I have a question about this construction: (This is from NHK Easy news)

<https://www3.nhk.or.jp/news/easy/k10011625431000/k10011625431000.html>

> 寝る時間が足りないと、心の病気になったり、太りすぎたり、血圧が高くなったりする心配があります.

I want to know the use of "ーたり" in this sentence. Is this a conjugation of
some sort if you are listing items? Also, in 高くなったりする, why did it become たりする？
