Do diabetics have sugary interstitial fluid?

  1. Feb 20, 2015 #1
    So my understanding is that capillaries leak out their blood plasma containing sugar and other nutrients insulin (when sugar present)near body cells, and this is what comprises interstitial fluid.
    But what if no insulin is present (Type 1 diabetes) or insulin creates no response (Type 2 diabetes)?
    Does the interstitial fluid just remain sugary since the glucose can't enter the cells?
    My understanding is that capillaries only use diffusion as transport, so they can't reabsorb glucose from the interstitial fluid, right?
    When someone has a "high blood sugar," does this also mean that interstitial fluid sugar concentration is also high...?

    Thanks SO much! :)
    I have been researching this forever but can't find a clear answer! #=_=

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    Continues Glucose Monitors (CGM) used in people with diabetes to track their blood glucose levels every 5 minutes or so can be used to check their blood glucose from the interstitial fluid, obviously there is a time-lag between the blood that is directly from plasma and the interstitial fluid, of about 10 minutes. So to answer the question, yes interstitial fluid would contain high glucose if a person is diabetic and didn't main their glucose levels with insulin (Mainly T1) and (Oral Meds T2).

    Blood flow rich in glucose from capillaries would leak into the interstitial fluid, when their glucose plasma is high, it will also mean their interstitial fluid is high in glucose too.
