I had my takedown at the end of February this year. Needed supplies were few. You may need some supplies for cleaning and dressing the surgical site. Calmoseptine or similar product is useful to prevent butt burn and Balneol is very good and soothing for cleansing.
It took my system some time to adjust so be patient. A pro-biotic is a must. My doctor prescribed VSL#3 but it was too strong for me. It made me quite ill so I use something less potent. It works wonders for some, we're all different. I also take Lomotil. At first it was two tablets four times per day. Now two in the morning and two at bedtime.
You will need to adjust to different foods slowly. Some foods will really upset your system at first but improve over time. As an example Bar-b-que really made me sick for the first six months. Now I can tolerate a little but I still steer away from foods that are too fatty. Fried foods and foods that produce excess gas should be avoided as well, at least at first. In time once in a while is okay. I ate Mexican food today
My systems a little off this evening but as my doctor says, sometimes you just have to decide if it's worth it.
I did have an abscess develop at the surgical site about three months after the takedown. Emergency surgery was required and my summer vacation plans were blown but that's the way it goes. Glad it didn't happen while in the middle of the Caribbean.
There are good days and not so good days but there all better than an ostomy day! It takes time but improves week by week, month by month. Take your time, relax, be patient, be mindful of your diet, take your meds and get some exercise. Walking does wonders for your GI system. Oh, there are some tea blends just for digestive health that are great. Check the organic isle at your grocery.
You'll be fine.
