Could dystonia impact pregnancy in a 29-year-old?

Question

Hi doctor,

My friend is 29 and has generalized dystonia. It affects her neck, shoulders, and occasionally her arms. She is considering IVF, as she is unsure how her condition and the medications she is on, including muscle relaxants, might affect natural conception.

Could dystonia or its treatment impact her ability to carry a pregnancy safely?
Is vaginal delivery feasible for someone with muscle coordination issues, or would a planned C-section be recommended?
Are there hormonal changes during menstruation or pregnancy that may exacerbate dystonia symptoms?
She is also curious if the Botox injections she receives will have to be stopped during pregnancy or breastfeeding.
Are there any special precautions she should take if she opts for a non-hormonal IUD?

Thanks.

Hi,

Welcome to icliniq.com.

I can understand your concern.

Generalized dystonia can certainly pose unique challenges during pregnancy, but many women with this condition have had successful pregnancies with proper care. The dystonia itself does not typically affect fertility, but some muscle relaxants and anticholinergic medications may impact ovulation or embryo implantation, and certain drugs may not be safe during pregnancy, so a preconception medication review with her neurologist is essential. IVF (in vitro fertilization) is an option if natural conception proves difficult.

During pregnancy, hormonal fluctuations, especially estrogen and progesterone, can potentially worsen or improve dystonia symptoms, and some women notice increased spasms around menstruation or in later trimesters.

Regarding delivery, a vaginal birth is not automatically ruled out; it depends on how her dystonia affects her trunk and limbs during labor. If dystonic episodes are severe or unpredictable, a planned C-section might be considered for safety. As for Botox, it is generally avoided during pregnancy and breastfeeding due to limited safety data, although some neurologists may consider it on a case-by-case basis if the benefits outweigh the risks.

A non-hormonal IUD, like the copper IUD (intrauterine device), is typically safe, but insertion might be more difficult in women with pelvic or core muscle involvement, so having it placed by a provider experienced with neuromuscular conditions is advised.

I hope this information will help you.

Thanks.
