Low in the body fluid may be the cause of:
tetany
anaemia
angina pectoris
gout
Anemia is caused when the iron is deficient in the body. If there is an excess of uric acid in the blood it leads to the formation of gout. Angina pectoris is a coronary artery disease. Low Ca++ ions lead to tetany. In this condition, there is an involuntary contraction of the muscles.
