It is critical that you get in to see your gastroenterologist
as soon as possible. As you know Crohn's disease is a condition that tends to relapse, resulting in multiple complications over the lifespan. In your case, you have already had two surgeries, for example.
There are several possibilities for your uncontrollable nausea, but a worsening of your Crohn's disease needs to be considered. Especially if you are having worsening abdominal pain
, blood in your stools, weight loss, or other usual symptoms associated with a Crohn's flare.
The other possibility, as you mention, would be a problem with a stricture or scar tissue. This tissue can cause an obstruction of the intestine, usually of the small intestine. This can lead to periodic pain, abdominal bloating, and inability to move through intestinal contents, leading to vomiting
Your gastroenterologist will be able to help you determine what is going on. It may be necessary to have a repeat endoscopy, or you may need radiologic imaging of your abdomen or blood work to determine how inflamed your system is right now. I the meantime, if you experience any severe abdominal pain or bloating, or intractable nausea and vomiting, you should go to the emergency room.
