Excerpted from: Buzzle.com ~ If the bodily calcium requirements are not met, it could lead to osteoporosis, hypertension and other problems. Any kind of bony structure in our body can be weakened due to calcium deficiency. If there is an increase in the levels of calcium it results in fatigue, nausea, anorexia, constipation, depression or increased urination. It can also result in the formation of kidney stones. So to avoid the deficiency or the increased level of calcium, we need to take care that we do not consume too much of this mineral either through foodstuffs or calcium supplements. A healthy diet involves a good amount of calcium rich foods.
