What causes Melanosis in colon?
What causes melanosis coli? Melanosis coli usually results from chronic use of laxatives of the anthranoid group. Some examples of anthranoid laxatives are senna (sennosides; Senocot, Senokot EXTRA and others) and rhubarb derivatives.
Is Melanosis a cancer?
Cancer Risk Most gastroenterologists consider melanosis coli to be a harmless condition. Studies have not found an association between melanosis coli and an increased risk of colorectal cancer in humans.
How long does it take to develop melanosis coli?
The appearance may vary throughout the colon on the basis of the pigmentation strength or the amount of absorption of the laxative. Furthermore, development of melanosis coli can occur 4 to 12 months after chronic laxative use.
Is melanosis coli common?
Melanosis Coli is a common condition characterized by brown or black pigmentation of colonic mucosa. The condition itself is asymptomatic and the diagnosis is usually made on incidental endoscopic or histological findings.
Does Melanosis go away?
Melanosis coli treatment There is no treatment for melanosis coli. According to research published in the British Medical Journal, it’s generally reversible within 6 to 12 months after a person stops using anthraquinone-containing laxatives.
Which drug causes melanosis coli?

Does laxatives cause Melanosis?

Can laxatives cause colon polyps?
The multivariate RRs associated with weekly to daily laxative use compared to never use were 0.9 (95% CI: 0.7-1.1) for total colorectal adenomatous polyps, 1.0 (95% CI: 0.7-1.5) for large adenomas and 0.8 (95% CI: 0.6-1.2) for colon adenomatous polyps only.
Can miralax cause melanosis coli?
Chronic, sustained use of stimulant laxatives also correlates with the development of a condition called melanosis coli, in which the cells of the colon wall become damaged and die. This cell death can take place in the course of just a few months of laxative use.
What is Melanosis colon?
Melanosis coli is a condition usually associated with chronic laxative use in which dark pigment is deposited in the lamina propria of the colon5. The pigment deposition results in a distinctive dark brown to black staining of the lining of the large intestine.

How is a diagnosis of Melanosis coli made?
Diagnosis is typically made by colonoscopy. Discontinuing laxative use usually leads to resolution of melanosis coli. Melanosis coli is not associated with an increased risk of colon cancer.
Do you need a colonoscopy for melanosis coli?
A colonoscopy is a procedure used to check the colon for signs of cancer or other problems. A scope is inserted into the anus and guided up into the colon. Melanosis coli does not need to be treated. You will need to stop using laxatives regularly. What can I do to prevent constipation?
