Signs and Symptoms of an Impacted Colon. Because pressure is being placed on your abdomen, impaction can cause a loss of appetite. You will gain weight because the waste accumulates in your body and it has nowhere to go. When and if you decide to use a colon cleanser, you might lose several pounds.
Occasionally, long-term constipation develops into fecal impaction, which is a blocked colon from a mass of stool that can't be moved by colon contractions. Fecal impaction can cause pain and vomiting, and a person with fecal impaction may require emergency treatment or hospitalization. Fecal impaction is a fairly common complication of long-term constipation in the elderly and bedridden, occurring in about 30% of all nursing home residents. Symptoms. Symptoms of constipation include: 1  Fewer than three bowel movements per week. 2  Small, hard, dry stools that are difficult or painful to pass. 3  The need to strain excessively to have a bowel movement. 4  A feeling that your rectum is not empty after a bowel movement. 5  Frequent use of enemas, laxatives or suppositories.
