Yellow urine after applying quadruple therapy (referring to quadruple therapy for H. pylori) may be caused by adverse drug reaction, low water intake, food, urinary tract infection and other factors.
1. Adverse drug reactions: If furazolidone or tetracycline is used in the quadruple therapy for H. pylori, it may make the urine yellow, which is a normal adverse drug reaction and can be gradually recovered after stopping the drug.
2. Reduced water intake: If the user reduces the amount of water intake during the medication, the urine will turn yellow after concentration, and can be restored by increasing the amount of water intake.
3. Food: If you eat too much yellow food such as oranges, carrots, pumpkins, etc. during the period of taking the medicine, it may lead to the yellowing of urine, which can be restored to normal after stopping eating the above mentioned food.
4. Urinary tract infections: When urinary tract infections, certain bacteria present in the urinary tract can interact with the urine and make it turn yellow.
The patient should go to the hospital in time, and follow the doctor’s prescription of medication.
