Light bladder leakage (LBL), also known as urinary incontinence, is a common condition that affects people of all ages, including women under 30. According to the National Association for Continence, about 25% of women under the age of 30 experience some form of LBL. The exact number of women under 30 who have LBL can vary depending on a number of factors, including overall health, pregnancy and childbirth history, and lifestyle habits.

It's also worth noting that LBL can be caused by a variety of factors, including pregnancy, childbirth, menopause, and certain medical conditions. If you think you have LBL, it is important to consult with a healthcare professional to determine the underlying cause and develop an appropriate treatment plan.
