Hormones also likely impact food intake over the menstrual cycle. Some people experience an increase in weight around menopause, but this is believed to be related to aging more so than hormonal changes (8,9).

The hormonal changes that occur during and after menopause cause an increase in body fat, particularly around the abdomen (8,9). Starting from puberty, estrogen causes body fat to be deposited on the chest, thighs, hips and butt (8). As it relates to birth control, some people may fear weight gain, some may desire it, and others may not consider it important at all.Ĭhanges in hormone levels during puberty and menopause can impact body composition. Even scientific measures such as body mass index (BMI) cannot adequately classify who is healthy or not. Unfortunately in some cultures, there is harmful pressure to conform to standards that may not be realistic. It’s important to note that what is considered to be an ideal weight or body type is impacted by social and cultural beliefs that are continually changing. People who report gaining weight while using hormonal birth control (such as the pill and the shot) are more likely to stop using it (5-7). Concern about side effects like weight gain keeps some people from using hormonal birth control (4). Some people may gain weight while using hormonal birth control, while others may experience bloating or changes in body composition (the amount and distribution of body fat) which could make them feel like they’re gaining weight.

A common belief people have about hormonal birth control is that it will cause weight gain (1-3).
