Chronic Kidney Disease
Body System: Renal & Urological System | Area Affected: Kidneys, ureters, bladder, and urethra
Doctor to Consult: Nephrologist or Urologist
What It Is
Chronic Kidney Disease: Chronic kidney disease (CKD) is a type of long-term kidney disease, defined by the sustained presence of abnormal kidney function and/or abnormal kidney structure. To meet the criteria for CKD, the abnormalities must be present for at least three months. Early in the course of CKD, patients are usually asymptomatic, but can be diagnosed via proteinuria. At later stages, the symptoms may include leg swelling, feeling tired, vomiting, loss of appetite, and confusion. Complications can relate to hormonal dysfunction of the kidneys and include high blood pressure, insulin resistance, bone disease, and anemia. Additionally CKD patients have markedly increased cardiovascular complications with increased risks of death and hospitalization. CKD can lead to end-stage kidney failure requiring kidney dialysis or kidney transplantation.
Why It Happens
Chronic Kidney Disease arises due to factors affecting the Renal & Urological System. Kidney and urological conditions develop from mineral imbalances, infections, obstruction of urinary flow, or progressive loss of kidney filtration capacity. While individual cases vary, a combination of genetic susceptibility, lifestyle factors, and environmental exposures typically contribute to the development of Chronic Kidney Disease.
Who Gets It / Risk Factors
Who Is at Risk for Chronic Kidney Disease
Kidney disease risk increases with diabetes, hypertension, and age above 60. UTIs are more common in women.
A family history of renal & urological system conditions may increase susceptibility to Chronic Kidney Disease.
Contributing Factors
Chronic dehydration, high-sodium diet, uncontrolled diabetes or hypertension, and recurrent urinary infections.
Co-existing health conditions such as diabetes, hypertension, or cardiovascular disease may compound the risk.
When to Seek Emergency Care
Inability to urinate, severe flank pain with vomiting, bloody urine, or signs of kidney failure related to Chronic Kidney Disease.
Sudden or rapidly worsening symptoms that impair basic daily function.
Difficulty breathing, severe pain, loss of consciousness, or high fever with confusion.
