Antibiotic whether or not antibiotics cause obesity in humans. Studies have found a correlation between early exposure of antibiotics (<6 months) and increased body mass (at 10 and 20 months).

Therefore, there is correlation between antibiotic exposure in early life and obesity in humans, but whether or not there is a causal relationship remains unclear. Although there is a correlation between antibiotic use in early life and obesity, the effect of antibiotics on
Antibiotic Resistance Lab Network Antibiotic Resistance Lab Network The Antibiotic Resistance Lab Network (ARLN) is a group of laboratories of the United States Centers for Disease Control and Prevention established to supplement the work of local and state public health laboratories in the identification and research of antibiotic resistance.
