Chronic nephritis, also known as chronic glomerulonephritis, has a slow onset and slow progress. The main clinical manifestations are hematuria and proteinuria. What patients with chronic nephritis can eat depends on whether there is edema and abnormal renal function, and choose appropriate food and medicine.

First, food:

1, mild edema, normal renal function: these patients have mild illness, short medical history, mild edema and normal renal function, and their diet can be relaxed appropriately. Generally, it is recommended to eat a low-salt and low-fat diet, eat high-quality protein food in moderation, such as chicken, fish and lean meat, and supplement essential amino acids. Because nephritis patients are usually complicated with hypertension, it is recommended to eat a low-salt diet with a daily salt intake of < 6g. People without diabetes can choose fresh vegetables and fruits to eat, such as vegetables, cucumbers, apples and oranges. However, due to the high water content of these foods, it is recommended to eat them properly so as not to aggravate edema;

2. Patients with severe edema and abnormal renal function: Due to the severe edema of such patients, while strictly limiting salt, it is necessary to limit the amount of drinking water, and keep the daily liquid intake at the previous day's urine volume +500ml. At the same time, on the premise of ensuring high-quality protein diet, the daily intake of protein needs to be reduced appropriately. In addition, considering the risk of hyperkalemia after renal dysfunction, foods with high potassium content in daily life, such as green leafy vegetables, bananas, oranges, kiwis and peas, should be strictly restricted.

Second, drugs:

Patients with chronic nephritis need to control hypertension, and angiotensin converting enzyme inhibitors, such as captopril sustained-release tablets and enalapril maleate dispersible tablets, can be used under the guidance of doctors. The drug can reduce systemic hypertension, reduce intraglomerular pressure, reduce glomerular hyperhemodynamics and delay the progress of renal failure. In addition, calcium antagonists can also be selected for treatment, which has a positive effect on delaying the deterioration of renal function. The common drugs are levoamlodipine maleate tablets, nifedipine sustained-release tablets and nicardipine hydrochloride sustained-release tablets.
