Low blood pressure, also known as Hypotension , can, in rare cases be a sign of underlying disease, but most of the time it is something to be grateful for. However, one form of temporary low blood pressure can cause lightheadedness. Known as orthostatic hypotension, it occurs when you stand up suddenly.
Your cardiovascular reflexes work quickly to prevent blood from pooling in your ankles and legs, but a too rapid change in position may tax these reflexes, especially in older people.
Glucose: A sugar
that is the simplest form of carbohydrate. It is commonly referred to as
blood sugar. The body breaks down carbohydrates in foods into glucose, which
serves as the primary fuel for the muscles and the brain. Excess glucose is
either converted by the liver to glycogen or turned into body fat.
Cholesterol: A
waxy, fat-like substance manufactured in the liver and found in all tissues.
In foods, only animal products contain cholesterol. An excess of cholesterol
in the bloodstream can contribute to the development of atherosclerosis.
HDL
Cholesterol: High Density Lipoprotein - A transporter of cholesterol
from the artery walls to the liver. HDL's help the liver excrete cholesterol
as bile, a liquid acid essential to fat digestion. For this reason, HDL is
called "good" cholesterol.
Triglycerides:
The main form of fat found in foods and the human body. Containing three
fatty acids and one unit of glycerol, triglycerides are stored in adipose
cells in the body, which, when broken down, release fatty acids into the
blood.
Ketone:
Relatively reactive organic compounds that serve as important intermediates
in cell metabolism. The simplest ketone, acetone, is a product of the
metabolism of fats and usually oxidizes quickly to water and carbon dioxide.
In diabetes, however, this ketone accumulates in the body and may be detected
in the urine.
