How common is cold intolerance in iron deficiency anaemia?

Iron helps your body make haemoglobin, the part of red blood cells that carries oxygen. When iron stores are low, reduced oxygen delivery may leave you feeling unusually cold, especially in your hands and feet. Tiredness, reduced stamina, dizziness, pale skin, headaches, or breathlessness can occur alongside this symptom. Cold intolerance alone cannot identify the cause, and it does not show whether iron deficiency is present.

Arrange a medical assessment if the symptom is persistent, worsening, or accompanied by fatigue. A clinician may ask about diet, menstrual or other blood loss, digestive symptoms, and medicines, then choose blood tests to check haemoglobin and iron status. Do not start high-dose iron without advice; the right treatment depends on confirming deficiency and finding why it developed. Keep warm while awaiting assessment and record other symptoms and their timing.

Seek urgent help for severe breathlessness, fainting, chest discomfort, confusion, or marked weakness. Arrange prompt care for black or bloody stools, heavy unexpected bleeding, or rapidly worsening symptoms, because these may need assessment beyond a routine appointment.

Could iron deficiency explain my cold intolerance and other symptoms? Which blood tests are appropriate? Could blood loss, diet, absorption, or another condition be contributing? If iron treatment is advised, how should I take it and when should it be reviewed?
