​After a few days of menstruation, there is bleeding again

If your period stops for a few days, it may be due to irregular menstruation. The normal menstrual cycle of women is very regular, with most cycles lasting about 28 to 30 days. Illness may be caused by gynecological problems or emotions. If there is bleeding again after the menstruation has stopped for a few days, the guidance is: it is recommended to use some Chinese medicine, such as Dingkundan, for menstruation, pay attention to rest, and observe the next menstrual situation. If not, you need to go to the hospital for treatment.

1. Damage to the vessel wall is common in hypoxia, which causes degeneration of capillary endothelial cells; sepsis (especially meningococcal sepsis), rickettsial infection, hemorrhagic fever, snake venom, organophosphorus poisoning, etc. cause damage to the capillary wall; some drugs can cause allergic vasculitis; vitamin C deficiency can cause rupture of the capillary basement membrane, decrease in pericapillary collagen, and separation of endothelial cell junctions, resulting in increased permeability of the vessel wall; in Henoch-Schönlein purpura, allergic vasculitis is caused by the deposition of immune complexes on the vessel wall.

2. Thrombocytopenia and dysfunction The normal number and quality of platelets are important factors in maintaining normal capillary permeability. When the number of platelets decreases to a certain level, exudative bleeding may occur. For example, aplastic anemia, leukemia, and extensive tumor metastasis in the bone marrow can reduce platelet production; idiopathic thrombocytopenic purpura, thrombotic thrombocytopenic purpura, and DIC cause excessive platelet destruction or consumption; certain drugs induce an immune response to antigen-antibody complexes in the body, and the immune complexes formed are adsorbed on the surface of platelets, causing the latter to be phagocytosed by macrophages along with the immune complexes; some bacterial endotoxins and exotoxins also have the effect of destroying platelets.

Structural and functional defects of platelets can also cause exudative bleeding. Many of these diseases are congenital, such as thrombasthenia (lack of fibrin receptors on the platelet cell membrane) and storage pool disease (lack of one or more granules, resulting in insufficient ADP reserves; it can also occur due to acquired damage to bone marrow megakaryocytes), in which the platelet adhesion ability is defective; in Bernard-Soulier syndrome (lack of von Willebrand factor receptors on the platelet cell membrane), platelets cannot adhere to collagen fibers, which can lead to coagulation disorders or bleeding tendencies.
