I have been to two GI docs and one insists that I need surgery for an atonic colon while the other says absolutely not. My sitz marker test showed 7 markers left on day 3 and 1 marker left on day 5. That doesn't seem enough of a problem to require surgery to me. My question is; can anyone who has a diagnosed atonic colon please tell me what you do to have a BM without resorting to surgery. I have tried Miralax recently and it does seem to work but after about three days of taking it, I get miserable bloating and a tummy ache, so I have to stop taking it. Same problem with colace. I have a med that has cascara sagrada in it and the doc said he thinks that is too harsh, but it works for me. I don't want to become dependent on it, but worse, I don't want it to stop working if I use it too much. What do those of you with atonic colon's do to help yourselves (Short of an enema....I can't handle those)? Also, I found Triphala to be very helpful, but no one seems to know how safe it is to take long term. Anyone?
