Yes, it can help with cramping, but only if you take it consistently. I am not a doctor, but my opinion is your gastroenterologist has it wrong. Bile has to have food to "work on." If you're eating during the day, the "danger" occurs at night, because you're no longer eating, but still manufacturing bile. I was told to take mine at bed time.
I mix mine with an organic papaya nectar which is a mix of various fruit juices. About 6 ounces of liquid, 1/2 water and 1/2 juice. Mix it in a small bottle and shake it up till it blends. Drink it lukewarm. That's because cold liquids can induce cramping, especially if your intestines have been traumatized for a long time.
If you're taking substances such as digestive enzymes or ox bile, or even vitamins, stop. Find a good probiotic and take it with your noon meal. I believe that too much bile destroys the bacterial balance needed for digestion. Questran will bind any other medication you have been prescribed and render it useless. So if you take prescription meds take them 1 hour before you take the Questran.
You also need to rebuild the contents of your intestines. I made a mixture of white rice (2 cups), drained canned organic chicken (3-4 ounces) and chicken broth. Ate about a cup, slowly, every 3-4 hours. Did that over a period of 4 days till stuff calmed down.
Then I started the brat diet, bananas, rice, applesauce and toast. I can eat butter from grass fed cows, so I use it on my toast. A certain amount of fat is necessary to enable absorption of nutrients. I use a dab of butter, olive oil or coconut oil for cooking. I eat low fat meats, no sausage, or bacon. When you try out a vegetable, try it in very small amounts.
Eventually, you'll be able to incorporate more foods in your diet. I still use Immodium from time to time, but I don't take it daily.
Try to have confidence that you'll be able to figure out what works for you. It takes at least 3-4 days before the Questran starts to help. Right now, because of the excess bile, your body's processing food at an alarming rate. It should take about 3 days for the food you eat to move through your digestive system. Right now, you're not getting the nutrition you need because everything you eat is zooming through.
Best of luck to you. xx
