Blood gets its red color from?

Urine is a transparent solution that can range from colorless to amber but is normally a pale yellow. In the urine of a healthy person, the color comes yellow from the presence of a product called urobilin. Urobilin is the final waste product resulting from the breakdown of heme from hemoglobin during the destruction of aging blood cells in the body.

Colorless urine can indicate over-hydration, which is usually considered much healthier than dehydration. Ina dehydrated person the urine colour will be very dark or even seem brown. However, over-hydration can remove essential salts from the body so there is a fine balance.

Do you have to fast for hemoglobin blood test?

No. The A1C test measures the amount of glucose bound to hemoglobin in the red blood cells. This binding process is related to the concentration of glucose present and the time of exposure. New cells are constantly created to replace old cells that are removed. Thus, the test meaures an average value of the glucose exposure over the life of the red blood cell (about 4 months). So, a one-day change, due to fasting for example, represents only a small change (one day in 120 days). For convenience, the doctor may have A1C run on blood drawn at the same time for other tests that DO require fasting. But, the nature of A1C should not require it.

Why is high blood sugar bad?

Sugar per se is not bad for health. A healthy person will be able to take care of all the sugar he or she eats. All food that we eat is converted to sugar in body. Body uses this sugar for its energy needs and extra sugar is converted in fat and stored in adipose tissue for a rainy day. Thus when you consume more calaories than you utilize for your activities or exercise you will gain weight. It does not matter if calories have come from sugar or not. A person with diabetes finds it difficult to tackle the sugar intake as fast as a normal person will do and hence blood sugar levels of a diabetic person will remain high for a much longer time than blood levels of a normal person.

What are things that could affect the specific heart structures that in turn cause a malfunction in the flow of blood through the heart or body?

There are many causes for heart malfunction. Firstly, consult with a cardioligist !

An atrial fib, could cause irregular heart beat function and create a clot. Plaque could break away from any artery in the body ( Watch out for undiagnosed leg pain, arm pain...extremity pain. Have your carotid arts, checked for flow. A loosened bit of plaque could end your life. If you cannot tolerate any of the statin drugs, such as Crestor, even the use of very small quantities may prevent plaque from straying in the arterial system. Slowly, increase the intake of the drug even over a month or two. In some cases I understand the body will begin to acclimate itself to the drug intake. Go slowly at first. 2.5 mg's is plenty to start. These statin drugs last a long time and they will not lose their effectiveness for a long time even when split up into bits. Always consult with your doc. before beginning any kind of regimen. The heart is a very complicated organ as you well know. I have lived to 80 years old and still counting after a 5 stage bypass which was given to me after I insisted on a stress test and after being told all was ok! I avoided a surefire deadly heart attack by using my own intuitive reasoning ( I was without pain but something told me to check it out, fatigue was one symptom). Don't dispair. Many great things are being worked on even as I type the epistle. Get checked. Insist on a stress test. If you are unable to walk or run other tests are available to check on plaque buildup. Good luck. Listen to your body. Find a doctor who takes a keen interest in getting you to feel better. It's not always about living a long time; it's about the quality of your life and what you will be capable of doing to be feeling the best you can be. The bypass took place 16 years ago.
