Men urinate when there is foam, the reasons are very many, not necessarily a serious situation, as follows: First, there is no basic disease in men when the urine foam, may be the urine concentration state, urine in the fall of the shock, the role of physical shock can produce a kind of stirring foam, which is a non-pathological state. Secondly, it may be that the food that men eat during this period of time, such as eating food containing protein or other food too much, may also appear in different temperatures to change the amount of foam, this is also a non-pathological situation. Third, if this male has kidney disease or diabetes, a long history, poor blood sugar control, it is likely to have complications of diabetes, nephropathy, urine appears foam, we should think that it may be the increase in the protein content of the urine, the foam caused by the protein urine discharged. Fourth, urinary tract infections, urinary tract infections when there are many bacteria in the urine, the cell structure of bacteria is actually protein, so the disintegrating fragments of these bacterial cells, can also produce foam-like conditions when urinating. All in all, men who have foamy urine when there is no underlying disease are generally not a big problem, but if they have some disease of their own and have foamy urine, they should go to the hospital for further examination to determine if it is a serious disease state.
