Shaved ice lands man with kidney failure on dialysis, doctor warns of 4 dangers

A man's craving for shaved ice nearly cost him his life, highlighting the hidden dangers of seemingly innocuous treats for individuals with compromised kidney function. The 65-year-old, who had stage 4 chronic kidney failure, experienced severe abdominal pain, vomiting, and diarrhea after consuming a bowl of shaved ice with traditional toppings like red beans, peanuts, and taro balls.

Ice shop hygiene conditions vary, and ice cubes and toppings can easily breed bacteria. Once acute gastroenteritis and persistent diarrhea occur, dehydration will cause kidney function to plummet.

His condition rapidly deteriorated due to severe dehydration, leading to acute kidney injury and a dangerous spike in uremic toxins. Doctors at Hong Yong-xiang Clinic intervened with emergency dialysis to save his life. The incident underscores the critical need for kidney patients to be vigilant about food safety and ingredient choices.

Dr. Hong Yong-xiang, a nephrologist, explained that while kidney patients aren't entirely forbidden from eating ice, they face four major risks: bacterial infections from unhygienic ice vendors, high potassium levels from ingredients like beans and peanuts which can cause heart rhythm problems, high fructose and phosphate content in syrups and condensed milk that damage kidneys and harden blood vessels, and fluid overload leading to pulmonary edema.

Kidney patients are not completely unable to eat ice, but for patients with severe kidney failure, especially those in stage 4 or above, they need to pay more attention to the following 4 major crises.

For those seeking to cool down, Dr. Hong suggests safer alternatives. These include sucking on ice cubes made from filtered water at home, choosing low-potassium toppings like grass jelly or pudding when eating out, and strictly controlling portion sizes, perhaps sharing a small amount with family. He emphasizes the importance of choosing vendors with strict hygiene standards.

Suck on pure water ice cubes: Freeze small ice cubes made from filtered boiled water at home and suck on them. You get the cooling sensation, and the amount of water swallowed is very small, which is hygienic and safe.
