Stage 2 kidney disease causes mild loss of kidney function, the kidneys are still functioning properly, and the patient can still manage symptoms.

Chronic kidney disease (CKD) is a condition in which the kidneys are damaged and cannot function properly. The most common causes of CKD are diabetes and high blood pressure, in addition to infections, genetic disorders, and heavy metal poisoning.

There are 5 stages of kidney disease, ranging from mild CKD (stage 1) to end-stage CKD, kidney failure (stage 5). In people with stage 2 kidney disease, an estimated glomerular filtration rate (eGFR) is about 60-89, protein in the urine, or mild kidney damage.

Symptoms and Diagnosis

Early-stage kidney disease may not have any specific symptoms. Even with minor damage, the kidneys are still functioning properly. This is why only about 10% of people with chronic kidney disease at this stage know they have it.

With blood and urine tests, your doctor can check for protein in the urine (albuminuria), creatinine in the blood and urine, and eGFR to help determine the stage of stage 2 kidney disease. Signs that the kidneys are not working properly. As the disease progresses, the kidneys gradually decrease in function, waste products accumulate and the patient begins to notice obvious symptoms. Imaging tests such as ultrasound also help to more specifically assess the extent of kidney damage.


Kidney disease cannot be cured. The main treatment methods control symptoms, prevent disease progression, reduce the risk of kidney failure, promote health…, including:

Diet: This is important both to help control blood pressure and blood sugar, and to delay and prevent related health problems. Although in stage 2, kidney disease may not have any symptoms, but it is not too early for patients to actively adjust their diet. Some dietary tips include: prioritizing lean protein, eating more whole grains, fruits and vegetables, limiting salt and sugar, drinking enough water, adding healthy fats like olive oil, omegas 3 and nuts.

Life style: Quit smoking and alcohol, and increase physical activity for at least 30 minutes a day, 5 days a week (consult your doctor). These ways can help control blood sugar and help maintain a healthy weight.

EASYDrug use: Medicines may not be necessary at this stage, but depending on the patient’s condition, it is important to consult your doctor before taking any medication.

Risk of death and chance of survival

The life expectancy of people with chronic kidney disease can vary, depending on many factors such as age, health status, and lifestyle behaviors. However, general statistics show that people with stage 2 kidney disease (with an eGFR of 60 or more) can live for 3 to 44 years, or even higher.

Because mild kidney disease doesn’t have as many typical symptoms as severe kidney disease, people may not know they have it unless they go for a checkup. With early detection, specialists can devise a treatment plan to slow the progression of the disease and delay kidney failure for as long as possible, keeping patients alive longer.
