How
does cholesterol affect the body?
A
person's blood cholesterol level is influenced by two factors. One
is the saturated fat and cholesterol a person eats. The second is
how much cholesterol his or her body makes. Cholesterol is made
in the liver.
Cholesterol
is a part of every cell in the body. It has some valuable functions
in the body. It is used to make certain hormones and bile, which
is needed for digestion of fat. Sunlight can help a substance containing
cholesterol in the skin change to vitamin D.
The body produces
all the cholesterol it needs. When too much cholesterol is consumed,
the body cannot get rid of the excess. Cholesterol can build up
on the insides of blood vessel walls. This results in atherosclerosis,
or hardening of the arteries. LDL cholesterol is the main source
of buildup on the blood vessel walls. HDL carries cholesterol back
to the liver and can prevent buildup on the blood vessel walls.
Cholesterol
is a significant factor in the development of coronary
heart disease.
