Why does my toilet run every few minutes and how can I fix it?

Your toilet may be running every few minutes due to a faulty flapper valve or a leak in the fill valve. To fix it, you can try adjusting the chain on the flapper valve or replacing the flapper valve altogether. You can also try adjusting the fill valve or replacing it if necessary. If these solutions do not work, it may be best to contact a plumber for further assistance.
