Sigmoid colon redundancy can lead to stubborn constipation and therefore needs to be treated as early as possible. Sigmoid redundancy refers to the length of the sigmoid colon far exceeding the normal physiological level, resulting in excessive length in the digestive tract, which belongs to the common hereditary digestive tract malformation disease. After the onset of sigmoid redundancy, it will lead to persistent abdominal pain, abdominal distension and persistent constipation. At the same time, sigmoid colon redundancy also directly affects the digestive function. Intractable constipation generally refers to the number of bowel movements less than three times a week, while in the process of defecation there are different degrees of feces too dry, difficult or painful defecation. For intractable constipation caused by sigmoid colon redundancy, you can first use medication such as Keflex to quickly promote defecation, and you can also consider surgery to treat the cause of sigmoid colon redundancy. The sigmoid colon in the cause of intractable constipation should be timely to the hospital for digestive system examination, and consult the doctor’s advice, choose the appropriate treatment plan.
