Iron deficiency can lead to symptoms such as fatigue, pale skin, dizziness, and brittle nails and hair. Iron is a crucial mineral in the production of haemoglobin, a protein that transports oxygen from the lungs throughout the body.

When iron levels drop, conditions like anaemia can occur. A peculiar craving could signal a lack of this nutrient.

Iron deficiency can be triggered by various factors, including absorption issues in individuals with coeliac disease or an iron-poor diet.

While fatigue is one of the most common signs, other symptoms include pale skin, dizziness, headaches, a cold sensation in hands and feet, and fragile hair and nails, according to 20minutos.

An unusual desire to eat ice, known as pagophagia, could be linked to iron deficiency. This condition is part of pica, a disorder that leads to consuming non-food items.

Other forms of pica include geophagia, characterised by eating soil, clay or sand, and amylophagia, associated with starch consumption. Instances have also been reported of people craving substances like coal, chalk, paper, ashes or hair.

The National Library of Medicine states that while pica is more prevalent in children, it can also appear in adults with iron deficiency, even if they haven't developed anaemia.

While munching on ice might not seem immediately harmful, the condition known as pica - which involves ingesting non-food substances - can pose serious health risks. These could range from poisoning to intestinal blockages and digestive system disruptions.

Symptoms of potential poisoning from pica include abdominal pain and bloating, extreme tiredness, nausea, and bouts of diarrhoea. If you find yourself constantly wanting to eat ice or other non-edible items, it's recommended to seek medical advice.

This could be a symptom of iron deficiency, which needs assessment and treatment. Is an insatiable craving and chewing of ice a sign of anaemia?

Does constantly craving and chewing ice indicate anaemia?

Rajiv K. Pruthi, M.B.B.S. responds :"Possibly. The term "pica" describes craving and chewing substances that have no nutritional value - such as ice, clay, soil or paper. Craving and chewing ice, known as pagophagia, is often associated with iron deficiency, with or without anemia, although the reason is unclear.

He said: "Less commonly, other nutritional problems may cause you to crave and chew ice. And in some individuals, pica is a sign of emotional problems, such as stress, obsessive-compulsive disorder or a developmental disorder.

"A thorough medical evaluation can help determine if pica is due to an underlying medical condition. If the cause of pica is an emotional or developmental issue, cognitive behavioural therapy may be helpful."
