The study was conducted in 54 adult patients with Giardia lamblia infection and 54 adult controls to detect lactose maldigestion employing the noninvasive lactose hydrogen breath test. Forty of 54 (74%) patients with Giardia lamblia and 24 of 54 (44.4%) controls showed lactose maldigestion (P < 0.01). In conclusion, this study shows that the frequency of lactose maldigestion is significantly higher in adult Indians suffering from Giardia lamblia infection compared to healthy individuals.
