Katie Thurston‘s cancer treatment has sent her body into menopause … one of the many symptoms she’s dealing with while fighting stage 4 breast cancer.

The former reality television star shared a video to social media … telling her fans she’s now experiencing hot flashes because her cancer treatment has forced her into menopause.

For those who don’t know, chemotherapy is one of a few ways women can go through early menopause … so, not totally shocking this is happening to Katie while she’s dealing with her severe form of cancer.

As we told you … Thurston announced her breast cancer diagnosis back in February, shortly after she became engaged to comedian Jeff Arcuri. The two were traveling the world together — but had to cut the whole experience short so she could begin treatment.

Katie said the diagnosis sent her through a gauntlet of emotions … before she sat down and started looking for other women like her who have been through similar difficulties.
