What is the reason for yellow and milky urine?

Patient's question:

Basic Information: Male, 5 months
Condition Description: Felt fever last night, observed yellow and milk-like urine today. Haven't noticed it before, only discovered it today. Previously, there were yellow stains on the diaper.

Doctor's answer:

Hello, the condition of the child is considered to be caused by an internal heat issue. It is recommended that you go to the hospital for a urine test to check if there are any problems in the urine. When fever occurs, there will be increased respiratory rate, and body fluids will be lost more through respiration. This leads to a relative decrease in blood volume, causing urine to become more concentrated and appear darker in color. Alternatively, you can give the baby a probiotic powder to supplement beneficial gut bacteria and promote digestion.
