The first bubble of cloudy urine when you get up in the morning may be caused by concentrated urine. In this case, you have to distinguish whether there is any discomfort, and you can also have a routine urine test to see what the urine routine really is, whether there are white blood cells, whether there is proteinuria, whether there are a lot of organic and inorganic salts and nitrites. If there are no symptoms, you may not drink enough water, or you may have eaten a lot of protein and fatty foods the day before. After these substances are metabolized in the body, they produce a lot of organic and inorganic salts, which require a lot of water for digestion in the body, resulting in a lack of urine volume in the body, concentrated urine, and a lot of organic and inorganic substances in the urine, which will appear cloudy. It is recommended to drink more water and observe closely.
