If we go outside in the winter without gloves, after returning home it will be easy to see our fingers turn white. This is just a very normal reaction of the body when it is cold and then our hands will return to normal when heated. However, for many people this is a warning phenomenon of a very serious disease in the winter, which is Raynaud's disease.
This disease affects the blood supply lines for each part of the body.
Raynaud's disease is a common syndrome that affects the blood supply lines for each part of the body, especially the fingers and toes. This disease usually occurs when the weather is cold or due to patients suffering from anxiety, prolonged stress.
When the temperature drops, blood vessels enter the muscle to temporarily contract, clogging blood flow. The affected areas may turn white, blue and eventually red when the blood is returned to circulation.
There are two main types of Raynaud's: primary (Raynaud's disease) and secondary (Raynaud's syndrome).
People with Raynaud's disease are more likely to have vascular constrictions.
Raynaud's disease usually does not have a specific cause, it only appears when the blood vessels near your skin contract in the cold. People with Raynaud's disease are more likely to have vascular constrictions. However, compared to Raynaud's syndrome, it is still milder and more common, does not need to be treated too time-consuming.
On the other hand, secondary Raynaud's syndrome occurs in the body through skin sores or some internal health problem. For this type of Raynaud, you need to take medicine or conduct surgery to treat thoroughly.
People with Raynaud's disease often experience symptoms that come from fingers and toes, but it can also affect other body parts like the nose, ears, lips and nipples. Due to deep cold temperatures or emotional changes, arteries will constrict or cut off the blood supply to certain areas, resulting in the following symptoms:
