False about Blind loop syndrome
**Core Concept**
Blind loop syndrome is a condition characterized by the malabsorption of nutrients due to a segment of small intestine being bypassed, leading to bacterial overgrowth and impaired nutrient absorption. This condition often occurs in patients with intestinal obstruction or after surgical procedures that create a blind loop.
**Why the Correct Answer is Right**
The correct answer is related to the pathophysiology of blind loop syndrome. The condition is caused by the accumulation of bacteria in the bypassed segment of the intestine, leading to the production of toxic substances that impair nutrient absorption. The bacterial overgrowth is a result of the absence of normal peristalsis and the presence of a stagnant environment that allows bacteria to multiply.
**Why Each Wrong Option is Incorrect**
**Option A:** Blind loop syndrome is not typically associated with increased risk of bleeding. While malabsorption can lead to deficiencies in vitamin K, which is necessary for blood clotting, the primary concern in blind loop syndrome is malabsorption of nutrients, not bleeding.
**Option B:** Blind loop syndrome is not primarily caused by an imbalance of gut flora. While an imbalance of gut flora can contribute to various gastrointestinal disorders, blind loop syndrome is specifically caused by the overgrowth of bacteria in a stagnant segment of the intestine.
**Option C:** Blind loop syndrome is not typically associated with an increase in intestinal motility. In fact, the condition is often caused by a decrease in intestinal motility due to the obstruction or surgical procedure.
**Clinical Pearl / High-Yield Fact**
A key feature of blind loop syndrome is the presence of steatorrhea (fatty stools) due to the malabsorption of fats and fat-soluble vitamins. This is a classic clinical presentation that should raise suspicion for blind loop syndrome.
**Correct Answer:** C.
