"This is a definite myth," says Matthew McCoyd, MD, a neurologist and MS specialist at Loyola University Medical Center near Chicago.
"In the pregnancy year (9 months of pregnancy plus 3 months postpartum), there is no change in the relapse rate," he says. "And there does not appear to be any long-term impact on disability."
Many studies over the past 40 years suggest that pregnancy can actually reduce the number of MS flares, especially in the second and third trimesters.
"While pregnancy is obviously an intensely personal decision, MS should not play a significant role in the decision," he says.
MS treatment options do change during pregnancy, though. Talk to your doctor if you're considering becoming pregnant.
Myth: All people with MS will need a wheelchair.
Most people with MS don't become severely physically disabled. According to the National Multiple Sclerosis Society, two-thirds remain able to walk.
But many will need a walking aid such as a cane, crutches, or a walker.
"Some people who are able to walk choose to use a motorized scooter over long distances so that they still have energy left to enjoy an event or activity once they get there," says Rosalind Kalb, PhD. Kalb is vice president of clinical care at the National Multiple Sclerosis Society.
It's true that you many need to think differently about how you move around, but you don't need to stop moving. Staying mobile lets you keep doing the things that make life meaningful and enjoyable.
