皮膚紅腫 Erythema

肌膚紅腫是一種皮膚不正常的微血管鬱結的泛紅現象,常見的主要特徵是特定部位出現發炎現象。發炎造成微細血管局部擴張,導致肌膚發紅。
Erythema is an abnormal redness of the skin caused by congestion of the capillaries and is one of the major signs that inflammation is present at a particular location of the skin.  This causes the capillaries to dilate (enlarge) which then results in the redness of the skin.

以下情形均可造成肌膚紅腫:
 Erythema can be caused by various factors such as:
  • 感染 infection
  • 日晒傷 sunburn
  • 電療或電燒 electrical treatments or burns
  • 接觸性過敏 contact allergies
  • 燒傷 burns
  • 系統性過敏 systemic allergies
  • 中毒 toxicity
  • 運動 exercise
  • 蚊蟲叮咬 insect stings
  • 過敏 allergies
  • 細菌感染 bacterial infection
  • 病毒感染 viral infection
  • 黴菌感染 fungal infection
  • protozoa infection
  • 按摩 massage
  • 風吹傷 windburn etc.  

雖然肌膚紅腫不一定是嚴重的健康問題,但是卻可能隱含健康問題的徵兆。
 Although erythema need not be a serious medical condition, it may be an underlying symptom of a medical condition. Should you be concerned regarding any unusual symptoms, please contact your medical practitioner.
