Cholesterol
is a building block of cells, vitamins and hormones
in the body. The human body makes cholesterol in
all cells of the body and also gets cholesterol
from some foods in the diet. It is transported in
the bloodstream to other cells or for elimination
by the body.
Cholestrol is a solid fat carried in blood by lipoproteins
and deposited in the walls of arteries which therefore
narrow and when they block completely cause heart
attacks and strokes .
Diet
and liver are two main sources of cholestrol . Low
cholestrol is not a danger as cells can make . Statins
cut production of cholestrol by inhibiting hmcoa.
Its better to add ezetrol than double statins.
Cholestrol
is a compound which if it gets into the arterial
vessel wall causes it to narrow and eventually block
completely if a clot forms on top leading to death
of muscle eg the heart area supplied by that artery.
It is made in the liver 50% , then secreted into
bile and absorbed via the gut 30% together with
that eaten in the diet eg egg yellows . It is attached
to ldl - a protein in the liver and in this form
can get into the vessel walls . Another protein
hdl takes it up from the vessels and takes it to
the liver to be broken down. So it follows that
too much cholestrol , too much ldl or too little
hdl are all bad
