Whole body swelling especially hands, face, feet, during week 22 pregnancy, bp is 115/70, no proteins in urine, urine pH is 7, why swelling? Any diuretic?

Edema in pregnancy. Following your last question, if your swelling is not acute in onset it may just be a normal process in pregnancy, there are a few things you can do to reduce it: avoid caffeine, limit salt intake, rest with your legs elevated, use support stockings, avoid being outdoors when it's hot, consume potassium containing foods like banana and orange. Good luck.
