CHD) is the clogging of arteries, called atherosclerosis. The stuff that builds up on the inside of arteries is a fatty deposit, mostly made of cholesterol. Now, cholesterol is naturally made by the liver, and plays an important role in our health and wellbeing. It is when there is too much cholesterol in our system that problems start to occur. The digestion of fiber literally pulls the cholesterol out of the blood stream and into the digestive tract to help. That's it in a nutshell, but if you want more detailed info, here it is: http://health.howstuffworks.com/diseases-conditions/cardiovascular/cholesterol/foods-that-lower-cholesterol2.htm

i have no idea
3 :
Nonpolar triglycerides (fat) don't dissolve in water and can build up in the coronary arteries (the arteries around the heart that give the heart itself blood). The buildup is dangerous and can lead to heart disease.
4 :
Cholesterol and triglycerides, being NONPOLAR lipid substances (insoluble in water), need to be transported in the plasma associated with various lipoprotein particles. Plasma lipoproteins are separated by hydrated density; electrophretic mobility; size; and their relative content of cholesterol, triglycerides, and protein into five major classes: chylomicrons, very-low-density lipoproteins (VLDL), intermediate-density lipoproteins (IDL), low-density lipoproteins (LDL), and high-density lipoproteins (HDL). Since the levels of plasma lipids have a bell-shaped distribution in the general population, the definition of either a high or a low value of these substances has remained an arbitrary statistical decision. High values have been traditionally considered as those in the 90th and 95th percentiles; low values were considered to be those below the 5th percentile. The NIH Concensus Conference has recently revised the values concerning cholesterol, however, in view of clear evidence of an increased risk of coronary atherosclerosis in persons falling in the 75th to 90th percentiles. According to this last statement, cholesterol levels below 200 mg/dl are classified as "desirable blood cholesterol," those 200 to 239 mg/dl as "borderline-high blood cholesterol," and those 240 mg/dl and above as "high blood cholesterol

Hi, It's tough to know that your son has two conditions, that he will have for the rest of his life. But look, your son is among the lucky ones who have the right diagnosis, among those babies born everyday with no definite diagnosis of their disease... Talk to the doctor, he must have explained already these two conditions, g6pd babies, as you know, can live normally as long as they avoid food/medications that trigger the symptoms, and that some congenital heart disease patients have mild structural defects (asd,vsd, etc) and are asymptomatic. They can live long lives as long as they take care of their health. It's normal to worry, its human nature, because i know you love him and want the best for him. You'll do great! Nevertheless, remember that you have a growing baby boy, and no matter what conditions he may have, you do have one of life's greatest blessings. :)

I really don't think there is a way to ease your worries. My son has Congenital heart disease. He had to have open heart surgery when he was 11 days old. We spent 5 months in the hospital 4 of that in the ICU. He unfortunately went into cardiac arrest after his surgery and was placed onto life support. I was told to say goodbye to him twice. Everyday I worry that he won't wake up. The doctors have assured me that they are not concerned about his heart right now. But, that only gives a small amount of reassurance to a mother of a sick child. All I can say is it will start to get a little easier. My son is 9 months old now. I have had him home for 4 months. At first I couldn't even sleep in my bedroom. I slept with him in his swing and me right next to the swing on the couch. I would get up every hour or so just to see if he was pink and breathing. Slowly I moved his crib into my room and started sleeping in my own bed. The worry has slowly gone down. I still worry when he is down for a nap that I am going to walk into the room and find him blue and not breathing. I am not sure if that will ever go away. I hope so. I think for me it's going to take a long time
