I hesitate to post #medical disinformation but at this point I think it's clear

I have been dissolving #kidneystones with crystalized lemons

In 2023, I had to have two stones removed surgically.

For Christmas 2024, I got big boxes of "True Lemon" packets (lemon, lime and orange) as flavors to drink more warer. But I've always loved sour things so I was just tossing back packets like candy.

Jan/Feb 2025 I started noticing stinging while urinating. By spring, I had captured a ~1mm stone.

Still not realizing the connection, I came up with a homemade lemon ice #recipe that I would then add lemon packets to. I started eating this daily as a low-cal, high-flavor treat. (Each serving of the ice is ~1 lemon worth of lemon oil and juice, but I also dump....20-30?...packets on a serving. If the marketing is to be believed, this is equivalent to several lemons per day. I LOVE sour.)

To be clear, I'm also still drinking vast amounts of water.

Over the summer I started collecting more and more stones. Every week or two there'd be a day where I'd get say 5 ~1mm stones plus various tiny bits over the course of a couple hours, exactly as if a larger stone broke up and came out as pieces. (Also some other phenomenology I won't get into here.) Mostly there's no pain associated with this but that's not to say I feel nothing.

Once I noticed the connection, I experimented. No lemon for a week or two -> stones stop. Back on lemon -> stones resume. I've done that cycle a few times now under different conditions.

Clear, detailed info on kidney stones is hard to find because there are so many different chemistries and causes. And very few will go so far as to say you can *dissolve* stones.

But also, very few can be taking in as much citric acid as I am.

But here's the deal: *citric* acid helps prevent and may also dissolve (some) kidney stones. But *ascorbic* acid can cause them.

So MAYBE I'm *causing* tiny stones to grow rapidly, passing them and calling that victory.

I would love to get some X-rays to really know.

@davidr get some pH paper and check your urine pH.
Citric acid should be broken down in metabolism, before making your urine acid enough to dissolve stones.

@dtl Citric acid doesn't make urine acidic. It makes it alkaline. This is already well established.

What they are less willing to go out on a limb on is *dissolving*. If they say anything it's "may help".

I have pH paper, but without definitions of "more alkaline" or what level a kidney wants it's not very informative.

@davidr Yes, causing vs dissolving was the first question I had.
Aren't you monitoring the condition, since it caused the operation?

@triffen I mentioned most of this tale to my GP a few months ago. He mainly wanted to know if there was any blood (no) and lost interest.

When I pressed, he said he thought I was probably breaking them up. (i.e. the stones are conglomerates in the geologic sense and the citric is dissolving connective bits)

On that same visit I had a blood test (not specifically for this) and I've also recently taken a UTI test.

But they aren't very interested in kidney stones unless you are bleeding, vomiting or fainting. Anything short of that is "drink water and maybe avoid oxalates"

@davidr Meh level of healthcare :(
@triffen I normally really like him but yeah, I felt like he dropped the ball here. Tho to be fair, it's probably more of a science puzzle than a medical issue that needs treating
@davidr Well, they should be preventing more stones, saving you pain and government's money (if you are somewhere with State healthcare).
Ours tend to go in the opposite direction, torturing patients with all the tests and appointments if they don't have anything more serious to treat. They are like an overactive immune system ;)

@triffen No state healthcare but pretty good private insurance, considering.

You are right, I should ask for a better diagnostic test for the record if nothing else. It would also clear up a variable that's clouding my own "research"
