Cold feet and hands: is circulation the cause?

Healthy blood vessels adjust their width as temperature changes. A circulation problem becomes more concerning when coldness is persistent, stronger on one side, associated with pale or blue skin, or accompanied by pain during walking, numbness, weakness, or sores. Peripheral arterial disease affects arteries supplying the limbs and can reduce oxygen delivery to tissues. Anaemia changes how much oxygen blood carries, while hypothyroidism can slow body processes and increase sensitivity to cold. The sensation alone cannot distinguish these conditions.

Compare both hands and feet in a comfortably warm room, without rubbing hard or applying intense heat. Notice whether colour and temperature return after gentle movement, and whether symptoms occur with walking or at rest. Keep skin moisturised, protect it from cuts, and choose footwear that does not press on toes. Arrange a clinical review if symptoms continue; the clinician may check pulses, skin, sensation, and blood tests. Avoid self-treating with iron unless deficiency has been established.

Seek urgent assessment for a limb that suddenly becomes cold, pale or blue, especially with severe pain, weakness, or loss of sensation. A new wound, blackening skin, or pain at rest also needs prompt medical attention. For gradual symptoms, arrange a review when walking pain, repeated colour changes, or numbness are developing.

Could my pattern suggest reduced arterial flow? Will you check pulses and sensation? Do I need tests for anaemia, iron deficiency, or thyroid function? How should I care for my feet while this is being assessed?
