Due to the rupture of blood vessels during a nosebleed, the coagulation factors in the body rapidly agglutinate to achieve the effect of hemostasis, which can cause the appearance of clots, indicating that the coagulation function is normal. The clot will come off by itself when it dries up and wrinkles, and generally does not need special treatment. However, nosebleed itself is not a normal phenomenon, may be due to environmental dryness and other physiological factors, but also due to trauma, nasal diseases and other pathological factors cause. If the bleeding is large and cannot be stopped, it is recommended to go to the hospital in time, do the relevant examination, clarify the cause of the disease, and then follow the doctor’s instructions for treatment to avoid delaying the condition. In daily life, you should avoid blowing your nose hard, digging your nose with sharp objects, and try not to pick your nose.
