From the Research
Multiple pregnancies are significantly associated with an increased risk of hearing loss in women, as evidenced by a recent study published in 2025 1. This association is thought to be related to various physiological changes that occur during pregnancy, including hormonal fluctuations, increased blood volume, and fluid retention. While some women may experience temporary changes in hearing during pregnancy, the study found a linear increase in the odds of hearing loss with a greater number of pregnancies. The exact mechanisms underlying this association are not fully understood, but it is thought that the repeated exposure to these physiological changes may contribute to the development of hearing loss over time. It is essential for women who have had multiple pregnancies to be aware of this potential risk and to undergo regular hearing screenings to monitor their auditory health. Additionally, the use of birth control pills has been found to be associated with lower odds of hearing loss, suggesting that hormonal factors may play a role in the development of hearing loss in women 1. Overall, the current evidence suggests that multiple pregnancies may be a risk factor for hearing loss in women, and further research is needed to fully understand the underlying mechanisms and to develop effective strategies for prevention and treatment. Key factors to consider include:
- The number of pregnancies as a potential risk factor for hearing loss
- The role of hormonal fluctuations and other physiological changes during pregnancy in the development of hearing loss
- The importance of regular hearing screenings for women who have had multiple pregnancies
- The potential protective effect of birth control pills on hearing loss.
