cold hands and feet all the time
Persistent cold hands and feet is a common symptom often related to benign circulatory variations, but it can sometimes indicate underlying vascular, endocrine, or autoimmune conditions.
Possible causes
- 01
Primary Raynaud's phenomenon
commonAn exaggerated vascular response to cold temperatures or stress, causing temporary spasm of small blood vessels in the extremities.
Evidence
- NHS: Raynaud's, 2023
- 02
Hypothyroidism
possibleAn underactive thyroid gland slows the body's metabolic rate, reducing heat production and causing cold sensitivity.
Evidence
- NICE CKS: Hypothyroidism, 2023
- 03
Iron-deficiency anaemia
possibleLow iron levels reduce the blood's oxygen-carrying capacity, which can impair peripheral circulation and temperature regulation.
Evidence
- Mayo Clinic: Iron deficiency anemia, 2023
Recommended tests
Thyroid function panel
→TSH, Free T3, Free T4 — first-line test for fatigue, weight change, hair loss, mood.
Why: To check for hypothyroidism, a common and treatable cause of cold intolerance.
Guideline
- NICE CKS: Hypothyroidism - Scenario: Suspected hypothyroidism, 2023
Iron & ferritin
→Ferritin, serum iron, TIBC — checks for iron-deficiency anaemia.
Why: To rule out iron-deficiency anaemia, which can impair oxygen delivery and thermoregulation.
GP consultation
→30–60 minute consultation with a British-trained GP — clinic, home or video.
Why: A comprehensive clinical evaluation to assess peripheral pulses and rule out secondary connective tissue disorders.
Guideline
- NICE CKS: Raynaud's phenomenon - Assessment, 2021
When to worry
- Skin color changes in the fingers or toes that turn white, blue, and then red, accompanied by pain or numbness.
- Non-healing sores, ulcers, or skin infections on the fingers, toes, or feet.
- New joint pain, muscle weakness, skin thickening, or difficulty swallowing.
- Cold extremities accompanied by unexplained weight gain, severe fatigue, or hair loss.

"Called at 8am with a fever, had a British-trained doctor at my door by 11. He sat with me for 45 minutes — not the 5 minutes I'm used to. Prescription delivered same day. Felt like having a proper GP again."
"We finally have one doctor who knows all of us. The kids actually like going. Follow-up calls happen without us chasing. Worth every dirham."
"The 40+ marker report came back with a real conversation, not a PDF dumped in my inbox. Caught a vitamin deficiency I'd been ignoring for years."
"After surgery I dreaded going back to a hospital for dressings. Their nurse came every other day, the doctor checked in by WhatsApp. Healed faster than I expected."
"Fell ill on day two of our trip. Doctor in the suite within 90 minutes, full assessment, prescription to the hotel pharmacy. Genuinely NHS-standard care in Dubai."
"My father refuses to leave the house. Aafiyah's team comes monthly, manages his medication, and treats him with such dignity. It changed everything for our family."
