When to worry about cold intolerance with anaemia

Anaemia can reduce oxygen delivery to tissues, leaving you feeling cold even when other people are comfortable. It may occur with tiredness, pale skin, headaches, reduced concentration, dizziness, or shortness of breath. Cold intolerance can also come from thyroid problems, low body weight, medicines, or the environment. The symptom cannot establish the type or cause of anaemia on its own.

Arrange a clinical review if feeling cold is new, lasts despite treatment, or is limiting work, sleep, or usual activities. Keep a note of fatigue, breathlessness, paleness, headaches, bleeding, dietary changes, and menstrual patterns. Follow the treatment prescribed for your anaemia and avoid starting supplements without advice, as treatment depends on the underlying cause and blood results.

Get emergency help for chest pain, severe breathlessness, fainting, confusion, collapse, or a fast heartbeat with marked weakness. Seek urgent assessment for heavy bleeding, black or bloody stools, or rapidly worsening symptoms. These warning signs need prompt evaluation rather than observation at home.

Ask which type of anaemia you have, what may be causing it, and when your blood tests should be repeated. Discuss whether bleeding, diet, absorption, pregnancy, or another illness needs assessment. Ask what level of breathlessness, dizziness, or fatigue should prompt urgent contact.
