Speaking of toilets, last year there was a review of fish-induced keriorrhea. I had to look that one up myself. It turns out there are a bunch of fish that store large amounts of waxy substances in their bodies, and if we eat them, the accumulation of the indigestible wax in our rectums, through consumption of these fish, engenders rectal discharges or leakage of orange or brownish-green oil.

Keriorrhea is greasy orange anal leakage. Keri is the greek word for wax.

The scientists were even nice enough to include a picture—though, sadly not in color. “…also highlighted the potential for embarrassment from stained clothing arising from the unanticipated passage of oil as an aerosol with flatulence…” So much potential for embarrassment, there have even been demonstrations demanding immediate government actions against the “fish-induced keriorrhea epidemic.”

    1. Hi Michael-I’m vegan but have very little rectal sensation and have been diagnosed with pelvic floor dysfunction (resulting in constipation). Might you have any idea as to the underlying effects of my condition. Also, might you know of what I can do to manage it? I feel as if I have tried everything. Thank you. I so appreciate the work you do!

      1. The pelvic floor is made up of a group of muscles which support the the organs (i.e., bladder, uterus, rectum) in the pelvis like a hammock or a sling. These muscles may become weakened as a result of being overweight, menopause, and/or having children. Exercises known as Kegel’s may be performed to learn how to gain better control (contraction & relaxation) of these muscles. Techniques such as biofeedback have also been shown to be beneficial. Maintaining a high fiber diet, such as a whole food, plant-based diet, is also very important in keeping the stool soft for easier elimination.

  1. This happened to me once after eating a lot of salmon sashimi. I was a bit worried at first, but I guess I wasn’t the only one. One thing that prevented this from occurring again was eating varieties of sushi that contained starches (ie. rice) instead of just the pure fish (sashimi).

    1. I’ve eaten pretty large amounts of salmon, red snapper, etc maybe close to 3/4 lb at one meal and never had that problem (nor any other time!). that large an amount though was always cooked. Raw, sushi/sashimi always smaller portions. Maybe mostly from some types of fish not commonly seen in the US?

  2. If a 60 year old vegetarian eats a lot of fruit, veggies .. Drinks a
    lot of water…walks 5 miles a day… and is still constipated? What
    next?

    1. Cyn: Is sounds to me like the 60 year old vegetarian is on the right track! I wish I walked 5 miles a day.

      But vegetarian still usually means plenty of eggs and dairy. NutritionFacts has a video showing how dairy promotes constipation. The video is talking about kids, but I don’t see why it wouldn’t relate to adults too:
      http://nutritionfacts.org/video/childhood-constipation-and-cows-milk/

      Also, if someone is calories from dairy and eggs, one is not eating healthy foods like beans, whole intact grains, veggies and fruit–all of which have fiber while dairy and eggs do not. I know you said that the person is eating veggies and fruit, but to the extent that some calories come from animal products those calories are not coming from fiber-rich plant foods.

      Finally, being vegetarian and eating lots of fruit and veggies does not preclude also eating lots of processed foods. I would expect those processed foods to be a problem constipation-wise. So, there may be room in this person’s diet to clean up a bit, replacing processed foods with healthier whole plant foods.

      I would recommend doing a search on this site and watching the videos and articles on the topics of: bowel and constipation. Here is one good article:
      http://nutritionfacts.org/2013/09/17/prunes-metamucil-or-a-plant-based-diet/

      I’m not a doctor or expert, but I think these are good ideas that are worth a shot. On going constipation is nothing to ignore and may even be related to increased breast cancer. (See videos on this site.) So, it is worth fixing.
