IgA nephropathy is a pathological type of chronic glomerulonephritis. The clinical manifestations of this disease are diverse, with the typical clinical presentation of IgA nephropathy being hematuria, especially visible hematuria following a cold.

However, patients may also exhibit other features, such as significant amounts of urinary protein. In some cases, this can reach the level of 3.5g in a 24-hour urine protein quantification. Patients may experience edema, such as swelling in the lower limbs, eyelids, etc. There could also be clinical presentations of high blood pressure, rapid progression of renal failure, and other symptoms.

What will happen if someone with IgA nephropathy stays up late?

IgA nephropathy is a very common glomerular disease in clinical settings and is one of the main causes of uremia. IgA nephropathy is most commonly seen in adolescents, particularly in males. The cause of IgA nephropathy is currently unclear, but the clinical manifestations of patients with IgA nephropathy are numerous and vary in severity. For patients with milder IgA nephropathy, it is important to maintain a healthy lifestyle, avoid staying up late, overworking, and infections. Frequently staying up late can aggravate the condition, leading to significant proteinuria and even worsening kidney function. Therefore, it is crucial for patients with IgA nephropathy to regularly monitor their urinalysis, kidney function, and blood pressure, maintain a regular lifestyle, and avoid various adverse lifestyle impacts. Of course, once the condition worsens, it is important to seek medical attention promptly and pursue active treatment.

How to control IgA nephropathy?

IgA nephropathy is a very common type of glomerular disease in clinical practice and is also a major cause of uremia. Therefore, sufficient attention should be given to IgA nephropathy by patients, and active treatment is required. The treatment of IgA nephropathy usually depends on the clinical manifestations and pathological types of the patient, meaning that the treatment approaches for patients with different clinical manifestations of IgA nephropathy are not exactly the same. For patients who frequently experience gross hematuria, if it is related to tonsil infection, it is recommended that the patient undergo tonsillectomy. For patients with IgA nephropathy who only have microscopic hematuria, there is generally no need for special medication treatment. However, in daily life, regular monitoring of routine urine tests, kidney function, and blood pressure is necessary, and the use of drugs that are toxic to the kidneys should be avoided. For patients with IgA nephropathy who also have significant proteinuria, even nephrotic syndrome, treatment often requires the use of steroids, and even immunosuppressants. For patients with mild to moderate proteinuria, it is recommended to use angiotensin-converting enzyme inhibitors or angiotensin receptor blockers. Only in this way can the condition of IgA nephropathy be controlled.

Can IgA nephropathy patients eat watermelon?

IgA nephropathy is a chronic glomerulonephritis with varying degrees of severity and diverse clinical manifestations. Whether patients can eat watermelon depends on their kidney function and the presence of edema symptoms. If patients have kidney failure and noticeable edema, it is advised that they avoid eating watermelon, as it contains a significant amount of potassium ions. Consuming watermelon may lead to hyperkalemia due to the intake of large amounts of potassium ions. The main component of watermelon is water, and if patients have noticeable symptoms of edema, eating watermelon may exacerbate these symptoms and even cause issues like hypertension. If patients do not have noticeable edema and their kidney function is normal, eating small amounts of watermelon should not be a major concern.

The characteristics of proteinuria in IgA nephropathy

IgA nephropathy is a pathological type of chronic glomerulonephritis, which can cause patients to exhibit symptoms such as proteinuria and hematuria. Regarding the characteristics of proteinuria, it is generally primarily glomerular proteinuria. In the classification of patients' proteinuria, glomerular proteinuria accounts for a large proportion. If IgA nephropathy presents as chronic nephritis or nephrotic syndrome, the patient's level of proteinuria will be quite severe, with significant amounts of proteinuria, where the 24-hour urinary protein quantification may exceed 1g or even reach more than 3.5g. However, not all patients with IgA nephropathy have such high levels of proteinuria; some may only have mild proteinuria.

Kidney disease IgA means IgA nephropathy.

Kidney disease IgA, formally known as IgA nephropathy, is an immunological diagnostic term for chronic glomerulonephritis. It is characterized by the deposition of immune complexes, primarily IgA, in the mesangial areas of the glomeruli. IgA is a type of immunoglobulin, which upon deposition in the kidneys induces inflammatory responses, leading to proliferation of mesangial cells, accumulation of mesangial matrix, and widening of the mesangial area. This can cause damage to the glomerular filtration barrier, manifesting as proteinuria and hematuria. Some patients may also develop crescent formations in the glomeruli, leading to renal failure.
