Irritable bowel syndrome affects millions of Americans, many of them not even realizing that the symptoms they feel are not normal. Some suffer from severe constipation, while others deal with diarrhea. Other symptoms are gas and bloating. According to the Mayo Clinic, as many as 1 in 5 adults has irritable bowel syndrome.
IBS symptoms are many and are often accompanied with or include abdominal pain, diarrhea, constipation, or a feeling of incomplete bowel movement. There are four different classifications of IBS, which have slightly different symptoms. IBS-D has diarrhea as its predominant symptom. IBS-C is characterized by constipation as its primary symptom. Thirdly IBS-A is named for the acute pain a patient feels as the most predominant of the IBS symptoms. Lastly IBS-PI is named for the fact that the onset of IBS symptoms closely follows an infectious disease the patient has had. Fever, vomiting, diarrhea, or a positive stool culture often characterizes this last form of the disease.
