Dr. Pan found that one possible reason for chewing ice was due to iron deficiency. Iron deficiency can cause a burning sensation in your mouth, leading to a craving(called Pica) for ice. Pica is a craving for any substance that has no nutritional value, and has other causes, but Dr. Pan was interested and concerned about the iron deficiency because it can cause other systemic issues. Iron deficiency can cause low red blood cell count(anemia), frequent infections due to suppressed immune system, hair loss, and extreme fatigue or exhaustion. Low iron has also been linked to a much higher rate of oral infection and dry mouth
So, if you find yourself chewing ice constantly, it is Dr. Pan's recommendation that you speak to your primary care physician regarding having a possible iron deficiency. It is much easier to get a simple test done and protect yourself from a number of preventable complications. Also a lot easier on the checking account!
