Obesity is having an excessive amount of body fat in relation to lean body mass that may impair health.
The primary cause is an energy imbalance between calories consumed and expended.
Treatment goals include to lose 5-10% of body weight or 0.5-1 kg (1-2 lb)/week for 6 months and regain of <3 kg in 2 years and sustained reduction of waist circumference of at least 4 cm.
Strategies are aiming for realistic goals and a multidisciplinary approach that is a combination of dietary change, physical activity and behavioral modification.
Individuals with obesity are at an elevated risk of developing infections, particularly that of the skin in both men and women, and those of the gastrointestinal and urinary tracts and sepsis in women only, according to a study.
Obesity at any age in adulthood doubles the risk of having poor physical functioning in midlife, with body mass index gains over much of the life course and prolonged exposure to obesity contributing to the risk, according to a study.
Teens with severe obesity need not wait until they are adults to undergo Roux-en-Y gastric bypass, with 5-year follow-up data from a recent study showing that the bariatric procedure leads to substantial weight loss that is similar in magnitude in adolescents and adults.
The risk of nonvertebral fractures is dependent on type of bariatric surgery, with a higher risk in patients with severe obesity who undergo Roux-en-Y gastric bypass (RYGB) compared with adjustable gastric banding (AGB), according to a recent retrospective study.
Laparoscopic sleeve gastrectomy is useful for treating severe obesity in adolescents with cognitive impairment or developmental disability, according to a study, suggesting that bariatric surgery should be considered for young people, regardless of intellectual ability.
One anastomosis gastric bypass is as effective as the standard Roux-en-Y procedure in terms of weight loss and metabolic improvements 24 months after the surgery, according to the results of the open-label YOMEGA trial.
Oral supplementation with probiotics or synbiotics leads to a reduction in waist circumference of overweight or obese adults, although the effect size is small and may be clinically insignificant, according to the results of a systematic review and meta-analysis.
Long-term testosterone therapy in obese men with hypogonadism led to sustained weight loss and improvements in multiple anthropometric parameters, according to an observational study presented at ENDO 2019.
About one-third of individuals who achieved remission of type 2 diabetes (T2D) after losing weight with an intensive weight management programme sustained their remission at 2 years, according to long-term results of the DiRECT* trial.
Progressive lipolysis may be reduced via the improved antilipolytic effect in adipose tissue, which leads to a reduction in future weight loss caused by sodium-glucose cotransporter 2 inhibitors (SGLT2is) in patients with type 2 diabetes (T2D), suggests a recent study.
Maternal prepregnancy obesity is associated with earlier age at voice break, pubic hair development, axillary hair and acne in sons, as well as with earlier age at menarche, breast development, pubic hair development, axillary hair and acne in daughters, a study has found. These associations appear to be mediated by higher childhood body mass index in sons and partly so in daughters.
