Congestion and edema of the luminal mucosa may be caused by trauma, bacterial infection, or allergic reaction, and therefore requires treatment or medication to address the specific cause. 1. Trauma: When the local luminal mucosa is compressed by external force or after local traumatic injury, it may stimulate the submucosa to become congested and edematous. For the secondary mucosal injury caused by trauma, we need to carry out trauma treatment such as suture or debridement for the trauma site, which can effectively relieve the phenomenon of mucosal edema. 2. Bacterial infection: when there is local bacterial infection on the mucosal surface, it will also stimulate the luminal mucosa to become congested and edematous, which can be effectively relieved by applying antibacterial ointment on the mucosal surface or taking antibacterial drugs orally to alleviate the edematous and congested effect. Commonly used antibacterial drugs include roxithromycin capsules. 3. Allergy: when the body has an allergic reaction or the mucosal surface is in direct contact with allergens, it will also lead to the immune system to appear immune stress, which triggers the phenomenon of congestion and edema of the mucous membrane, at this time, you can use chlorpheniramine maleate tablets, cetirizine and other anti-allergic drugs to effectively alleviate the allergic reaction. When the phenomenon of congestion and edema occurs in the luminal mucosa, the specific cause of the disease should be clarified and appropriate drugs should be selected under the guidance of the doctor.
