What Is Nephrology?

Nephrology is a branch of internal medicine that focuses on the diagnosis and treatment of kidney diseases. Kidneys are a pair of bean-shaped organs located on either side of the spine, in the back of the abdomen, just below your rib cage.

Kidneys are the human body’s natural filtration system, which forms an integral part of the urinary system. They remove waste products and excess fluid from your bloodstream. They are also vital for maintaining proper concentrations of electrolytes like sodium, potassium, and calcium, which can fluctuate due to various conditions or even medications.

There are several subspecialties under renal nephrology. Two important ones are transplant and interventional nephrology.

Transplant nephrologists specialize in pancreas and kidney transplants, both surgical procedures and post-transplant care for recipients. Interventional nephrology focuses on specific procedures and interventions to access blood vessels during dialysis. Interventional nephrologists are trained in several areas, including catheter placement and removal, stent placement, blood clot removal, fistulograms, and kidney biopsies.

Nonetheless, nephrology extends beyond kidney health. Some kidney-related conditions are systemic, affecting the entire body and not just confined to one organ. Such disorders demand specialized treatment and medical care, which is where nephrologists come into play.

Who Is A Nephrologist? What Do They Treat?

Nephrologists are renal doctors who are experts in caring for the kidneys. They are responsible for diagnosing, treating, and managing various kidney-related issues. Nephrologists who focus on kidney care for newborns and children are referred to as pediatric kidney specialists or nephrologists.
Nephrology diseases treated by renal specialists can range from common issues like kidney stones to more complex and chronic ailments such as chronic kidney disease (CKD), renal failure, and end-stage renal disease.

  • Kidney, bladder, and urethra cancers.

  • All types of renal failures–acute, sudden, chronic, or long-term.

When Should You See A Nephrologist?

If you experience any kidney disease symptoms, you should immediately consult a nephrologist. Here are some of the most common kidney damage symptoms.

  • Persistent swelling in the legs, ankles, or feet
  • Frequent, unexplained headaches
  • Dry and itchy skin
  • Nausea
  • Reduced sense of taste or appetite changes
  • Low energy levels and difficulty concentrating
  • Brain fog, confusion, forgetfulness
  • Joint pain or stiffness
  • Irregularities in blood pressure, especially high blood pressure
  • Muscle cramps, numbness, and weakness
  • Sleep disturbances
  • Hematuria (blood in the urine)
  • Decreased urine output, unrelated to dehydration
  • Unexplained weight loss

In addition to these kidney issue symptoms, a biological family history of renal diseases puts you at a greater risk of nephrological diseases. Furthermore, diabetes is known to have adverse effects on the kidneys. So, if you have diabetes, you’re at an increased risk of renal complications.

Regular check-ups with a nephrology specialist can help monitor your kidney health and take preventive measures.

Your health is our priority.

Our Answers To The Most Frequently Asked Questions About Nephrology

What is the difference between nephrology and urology?

Nephrology and urology are two medical specialties that focus on different aspects of the urinary system. Renal nephrology deals with the study and management of kidney function, and nephrologists specialize in diagnosing and treating kidney-related issues. Whereas urology covers a broader spectrum of conditions related to the entire urinary system (kidneys, bladder, ureters, and urethra). Urologists also diagnose and treat conditions affecting the male and female reproductive systems.

What are the 3 early warning signs of kidney disease?

The early signs of kidney diseases include changes in the frequency of urination or dark or foamy urine, unexplained swelling in your ankles, legs, or around the eyes, fatigue, weakness, and a general feeling of being unwell despite adequate rest. If you experience any signs of kidney issues, it is important to consult a kidney specialist doctor for thorough evaluation and appropriate treatment. Early detection and management can significantly improve outcomes and prevent further complications.

What is stage 1 kidney disease?

Stage 1 kidney disease or stage 1 Chronic Kidney Disease (CKD) is the earliest and mildest stage of renal impairment. In this stage, though there are subtle signs of damage, the kidney functions remain largely normal. Key indicators of stage 1 CKD include protein in urine without a significant decline in glomerular filtration rate (GFR)–90 ml/m. Individuals don’t experience noticeable CKD symptoms, but monitoring the condition and implementing preventive measures before it proceeds to stage 2 or stage 3 kidney disease is crucial.
