it might be a digestive issue, not necessarily Crohn's. Was your blood tested for ANA levels. Well, even ANA positive is not a conclusive test for any Auto-immune disease.
What I see is you are already confused & worried. It is only normal for a person to feel that way and to start worrying about the worst case screnario. Have the faith that you will be better soon and include some relaxation time in your daily routine. Let the docotors take care of the body, while you stay positive & emotionally strong. Keep writing in.
The only medications I'm taking are prilosec and an equate brand nonlaxative stool softener.
Digestive problems may cause green stool. If a body is not properly digesting the food correctly, the food particles will not be absorbed into the intestines, leaving colored stools. Bile salts that are not properly processed through the intestines can also cause dark green stools.
Some antibiotics may cause the stool to change color. The bacterial levels are changed due to the introduction of a medicine and the stool color will most likely be affected. These stool color changes should only be temporary and subside when the medicine is stopped.
Other illnesses like celiac disease, irritable bowel syndrome and ulcerative colitis can cause green stool. These illnesses will need to be treated by a doctor. A person may also pass green stool if their body is starving, or just not getting the nutrients it needs.
