Foamy urine in the morning may be due to physiological factors such as excessive protein intake, or it may be due to nephrotic syndrome, renal tubular pathology, diabetic nephropathy and other causes.
1. Foamy urine in the morning may be physiological proteinuria, which may be related to physiological factors such as mental tension, sympathetic nerve excitement, excessive protein intake, etc. Of course, excessive force of urination can also lead to foamy urine.
2. Nephrotic syndrome: glomerular immune material deposition leads to glomerular filtration membrane barrier function is impaired, a large amount of protein into the urine, more than the proximal tubular reabsorption of protein limit, proteinuria, and thus will be the morning urine with foam.
3. Renal tubular disease: the proximal tubular reabsorption of protein function decreases, resulting in increased protein content in the urine, thus morning urine foam.
4. Diabetic nephropathy: diabetic patients with increased glucose content in the urine, glomerular hyperperfusion leads to protein into the urine and other factors cause proteinuria, so there will be foamy urine in the morning.
Foamy urine in the morning may be related to a variety of factors, it is recommended to consult a doctor for a clear diagnosis.
