ANTIBIOTICS & WEIGHT GAIN
Long-term treatment with antibiotic caused weight gain of 4 to 29 lbs in one-fourth of patients
One-fourth (23%) of patients treated long-term with the antibiotic, doxycycline (100 mg twice a day), plus the antimalarial drug, hydroxychloroquine (600 mg daily), gained from 4 to 29 lbs after one-year according to a study from France.
Treatment was associated with lower concentrations of three gut bacteria, Bacteroidetes, Firmicutes and Lactobacillus.
“[This suggests] that long-term doxycycline treatment lead to significant changes in weight in [some people and is associated with changes in gut bacteria],” the authors concluded.
“These results are consistent with previous studies showing that doxycycline is associated with weight gain in undernourished children in developing countries and in healthy US army recruits.”Read the entire article | Email this article

No evidence that gut bacteria plays a role in obesity
"Diets designed to achieve weight loss in obese subjects can significantly alter the species composition of the gut microbiota, but we find no evidence that the proportions of Bacteroidetes and Firmicutes [two bacteria in the gut] among fecal bacteria have a function in human obesity," the researchers concluded.

Gut bacteria different in children who become overweight compared to those who stay normal weight
Those who become overweight have only roughly half as much of bifidobacterial, but have twice as much of a Staphylococcus aureus.
"Aberrant compositional development of the gut microbiota precedes overweight, offering new possibilities for preventive and therapeutic applications in weight management," the authors of the study concluded.
While this may sound crazy, other studies have also linked gut bacteria with the risk of obesity. Read the entire article | Email this article
