Question: What Is a Controlled Experiment? One of the most common types of experiment is a controlled experiment. Here is a look at what a controlled experiment is and why this type of experiment is so popular in science. Answer: A controlled experiment is one in which everything is held constant except for one variable.
Symptoms of inflammatory bowel disease (IBD), including ulcerative colitis and Crohnâs disease, primarily affect the digestive tract and include appetite loss, diarrhea, weight loss, rectal bleeding, nausea, and abdominal cramping.
Nausea and vomiting commonly occur with any dysfunction of the digestive tract but are particularly common with gastroenteritis (see Gastroenteritis). A less common digestive tract disorder is obstruction of the intestine, which causes vomiting because food and fluids back up into the stomach because of the obstruction.
