The Jubilee Party MP was elected while in hospital with confirmed reports indicating that she was receiving treatment for cancer since 2014.
At the time of her passing, Ms Kipchoim had been placed under palliative care at the Nairobi Hospital.
The female MP was a widow, a situation that some of her political opponents used to malign her name.
"It hit me by surprise as my opponents used various forums to fight me, claiming I am a 'bad omen' to the community because I am a widow," she conveyed after winning the seat in 2017.
The MP had been bed-ridden for most of the 2017 election year and was not able to conduct campaigns nor cast her vote for the Jubilee primaries and the MP election.
"My political journey has not been easy, amid illness. This is God's making. He makes things work for our good. I am thankful to the electorate for making me proud once more," she said at the time of her victory.
She was passionate about peace efforts for her constituents who have experienced cross-border clashes through the years.
"My joy is to see my people get back to their homes and be able to take their children to school without fear," she pledged in 2017.
