Thanks to your hormones, your vocal cords become thicker and harder, which changes the tone and pitch of the voice. This transition period can last six months or even two years. In general, teenage girls tend to experience weight gain immediately before the onset of their periods while boys tend to lose weight and gain muscles. Testosterone, the male hormone, melts always fat, and estrogen, the female hormone, moves fat to your breasts and hips. It's nothing to be concerned about.
Weight gain is a normal part of growing up.
Because of their hormones, girls tend to gain more weight and fat than boys do naturally. However, if you enter puberty overweight you're more likely to continue to gain weight throughout puberty, especially if at least one family member is also overweight. Anhalt says there are many definitions of being overweight, so it's up to your pediatrician to determine whether the weight you're gaining is at an excessive rate in proportion to your height.
