Lactobacillus GG has been studied in regard to which property?

• A. Antidiarrheal properties
• B. Treatment of NEC
• C. Eradication of Helicobacter pylori
• D. Weight gain with probiotics

Answer: (A)

Probiotics such as Lactobacillus rhamnosus GG are most consistently studied for antidiarrheal effects. The strain helps restore and maintain the gut microbiota after disruption from antibiotics or illness, strengthens the intestinal barrier, and modulates the immune response, which can reduce the risk and duration of diarrhea. Clinically, this translates into fewer episodes of antibiotic-associated diarrhea and infectious diarrhea, especially in children. While there is interest in using this probiotic for other issues—such as NEC prevention in preterm infants, potential adjunctive roles in H. pylori eradication, or effects on weight gain—the strongest and most consistently demonstrated evidence centers on its antidiarrheal properties, making that the best-aligned answer.
