I had pretty severe swelling towards the end of my last pregnancy, but ironically none at all with my first two. Here are the steps I took that helped the most, sort of in order starting with the most helpful.
- cut out all salt. ALL salt. Not just some. Read labels on everything. Use other seasonings like garlic, oregano, olive oil for flavor. There is salt hidden in a lot of things, even unsuspicious things like bottled beverages. Beware of eating out. My worst swelling was sometimes after I ate out because a lot of food is way over-salted even if you can't necessarily taste it.
- Take a potassium supplement. The first day that I cut out salt and started taking a potassium supplement, I peed like 6-7 times that night, and the next day weighed in 6 pounds less than the day before, and I felt a ton better.
- Wear your support hose all the time, every hour of the day, not just a couple hours during the day.
- Eat high potassium foods, like potatoes and bananas. My favorite became a bake potato with garlic and seasoning.
- Swim or take a bath. The counter pressure of the water helps to promote circulation and shed excess water retention.
- Eat watermelon, also promotes shedding excess water retention.
- When you are in the kitchen, see if you can sit down at a table and prop your legs up on a chair while doing for prep like chopping, mixing, preparing lunches.
