Women need to avoid pregnancy for 12 months after bariatric surgery
A study presented at this year s European Congress on Obesity (held online, 10-13 May) supports recommendations to avoid pregnancy for 12 months after bariatric (obesity) surgery due to an association with adverse outcomes in pregnancy including an elevated risk of preterm birth. The study is by Dr Laura Heusschen, Vitalys Obesity Clinic, part of Rijnstate Hospital, Arnhem, The Netherlands, and colleagues.
More than half of all female patients who undergo bariatric surgery are of reproductive age, and the resulting weight loss improves fertility, as well as reducing the risk of gestational diabetes and hypertensive disorders during pregnancy. It also lowers the chance of the baby having a high birth weight, which is associated with an increased risk of complications for both mother and child.

The first global review of complementary medicines (herbal and dietary supplements) for weight loss in 16 years combining 121 randomised placebo-controlled trials including nearly 10,000 adults suggests that their use cannot be justified based on the current evidence.
The findings of two studies, being presented at The European Congress on Obesity (ECO) held online this year, suggest that although some herbal and dietary supplements show statistically greater weight loss than placebo, it is not enough to benefit health, and the authors call for more research into their long-term safety. Over-the-counter herbal and dietary supplements promoted for weight loss are increasingly popular, but unlike pharmaceutical drugs, clinical evidence for their safety and effectiveness is not required before they hit the market , says lead author Erica Bessell from the University of Sydney in Australia. Our rigorous assessment of the best available evidence finds that there is insuffici

There is insufficient evidence to justify recommending herbal and dietary supplements to help people to lose weight.
That is the emphatic view of researchers who are to present studies on the effectiveness of supplements at the European Congress on Obesity online this week.
“Even though most supplements appear safe for short-term consumption, they are not going to provide weight loss that is clinically meaningful,” said lead author Erica Bessell of the University of Sydney in Australia.
Herbal supplements contain whole plants or combinations of plants, while dietary supplements contain naturally occurring single compounds. They can be purchased as pills, powders and liquids and have become increasingly popular as aids to losing weight.

Obesity increases the risk of developing 10 of the most common cancers, regardless of how it is measured, according to a study of more than 400,000 adults in the UK, being presented at The European Congress on Obesity (ECO) held online this year, with central fatness (larger waist and hips) and general obesity (body mass index [BMI] and body fat percentage) associated with similar estimates of cancer risk.
The results suggest that BMI is an adequate measure of cancer risk from excess weight, and there is no advantage in using more complicated or expensive measures such as waist circumference or body fat percentage.
