Could this be IBS. Please help!!!!

A little back story, I suffered from a moderate hiatal hernia and severe GERD. 7 weeks ago I had a Nissen Fundoplication. Basically the top 1/3 of my stomach was twisted around my esophagus to support my LES (lower esophageal sphincter). Since my surgery I can not have a bowel movement! My surgeon thinks they are unrelated. He said that if I had even a small case of IBS this surgery could exacerbate the issue. I take colace 100mg twice per day, Miralax 17gm twice per day and a fleet enema about day 7 of no BM. I was hospitalized a few days ago because I was so backed up with feces that my duodenum ballooned with gas and was near perforation. I don't know what is going on or how to treat this naturally. I do not want to be laxative dependent from long term use!!! Any advise?

I can not get into the GI until the end of august and no to the pain meds. I was off of those by the end of week 3. I have also noted some crazy hot flashes. Mostly when i start to feel backed up!

You should definitely take magnesium daily. Preferably Elemental because it's more easily absorbed and my doctor told me it can cross the blood brain barrier. Basically it'll work faster. Magnesium is a natural muscle relaxant and if you take it daily it really helps keep you regular. Also most people don't get enough magnesium. Adult recommended daily dose is 310 mg, but considering your situation I'd take more at first. If you reach the point you have loose watery stools then just take a little less. I have all kinds of digestive and pain issues and magnesium really helps if I'm consistent.
