Morning urine is the first urine that is passed in the early morning after waking up, before breakfast, exercise, etc. There is usually no specific value for morning urine. But it usually amounts to about 200 ml – 500 ml. The amount of urine in the morning urine is related to the amount of time the patient sleeps, as well as the amount of water he/she drinks before going to bed, and the amount of food he/she consumes that contains a lot of water. If you drink a lot of water before going to bed, you will pass more urine. Drinking less water or having such kidney-damaging diseases as uremia will result in less urine. So there is generally no specific value. There are many factors that affect the amount of urine in the morning, so if you feel that the amount of urine is abnormal, you can go to a regular hospital and under the guidance of the doctor for examination to confirm the diagnosis.
