pseudopseudopthFor edema to occur shouldn't interstitial oncotic pressure be increased?(when proteins are there, they can pull the fluid)+12020-01-29T06:14:30Z
pseudopseudopthAnd when increased interstitial hydrostatic pressure is pressure, shouldn't it oppose the edema by pushing against it? +12020-01-29T06:15:37Z

pmofmalasiaYou don't necessarily need to have increased oncotic pressure, you're correct in that decreased oncotic pressure would act against causing edema but as long as the net change in forces still acts "for" edema it will still occur.
For example in this scenario, if the capillary hydrostatic pressure is greater than the change in interstitial hydrostatic and oncotic pressures.
Also, the change in interstital hydrostatic and oncotic pressures is a direct result of the edema in this scenario, so it's more like they're responsible for setting the new equilibrium - if they didn't counteract it, you'd never come to a point where the leakage of fluid stops.+2020-02-15T02:35:25Z
