The Federal Center for Health Education explained that blue spots on the body have several causes, some of which are simple, while others are serious. The German center indicated that simple causes of blue spots on the body include impacts, taking blood-thinning medications such as those containing acetylsalicylic acid, and psychological stress.
On the other hand, serious causes of blue spots on the body include bacterial or viral infections, vitamin K deficiency, blood clotting disorders such as hemophilia, and hypothyroidism or hyperthyroidism. In the worst cases, blue spots on the body may indicate leukemia (blood cancer).
Therefore, it is important to consult a doctor if blue spots persist for a long time, especially if accompanied by other symptoms such as unexplained pain, nausea, fever, and swelling (especially in the head and joints).
