Which of the following symptoms is commonly associated with intussusception?

Colicky abdominal pain is a hallmark symptom of intussusception, which is a medical condition where a part of the intestine telescopes into an adjacent segment, leading to obstruction. This type of abdominal pain is characterized by intermittent cramping that worsens and then improves, reflecting the nature of the obstruction as the intestines contract in an attempt to move contents past the blockage.

In the case of intussusception, as the bowel segment moves in and out, it can cause episodes of intense abdominal pain that can come and go, hence the term "colicky." This pain may be associated with other symptoms, but the distinctive nature of colicky pain helps differentiate it from other types of abdominal discomfort.

While the other symptoms such as fever and chills, constant lower back pain, and fatigue and nausea can occur in various abdominal or gastrointestinal conditions, they are not as specifically linked to intussusception as colicky abdominal pain is. Understanding the nature of the pain helps in recognizing and diagnosing this particular condition effectively.
