A new study has confirmed the theory that low doses of antibiotic drugs may alter the composition and function of the bacteria in the gut, causing weight gain through changes in metabolism.
Researchers administered sub-therapeutic antibiotic therapy to mice and a control group. After approximately six weeks, the mice receiving antibiotics had gained around 10% to 15% more fat mass than the mice not receiving antibiotics.
While further research is required to confirm the theory, the manipulation of gut microbome may have implications for future obesity treatment and other conditions affected by the functions of bacteria in the gut.
