Excess Weight Could Affect Onset of Puberty in Girls

Young girls with obesity generally enter puberty and begin menstruating earlier than their counterparts with a normal weight. Now new findings published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism suggest that those with excess body fat take a little longer to develop fully mature breasts and have higher reproductive hormone levels. Researchers noted that in mid- to late puberty, girls with greater total body fat registered higher levels of certain reproductive hormones, such as follicle-stimulating hormone, inhibin B and male hormones like testosterone. “In late puberty, girls with greater body fat also showed delayed breast maturation, as determined by breast ultrasound, and earlier menarche,” she added.
