Colon Polyps Many times, people are not aware they have colon polyps because there are no symptoms. Larger growths can bleed, causing blood in the stool. Sometimes bleeding polyps can cause fatigue and other symptoms of anemia (low levels of red blood cells). On rare occasions, a large polyp can cause diarrhea or secretion of large amounts of potassium. This can cause marked fatigue and muscle weakness. Diagnosis

Complications of Cirrhosis Portal hypertension is associated with splenomegaly and hence hypersplenism and the development of collateral vessels lining the esophagus and stomach, producing varices. Esophageal varices and, less often, gastric varices are particularly prone to bleeding, which is often massive.

Esophageal Varices Esophageal varices almost always occur in people who have cirrhosis of the liver. Cirrhosis causes scarring of the liver, which slows the flow of blood through the liver. Scarring causes blood to back up in the portal vein, the main vein that delivers blood from the stomach and intestines to the liver.

What is Colon Cancer? Colon cancer is a malignancy that begins in the colon or large intestine. The large intestine is a long tube-like organ near the end of the digestive system. After food passes through the stomach and small intestine, the colon is responsible for removing fluid and some nutrients from the food you eat.

Colorectal Cancer Colorectal cancer (CRC) is a rapid abnormal cell growth that affects the large intestines and/or rectum. These clusters of cells are called adenomatous polyps and develop from the tissue membrane of glandular tissue.

Bleeding esophageal varices Scarring (cirrhosis) of the liver is the most common cause of esophageal varices. This scarring cuts down on blood flowing through the liver. As a result, more blood flows through the veins of the esophagus. The extra blood flow causes the veins in the esophagus to balloon outward. Heavy bleeding can occur if the veins break open.

Esophageal Varices Less common causes of portal hypertension and esophageal varices include blood clots in the veins leading to and from the liver and schistosomiasis. Schistosomiasis is a parasitic infection that can clog up the liver, causing pressure to back up in the portal vein.

Hemorrhoids Hemorrhoids are not arteries or veins, but instead are normal blood vessels called sinusoids that are located in the walls that surround the rectum and anus. When the venous pressure within these blood vessels increases, the hemorrhoids swell and dilate, because it is more difficult for blood to empty from them.

- A hemorrhoid is an enlarged vein in the anus (it's also called a varicose vein). In a healthy person, the tissue around the anus fills with blood to regulate bowel movements. However, when there is constant pressure restricting blood flow, the veins become inflamed. Poor blood flow may cause a blood clot.

- Although varices may form in any location along the tubular gastrointestinal tract, they most often appear in the distal few centimeters of the esophagus. Approximately 50% of patients with cirrhosis develop gastroesophageal varices. Gastric varices are present in 5–33% of patients with portal hypertension. The frequency of esophageal varices varies from 30% to 70% in patients with cirrhosis (Table 1), and 9–36% of patients have what are known as “high-risk” varices.
