urine in protein vs kidney function

https://www.youtube.com/live/-eaTQkaO09o?feature=share

passing 200 to 300 mg of albumin per day in the urine is a sign of
trouble in the future - both kidney trouble and cardiovascular trouble

if I understood correctly - albumin is a large molecule and it has a
negative charge - it contains 60,000 atomic units - other proteins
typically contain 20,000 atomic units - albumin can plug up some of
the vessels in the kidney - this causes kidney cells to malfunction -
which causes some albumin to spill into the urine - apparently this is
not normal

this explains how albumin (a protein) gets into your urine

the next question is - how did the excess albumin get into the
bloodstream? - we dont know if the doc explained that - however - near
the end of the video the doc said you can limit your protein intake to
40 to 60 grams per day to reduce the load on your kidneys

if you want to be 100% sure about what the doctor said - feel free to
watch the video and take notes

note - the doc is retired - he was a kidney doctor for 40 years - a
nephrologist - he provided medical cures for patients - urologists
provide surgical cures for patients - that was his definition of the
difference between a nephrologist and a urologist - although the
common definitions might be - nephrologist works on kidneys - and
urologist works on bladders and urethras - though there probably is
some overlap there
