Q. What causes rectal tenesmus?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Rectal tenesmus can be caused by a variety of underlying medical conditions and factors. Some common causes and contributing factors include:
1. Inflammatory bowel disease (IBD): Conditions like Crohn's disease and ulcerative colitis can lead to rectal tenesmus due to inflammation and irritation of the rectum and colon.
2. Irritable bowel syndrome (IBS): IBS can cause discomfort and changes in bowel habits, leading to rectal tenesmus as a symptom.
3. Hemorrhoids: Swollen blood vessels in the rectum or anus can cause rectal pressure and discomfort, leading to tenesmus.
4. Constipation: Severe or chronic constipation can result in a sensation of incomplete bowel movements and rectal tenesmus.
5. Gastrointestinal infections: Infections such as gastroenteritis can irritate the rectum and lead to the feeling of needing to defecate even when the bowels are empty.
6. Colorectal cancer: Rectal tenesmus can be a symptom of colorectal cancer, especially if it is associated with other concerning signs, such as blood in the stool.
7. Anal fissures: Small tears or fissures in the lining of the anus can cause pain and the sensation of needing to have a bowel movement.
8. Pelvic floor disorders: Dysfunction in the pelvic floor muscles can lead to difficulties with bowel movements and rectal tenesmus.
9. Prostatitis: Inflammation of the prostate gland in men can sometimes cause rectal discomfort and tenesmus.
10. Psychological factors: Stress, anxiety, or emotional distress can exacerbate or contribute to rectal tenesmus in some individuals.
It's important to note that rectal tenesmus is a symptom and not a diagnosis in itself. If you experience rectal tenesmus, it's crucial to consult a healthcare professional for a thorough evaluation and appropriate diagnostic tests to determine the underlying cause. Treatment and management will depend on the specific condition or factors contributing to the tenesmus.
