The disease is a common cause of cold fingers, due to the narrowing of small blood vessels in the fingers - sometimes blood vessels in the toes, ears and nose - due to response to cold weather. or when stressed, stressed. During Raynaud's attack, the body restricted flow to the limbs. This makes the fingers and toes feel cold, numb, and painful and then turn white or bluish purple. When the blood vessels are enlarged and blood flow returns, the fingers are warm, may become red and begin to have a beating again. In most cases, people still do not understand the cause of Raynaud's syndrome. The good news is that this syndrome is mostly annoying, more uncomfortable than harmful to the body. Changing a bit of your routine such as wearing warm, wearing gloves when the weather is cold (even when taking food in the fridge), and limiting stress or strong emotion is often enough to control the well this disease.

2. Autoimmune disease

Sometimes a certain cause that originates from the immune system causes Raynaud's syndrome. Lupus - a disorder in which the immune system attacks the body's own tissues; Scleroderma - a disease that leads to sclerosis and scarring of the skin and connective tissue; Rheumatoid arthritis and several other autoimmune diseases can all lead to Raynaud's syndrome. This is called secondary Raynaud's syndrome. Once the main disease is diagnosed and well controlled, the symptoms of Raynaud's syndrome will improve on its own.

3. Hypothyroidism

Symptoms of cold limbs occur quite common in patients with hypothyroidism. The thyroid gland plays an important role in regulating body temperature. When the thyroid gland is impaired, most organs in the body will slow down and cause symptoms such as fatigue, constipation, weight gain and a cold feeling on the extremities. Hypothyroidism is one of the common diseases in women and people over 50 years old.

4. Circulatory system problems

Poor blood circulation to the limbs occurs when oxygen-rich blood flow and nutrients decrease circulation in the body, including a decrease in the heart's ability to pump blood (heart failure), embolism (atherosclerosis in arteries). large and small blood vessels) or other causes. When the heart is unable to pump enough blood to all of the body's organs, you will feel cold and numb in the limbs - these are also located furthest away from the heart.

5. Anemia

Anemia is a condition where the body cannot produce enough red blood cells or the amount of hemoglobin in the blood is too low. Anemia causes the lack of oxygen to supply the organs in the body and is also the reason for cold hands. Some of the most common causes of anemia include not getting enough iron in your diet, blood loss (due to heavy bleeding during your period, ulcers, gastrointestinal bleeding), certain cancers. Letters and digestive disorders (Celiac disease, Crohn's disease). In addition to symptoms of cold hands, anemia also causes fatigue, headache, dizziness, shortness of breath and pale skin. In most cases, iron deficiency anemia and its symptoms can be cured by iron supplementation.

6. Vitamin B12 deficiency

Vitamin B12, rich in red meats, poultry, eggs, milk and dairy products, plays a very important role in the formation of red blood cells. A deficiency of this vitamin can lead to a decrease in the production of red blood cells (and consequently anemia). Vitamin B12 deficiency is quite common among vegetarians, and people over 50 may impair their ability to absorb this vitamin from food. People with some digestive disorders like Crohn's disease or Celiac disease are also at risk of B12 deficiency. A simple blood test can help find out if vitamin B12 deficiency is the cause of limb chills. If that's the main reason, taking a B12 supplement can help resolve symptoms within weeks to a month.

7. Lowering blood pressure

Hypotension or low blood pressure can have a variety of causes, including dehydration, blood loss, use of certain medications, and hormonal disorders. When blood pressure is lowered, blood vessels will shift from the limbs and give priority to perfusion to vital organs in the body, which makes the hands and feet become cold. If you have symptoms of low blood pressure such as dizziness, blurred vision, tiredness, nausea, muscle weakness and confusion, see your doctor right away.

8. Stress and anxiety

Stress can have a lot of effects on your body, and your hands are no exception. When you experience prolonged stress and anxiety, your body goes into a "fight or run away" stage. Increased adrenalin levels cause constricting of the limb vessels leading to cold hands and toes (as well as the feet and toes). Therefore, having good stress management can help alleviate your symptoms.

Typical examples are beta blockers (antihypertensives), some cancer drugs, migraine medications and over-the-counter decongestants. Consult your doctor or pharmacist to find out if the medications you are taking can cause cold symptoms of the extremities.
