YOU WANNA HAVE THOSE BONES THAT ARE DIE HARD?...well!all that u have to do is to make sure that you consume enough calcium everyday.I will mention a case that has come to my hospital the other day.It happened right in front of my hospital.A kenyan{black} was dead drunk and met with an accident.He collided with a car and that was a head on collision.He somersaulted in air and fell behind the car.All the people over there expected him to have greivous injuries and polytrauma.But man!..surprsingly the fellow did not have a single fracture neither a head injury.IT WAS MIRACLE THOUGH.,but i attribute it to his strong bones.
Though few races are gifted with bones like that we all can make our bones tougher if only we consume calcium in adequate quantities.
The aim of this review is primarily to put in front of u the role that calcium plays in our metabolism and the defects that can result due to its deficiency.
THE USES:The uses of calcium are many.I am mentioning only the most important of them here.Calcium is a bone builder.It is one of the most important ingredient of the ground substance in a bone that provides the bone a specific structure and stability.The most important use of calcium is in OSTEOPOROSIS.Osteoporosis is a disease of bones where in the bones get fragile.THE INCIDENCE OF FRACTURES ARE THUS MORE IN AN OSTEOPOROTIC PATIENTS.Osteoporosis is more common in post-menopausal women thogh men are also susceptible.The underlying basis of post-menopausal osteoporosis is withdrawal of oestrogen harmone from the blood which maintains the serum calcium levels.As such when the blood calcium falls the only way is the mobilisation of calcium from the bones in to the blood,thus making the bones fragile.The remedy for this is to maintain the blood calcium levels in the blood and we all can do it by supplementing calcium tablets to our diet.
Calcium has also been implicated in reduction of the blood cholesterol.
..there by it reduces the incidence of myocardial infarction and strokes.
Calcium is also a necessary co-factor in the clotting pathway.
Calcium deficiency in children causes a disease called rickets that produces a variety of deformities.This especially occurs in children who are kept covered and not exposed to sunlight.SUNLIGHT is a natural source for calcium and we can acqire enough calcium by just exposing ourselves to the sunlight.
HYPOCALCEMIA can lead to TETANY a disorder of muscle contraction.
Calcium is also used in prevention of kidney stones.But excess calcium on the other hand can produce calcium gall stones and renal calculi.
Calcium is also preventive in some cancers like colonic carcinomas.
THE R.D.A:the required daily allowance of calcium is 1000 to 1500mg.
THE NATURAL SOURCES:CALCIUM is abundantly presnt in green leafy vegetables and dairy products.MILK is the best source.
THE SUPPLEMENTS:i recommend that every one take calcium in doses of 500 to 1000mg per day in order to prevent osteoporosis.This is particularly recommended for women.The calcium supplements are available in the form of chewable tablets .These are tasty and pallatable with all age groups.They are also available in the form of oral swallowable tablets and in the form of syrups.
THE ADVERSE AFFECTS:excess calcium can cause gall stones and kidney stones.constipation is also seen.
THE INTERACTIONS: make sure that u do not take antacids and calcium together becuase it forms complexes with antacids.
I hope this review provides with all the necessary information regarding calcium .If u want further deatails please do post a comment.As a doctor it is my pleasure to serve you.
