Patient Comments: Melanosis Coli - Symptoms and Diagnosis

What symptoms, if any, did you experience with melanosis coli, and how were you diagnosed?

Comment from: M., 45-54 Female (Patient) Published: January 25

I had my very first routine colonoscopy today with no polyps but was diagnosed with melanosis coli. The doctor asked if I take laxatives or herbal teas and was somewhat surprised when I said no to both. I have never taken a laxative in all 50 years of my life and don't drink much tea. However I told him that I do add natural aloe vera (which apparently has laxative effects) to my smoothies at least once a week. He said that's probably the cause; he told me to stop taking aloe vera. I will but also plan to conduct further research because aloe has such great health benefits.

I had a colonoscopy two days ago which revealed melanosis coli. I probably have used a laxative twice in ten years and only about eight months ago changed to drinking herbal teas (Yogi). Without using laxatives I really question how I have this.

Pseudomelanosis coli gives the symptoms like mucus colitis. Frequent stools with mucus (no blood), colicky pain, gaseous distention of colons and tender colons are noted in a few patients, which prompted me to ask for colonoscopy, which turned out pseudomelanosis coli.

I see that many others here also never used laxatives and were told they had melanosis coli. I had my colonoscopy 4 years ago and the very unpleasant doctor accused me of overuse of laxatives. I asked her if this might actually be endometriosis because I've had that and struggled with that my entire life. I have never had a need for laxatives because I have never been constipated. She snickered at me and insisted that I was lying. My son is in the medical field and said, 'yes, people say that all the time that they don't use laxatives'. I wonder if anyone has thought that it might be from something else! This makes me so angry to be treated this way.

I had a colonoscopy this week and was told that I have melanosis coli. I am confused as I do not use laxatives.

I too was diagnosed with melanosis coli. I have been taking colon cleanse for several years. I was instructed to stop taking it.

I was diagnosed with melanosis coli, yesterday during my colonoscopy. After reading the causes, I have never used laxatives (per se) but have used a product labeled 'colon cleanse.' I wonder if they are one and the same. My uses of this product has been twice in five months. I will definitely stop using the product but it would be a great idea if warnings of this nature were displayed on product labels.

I was diagnosed with melanosis coli from a colonoscopy I had done just yesterday. I did not know what it was so I looked it up. I do not or have not taken laxatives ever, so I don't know how I got this.
