What are the most common causes of pain in the large intestine?

Large intestine pain is often caused by an intestinal obstruction, intestinal polyps, or Crohn's disease. Each of these affects different parts of the large intestine, but the pain is often localized to the abdominal area. The different symptoms that accompany each of these diseases and conditions can help distinguish which one an individual is suffering from. All of these causes require medical attention due to the risk of cancer and other serious diseases. Treatments often range from medication to minor surgery, and there are natural remedies to help relieve symptoms.

Intestinal obstruction is a common cause of pain in the large intestine. Some of the symptoms include abdominal pain, constipation, and sometimes rectal bleeding. The three main causes of intestinal obstruction are colorectal cancer, volvulus, and diverticular disease. The volvulus is the torsion of the intestine, which forms a closed circuit. Diverticular disease occurs when the pouches, called diverticula, that surround the large intestine constrict it and make the passageway inside too narrow.

Another common cause of pain in the large intestine is intestinal polyps, which are caused by the lining of the intestinal tract. It is common in many people, especially those who are 50 years old or older. People with intestinal polyps are at risk of developing colon cancer and often must complete laboratory tests to make sure no cancer is present. Polyps that are larger than 0.39 inches (1 cm) are a potential sign of cancer. Rectal bleeding is often the most common sign that there are polyps in the large intestine.

Crohn's disease is inflammation of the intestines, often leading to ulcers. People with Crohn's disease often experience pain in the large intestine, and the disease is concentrated in the beginning of the large intestine. There is no known cause, but it is often hereditary. Some of the symptoms include stomach pain, diarrhea, and rapid weight loss. People experiencing a fever, weak pulse, or severe stomach pain are often advised to seek immediate medical attention.

One treatment for large intestine pain is anti-inflammatory medication, which can relieve pain when inflammation is reduced. Analgesics are medications that focus on pain relief. Some natural remedies include a warm bath and massage to overcome mild symptoms. A colonoscopy is often recommended in patients with polyps, and during that procedure, polyps can be removed from the large intestine with an electrocautery box or biopsy forceps. Patients are often anesthetized during some procedures to remove polyps.
