Foam is rarely considered a good thing in economic life or in daily life, and it is the same for patients with hypertension. The presence of a large amount of foam in the urine indicates a possible kidney problem, which is an important sign of a possible kidney problem in patients with hypertension and diabetes. There are many reasons for the appearance of foam in urine: for example, men have a greater chance of having foam because they stand to urinate, while women have relatively less, and the protein content in urine is higher than normal. If you are a patient with high blood pressure, a diabetic patient or a patient with no obvious signs of other diseases, but have excessive urine foam for a long time, you should have a high suspicion of kidney problems. This test is urinalysis and urine microprotein measurement. Generally speaking, the absence of problems in urinalysis does not confirm that there is no problem with the smooth kidney, because there are some patients with hypertension or early stage of diabetic nephropathy who only have trace proteinuria, which cannot be detected by routine examination and can only be detected by special urine biochemical tests. Therefore, it is recommended that every person suffering from hypertension or diabetes, do not flush it out immediately after urinating, look back, if there is a lot of foam and it does not dissipate for a long time, you should find a doctor and check the urine biochemistry to exclude hypertensive nephropathy or diabetic nephropathy. As we all know, kidney disease most need early detection, early treatment, and avoid drugs that damage the kidneys and pay more attention to reduce the damage to the kidneys and reduce or end-stage renal disease – the possibility of uremia or delay the occurrence of end-stage renal disease – uremia. To rule out kidney problems, routine urine tests can be performed first, and if there is no problem, further random urine biochemistry is required, and if there is a problem, the nocturnal urine 8-hour urine microalbumin excretion rate, renal function and other indicators are required. For the early stage of microproteinuria, most of them can be better controlled after treatment. Therefore, once microproteinuria is identified, it indicates early glomerular or tubular damage. At this stage of treatment, it is important to actively treat the primary disease and actively protect the kidneys, as the heart, liver and kidneys are important organs in our body, and these three can affect each other. Patients with hypertension with a history of more than 5 years have a high chance of developing microproteinuria, but there are also some hypertensive patients with a history of less than 5 years who develop microproteinuria. Therefore urine tests and urine biochemistry can be used as part of the routine screening for a history of hypertension. Foam in urine is a God-given clue to early detection of diabetes mellitus or hypertensive nephropathy in humans. Friends, after urinating, you may want to look back and see if there is a lot of foam or if the foam does not go away for a long time.
