Chlorine is a chemical element in the body and its blood level is called serum chloride and generally ranges between 95 and 107 mmol.l. It enters the hydration mechanisms of the body and plays a role in digestion
. Chlorine is supplied in the diet, mainly through table salt, and plant and animal products. The excessive presence of chlorine in the blood, called hyperchloremia, can be seen in cases of dehydration. A chlorine deficiency
, on the other hand, called hypochloremia, may be due to kidney failure or digestive losses. The variations of serum chloride are not worrying in their own right, but their cause should be investigated and treated.
