Blood urea nitrogen ( BUN ) is a medical test that measures the amount of urea nitrogen found in blood. Urea is a waste product formed in the liver when protein is metabolized into its component parts (amino acids). This process produces ammonia, which is then converted into the less toxic waste product urea. Blood urea nitrogen or BUN test measures the amount of urea nitrogen in the blood.
Nitrogen is a component of both ammonia and urea. Urea and urea nitrogen are referred to somewhat interchangeably because urea contains nitrogen and because urea/urea nitrogen is the "transport method" used by the body to rid itself of excess nitrogen. Urea is released by the liver into the blood and is carried to the kidneys, where it is filtered out of the blood and released into the urine. Since this is an ongoing process, there is usually a small but stable amount of urea nitrogen in the blood.
Most diseases or conditions that affect the kidneys or liver have the potential to affect the amount of urea present in the blood. If increased amounts of urea are produced by the liver or if the kidneys are not working properly and have difficulty filtering wastes out of the blood, then urea concentrations will rise in the blood. If significant liver damage or disease inhibits the production of urea, then BUN concentrations may fall.

BUN or Blood Urea Nitrogen test is prescribed to evaluate:
Blood urea nitrogen levels can also help identify damage to body systems and diseases of the digestive, circulatory, and respiratory systems.
BUN or Blood Urea Nitrogen test is part of both the BMP and CMP, groups of tests that are widely used:
Some signs and symptoms of kidney dysfunction include:
BUN or Blood Urea Nitrogen test also may be ordered:
Triglycerides are the most common type of fat in your body. You get some from the food you eat, and your body makes some. Your levels of triglycerides may also be high with other conditions such as diabetes, pre-diabetes, or heart problems such as high blood pressure. If you?re overweight and have a large waistline, you?re also at risk for high levels. Your triglycerides are more likely to be high if you have one or more of these health issues: high levels of LDL -- the ?bad? cholesterol -- or low levels of HDL - the ?good? cholesterol.
Cholesterol is a waxy, fat-like substance that occurs naturally in the body and is made by the liver. Cholesterol is also present in foods we eat. People need cholesterol for the body to function normally. Cholesterol is present in membranes (walls) of every cell in the body, including the brain, nerves, muscles, skin, liver, intestines, and heart. too much cholestrol is dangerous to health heart
Take note that testing equipment like blood glucose meters, which can be bought over the counter, cannot diagnose diabetes. You should consult a physician to get a proper diagnosis.
Yes, but fruits should be consumed in moderation, as some contain high amounts of fructose that can severely affect your blood sugar levels.
The hormone that helps the body use sugar (glucose) for energy is called insulin.
Insulin is made by the body in the pancreas and when the body cannot produce enough insulin on its own, it needs to be taken by injection or other means.
Everyone who has type 1 diabetes (previously known as juvenile diabetes) must take some form of insulin therapy. Some people with type 2 diabetes will also need insulin supplementation. There are different types of insulin available, and they differ in chemical structure and how long they last in the body
Triglycerides are lipids. They are a main component of fat and are used to store energy. They circulate in the blood so that your body can easily access them.
Your blood triglyceride levels rise after you eat food. They decrease when you?ve gone a while without food.
Extreme thirst, Frequent urination and Fatigue. Symptoms of type 2 diabetes are related to high blood sugar levels (hyperglycemia).
Symptoms may not be present at first because type 2 diabetes can develop gradually over time. High blood sugar levels can result in symptoms including thirst, frequent urination, tiredness, listlessness, nausea, and dizziness. If the blood sugar levels are extremely high, symptoms may escalate to confusion, drowsiness, and even loss of consciousness (diabetic coma, which is a medical emergency).
