64-year-old Uncle Li often drinks tea and suffers from kidney stones . Are the two related?
64-year-old Uncle Li had a full-body examination at the end of last year and found that he had multiple stones in his right kidney and had hydronephrosis.
Originally, when he heard about kidney stones, he didn’t feel anything because he was diagnosed with kidney stones more than ten years ago. But it was nothing. The doctor told me to drink more water and just pay attention to my life.
But when he heard that his condition might affect kidney function and even cause infection, pus kidney and other conditions, he was afraid. He asked his son to take him to a large hospital for kidney-sparing stone removal surgery.
Fortunately, after treatment, Uncle Li's condition improved. But one thing bothered him, that is, his son asked him to give up the habit of drinking strong tea.
At the beginning of the diagnosis, my son kept saying: I told you not to drink so much strong tea without stopping. I told you that you would get kidney stones. Why are you so stubborn?
Uncle Li does not agree that drinking strong tea can cause kidney stones. He believes that after drinking tea for so many years, several people have developed kidney stones.
Neither of them recognized the other, and they quarreled with the doctor.
Uncle Li’s son told the doctor: My dad drinks tea every day, about two liters a day, and the drink is very strong. I didn't even dare to drink the tea he drank. I felt heart palpitations after drinking it. Doctor, tell me, is my dad’s condition caused by drinking strong tea?
Uncle Li retorted: TV health programs all talk about drinking tea to maintain health and drinking more water to nourish the kidneys. Why is it caused by drinking tea?
" The cause of strong tea cannot be ruled out, but the situation like yours is more complicated and there is often not just one reason. However, you can no longer drink strong tea and reduce the intake of tea," the doctor said said.
After listening to this, Uncle Li shook his head helplessly.
Coincidentally, according to a report from the political and legal channel of Changsha TV station, a 60-year-old man in Changsha was diagnosed with kidney stones because of a pot of strong tea every day.
