SUBSTITUTION: tips, tricks and guidelines

[FakeBoobsRule]

My head is hurting from the poor information on metabolic disorders, diet, decomp/decay of urine, and substitution. It is one thing to find info on the internet but it takes a little more to understand it properly. I don't know where to start the presence of glucose in the urine or the presence of fructose in the urine.

you can definitely have fructose in your urine. it's called fructosuria. both are in your urine in diabetes and with heavy sugar loads. it's a slower digesting sugar than glucose.

I will start with fructose and fructosuria. Fructosuria is the presence of fructose in the urine and it is NOT normal. It is NOT caused by eating a meal heavy in sugar or fructose. It is caused by a metabolic disorder where the body lacks the enzyme fructokinase. You shouldn't have fructose pumping through the proximal renal tubules of the kidneys. The kidneys are not supposed to reabsorb fructose because the kidneys should never see fructose and the problem is the lack of enzyme and not in the kidneys. Let's review this again. You eat something containing fructose. Fructose has to be converted to glucose or glycogen before your body can use it. The kidneys should never be exposed to fructose because it is broken down first by fructokinase. Your kidneys do not "know" how to reabsorb fructose because that is not a normal job of the kidneys because fructose should be converted to glucose or glycogen. So if your body lacks fructokinase, this is the only way fructose can end up in the urine, not from eating a bunch of fructose.

here's the article to support that since it seems every starts from a priori of zero here:

Like I said earlier, this article is useless.

you're right about the second part. i never contested that--if you read my posts, i agreed fully with whoever first made that point. its a violation of HIPAA which is the current legal standard of medical confidentiality in the united states. i made this point a long while ago. actually i think you made it first if my memory's right. but i agreed with you.

Again I have repeated this before, HIPAA deals with confidentiality and I am almost positive it is the Drug Free Work Place Act of 1988 that prevents gender testing. Really this is becoming a mute point because it is a fact that by law they cannot test fluid/tissue samples for things other than drugs. Does it really matter which act or law covers it.

also, both glucose and fructose can end up in the urine in ANYONE whose kidneys can't reabsorb sugars.

Wrong. I tackled the fructose in the urine, soon I will discuss glucose in urine and meals.

it's not just diabetes, despite what you might be initially taught in school.

I never said diabetes is the only cause of glucose in the urine. I said that was the classic sign of diabetes and there is a difference. It is like saying all squares are rectangles but not all rectangles are squares. Diabetics often times have glucose in the urine if it is uncontrolled but glucose in the urine doesn't always mean diabetes. I am fully aware the differential diagnosis includes every thing from Cushing's to acute renal failure.

the proximal tubules of your kidneys reabsorb sugar. if they are overloaded (ie from a sugar rich meal), you will have sugar in your urine. although it can be a sign of diabetes, that's because the diabetes disease process damages your kidneys reabsorptive capabilties.

Now we are at the heart of the problem. You have incorrectely identified cause and effect in several ways. Normal blood sugar should be between 80-110 mg/dl, some say 120. I go with current guidelines and use 80-110mg/dl. After a meal the blood sugar may spike up closer to 200 mg/dl in normal people. This peak may last around 2 hours or less and your body deals with this by producing more insulin from the pancrease. If you are normal your kidneys should easliy handle this 99% of the time. Your kidneys will reabsorb glucose and no glucose will be deposited in the urine. Even during this 2 hour time period your kidneys should be able to handle this. This is the normal process. The abnormal process in a diabetic (other disease processes withstanding) is that the blood sugar level rises long enough or high enough that it overwhelmes the kidneys and some glucose may end up in urine. This can be complicated by poor patient compliance as far as diet and insulin regimen. It doesn't start off with damaged kidneys leading to decreased efficiency. However, if this happens enough times there is kidney damage and it becomes easier to overwhelm them, a vicious cycle. So let's review:

Glucose in the urine in a diabetic is caused by blood sugar levels high enoug/long enough that the kidneys can't reabsorb all the glucose.

anything that slows your kidneys down, or someone with genetically slower kidneys, can have sugar in their urine.

This is so vague and and out there I am just going to say let's imagine it was never said.

here is a link that elains it with more formal language:

Renal Glucosuria: Tubular and Cystic Kidney Disorders: Merck Manual Home Edition

You should re read your own link please. I think you are missing some things. For instance, when it says "very high blood sugar levels" that doesn't mean 200 after a meal. They are talking about 350, 400, 500 mg/dl which doesn't just happen from eating sugar unless there is a disease state present.

i'm not sure if anyone cares--i'm just saying don't leave urine on the shelf too long. if you're someone dropping sugar in your urine after having a lot of junk food, the urine will not remain sterile for long.

Again, normally there is no glucose in urine even after a sugar filled meal unless you have a disease state and the most common disease state for this to occur is diabetes.

What causes urine to decay/decompose is the breakdown of urea yielding ammonia which raises the pH of the urine beyond the accepted range. It is not fermentation by bacteria.

I'm sure I missed something but that is because I am really tired from having to correct bad information but this is pretty damn close.

Despite what you said this isn't about playing in the same sandbox. What this is about is people come to the drug testing forum usually in a panic. They have a drug test coming up for a job, probation, maybe child custody case. Many times they are so upset and worried they don't read all the information in a post or posts. Many people give incorrect advice here and eventually someone will provide the correct info in the thread further down or in another thread but some don't read that far. I am just trying to help people and this isn't anything personal. I have only grown pot once so you wouldn't find me in the growing forums giving advice and if I did I would hope someone would correct me when I said something wrong.
