General Colon Bowel! Hilarious name!
Anyway, I too have a juicer which has come in extremely handy. Like you, my body wasn't absorbing nutrients, and eating raw fruits and veggies was wwaaayyy out of the question. The juicer I have is the Breville Juice Fountain Elite. It's great! It juicing everything from ginger, to apples (with skins), to beets, etc. When I first started juicing my poo was the color of my juice drinks. It still happens every now and then!. I can now digest raw fruits and veggies but still make plenty of juice drinks as it is much easier than eating everything raw!
The juicer especially comes in handy when I feel like I'm getting sick! I juice tons of ginger, which fights off the sickness! It's crazy spicy, and will make your pores
open up, but will help fight off/kill any virus that is trying to invade your body! It has helped my family members out too when they were also getting sick (we have all learned to deal with the spicy ginger drink).
In my opinion, I think it is GREAT that you are working out. I jumped back on my bike three weeks after being hospitalized for almost two weeks attached to TPN. It has been as important to me as my meds. Exercising will help calm your mind, and will definitely help your body! Think of it as "killing your Crohn's" by sweating it out of your body. That's what I think anyway! The only frustrating aspect I had to deal with while working out is that my body wasn't nearly as strong as I expected it to be (I was getting destroyed in group bike rides/races). Once I accepted that, and realized that it was going to take me time, I changed my mindset. I think working out is a definite MUST!! Just listen to your body and don't overdue it!
I hope everything works out for you!! Take care!!
