Can a person die from multiple sclerosis? Most people with MS do not die from it, although some studies suggest it shortens life expectancy by six or seven years. What can kill people with MS are complications of the disease, including lung infections (pneumonia) and sepsis, a life-threatening response to infection.

How do you die from multiple sclerosis?

A diagnosis of MS is not a death sentence. Multiple sclerosis is not fatal, except in very rare circumstances. During advanced stages of disease progression, it is possible to die from complications related to MS (such as infections or pneumonia). However, that is far from common.

How likely is it to die from MS?

It is rare, although not impossible, for someone to die from MS itself. However, some people with MS develop disabilities that make them very vulnerable to serious complications which can lead to death.
