More than 200 stones were removed from her body by doctors in an operation in China.
Guangji Hospital said that some of the eggs were as big as eggs after they removed them from her gallbladder and liver.
Surgeons told her that more than a decade of missing breakfast was behind the appearance of the stones that took six-and-a-half hours to remove.
Identified only as Ms Chen, 45, doctors said she often ate leftovers and did not have a regular eating pattern.
But last week the pain became unbearable and she had to have the gallstones removed.
Dr Quan Xuwei who operated on her said that if someone misses breakfast it stops their gallbladder from shrinking or expanding, leading to a build-up of bile.
That, he says, leads to high cholesterol and levels of calcium.
The NHS says that overweight women over the age of 40 are most likely to get gallstones.
They can be avoided by losing weight and a good diet.
British doctors disagree with Dr Xuwei’s assessment saying that people in China and Eastern Asia are more likely to have stones because of an increased rate of infection in the bile ducts.
Dr George Webster says the cause is often unclear and linking dietary habits to gallstones would be ‘pure speculation with no scientific evidence base to support it.’
