Blood In Urine After Taking Aspirin or Vitamins
I’m 67 yo male. Never had a problem with either but about ten years ago I started taking one aspirin a day to prevent heart attacks. After a month I had blood (first time ever) in my urine and after days of online research I read it could be caused by the aspirin. At the time I also used to take two to four Advils a day regularly for lower back pain from an old lifting injury. However I had developed acute back pain on my lower left side and it looked swollen. I stopped taking aspirin and Advils and the blood in urine and left side back pain disappeared. I also stopped drinking coffee and colas because I was drinking it too much. From time to time the bloody urine would return if I started drinking colas again and would last sometimes only one day. A few months ago, after not drinking sodas for a month I drank one can and my next pee was dark brown for one day, then went back to normal.A couple of weeks ago I decided to take some vitamin C for extra Covid protection and the next day I was peeing blood with big clots so much it looked like I had sliced a vein. I stopped taking the C and in a few days my urine was normal again.The only time I’ve ever experienced bloody urine was in correlation to taking aspirin, vitamin C or drinking colas and this started about ten years ago after I started taking the aspirin.I’d like to understand, without taking a lot of expensive tests, which organ is bleeding and what’s going on? I don’t feel it’s an illness but seemingly related to the aspirin, etc.Any help appreciated. Thanks.

I would go and see a urologist based if it were based upon my experience. I had experienced seeing blood in urine when I was taking a baby aspirin to reduce incidents of heart attack. The test for infection was negative but when I had third time seeing blood urine, I went to ER and luckily, the ER doctor after confirming the blood in urine arranged CT scan with contrast. The CT scan showed a 2cmx1cm mass. The radiologist expressed his concern about the mass. I was wishing that the mass was just clot of my blood. A week later, the urologist did cystoscopy and showed me a coral like mass and told me that I had a bladder cancer. I am aware now that one of hall marks of cancer is its ability to have our body build new blood vessels to feed oxygen and nutrition to enable cancer cells to divide constantly. But because those new blood vessels are fragile, the constriction and the expansion of the bladder to store urine and void it, those blood vessels tend to break, causing bleeding. At that time, I thought perhaps, taking baby aspirin as blood thinner to reduce the risk of heart attack might have contributed in causing bleeding. I will never know. But, in anyway, finding that the mass was a tumor was shock to me but I am glad that bleeding had happened and I was able to see blood in urine and followed though the processes.

Nice Guy,
It is my fifth year 5 with bladder and kidney cancer. Both bleed. Based on my experiences;First you need to determine if it is blood you see. Events of 10 years ago offer only suggestions of prior history.
Dipstick urine tests are cheap. Buy the test at a drug store. It will tell you if your next “bleed” is likely to blood or discolored urine; these are screening tests, not diagnostic tests.
Vitamin C can color urine to orangish hues and be mistaken for blood. Cola can be an irritant and promote bleeding. NSAIDS, including aspirin can promote bleeding. Having used any of these can be suspicious but not diagnostic of a urinary bleed until a office urinalysis proves blood.
Urinary bleeding is often below the level of detection by eye. An office urine test, spun down and examined by microscope, is needed for a real answer as to blood.
WHICH ORGAN ? Anyone’s guess without medical tests. IF there is blood.
The concern about blood in the urine is that CAN BE an early sign of bladder cancer. A tiny fraction of urinary bleeds are due to urinary cancer – but ruling out that cancer early is really important,

Simple answer is, you know as much as we do. None of us are doctors. Anything I might post is simply a guess.
As I already posted this could be coming from your stomach, bladder, kidneys. You could have an intestinal issue. Often, there is no known reason for the bleeding. It sounds like you have already figured the reason out? Have a great day!

“why are you on a bladder cancer board?”
Because I have questions and I’m looking for a place to have a discussion and seeing as how the bladder could be involved I posted my question here for discussion.
This is a forum … a place for discussion.
It was 100% predictable that the overbearing response would be go to a doctor.
But I didn’t ask “what should I do’, I asked which organ would start and stop bleeding after ingesting cola or vitamin c ?
Aspirin often does cause bleeding. It can be from your stomach, bladder, kidneys etc.
As Sara Anne wrote, bleeding of any type does need to be checked out. As you said, stopping some of the OTC drugs may be a simple cure. At the same time as a bypass survivor, 2 bad hernias one that was close to strangulation, bladder cancer, a melanoma found some 6 years ago I have learned checking things out before things got worse has saved my life. Plus, my quality of life and general health has only gotten better. Otherwise (please do not take this the wrong way), why are you on a bladder cancer board? Bleeding can have 100+ causes of which many may never be found.

” in many cases, a cause is never found.”
Well, I can tell you what’s causing it and I can make it start and stop. So, it’s not cancer,
I’m wondering which organ is bleeding and how/why the cola, aspirin and vitamin c is causing it.
And I’m not “fooling around”. That’s a rather rude answer.
Going to a doctor is like going to a dealership to get your car problem diagnosed.
There’s a lot of manipulation to do tests and checks to cover all possibilities.The reality of it is going to a doctor is the last, rather than first, resort.
Especially since the normal person can’t understand medical costs and billing and the hospitals and insurance are in bed together.With the exorbitant cost of health care and the ripping off of the public, I’d rather try to understand better what I’m dealing with before I subject myself to going carte blanche for a lot of unneeded tests and visits.
The only person who can make a diagnosis for you is a qualified physician. Anything else is just what you have now….guesses. Since the appearance of blood in the urine can be due to a lot of things, including bladder and kidney cancer with no other symptoms, you really need to have this checked out. Also, in many cases, a cause is never found.
Please don’t fool around with this!!
