Supposedly Epsom salt (technically is not salt) helps the body rid itself of excess fluid. Just beware it’s also used as a diuretic.

number one: cut your intake of salt. That is the worst offender.
drink more water.
use a B6 vitamin.
No hot dogs or processed foods
check all label for salt content.

Celery is a good diuretic, it will absorb excess liquid in your body and help expel it thru natural urination and bowl movements. I have lung cancer and celery keeps down my pleural effusion.

You might be consuming a lot of sodium. Try using less salt
