From the Guidelines
Yes, iron deficiency can cause feelings of coldness, as it reduces the body's ability to produce hemoglobin, leading to decreased oxygen delivery to tissues and organs, and subsequently, cold intolerance. This is a common symptom of iron deficiency anemia, alongside fatigue, weakness, pale skin, and shortness of breath 1. Iron deficiency anemia can be diagnosed by blood testing and remedied by iron replacement therapy (IRT) using the oral or intravenous route, as stated in the British Society of Gastroenterology guidelines for the management of iron deficiency anaemia in adults 1.
Key points to consider:
- Iron deficiency anemia can result from poor dietary intake, malabsorption of dietary iron, and chronic blood loss, among other causes 1
- Approximately a third of men and postmenopausal women presenting with IDA have an underlying pathological abnormality, most commonly in the GI tract 1
- Treatment typically involves iron supplements, and dietary changes to include iron-rich foods can help maintain healthy iron levels long-term
- Cold intolerance is a symptom that can be addressed by replenishing iron stores, usually through iron supplements like ferrous sulfate, taken 1-3 times daily, for 3-6 months 1
It is essential to get iron levels checked if experiencing persistent coldness, especially with other symptoms, to determine the underlying cause and appropriate treatment. With proper management, iron deficiency anemia can be effectively treated, and symptoms like cold intolerance can be alleviated 1.
