Post Date: 12/5/11 9:19 am Hi there. I'm not sure what surgery the previous posters had done - for me it was the RNY in April 2008. Right from the start I had issues with constipation. I used to use Milk of Magnesia on an as needed basis. It did work. Most of you know I ended up sick and then with Emergency laparotomy to repair a Petersen's Hernia in Aug 2009. In the weeks I was unwell, then really sick before I ended up in surgery - I felt as if I was more constipated that usual - and during my one short hospital stay - my surgeon (no surgery that time - I settled a bit) - who is a very smart man - told me I should NEVER take Milk of Magnesia or dulcolax or any stimulant. He recommended just softeners. So - I have been taking 2 Colace (docusate sodium) 100mg each twice a day for the last few years. Even then I do have issues at times. Every now and then I take an extra Colace or two. I take the occasional swig of mineral oil - 20 - 30cc - I know it's gross - but it works. I have to be very aware of my fiber intake - fluids - never had a problem getting them in anyway, activity, definitely a factor, as it actual dietary intake of fats. I am taken by surprise every now and then and have an issue in the other direction - who knows what makes our body do certain things? So - you are not alone - there are many options, the trick is to find what works for you. And I'm not downing those of you who do use mild stimulants to help you with this issue. That route does work for so many people. I also have read many, many times that some people swear by miralax. Good luck and take care!
