Why epinephrine does not cause GFR to increase?

[chasan2]

Does anyone know why epi does not cause GFR to increase?
It seems contradictory to me because whenever I am excited like before the exam, I need to use the restroom to get pee.
If epinephrine is not the cause of high GFR, what causes human to have to urge to pee?

The one cause human to pee is a ADH hormon not GFR. Increasing or decreasing GFR is based on the osmotic balance in the body. GFR mainly function is filtration of the human body fluids.

Ephinephrine effect is on the alpha and beta 1-2. The effect on beta 2 is the mainly effect on the intestine and kidney.

Caffein and alcohol reduced the ADH hormon...that the reason you keep want to stay in the rest room after you drink it. I wish it helps you.
