Hi, a friend of mine told me that he has some kind of medical problem. Apparently some time ago he started having some kind of attacks directed to his fingers. He can not stay outside for long if it is too cold. The doctor told him that he has blood vessels problems and was diagnosed with raynauds. What is the connection between these two?

Hi, Raynaud's disease is a condition that affects small blood vessels that are located in the skin. This is the connection between these two. The blood vessels I am talking about are usually the ones placed in fingers and toes. When exposed to cold or stressful situations, our blood vessels are being narrowed by our body. This is happening so that the core temperature of the body would be preserved. When a person has Raynaud's, the narrowing is exaggerated. This causes the affected parts of the body to remain with no or very small amounts of blood. As a result, they become numb and change color. The best thing for your friend is to listen to his doctor and maintain the prescribed therapy.
