Excessive intake of protein-based foods can cause an increase in urea, such as eggs, duck eggs, lean meats, soy products, and fish foods, all of which are rich in protein and can easily cause an increase in urea content. Or a large amount of food that is too acidic for a long period of time can also lead to an increase in urea. Eating too much food high in purines, such as seafood, poultry, and offal, can also increase urea levels. If the urea level is high, it is recommended to reduce the total calorie intake of food, limit the intake of purine, eat less animal offal, limit the intake of protein, eat more vegetables and fruits, eat more alkaline food, and stop drinking alcohol, especially beer. It is recommended to drink a lot of water every day to increase the amount of urine, which can reduce urea, and avoid overexertion. If necessary, you can take oral sodium bicarbonate to alkalize the urine to prevent urinary stones.
