Anal swelling stomach grumbling may be caused by acute gastroenteritis, ulcerative colitis, rectal cancer, pelvic diseases and other reasons.
1. Acute gastroenteritis: bacteria, viruses and other pathogens infect the gastrointestinal tract, resulting in acute inflammatory lesions of the gastrointestinal mucosa, increased exudation of intestinal mucosa, congestion and edema, increased water in the intestinal lumen, and diarrhea, gurgling, and inflammation involving the rectum and anus, anal distention occurs.
2. Ulcerative colitis: intestinal immune disorder leads to chronic non-specific inflammatory changes in the colorectal mucosa, extensive ulceration, bleeding and erosion of the intestinal mucosa and other lesions, resulting in diarrhea, urgency and heaviness (discomfort in the lower abdomen, wanting to defecate very much, and feeling of incomplete defecation after defecation), and anal swelling and distension, and so on.
3. Rectal cancer: malignant proliferation of rectal tissues leads to normal intestinal dysfunction, and ulceration and bleeding of cancerous tissues stimulate intestinal mucosa, resulting in anal swelling and distension, which leads to the above symptoms.
4. Pelvic diseases: Pelvic diseases such as pelvic inflammatory disease and ectopic pregnancy can easily involve the neighboring rectum and repeatedly stimulate the rectal wall, resulting in the above symptoms.
Anal distension and stomach grumbling may be related to a variety of factors, it is recommended to consult a doctor as soon as possible to clarify the diagnosis.
