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.

Can patients with IgA nephropathy eat beef?

Diet plays a very important role in the treatment of IgA nephropathy patients. For IgA nephropathy patients, the general dietary requirement is to eat a light diet, avoid spicy foods, and avoid fried foods. IgA nephropathy patients can eat beef. Beef contains animal protein, which is a high-quality protein with essential amino acids that are easily absorbed and utilized by the human body. Of course, if IgA nephropathy patients have normal kidney function, there aren't too many restrictions on their diet compared to healthy individuals. They should mainly consume fresh vegetables and fruits, and avoid pickles, salty vegetables, and fermented vegetables. If there is accompanying kidney dysfunction, it is advisable to minimize the intake of plant proteins and limit the consumption of plant-based proteins such as soy products.

Can patients with IgA nephropathy eat peaches?

Patients with IgA nephropathy vary greatly in the severity of their condition, and whether they can eat peaches depends on their individual disease state. If a patient does not have increased creatinine levels and no edema, they can eat peaches like a normal person without any restrictions on quantity. If the patient has increased creatinine levels, they need to control the amount of peaches they consume. This is because, in patients with elevated creatinine, the glomerular filtration rate is decreased, and a decrease in glomerular filtration rate can lead to an inability to expel excess potassium ions from the body. Peaches are a fruit with a high potassium content, and if such patients consume too many peaches, it can lead to hyperkalemia. Mild cases may experience weakness and numbness in the limbs, while severe cases can lead to potentially fatal cardiac arrhythmias.

Can patients with IgA nephropathy have sexual intercourse?

Patients with IgA nephropathy can engage in sexual intercourse, but there are certain prerequisites. Firstly, this disease is not contagious, and it will not be transmitted to the partner during intercourse. Secondly, there is not a significant relationship between renal function and sexual capability; patients with kidney diseases typically retain normal sexual and reproductive functions. However, since sexual activity requires a certain amount of physical strength, and in cases where the patient's condition is particularly severe, it might render the patient unable to engage in sexual activities. Therefore, if the patient does not have significant hypertension, severe edema, especially genital edema, pulmonary edema, or heart failure, they would be capable of engaging in sexual activities, and thus can have intercourse.

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.

Is IgA nephropathy grade 3 serious?

IgA nephropathy is divided into five stages pathologically, with stage three being the focal proliferative type. The higher the stage, the more severe the condition of IgA nephropathy. Stage three is in the early to middle phase, where generally the condition of the patients is comparatively good, and rarely worsens to uremia, belonging to the low-risk group. Clinically, patients with stage three IgA nephropathy often exhibit repeated occurrences of gross hematuria or persistent microscopic hematuria. Some patients may also experience varying degrees of increased urinary protein. Patients with this stage of IgA nephropathy rarely suffer from hypertension or renal insufficiency, but it is essential in daily life to avoid nephrotoxic drugs, prevent infections, seek medical attention promptly upon infection, and regularly follow up on routine urine and renal function changes. If the condition tends to worsen, active treatment should be pursued.
