I didn’t respond to this because I didn’t want to freak you out. I am glad your results are normal.
I was sent to the nephrologist in 2003 because I cried. I was 220 lbs, eating 400 cal/day, because that was all I could eat, and gaining weight. I cried because my dr wasn’t goign to send me to a specialist b/c my test results were normal. He thought I was a big fat liar, I guess.
So I went to the nephrologist, and I was 225lbs. Some water pills and 10 weeks later, I was 80 lbs lighter (25 lbs the first week and another 25 lbs the next three weeks.). I am 5’2" and went from 225 to 145 in 10 weeks. My kidney function tests were totaly normal. The nephrologist said that there are people with less swelling whose kidney function was worse, as well as people worse off than me who have better kidney function. The test results are average and what is normal for one is not normal for another.
This is probably not your problem, just make sure you don’t let a problem go untreated or unrealized by your doctor. One thing that helps me with swelling is eating natural diuretics like cucumbers, celery and watermelon. Don’t overeat those, like probably no more than half a cucumber at a sitting, but they are all pretty low in carbs, too. Also, don’t be too far from a bathroom until you find how you respond. = )
Oh yeah, walking also helps with improving ciruclation and get rid of extra water.
