Question about the usage of ーたり

Question

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？

Insights welcome

Don't we have an answer that explains grammar of たり? The linked post doesn't contain information, say, how to conjugate to it etc. — broccoli forest, Nov 15 '18 at 14:55
