Hello and welcome to E health Forum.
The redundant colon refers to extra twists or loops in the large intestine (usually the descending colon).
Long term chronic constipation and bowel disorders could be the cause of your condition.
Unless and until, you are asymptomatic and do not have major bowel alterations, there is no need for therapy.
But presence of such a dilated and tortuous colon can cause it to get twisted on itself causing complications like perforation, acute volvulus, etc. Such complications present as severe abdominal pain, and need emergency medical treatment and surgical interventions.
Hence it is advised to remove the excess of colon loops by a colectomy.
You may consult with your doctor, who can provide you additional information and also help you make a treatment plan for you.
I hope this helps.
