Stinging, burning anal pain, blood-streaked stool, and tenesmus are typical symptoms that emerge when inflammation develops in the rectum. Proctitis refers to inflammation of the rectal mucosa, and modern medicine recognizes a wide variety of causes for it.
One of the most common causes is inflammatory bowel disease, which may remain confined entirely to the rectal region as a localized presentation of ulcerative colitis or Crohn's disease. In these cases, an abnormal immune response causes the body to attack its own bowel. In addition, acute proctitis resulting from bacterial, viral, or parasitic infection is common. Radiation proctitis arising as a complication of radiotherapy, certain medications, food allergies, and sexually transmitted infections can also serve as causes.
Symptoms primarily include rectal pain, discomfort during defecation, tenesmus, frequent diarrhea, mucus discharge, and hemorrhage. Chronic inflammation of this nature weakens the protective intestinal barrier of the rectal mucosa, facilitating conditions such as leaky gut syndrome. It also disrupts the gut microbiota, which can trigger a systemic inflammatory response. Beyond localized anal pain, this process influences the gut-brain axis, worsening stress and anxiety while altering overall immune function.
The damp-heat concept in Donguibogam closely aligns with modern understandings of inflammatory cascades, dysbiosis, and increased mucosal permeability. Similarly, liver qi stagnation reflects the physiological impact of stress on the autonomic nervous system and intestinal motility. Proctitis is therefore best understood not as an isolated anal disorder, but as a systemic sign involving the immune system, nervous system, and endocrine system. If these symptoms persist, consulting a medical professional for an accurate diagnosis and appropriate care is essential.
