Why is my toilet backing up and how can I fix it?

Your toilet may be backing up due to a clog in the pipes. This can happen from flushing items that shouldn't be flushed, such as paper towels or sanitary products. To fix it, you can try using a plunger to dislodge the clog. If that doesn't work, you may need to use a Plumbing snake or call a professional plumber for help.
