Thanks for that image. That gives some idea about what volume of space they can occupy, and hence how many there might be.
It is still unclear at what rate they form, and if you stop seeing them in flushes, how long you will be clear for (assuming a decent diet)...
Are the lumps continuously pushing forward and out of the body, as a normal course? Or do they dissolve and get absorbed back in the body?
One of the lumps I had passed was 1 inch in diameter. It did appear to be a number of small lumps that stuck to each other, so I don't know if they just joined together at the last minute, or were that way for a long time in the liver/GB.
