When we think of iron deficiency, the first symptoms that come to mind are usually fatigue, pale skin, or frequent cold hands and feet. But did you know that numbness or tingling in your hands and feet could also be a warning sign? While it might seem like a symptom of a nerve issue or poor circulation, experts say that iron deficiency anaemia can sometimes present with unusual neurological signs, including numbness.

How Iron Deficiency Affects the Nervous System

Iron is a vital mineral that plays an essential role in transporting oxygen throughout the body. When you don't have enough iron, your red blood cells can’t carry sufficient oxygen to your tissues — and that includes your brain and nerves. According to the National Institutes of Health (NIH), iron deficiency anaemia can result in neurological symptoms like numbness, tingling, and even dizziness or difficulty concentrating.
This happens because a lack of iron reduces oxygen supply to peripheral nerves. In some cases, people may start experiencing pins-and-needles sensations or mild numbness, particularly in the extremities like fingers or toes. It’s not the most common sign, but it should never be ignored.
Over time, if iron levels remain low, these symptoms can worsen. In severe cases, iron deficiency may also lead to restless leg syndrome, a condition linked to nerve dysfunction and often misdiagnosed.

Who’s at Risk?

Iron deficiency is more common than many people think. The World Health Organization (WHO) states that over 30 per cent of the global population is anaemic, and the most common cause is iron deficiency. Those particularly at risk include:
    Women with heavy menstrual bleeding
  • Pregnant women
  • Children and adolescents in growth spurts
  • People with chronic illnesses (like kidney disease or inflammatory bowel disease)
  • Vegetarians or vegans who may lack dietary iron
  • What You Can Do to Boost Iron Levels

    If you're experiencing unexplained numbness or tingling, it’s important to consult a doctor and ask for a complete blood count (CBC) test and serum ferritin level test to evaluate your iron status.
    Here’s how you can support your body’s iron levels naturally and through medical advice:

    1. Eat Iron-Rich Foods

    There are two types of iron:
      Heme iron, found in red meat, poultry, and fish, is more easily absorbed by the body.
  • Non-heme iron is found in plant sources like lentils, beans, tofu, spinach, and fortified cereals.
  • Pairing non-heme iron with vitamin C-rich foods like oranges, tomatoes, or bell peppers can improve absorption.

    2. Avoid Iron Blockers During Meals

    Tannins (in tea and coffee), calcium supplements, and high-fibre foods can hinder iron absorption. Try to consume these at a different time than your iron-rich meals.

    3. Consider Supplements—But Only If Prescribed

    Iron supplements can be effective, but self-medicating is not advised. Too much iron can be harmful, especially for people with certain health conditions.
    Numbness or tingling may not always be due to poor posture or nerve compression — it could be your body’s subtle cry for iron. If you’re noticing unusual symptoms and feel persistently tired or weak, it’s time to get your iron levels checked. With the right dietary choices and medical support, iron deficiency is both preventable and treatable.
