Rectal tenesmus

Rectal tenesmus is a medical term used to describe the feeling of incomplete defecation. It is associated with a variety of gastrointestinal disorders, including colorectal cancer, inflammatory bowel disease, and irritable bowel syndrome. The sensation can be very uncomfortable, leading to straining and prolonged time spent on the toilet.

Causes

Rectal tenesmus can be caused by a variety of conditions, including:

• Inflammatory bowel disease: This includes conditions like Crohn's disease and ulcerative colitis, which cause inflammation in the digestive tract.
• Irritable bowel syndrome: This is a common disorder that affects the large intestine and can cause a range of symptoms, including rectal tenesmus.
• Colorectal cancer: This is a type of cancer that starts in the colon or rectum. Rectal tenesmus can be a symptom of this disease.
• Hemorrhoids: These are swollen veins in the lowest part of the rectum and anus, and they can cause rectal tenesmus.
• Rectal prolapse: This is a condition where the rectum, the last part of the large intestine, drops down or slides out of the anus.

Symptoms

The main symptom of rectal tenesmus is a feeling of incomplete defecation. Other symptoms can include:

• Straining during bowel movements
• Abdominal pain or cramping
• A feeling of urgency to have a bowel movement
• Changes in bowel habits, such as constipation or diarrhea

Treatment

Treatment for rectal tenesmus depends on the underlying cause. This can include:

• Medication: For conditions like inflammatory bowel disease or irritable bowel syndrome, medication can help to manage symptoms.
• Surgery: In some cases, such as colorectal cancer or rectal prolapse, surgery may be necessary.
