ROACH: Symptoms of collagenous colitis hard to live with

DEAR DR. ROACH: I have a rare type of colitis called collagenous colitis. The latest episode was set off two and a half years ago, when I took statins for a short time. I have not been able to get it under control since then. Asacol has not been successful, although it did work in the past. The only thing that seems to work now is budesonide, which is terribly expensive and causes weight gain. Any suggestions? — D.W.

ANSWER: Collagenous colitis causes watery diarrhea, and it can be triggered by certain medications, especially anti-inflammatory drugs, but also statins. Fortunately, it is not life-threatening and doesn't lead to cancer, but the symptoms can be difficult to live with.

Budesonide is considered the most effective treatment. Other options include sulfasalazine (a relative of Asacol) and cholestyramine. Prednisone is much cheaper than budesonide, but doesn't work as well and has even more side effects. Some people with collagenous colitis also have celiac disease, so it might be worthwhile to get tested.

DEAR DR. ROACH: I recently read that drinking beet-root juice helps to increase nitric oxide in the blood. This could increase blood flow in the penis, to help with erectile dysfunction. My question is: How much should one consume to achieve the maximum effect? My weight is 180, and my health is good. — S.K.R.

ANSWER: Beet-root juice, or even a diet high in vegetables, is sufficient to increase levels of nitrate, which can be converted by bacteria to nitrite, which is absorbed into the blood. Blood nitrite then increases nitric oxide, in theory improving blood flow, which could possibly help erectile dysfunction. I could not find a single study confirming that (or even evaluating if) beet-root juice is effective for this indication, even though the theory makes sense. Studies on beet-root juice improving blood flow in athletes shows mixed results — some people are helped; some aren't.

  • Do your genes make you procrastinate?

    Procrastinators, in my experience, like nothing better than explaining away their procrastination: General busyness, fear of failure, and simple laziness are just a handful of the excuses and theories often tossed around.

  • Kids get codeine in ER despite risks, guidelines

    Despite recommended limits on codeine use in children, the potent painkiller is prescribed for children in at least half a million emergency room visits each year, a study suggests.

    Use of the drug in that setting is hardly rampant — just 3 percent of kids' ER visits resulted in a codeine prescription in 2010, the 10-year study found. But with more than 25 million ER visits by children each year, the authors say far too many kids are getting the drug when better options are available.
