Ulcerative colitis comes with many different signs and symptoms. People who live with ulcerative colitis can suffer from painful abdominal cramps, fatigue, joint pain, dehydration, explosive and bloody diarrhea, and sometimes, they even become anemic. However, nausea and vomiting are not common symptoms of this potentially debilitating disease.
These helped my son with the nausea.
Though it is rare, some patients do experience nausea and vomiting as a part of their disease course, especially if their disease or flare-up is severe. Nausea and vomiting can happen with ulcerative colitis for a few different reasons:
Severe dehydration for any reason can cause someone to become nauseated and to vomit. People who suffer from severe ulcerative colitis or who are having a bad flare-up, can be dehydrated enough to cause nausea and vomiting.
Some patients with ulcerative colitis need to strain during the passage of diarrheal stools. This straining can cause what is known as a vaso-vagal response. During this response, pressure on the vagus nerve can cause nausea, and even fainting.
For many patients who suffer from vaso-vagal fainting, nausea is a warning sign. Even people who do not have ulcerative colitis can have nausea and fainting as a result of the vaso-vagal response, which is a malfunction of the nervous system that regulates heart rate and blood pressure. Straining to have a bowel movement can put pressure on this nerve and cause the heart rate to slow, the blood pressure to drop, and in turn a lack of blood in the brain. The final result is nausea, fainting and confusion.
Patients with severe ulcerative colitis may be suffering from malnutrition. This, in turn, can cause nausea and vomiting.
Severe pain that sometimes accompanies ulcerative colitis can cause nausea and vomiting.
Patients who are experiencing any nausea or vomiting with ulcerative colitis should discuss their symptoms with their physician. It is possible that something else could be going on, or that the doctor can prescribe something to help with the episodes of nausea and vomiting.
