A short blog on what is Reynauds phenomenon .
Raynaud’s phenomenon is a vascular condition characterized by pale to blue coloured numb digits due to lack of oxygen. The Raynaud’s phenomenon is usually seen to effects the body extremities such as fingers, toes, nose etc. The main reason behind this syndrome is unknown but abnormal nerve control of blood-vessel diameter and nerve sensitivity to cold are suspected of being involved. The symptoms depend on the frequency, severity and duration of the blood vessel spasm.
There is no current diagnostic method to know whether a person has Raynaud’s phenomenon or not. The treatment is preventing one from being exposed to extreme hot or cold temperatures and avoid stress, strain and smoking.
SYMPTOMS OF REYNAUD’S DISEASE
Symptoms include series of skin discolouration of the fingers and toes when exposed to hot or cold temperatures. Skin discoloration happens due to abnormal spasm of blood vessel which causes lesser flow of blood to local tissues. Diminished blood flow results in lesser amount of oxygen being available for the tissues. Initially this causes the digits to turn white , But gradually lower oxygen level causes the fingers to turn blue (cyanosis). Finally , when the blood vessels open it causes the digits t turn red and may also lead to swelling.
The Reynaud’s phenomenon is mostly seen to affect women. Also one can have Reynaud’s phenomenon alone or due to rheumatoid arthritic conditions.
TYPES OF REYNAUD’S
- In case a person suffers from Reynaud’s alone, the is is known as Reynaud’s disease or primary Reynaud’s disease.
- And , if Reynaud symptoms occur in association or due to conditions such as lupus or rheumatoid arthiritis , it is known as secondary Reynaud’s disease.
IS REYNAUD’S LETHAL?
Reynaud’ is not a lethal condition. Although the severity of it depends on several conditions. Severe cases such as completely blocked blood artery can lead to skin sores (ulcers) or dead tissue (gangrene). It’s rare, but if this happens, the doctor might have to remove a finger or toe.
