Introduction
Redundant sigmoid colon refers to an abnormally increased length of the sigmoid colon, which may be caused by developmental abnormalities, aging, chronic constipation, and other factors. Patients mainly experience symptoms such as constipation, abdominal pain, and bloating. After diagnosis, dietary habits should be improved promptly, with an emphasis on清淡, low-fat, high-fiber foods. If the condition is severe, timely medication treatment should be administered according to medical advice.

In general, a long colon is referred to as sigmoid colon elongation, which means the length of the sigmoid colon exceeds the normal range. If discomfort occurs, timely medical consultation is recommended. Detailed analysis is as follows:

Under normal circumstances, the length of the sigmoid colon in adults ranges between 40 to 60 centimeters. If the measured result exceeds this maximum value, it indicates an elongated sigmoid colon, known as sigmoid colon elongation. This condition is usually associated with abnormal intestinal development during the embryonic period, aging, chronic constipation, and other factors. These causes may weaken the function of the sigmoid colon, thus affecting normal digestion and leading to sigmoid colon elongation.

Common symptoms of sigmoid colon elongation include constipation, abdominal pain, bloating, weight loss, decreased body weight, inability to pass gas, and even reduced appetite.

After diagnosis of sigmoid colon elongation, it is recommended to promptly improve unhealthy dietary habits, aiming for a light, low-fat, high-fiber diet. Medications such as domperidone tablets, levofloxacin hydrochloride capsules, and Bifidobacterium triple viable powder may be used under medical guidance for treatment.

Sigmoid colon elongation can be cured with timely treatment. However, neglecting the condition may lead to more severe complications. Therefore, it is recommended to undergo timely and standardized treatment after diagnosis to avoid delays in the condition. At the same time, maintaining a positive mindset is also important to promote recovery.
