Stage 3 Kidney Disease Life Expectancy - An Insight

Introduction

The term "kidney disease" refers to a group of illnesses that impair the kidneys' capacity to remove waste and extra fluid from circulation. Acute kidney injury (AKI), kidney stones, and chronic kidney disease (CKD) are common forms. Kidney-related problems should be seen by a doctor immediately because they can have a negative impact on the condition of the body. Depending on the particular illness and its severity, different treatments are available.

With an estimated glomerular filtration rate (eGFR) between 30 and 59 mL/min per 1.73 m2, stage 3 renal disease is characterized by substantially impaired kidney function. The kidneys may struggle to filter waste and extra fluid from the blood at this time, but it is frequently treated with dietary adjustments, medication, and constant observation.

What Are the Signs of Stage 3 Kidney Disease?

Kidney function noticeably declines in stage 3 kidney disease, commonly known as mild chronic kidney disease (CKD). The following are frequent warning indicators and symptoms:

• Fatigue: Being unusually fragile or exhausted.

• Swelling: Edema or swelling of the face, ankles, or feet.

• Changes in Urination: Urination changes, including variations in frequency, color, or foaminess.

• Blood in Urine: Hematuria, or blood in the urine, can be either visible or microscopic.

• Increased Thirst and Urination: Increased frequency of urination, especially at night (nocturia), in addition to an increase in thirst.

• High Blood Pressure: Kidney disease can have hypertension as a symptom or as a primary cause.

• Elevated Creatinine Levels: Blood tests can detect elevated creatinine levels, which are indicative of impaired kidney function.

• Electrolyte Imbalances: Abnormalities in the electrolytes, such as having too much potassium (hyperkalemia) or too much phosphorus (hyperphosphatemia).

What Is the Diagnosis of Stage 3 Kidney Disease?

The diagnosis of stage 3 renal disease is frequently made using a combination of examinations and tests. It is distinguished by a mild decline in renal function. For a stage 3 kidney disease diagnosis, doctors could include

• Blood Tests: A crucial marker is the glomerular filtration rate (GFR). GFR is greater than 30 mL/min, but less than 60 mL/min is often linked to stage 3.

• Tests on the Urine: Finding protein or blood in the urine can reveal more details about the condition of the kidneys.

• Imaging: Imaging examinations such as ultrasounds, CT (computed tomography) scans, or MRIs (magnetic resonance imaging) may be used to measure the kidneys' size and structure.

• Medical History and Physical Exam: For the purpose of checking for kidney disease symptoms and signs, the physician will probably go over the medical history and perform a physical exam.

• Kidney Biopsy (In Some Circumstances): If there are particular worries regarding the source of kidney disease or to assess the degree of damage, a kidney biopsy may be carried out.

When trying to manage stage 3 kidney disease, it is vital to collaborate closely with a medical professional to determine an accurate diagnosis, go through treatment choices, and decide on lifestyle adjustments.

What Is the Life Expectancy of Stage 3 Kidney Disease?

Age and lifestyle can affect estimates. According to one of these estimates, women and men in the same age group can expect to live an average of 28 and 24 years, respectively, after turning 40. In addition to general life expectancy, it is vital to take the possibility of disease progression into account.

Half of the kidney's function is present in stage 3 renal disease, and the majority of patients also have ancillary issues like high blood pressure or bone abnormalities. The all-cause death rate for stage 3 renal disease ranged from six percent in three years to 51 percent in 10 years, according to a review of 13 studies.

What Is the Management of Stage 3 Kidney Disease?

There is no cure for kidney damage that has already occurred if stage 3 renal disease is identified in a patient. The next steps in medical treatment focus on managing the problems caused by decreasing kidney function and averting future harm.

• Maintaining routine consultations with the physician, neurologist, or any other specialist they may require to see.

• Blood sugar control if they have diabetes.

• Avoiding drugs that worsen kidney damage.

• Monitoring and managing the blood pressure.

• Limiting protein and foods with high cholesterol, salt, and potassium.

• Not smoking.

• Working out and remaining active.

• Keeping an eye on the weight to be healthy.

• Addressing anemia.

Dialysis or a kidney transplant are not necessary treatments for stage 3 CKD. Instead, patients will be given prescriptions for specific drugs to treat underlying illnesses that could be causing kidney damage.

They might also need to take medicine. The type of medication one has to take and even the amount they take should depend largely on the reason for the kidney disease. Some examples of these medicines include

• Reducing blood pressure by inhibiting angiotensin-converting enzyme (ACE).

• A drug called an ARB, or angiotensin receptor blocker would help lower the blood pressure.

• Diuretics to aid in waste removal.

• Medications of any kind that could lower cholesterol levels.

• Erythropoietin which assists those with anemia in producing red blood cells.

• Vitamin D protects against bone loss and promotes bone health.

• Phosphate binder (if people are having trouble getting rid of phosphate).

What Is the Diet Recommended for Stage 3 Kidney Disease?

• The body is negatively impacted by processed foods. Eating too many of the wrong meals can overwhelm the kidneys because they are in charge of eliminating waste and maintaining electrolyte balance.

• It is vital to consume more fresh produce and whole grains while limiting processed meals and animal products' saturated fat intake.

• The physician could advise consuming less protein. They should also counsel patients against consuming potassium-rich foods like bananas, potatoes, and tomatoes if they have CKD and their potassium levels are too high.

• The same idea applies to sodium. If the levels of sodium are excessively high, they might need to reduce the amount of salty foods. Due to appetite loss, weight loss is frequent in more severe stages of CKD. One may also become malnourished as a result of this.

• Try consuming more smaller meals throughout the day, if they are losing their appetite. Make sure that they are consuming enough calories and nutrients.

Conclusion

Treatment for stage 3 chronic renal disease aims to stop future progression. There is no treatment for CKD at any stage, and renal damage cannot be reversed. However, if it is at stage 3, additional damage can still be reduced. In stages 4 and 5, prevention of advancement is increasingly challenging.
