Are you going to have it done? It’s a 2 part surgery that you have to prepare for physically and mentally as well. The liquid diet is the worst but if you can make it through that then your GI health will improve so much more! No acid reflux or sour stomach, nausea or vomiting because with the Nissen procedure you can’t vomit which is awesome but if can’t come it comes out the other way in diarrhea but you said you have constipation issues like me so this may help you in the long run! I have IBS-CC Chronic Constipation but my colon and intestines are very narrow they said which causes the chronic constipation and the hemorrhoids but since I was diagnosed back in 2008 with this condition they put me on my miracle medication called Amitiza it has changed my life in so many ways before this medication I would go 1-2 weeks without a BM and constant abdominal pain! I would frequently show up at the ER and be told you’re completely impacted but nothing would help no laxatives would touch it! Miralax was a joke it turns to a gel like substance in your colon that’s why they say drink lots of water with it but water would make me sick even more! I was on Senacott Mylanta, Philips Milk of Magnesium Exlax,Correctol, Sorbitol, Lactulose , suppositories, Polyglycol Metamucil, Fiber Pills, Swiss Criss, Stool Softeners nothing helped so when I went to a really good GI doctor for help she suggested that I just try the sample of the Amitiza and I was amazed at how well and fast it worked for me! Now all I do is take one 8mg capsule around 8am and it works by 11:00am or noon! This has become my daily routine since 2008 and I’m here to say that this works! No side effects no cramps it completely cleans you out! I got my dad on it because he has had chronic constipation all his life like me, and now he’s regular enjoying his life again! I take the generic for the Amitiza called Lubiprostone I’m not sure exactly what is in this medication but it saved my life because I was facing the possibility of having a Colostomy bag put in place because of my severe constipation! I was told by my GI specialist that this helps with the mechanics of my colon and it’s NOT a laxative and it will not damage my colon! I could be their spokesperson for real!😂😂 Let me know what you decide to do! Best of luck to you!😀
