Can kidney stones cause anemia?

It took a while but the pain I was having was finally diagnosed as a kidney stone and I have another symptomatic one in the other kidney. But I wonder if kidney stones cause anemia because I suddenly became anemic just over a year ago and we have not been able to find a cause. Although I had occult blood in my urine due to the stone, it was not a lot.

I was wondering if anyone else has experienced this too or if anyone might know if stones can cause anemia?

Hello and hope you are doing well.

Constantly losing blood in the urine can cause anemia, even if it is occult. Stones can sometimes cause kidney failure. Chronic kidney failure can cause anemia. This is due to a decreased secretion of the hormone erythropoietin. This hormone is a necessary stimulus for normal bone marrow to produce red blood cells. Just cautioning you.

Hope this helped and do keep us posted.

Thanks for your reply. I've had one kidney stone removed via lithotripsy and the existing one is still small. My erythropoietin levels have always been fine and all other blood labs indicate iron deficiency anemia. I think I'll go ask the doc to have my iron tested again to see if removing the stone has helped with my iron levels. I take a small amount of ferrous sulfate but it has kept me hovering just above the normal levels. I'm glad to know that kidney stones could be a possibility though. I hate not knowing why this happened so suddenly.

Having a kidney stone in the urinary tract will not cause anemia.

If the stone is moving and tearing the linings of the urinary tract that causes bleeding then depending on the loss of blood and for how long the blood loss goes on for can cause anemia.

As you have had kidney stones and have been feeling unwell, your food intake was probably not the same as when you were well.  When I had my stone I was not able to eat and lost a lot of weight.  I had no appetite at all.

The anemia has more than likely come about you not eating well becasue of your kidney problem.  Your doctor should prescribe you with a course of iron.  Make sure you do not drink tea when taking the iron tablets at the same time, becasue it hinders its absorbtion.

Once yu have had stones, you will be prone to getting them again.  Hope you had yours analysed so you know what the composition was.  

I was told to avoid dairy products becasue mine was a calcium stone.

Always drink plenty of water.  2-3 litres being the norm.

Thanks for your comment. I am inclined to think that the stone was causing the anemia because it started shortly after I started having the pains. I didn't have typical kidney stone symptoms so it took a while before it was diagnosed and actually taken care of.

However, the pain did not stop me from eating. I had no problem eating! I did have trouble with physical activity though and actually gained weight.

I have been taking iron for the anemia and it has kept me just above normal levels, barely above.

My urologist explained that not getting enough calcium actually causes excess calcium in your urine and that I should actually try to consume more. It made sense when they said it but I don't know the specifics on that. My stone was made of calcium oxalate and I was advised to stay away from foods with lots of oxalate, consume more calcium (not supplements), consider taking magnesium and of course, drink lots of water with real lemon juice in it.

I hope all these changes keep my kidneys from making stones. And I send the same wishes to all those other stoners out there.

Sounds like the theory of eating calcium foods has changed since I had my stone.

My stone was a calcium oxalate one and I was told to avoid dairy produce, rhubarb, strawberries and beetroot.  I do not particularly like cheese, so I don't have a problem with that.  I do eat and drink live yogurt now though.

I'm not 100% , but I am sure that I have read that to help absorb calcium we also need to have vitamin D.

As with iron, to help absorbtion of this mineral, we require folic acid (found in cerials and brown bread).

Interesting. I have been told I'm anemic for some time now but did not realize I had kidney stones until a couple years ago when I was struck by a painful one that put me in the emergency room.
I wonder if there is a correlation but my doctor's believe the anemia is due to heavy menstrual bleeding and kidney stones are due to not enough fluids. When I had my original stone, I may not have had enough fluids but generally I drink quite a bit of water throughout the day. Last night I got another painful stone but more mild than before, the only thing I can contribute it to is an increase in nut intake (oxlates) and specifically I decided to try drinking cashew milk.
My doctor also gave the same advice about actually needing to consume calcium to avoid the kidney stones. I was also told to drink orange juice with the iron because it helps with the absorption. Hope that helps.

Kidney stones can be or are caused by too much calcium and lack of Magnesium> Since you are researching. I'd like to direct you to Search Magnesium and kidney stones. This is one sign of lack of Mg, also included is anxiety and hundreds more., Dr Carolyn Dean's book is amazing. "The Magnesium Miracle.". It will help you understand your symptoms and have instructions what to take and how much,and you will be amazed at what problems lack of Mg can cause. Youtube is another good source for searching on Magnesium, several clinicians have recorded reports and findings. Also make sure to take note of oral magnesium replacement and transdermal Mg at the same time. Oral Mg takes 6 to 12 months before it would build up enough in your system, while transdermal Mg will work instantly but you have to spray it on frequently. I got used to it. I use both but oral replacement is much simpler eventually. I have put my whole household, friends and family on Mg supplementation. You probably will end up doing the same once you do your research. Its best to get the books too. They have further info that won't be on line nor on Youtube.  
The other book is "Transdermal Magnesium" by Dr. Mark Sircus... with instructions on how to use it , He is also on Youtube.
Good health and good luck.
PS cooking in an iron cast skillet will add iron to your regular foods. Its one safe way to build up your iron stores.

The first symptoms that I had was pins and needles in my feet.  This baffled the doctors as what the cause was and I was first of all treated for Vitamin B complex deficiency and then later on with antidepressants.  Eventually sent for xrays and other tests.

What I did do was to seek alternative help by having reflexology and aromatherapy sessions and was told that I had a kidney problem - even before the doctors knew.

There are 4 main different types of kidney stones:-

calcium oxalate

The rarest form of kidney stones is Cystine stones.  Cystinuria is an inherited condition that affects the amount of acid that is passed in the urine.  

Struvite stones are caused by recurrent kidney infections.

Uric stones are caused when there is too much uric acid in the urine with rheumatic conditions like gout.

Calcium oxalate stones can from with too much protein in the diet, too much calcium and Vitamin D and through dehydration.

Being anaemic will not cause kidney stones.  Anaemia is lack of red corpuscles in the blood that carry oxygen around the body.  This will make you feel very tired.

I figured I'd come back and continue on with my story.

About a month after I had my lithotripsy to remove my big, painful stone that was trying to get out of my kidney, I was able to stop taking my iron. I have enjoyed several months of energy without iron. Two months after that, my iron levels actually started climbing!!

At the 2 week follow-up post-lithotripsy, my stone was completely gone. At the 6 month follow-up, I had already grown another one to almost the same size at the first one. I have had two episodes of severe kidney and flank pain. Yikes! I then started feeling sluggish again. I had my urine and blood tested. Guess what? Low iron and blood in the urine. Back to the iron pills.

So, I can safely say that kidney stones can cause anemia. At least for me they do.

I also am very interested in the magnesium subject! I started taking it per the urologist recomendation and my feet stopped curling up at night! No more of those terrible cramps! I also makes me regular. I didn't know it took so long to work its magic but I am nearing

oops! hit enter by mistake

... the six month mark on taking it.I think my arthritis feels better too! What is discouraging is that there are already more stones in my kidneys and they are causing pain. I have not stopped drinking water and put lemon juice in it. I have avoided over indulging on oxalate foods and I am better about my calcium intake and take it easy on the vitamin D (I was taking so much we thought that might be causing the stones). As my urologist said, as women age, they are more prone to stones. NOT FAIR!

I goggled, can to much iron cause kidney stones ,  I was curious because I have always been slightly anemic and was taking vitamin's with iron in them.  I went for a physical and found out my iron serum level was to high and can be "Hemochromatosis" This is where your body stores iron in your liver, brain, other organs and causes all kinds of issues,  arthritis , thyroid , gout, Alzheimer's .  Please be careful of iron, you could test low and be anemic yet your iron serum level could be high.  With my first stone I had goggled "kidney stones" nine years ago and "hemochromatosis" was highlighted in bottom of paragraph.  I have learned so much from everyone's comments, keep sharing.  I'm waiting for my second procedure, l have large stone in kidney and smaller on stuck before bladder.  

I've drank distilled water since  early twenties and did not get 1st stone until 40.  I'm now 53, they run in my family.  I will get them tested this time to find out what's causing them because I like everything that causes them. My first stone was not painful but I did have blood in urine.  It did cause a lot of stomach issues.  All of which cleared up after it was removed.  This stone has been very pain full.  I used to see little gray stones in toilet all the time before I knew I had them.  Now I wish I had checked them out.  

p.s. I do take magnesium and vitamin d

Hi,  I recently made my first post here about what appears to be blood in my urine which I am assuming is related to kidney stones in some way.  I will be making the appointment to see the doc asap but was more worried because this time around, I have not had any pain really, just the odd urine color. I noticed you mentioned your first stone was not painful, but you did have blood in urine. Anyway, Id rather the blood be attributed to kidney stones as apposed to something more dangerous and in lieu of seeing a doctor its good to know Im not the only one.
