Infants given antibiotics may face an increased risk for obesity
later in childhood. NYU researchers studied 11,000 young
children. They looked at their weight and antibiotic use
throughout childhood. They found those given antibiotics between
birth and five months were 20 percent more likely to be
overweight by the time they turned three. Experts say this
doesn't prove antibiotics cause obesity, but it suggests the
bacteria in our gut may be permanently changed if exposed to
antibiotics early in life. The researchers are planning more
studies.
