While hormonal birth control doesn’t typically link directly to OAB, it may contribute to certain urinary symptoms.
Synthetic estrogen and progesterone can influence fluid retention, pelvic floor muscle function, and bladder activity. This may lead to symptoms like increased urgency or frequency when urinating, which are common characteristics of OAB.
Nonhormonal contraceptives, including copper intrauterine devices (IUDs) and barrier methods, are less likely to affect bladder function.
However, some people may experience bladder symptoms related to pelvic muscle stress or urinary tract infections associated with the use of a diaphragm or IUD.
You may be more likely to develop OAB if you have a history of pregnancy and childbirth. Other medications and underlying health conditions can also affect your risk of OAB.
If you notice urinary symptoms after starting birth control, consider making an appointment with a healthcare professional.
They can confirm whether your contraceptive is at the root of your symptoms and, if needed, recommend an alternative.
