The following causes are considered for colds and bloody noses. First, due to dry air, the nasal mucosa is dry and fragile, and the patient blows his nose, causing bleeding. Secondly, the patient’s symptoms of runny nose are obviously serious and repeatedly blowing the nose, which causes local damage, and the symptoms of nasal blood also appear. The third aspect is whether the patient has abnormal coagulation mechanism, such as whether he has leukemia, aplastic anemia, coagulation dysfunction and these problems. It is recommended that the patient visit the hospital to check the coagulation index and also the blood routine to exclude serious organic lesions. After ruling out these diseases, consider that cold and nasal discharge with blood are caused by simple cold, and symptomatic hemostatic treatment can be carried out, such as local pressure to stop bleeding. You can take oral mild hemostatic drugs, such as Panax notoginseng powder or Yunnan Baiyao capsules for symptomatic treatment.
