Female lower abdominal pain and anal swelling

Sometimes female friends will experience lower abdominal distension and pain. If it is not that serious, there is no need for too systematic treatment and processing. Only occasional anal swelling may occur. However, if there is an inflammatory problem, corresponding treatment should be taken. Do not take it lightly at this time, otherwise your condition will worsen and eventually become out of control.

1. Prolapsed anal disease

(1) Prolapsed internal hemorrhoids, prolapsed rectal mucosa, and polyps can all stimulate the dentate line area (a highly specialized sensory nerve terminal tissue band that is the inducing area for defecation movements), causing a feeling of heaviness and distension in the anus and thus a feeling of defecation.

(2) Uterine prolapse and vaginal prolapse often cause a feeling of falling. In patients with internal rectal prolapse, the mucosa sinks into the anal canal, stimulating the nerve endings in the dentate line and producing a feeling of heaviness.

2. Inflammatory diseases

(1) Colitis, proctitis, anal cryptitis, and anal papillitis can all cause anal swelling due to inflammation irritating the dentate area.

(2) Submucosal rectal abscesses and pelvic rectal space abscesses are caused by inflammation that stimulates the pelvic nerves and often result in swelling in the anus and rectum.

(3) Acute bacterial prostatitis may cause swelling in the perineum.

(4) Foreign bodies in the anorectal canal can cause bleeding and ulceration of the rectal mucosa, difficult defecation, and anal swelling.

3. Compressive diseases

(1) The contents of pelvic floor hernia compress the rectum and anal canal, which may cause anal swelling. The innervation of the rectum and surrounding organs mainly comes from the pelvic plexus. Once the sacral nerves, which are components of the pelvic plexus, are compressed by lumbar disc herniation, the patient may experience discomfort and heaviness in the anus.

(2) Retroverted uterus can cause anal swelling. If blood accumulates in the rectouterine pouch, anal swelling may occur.

(3) In the late stage of cervical cancer, compression of the rectum may also cause anal swelling.

4. Surgical stimulation

The anal swelling that occurs after anorectal surgery may be related to the stimulation of the defecation receptors by the surgery and inflammation. If swelling occurs 1-2 days after internal hemorrhoid injection, it is because the hemorrhoids become temporarily larger due to the injection of the drug solution. When the ligature of the internal hemorrhoids is not yet removed during mixed hemorrhoid surgery, it can stimulate the anal canal to produce a urge to defecate, causing swelling in the anal canal.

In high anal fistula incision and thread hanging surgery, in the early stage of rubber band falling off, the anus often falls down due to the severance of part of the anal muscles. After receiving negative pressure suction ligation treatment for hemorrhoids, all patients felt unbearable swelling and heaviness in the anus. After surgery for complex anal fistula, large scars may cause anal swelling and discomfort. The main reason for the feeling of anal distension after stapled hemorrhoidectomy (PPH) is that the operating plane is too low, and it may also be related to anastomotic inflammation and rectal traction reflex.
