Cold feet may be a signal of thyroid issues. This gland plays a crucial role in regulating metabolic functions in our bodies, and one possible reason for persistently cold feet could be its dysfunction, known as hypothyroidism.
Warning sign: If your feet are always cold, it's time to see a doctor. Here's why it matters for your health.
If your feet are cold due to the frost, it's a normal response of the body to environmental conditions. However, if you consistently feel cold in your feet even when you're in warm spaces, it may indicate serious health issues. Here, we discuss what those issues might be.

Cold feet can be caused by more than just chilly weather.
Avoid self-diagnosis! In our articles, we compile the latest scientific research and opinions from reputable health experts. However, remember: only a doctor can provide a diagnosis and prescribe treatment.Hypothyroidism
“Individuals with reduced thyroid activity may experience fatigue, weight gain, and intolerance to cold temperatures, which ultimately leads to cold feet. Fortunately, thyroid conditions can be diagnosed with a simple blood test,” explains Dr. Kelly Johnson-Arbo.

Although this condition is quite common, it can easily go unnoticed for long periods, as people often overlook simple symptoms like cold feet. Diabetics have a heightened risk of developing peripheral artery disease, which reduces or, less frequently, completely blocks blood flow to the limbs.
However, coldness is not the only indicator of this issue:
- In diabetes, feet may take on a purplish-blue hue or appear pale;
- when pressure is applied to the outer part of the foot, the area may remain pale longer than usual;
- the pulse in the foot may be hard or impossible to detect.
Anemia
This condition is caused by a deficiency of iron or vitamin B-12, leading to impaired blood flow. Moreover, individuals with anemia often experience fatigue, pale skin, and an increased heart rate. Anemia patients typically show low levels of hemoglobin and red blood cells in circulation, along with disrupted oxygen transport throughout the body and the development of hypoxia.
Lung Diseases
Cold feet may indicate three lung-related issues: chronic obstructive pulmonary disease (COPD), pulmonary hypertension, and pulmonary embolism.

Pulmonary hypertension is a condition where blood vessels in the lungs narrow, making it hard for blood to pass through. As a result, the body may not receive enough oxygen, which can also cause poor circulation and cold limbs.
It’s important to note that COPD and pulmonary hypertension are often accompanied by additional symptoms: shortness of breath, wheezing, fatigue, and chest pain or tightness.
Pulmonary embolism is a serious condition in which a blood clot forms in the lungs, blocking blood flow.
Ciguatera Poisoning
This illness occurs after consuming certain types of reef fish that contain a specific biological toxin—ciguatoxin—in their tissues. These toxins do not diminish during cooking, making it nearly impossible to determine whether the fish is contaminated before and after eating. Symptoms of poisoning include nausea, abdominal pain, and cold feet.
If your feet are regularly cold, take the time to consult a doctor!
