Oily Urine


urine_sampleAlthough you may not always notice your urine, before flushing it down. It wouldn’t be uncommon or a bad idea to check it out. The consistency, odor,  and color of urine can be a good detector of many health conditions that are adverse. Dark urine could signal dehydration, and also kidney failure- where as lighter/clear urine means the condition of the body is overall healthy.

What you eat, drink, and how your urinary tract is running is signaled through many types of changes in the output of your urine. One of the inconsistencies that can be a sign of great distress, worry, or health concern is oily urine.

Oily urine can be an indicator of several things that are not too serious, and other health conditions that may need further investigation by a medical professional.

Oily Urine Causes

Urine is the fluid that is processed and expelled by the body’s urinary tract. It contains wastes that have been filtered out of the body by the kidneys. The yellow color in urine is derived by something known as urochrome (which is a small trace of blood.) But, as well as the small yellow pigment by urochrome- the yellow or very dark yellow urine. or brighter orange urine can indicate dehydration as well as many other things including blood in urine, infection, alcohol use, and even some foods in your diet or medications can make the urine change.

Here are just a few causes that may result in oily urine:


A slight trace of oil in the urine is normal. This oiliness originates when urine is held in the bladder for a while. Usually however- when this type of oily urine is also present along with a milky look- it could be known as chyle (fats and proteins) which is a condition which needs further look and treatment from a medical doctor.

Urine Ketones

If you are not eating regularly, have diabetes or sugar problems, or have recently changed your diet to lose weight- you may experience something known as ketosis. Ketosis occurs when the body can no longer utilize carbohydrates to expend into energy.  However, once  carb reserves are tapped out the body will automatically begin to metabolize fats in the body. This is where ketones are then spilled into the urine.


When urine turns dark yellow/ golden/ or tea colored. it could be a sign that you have not been taking enough water. Dehydration usually can occur during illness, fever, after athletic events, workouts, and also when you have recently lost water by way of diarrhea or sweating. Make sure to increase fluids when you notice your urine this way. If you have other signs and symptoms and you are not urinating often after increasing fluid intake- consult medical help.

Excessive Vitamins

Vitamins and supplements can cause oily urine to occur. This could mean that certain vitamins are in excess or that they are not being properly absorbed. Change your diet in this case and also consume supplements that are safe and used as directed.

Oily Urine and Other Types: Concerns and What to Do

Typically when urine is healthy or normal it will not give off a pungent scent or aroma. However, if you notice an ammonia-like odor from your urine it could mean that you may have kidney stones or an infection of the kidneys or urinary tract. Also, if you notice a smell that is sweet coming from your urine, then it could possibly mean that you have sugar problems or diabetes. In other cases strong smells given by passing urine could be caused by eating certain foods in diet such as asparagus.

Another thing that should be watched with caution when changes occur is the frequency of urination.  Commonly, individuals urinate from 6-8 times during the day (some more and some less.) However, other factors can influence this such as fluid intake, drinking tea, coffee, or alcoholic beverages. Urinary frequency can also be a sign of other conditions such as:

  • Bladder spasms as a result of overactive bladder
  • Stroke, Parkinson’s Disease
  • Kidney Infection or UTI (Urinary Tract Infection)
  • Insulin/Glucose issues caused by Diabetes
  • Prostate problems in men (Cancer, or enlarged prostate)
  • Inflamed bladder Brought on by a condition known as  (Interstitial cystitis)

Oily Urine: Bottom Line

The urinary tract and system built up of the kidneys, ureters, bladder, and urethra are just about one of the most vital systems existent in the body (especially when it comes to removing toxins, wastes, and excess fluids that the body needs to eliminate.

When the urinary system is having issues or problems occur, most often the color and consistency and odor of your urine can be a tell-tale sign. Do be concerned with sudden changes of urine that result in strong odors, dark colors, or red/pink urine which can indicate blood in urine cause by kidney stones and infections. Also if you have dark urine with a pungent smell accompanied by pelvic pain, fever, chills, frequent urination (no urination) and burning while urinating you should consult with a physician immediately to rule out infections and other conditions that are more serious in nature.


  1. It’s been several months since I noticed having oily urine, but it seems to be getting worse. Like another commenter mentioned, it’s only when left standing.
    I eat a very high carb diet, could probably lower my oil consumption though it really isn’t that high to begin with, so I can’t imagine it would be ketones. I highly doubt I’m diabetic, I’ve had a few blood tests this year for various reasons, some fasting and some not, nothing signaling diabetes or pre-diabetes. I stopped taking my multivitamin ages ago thinking that might be the reason, and even stopped consuming fortified foods recently to experiment and see if they’re causing it. It doesn’t smell, isn’t milky or frothy, and I’m always quite hydrated. (Though I do notice there’s significantly more of an oily appearance when I am dehydrated- but I can have some oil even if it’s nearly clear)
    I don’t understand what could be causing this. I don’t have insurance for the time being so I cannot see a professional for a while, I was hoping you had other advice or ideas of what I could be checking for or what it could be from.

    • It sounds as though you are aware of your oily urine and have attempted to make changes. Since your urine is oily, you would certainly gain benefit from reducing your oil consumption. At the very least, you will be able to determine if that is influencing your symptoms. If you abstain from consuming excessive oil and still have similar symptoms, then speak with a medical professional at that time. Best of luck, Brin!

  2. I’ve had a antibiotic resistant kidney infection and uti with severe burning since being bitten by my cat in May. I’ve had all testing and been in the hospital twice. I’m now doing a 24 urine collection for Wilson’s disease and noticed not only color but smell and oily urine. I’ve seen urologists and infectious disease Dr and awaiting a nephrologist the 25th.im at a loss with the pain from everything and now this…

    • You have spoken with medical professionals and specialists. You have taken tests and are awaiting results. Continue to monitor your symptoms at this time. Your medical professionals will be able to give you the answers that you seek. You may want to speak with an emergency medical professional at this time. Best of luck, Erica!

    • Stop vaping at this time and monitor your urine. It is possible that there is an influence that it related to your consumption of the pen. It is possible that your diet has caused the oily urine. When you have determined what the cause of the oily urine is, then make a decision about what you want for your future at that time. Best of luck, Mary!

  3. Hello,
    Since a week I notice gasoline like layer with very little froth in urine when left standing, not otherwise. I haven’t completely stopped carbs, but have reduced it. And since I am not eating much carb or protein I am using more unprocessed, cold pressed oils for my side dishes. Could that be a reason? My food doesn’t float in oil but one can see oil on plate.
    I am 27 year old female who gets frequently stressed out with job. Sleep isnt adequate.
    Please reply. Though it seems the post is an year old, I will try my luck out.

    • If you are noticing oil in your urine and consume excessive quantities of oil, then that is likely the reason for your oily urine. You may find benefit in reducing your consumption of oil. If you believe that you have oily urine due to reasons not associated with your oil consumption, then you should immediately speak with a medical professional. Best of luck, Reshma!

  4. Hi. Good day! Just yesterday, I’ve seen oily neon yellow in my urine. And 1week ago, I’ve started my detox and exercise since it’s beneficial to my PCOS. Is oily neon yellow a normal result with my detox and exercise? It also has an odor. Please advise

    • Speak with the medical professional that gave you the advice that you are following. If you did not speak with a medical professional before doing this diet, then immediately speak with a medical professional. Make an appointment with a doctor at this time. Best of luck, Aryb!

  5. I recently just had a UTI and I finished my 10 days of medication and I haven’t experienced any pain while urinating. It’s been over 2 months and 2 days ago I had sex and we used protection and I showered immediately. Then 1 day later I have been peeing oily neon yellow. It doesn’t burn and it’s not red.

    • Continue to monitor your experiences at this time. If you find that your painful and unpleasant symptoms arise again, then speak with a medical professional. If those symptoms do not arise, then it is possible that they have passed. You may find benefit in speaking with a medical professional about testing for sexually transmitted diseases. Have a great day, Jessel!

  6. I recently started taking glutathione 500mg supplements. This is the only “newbie” in my diet. Then i noticed recently that my urine turned oily. By any chance that the glutathione is causin my urine to be oily?

    • If you have decided to take supplements without speaking with a medical professional, then speak with one at this time. If you had spoken with a doctor before you began taking supplements, then they should have shared these potential consequences. Continue to monitor your experiences as you alter your diet and lifestyle. Best of luck, Kendra!

  7. Greetings. I observe that my urine have slight oil, beside that at the age of 25 i am a diabetic person now i am 26 years old. I observe the slight oil on my urine this month nov 2017. Before i observe this slight oil, i’ll start my regular exercise, diet, and taking mineral like fish oil and vitamins C and E this june 2017. Lastly lemon grass and korean ginseng is my tea and snack wll be chayote, taro, and sweet potato. Is it regular to have slight oil on my urine while im doing all things that i mention? Pls reply i need your answer.

    • If you find that you have oil in your urine and are aware that you are consuming excessive oil, then you may want to reduce your consumption of oil. Continue to monitor your experiences as you alter your consumption. If you decide to speak with a medical professional, then make an appointment. Best of luck, Bryle!

  8. Was good but need more information. I have fatty liver and been detoxing doing a carbs diet was a beer drinker but quitted 3 months ago . Want to know why sometimes I have oily urine taking amino acids to help clean my liver. Much appreciated

    • I would be hesitant about using a detox diet or supplements. Your body is naturally able to detoxify itself, and many of the commercial products put added strain on your liver. The best thing to do would be to eat a healthy diet and continue to abstain from alcohol. If you aren’t using products like beer or detox supplements that stress your liver, your body will naturally detoxify on its own.
