alptraum,
Thus your diagnosis will be the everpresent "IDIOPATHIC" HYPERTENSION...transtation, "we have NO CLUE"...I think the IDOIO is the same root as in the word IDIOT!!!
Medical profession hates straight talk- like maybe calling it CLUELESS HYPERTENSION might take them down a notch.
The ketones: "Few" probably means that you are on a diet and burning some fat...ketones are always thrown off. Lower carb diets throw off more ketones still! Diabetic ketosis is marked and MUCH higher than "few." Probably some latinate word meaning LOTS!...
Don't worry...It's pretty much the same diagnosis for everyone. A found cause is a rarity (those pressor [BP raising] tumors are quite uncommon.)
