Morning urine has foam during the day. What's going on?

Morning urine foam and no daytime, mostly because of urine concentration. Because morning urine is mostly stored in the bladder at night, urine stored in the bladder for more than 4 hours, will show varying degrees of concentration, urine solute concentration, such as electrolytes, protein and other components are relatively high, so the urine will show foam, foam volume is large, and quickly dissipated. At the same time, in the process of urination, there will be no urination stimulation symptoms and pain symptoms, and the patient will not show edema in the limbs, face, etc. During the day, due to factors such as diet or drinking more water, urine will not show concentrated conditions, and the discharged urine will be clearer, transparent, and will not be accompanied by foam. This is a normal physiological condition, not a disease condition, patients do not need to pay too much attention, usually only need to maintain a certain amount of water can be properly, no special treatment.
