Hey, I m 20, a female, I m 5 4 and approximately 120 pounds. I was diagnosed with Gastroparesis when i was 16, I m Hypoglycemic, and have peripheral neuropathy. (my gastroparesis is cause by damage to my vague nerve) the past few days I have been unable to pass stool, and when i need to go its just a white foam like substance.? Any suggestions as to what it may be, and the seriousness of it? I seem to get colitis quite often, could that be all it is? and if so how urgent is it that i have it checked out? ( i am not on any medications) Thanks in advance!
