Dear Dr. Roach: I must admit that I sit on the throne (toilet) for too long for my morning (or evening) constitutional, maybe 15 minutes or so. But I am busy with my crossword puzzles its about the only time I can carve out for my little obsession.
The problem is, my legs almost always fall deeply asleep. This happens frequently. Im wondering if I should cease this practice. Could I be doing damage to my nervous system? The tingling goes away after I walk around a bit, and there are no lasting effects. V.K.C.
Answer: Id recommend finding a different place to do your crossword puzzles.
I dont recommend anyone sit on the toilet too long. Pressure in the colon from prolonged sitting (I dont say you are necessarily straining, but I suspect that like most people you have increased pressure in the colon from sitting on the toilet) increases the risk of colon problems, both common (diverticulosis, outpouchings in the colon wall) and rare (volvulus, a twisting of the colon that is a surgical urgency). When you have the urge to go, you should take yourself to the bathroom and do so. If you are straining, its time to add more fruits, vegetables and fiber to your diet.
The numbness in your legs is not uncommon. The position of a toilet seat may put extra pressure on the nerves of the leg, especially the sciatic nerves. This pressure is what is causing the numbness. The fact that there are no long-term symptoms suggests no lasting damage, but I would argue this is your body telling you not to stay in that position.
Find a comfortable chair in which to do your crosswords, and ignore the world for a little while.
