Antibiotics and increased weight gain

New research from the United States (US) has added to the theory that antibiotics can disrupt people’s gut bacteria causing them to put on weight. The research which has been published in Nature looked at the effect of adding low doses of antibiotics to the diets of lab mice. The mice were found to have increased body fat and also changes to the bacteria in their gut. The researchers also found changes in some genes which are linked to breaking down carbohydrates and regulating cholesterol levels.

The researchers point out how antibiotics given in low doses have been widely used as growth promoters in the agricultural industry since the 1950s in the US, and question whether there could be a similar effect in humans when exposed to low doses of antibiotics over a long period of time. This hypothesis is still a theory and requires more research. Read more about the research in Nature.
