Low urine volume

[yurybx]

Hello everybody!
For the first time in 13 years of chronic fatigue syndrome, I measured the volume of my daily urine. And I was surprised when it turned out to be very low, given that in all indicators my kidneys look healthy. Urinalysis shows only slightly increased density, and a blood test for urea is normal. And, of course, I do not have kidney stones. In addition, I drink enough fluids every day. Specifically that day I drank about 1200 ml. and received only 410 ml. urine!
This worries me, since my grandmother died of anuria.
Has anyone watched low volumes of daily urine?

Check for leaks?

Maybe the missing amount is leaving as stools or sweat, making your urine volume appropriate for your body. Is your urine very dark? If not, then it's probably the appropriate amount of fluid to remove the waste molecules. It's something I'd mention to my doctor, but not panic about.

One of the things I feel that our education system fails at is educating us on what is normal for human bodies and what variations are healthy. I can understand the reluctance decades ago to discuss bodily functions, but today's society seems much more open about such things. I think it would have been useful to have a class explaining urine volume and stool size and consistency, and what variations mean, and when you should mention differences to your parents or doctor.

You could ask your doctor to check a complete blood count plus electrolytes.

But I drink more water in the first 20 minutes of being awake then you drink in an entire day. You drink only just over one liter of water in a 24 hour period ?

I see one very easy thing you could try here ;-)

I missed the low water input. I think I consume over double that in a day.

Is your urine very dark?

My morning urine is a bit darker than necessary. In the analysis results it is said that its color is amber (normally the color should be yellow). What does this mean?

I did a complete blood count and electrolyte analysis. The analysis showed a slightly increased number of red blood cells and a slightly shifted balance of leukocytes (more lymphocytes and basophils, fewer neutrophils). Other indicators are normal.

Now I understand that I drink a little liquid. And it's strange, because I always drink something when I'm thirsty. I mean, I always have drinking water at hand. And unfortunately, I find it hard to drink more because of the constant feeling of heaviness and overflow in the stomach. It seems that drunk water is long in the stomach and very slowly absorbed.
But even with such consumption of liquid, the volume of urine should be 67-75% of the liquid drunk. In my case it's 804-900 milliliters.

I do not know how to calculate fluid loss through stools and sweat. That day I had normal stools and I did not sweat especially, as the weather was not hot.

I don't know how to estimate water loss from other pathways either, but I expect it's higher than we might think. Just breath on a cold surface and see how much water condenses. Likewise, you could place a cold surface next to your skin for a few minutes to see how much water condenses. What feels like dry skin might transpire more water than you might guess.

As for urine colour, there are scales and explanations online. One says for amber: 'Your body isn't getting enough water. Drink some now.' Unless your urine is really dark and stays that way all day long, it's probably not a health issue. If you don't like drinking cold water, try hot and/or with additives (milk, soup stock, juice, etc).

There used to be a fad about drinking x amount of pure water a day. Coffee and tea somehow didn't count, but drinking a glass of pure water and eating a spoonful of coffee grounds or tea leaves would probably be okay. Irrational.

One thing to tie these together can be left renal vein occlusion or narrowing.

See if you fit for ANY of the symptoms of renal Nutcracker Syndrome. Nobody has every typical symptom and blood or protein in the urine may only be either microscopic or only found in a 24 hour urine test so not detected on a dip stick test.

Nutcracker Syndrome can cause autonomic dysfunction as well as extreme fatigue in some cases and can be misdiagnosed as CFS.

Indeed, I have some symptoms that may indicate a nutcracker syndrome: varicocele and cyst on the left kidney. But I did ultrasound test of the renal veins. According to the results, the diameter of my left renal vein is 7.9 mm (normal) with the observation that "before the aorta and at the point of confluence in the inferior vena cava, the left renal vein is not visualized due to flatulence." And the conclusion: "there is no data on the presence of the Nutcracker syndrome".
But I am alarmed by the fact that the test was done with a recumbent body. And, as far as I understand, it is in the standing position of the body that the superior mesenteric artery can become stretched and clamp the left renal vein. Are the results of the test reliable in the recumbent position of the body, do you think?

This is a problem I've had in the past, which I had to work on by getting used to sipping small quantities of liquid right through the day. I have a bottle with me wherever I go and whatever I'm doing, and once I got into the habit in my teens, I was able to keep up a good level of consumption. I no longer have the problem (no idea why it went away, but it disappeared maybe 20 years ago), but I still have the same sipping habit. When I did still have it, I found – counterintuitively – that carbonated drinks were less uncomfortable than still.

A Doppler U/S is only a screening test, and where the results can be dependant on the skill, knowledge and experience of the Technician doing the test, so no, I don't see this to be conclusive enough to rule out Nutcracker Syndrome (NCS) either.

A recumbent only test can be satisfactory if you have good visualisation of the whole vein but as you mention, it can involve either renal ptosis or visceroptosis and it needs to be done in the upright position to cover all aspects.

You would want to rule out NCS as a cause of varicocele regardless and not being able to visualise all of the renal vein too warrants doing a CTA or MRA scan. This is best done in both a supine and upright position too, something very hard to have done as an MRA but vascular imaging specialists can have a tiltable table for doing upright CT scans of leg veins which also suits for checking the renal vein.
