What symptom is commonly associated with irritable bowel syndrome (IBS)?

Abdominal pain is commonly associated with irritable bowel syndrome (IBS), as it is one of the hallmark symptoms of the condition. People with IBS often experience discomfort or cramping in the abdomen, which can vary in intensity and may be relieved after a bowel movement. This pain can be associated with changes in bowel habits, such as diarrhea, constipation, or alternating between both, which also reflects the dysfunction in the digestive process characteristic of IBS.

In contrast, persistent vomiting is not typically a symptom of IBS but may be associated with other gastrointestinal disorders. Frequent diarrhea alone does not encompass the full range of symptoms seen in IBS, as many individuals also deal with constipation or alternating bowel patterns. Consistent weight gain is not directly associated with IBS; in fact, many individuals with IBS may experience weight fluctuations due to the changes in their eating patterns and gastrointestinal function.
