The yellow urine in the morning is often due to the concentration of urine, because the urine is stored in the bladder for a relatively long time, especially if the patient does not urinate at night, the urine will be concentrated to varying degrees after getting up in the morning, resulting in a yellow color, even with a certain odor and other circumstances, which is a normal situation rather than a disease condition. At this time, there is no frequency, urgency and painful urination symptoms. Patients can drink more water after urination and their urine will return to its normal color, so they do not need any treatment, but only need to drink more water during the day or rehydrate at night. In addition, it is also necessary to exclude disease conditions, for example, patients may have urinary tract infections, except for the yellow color of urine in the morning, which is often accompanied by pain during urination or a sense of incomplete urination, frequent urination, or even back pain. In this case, if the urine color does not improve significantly after drinking more water, and the symptoms of urinary tract irritation do not improve significantly, it is recommended to go to the hospital for urinalysis to confirm the diagnosis of infection.
