According to an epidemiological survey, about 3-5% of the population will have a "Raynaud's phenomenon". Typical Raynaud's phenomena occur in cold condition (such as cold currents, entering air-conditioned rooms, and taking things from the refrigerator) or emotional excitement and increased stress When the finger or toe arteries contract and spasm, the color of the extremities appears pale, or changes from pale to purple, usually lasting 15-20 minutes. When the blood vessels recirculate and congestion, flushing will appear. Generally, the upper limbs are more serious. Symptoms of the middle or ring finger first appear, and then spread symmetrically to other fingers. Occasionally, it can also occur in the lower limbs, ears, nose, tongue, and nipples, and even affect internal organs.
As Raynaud's symptoms are mainly caused by vasoconstriction and spasm, all relevant symptoms will be relieved as long as the temperature is warmed, especially in subtropical regions such as Taiwan and Hong Kong. Due to the cold temperature will not be too long, patients with Raynaud's Symptoms are ignored because of rising temperatures and remission of symptoms. The appearance of "Raynaud's Symptoms" is actually a warning message from the body, reminding us to make good lifestyle adjustments.
Clinically, Raynaud's phenomenon is divided into primary and secondary; primary Raynaud's phenomenon usually does not find a potential cause, also known as primary Raynaud's syndrome or Raynaud's disease ), The prognosis is good, 15 to 30-year-old female is the target of hair. Secondary Raynaud's phenomenon has a poor prognosis, and severe cases can even cause complication of fingertip ulcers or gangrene, usually accompanied by other diseases, including:
The human body caused by secondary Raynaud's disease, in addition to causing discoloration of the fingers and toes, can cause the skin of the fingers and toes to fester or harden in severe cases due to insufficient blood supply. There are some potential causes, which are more likely to cause severe constriction and obstruction of larger blood vessels, which can lead to skeletal necrosis or increased pulmonary artery pressure. Hip pain, constant movement, and even breathing difficulties can be life-threatening. Therefore, when Raynaud's phenomenon occurs, you should seek medical treatment as soon as possible.
Raynaud's syndrome and anemia are not closely related, mainly due to vasoconstriction and spasm. Some traditional Chinese medicine prescriptions that promote blood circulation, such as cinnamon sticks, ginger, etc., may be helpful for clinical symptoms. In order to achieve safe and effective improvement results, primary Raynaud's disease is not strictly a disease, but a clinical phenomenon. Through this clinical phenomenon, it is implied that patients need special maintenance, unless the symptoms after special maintenance, Deterioration is still needed before treatment with prescription drugs is needed.
The principles and methods of general prevention include:
If the patient is negligent, unmaintained and untreated, in the severe winter, the last hypoxic tissue will cause necrosis, ulcers, and even ulceration and inflammation, and some nearby tissues, such as bones, skin, etc., may be necrotic due to hypoxia, causing severe bone soreness, and even serious consequences such as being unable to walk.
