What Does Chewing Ice Do for Anemic People?

4 min read

Chewing ice compulsively, a condition known as pagophagia, has a strong and well-documented association with iron deficiency anemia. While it may provide a temporary boost in alertness for those with anemia, it does not correct the nutritional deficiency and poses significant risks to dental health.

Quick Summary

Anemic individuals often experience pagophagia, an intense craving to chew ice, which research suggests provides a temporary mental boost by increasing blood flow to the brain. However, this behavior does not address the root cause of the iron deficiency and can cause serious dental damage over time.

Key Points

  • Symptom, not a cure: Chewing ice (pagophagia) is a symptom of iron deficiency anemia, not a treatment for it.

  • Temporary mental boost: The cold stimulus from chewing ice may temporarily increase blood flow to the brain, improving alertness in anemic individuals.

  • Significant dental risks: This habit can chip teeth, wear down enamel, damage dental work, and lead to jaw problems over time.

  • Resolves with treatment: Once the underlying iron deficiency is treated with supplements or diet, the craving for ice typically disappears.

  • Need for professional diagnosis: It is critical to consult a doctor for a proper diagnosis before attempting to treat a possible iron deficiency.

  • Safe alternatives exist: For those who crave the sensation, safer alternatives like frozen fruit, chilled vegetables, or sugar-free gum can help.

The Connection Between Chewing Ice and Anemia

Anemia, a condition where the body lacks enough healthy red blood cells, is most commonly caused by an iron deficiency. The red blood cells require iron to produce hemoglobin, the protein responsible for carrying oxygen to the body's tissues. When iron levels are low, oxygen delivery to the brain decreases, which can cause symptoms like fatigue, sluggishness, and poor concentration.

Pagophagia is a type of pica, an eating disorder defined by the compulsion to eat non-nutritive substances. The compulsive craving for ice is one of the most common forms of pica, particularly in individuals with iron deficiency. While the exact reason for this craving is still not fully understood, there are several prevailing theories:

  • Increased alertness: One prominent theory suggests that the cold from chewing ice triggers a response that increases blood flow to the brain, providing a temporary sense of alertness and mental clarity. A study published in Medical Hypotheses found that chewing ice significantly improved neuropsychological test performance in anemic individuals, but had no effect on non-anemic subjects.
  • Soothing effect on oral inflammation: Some researchers hypothesize that chewing ice may help soothe a sore or inflamed tongue (glossitis), a symptom commonly associated with iron deficiency anemia. The cooling sensation may provide relief from oral discomfort.
  • Psychological coping mechanism: In some cases, pagophagia can be a behavioral response to stress, anxiety, or obsessive-compulsive tendencies, though its link to nutritional deficiency remains stronger.

The Dangers and Damage of Chewing Ice

While chewing ice may seem like a harmless way to manage the temporary discomforts of anemia, it carries a significant risk of long-term damage, particularly to dental health. Dentists strongly advise against the habit, regardless of the underlying cause.

Risks associated with compulsive ice chewing:

  • Dental damage: The hardness and cold temperature of ice can cause teeth to chip, crack, or fracture over time. This can lead to expensive dental procedures like crowns or extractions.
  • Enamel erosion: Repeated chewing wears down tooth enamel, the protective outer layer of the teeth. This leaves teeth more vulnerable to decay, cavities, and heightened sensitivity to temperature changes.
  • Damage to dental work: Existing fillings, crowns, and other restorations can be easily damaged or loosened by the pressure of chewing ice, requiring costly repairs.
  • Jaw problems: The repetitive strain on the jaw muscles and joints can lead to temporomandibular joint (TMJ) disorders, causing pain, headaches, and stiffness.

Treatment and Alternatives for Anemic People

Addressing the root cause of pagophagia—the iron deficiency—is the most effective way to eliminate the ice craving. The craving for ice often resolves shortly after iron levels are restored through proper treatment.

Comparison of Iron Repletion Methods

Method Description Pros Cons
Dietary Changes Increasing intake of iron-rich foods such as red meat, poultry, leafy greens, and fortified cereals. Natural, long-term solution. Improves overall nutritional status. Can be slow to reverse deficiency. Requires consistent effort.
Oral Supplements Over-the-counter or prescription iron tablets. Effective, relatively low-cost treatment for most cases. Can cause gastrointestinal side effects like constipation or nausea. Slow absorption.
Intravenous (IV) Iron Iron delivered directly into the bloodstream through an infusion. Rapidly restores iron levels, useful for severe cases or malabsorption issues. Bypasses GI side effects. Higher cost, requires medical supervision, potential for adverse reactions.

For those who crave the sensation of chewing, several safer alternatives can help manage the habit while iron levels are being corrected:

  • Frozen fruits: Grapes or berries can provide a satisfying cold crunch.
  • Crunchy vegetables: Chilled carrot sticks or cucumber slices offer a similar texture without damaging teeth.
  • Sugar-free popsicles: These can satisfy the need for a cold treat.
  • Crushed or shaved ice: Softer forms of ice are less damaging than hard cubes.
  • Sugar-free gum: Keeps the mouth occupied and stimulates saliva production.

What to Do If You Crave Ice

If you find yourself compulsively chewing ice for more than a month, it is crucial to consult a healthcare provider. They will perform blood tests to check for iron deficiency and other potential causes. Self-medicating with iron supplements is not recommended, as excessive iron can be toxic and cause serious health problems. A medical professional can provide a proper diagnosis and recommend the safest, most effective treatment plan.

Conclusion

Chewing ice for anemic people, a condition known as pagophagia, is a coping mechanism rather than a cure. It offers a temporary, perceived boost in alertness but does nothing to solve the underlying iron deficiency that causes the craving. Furthermore, it creates a significant risk of costly and painful dental damage. The most effective and safe course of action is to get a medical diagnosis and treat the iron deficiency with professional guidance. By addressing the root cause and opting for safer alternatives, individuals can protect their dental health and improve their overall well-being. A visit to a doctor or a dental professional is the first step towards breaking this potentially harmful habit.

Frequently Asked Questions

Anemic people often crave ice due to a condition called pagophagia, a form of pica. The leading theory is that the cold sensation from chewing ice increases blood flow to the brain, providing a temporary boost in mental alertness and relieving fatigue caused by low oxygen delivery.

Yes, chewing ice is harmful, especially to dental health. It can cause chipped or cracked teeth, damage enamel, loosen dental work, and cause jaw pain or TMJ disorders. The behavior also does not address the underlying nutritional deficiency.

No, chewing ice does not help with iron deficiency. While it may temporarily alleviate some symptoms like fatigue, it does not correct the low iron levels in the body, as ice contains no nutritional value.

The craving for ice is treated by addressing the underlying iron deficiency. This can involve increasing iron-rich foods in the diet, taking oral iron supplements, or in severe cases, receiving iron infusions under a doctor's supervision.

In many cases, the craving for ice resolves relatively quickly after starting iron replacement therapy, sometimes within a few days to weeks. The speed of resolution depends on the severity of the deficiency and the treatment method.

Yes, while iron deficiency anemia is the most common cause, pagophagia can also be linked to other nutritional deficiencies like calcium, emotional issues such as stress or OCD, and eating disorders like pica.

Safer alternatives include frozen fruit (like grapes or berries), chilled crunchy vegetables (like carrots), sugar-free popsicles, or letting ice melt in your mouth rather than chewing it.
