Have you ever heard of a "Nephrologist"? Maybe your doctor has referred you to one. Or maybe someone in your family has heard the name because of a kidney problem. Who exactly is a nephrologist? What exactly do they do? Let's talk about this simply and clearly.
Who is this nephrologist?
Simply put, a nephrologist is a doctor who specializes in kidney diseases and their function. Just as there is a cardiologist for the heart, a nephrologist is a doctor who specializes in kidneys.
The kidneys are two small but amazing organs in our body. These bean-shaped organs are a major part of our urinary system. Their main job is to filter our blood, remove waste products, excess water, and electrolytes from it, and excrete them as urine. So, if there is a problem with these kidneys, it can affect the entire body. That is when we need the help of a nephrologist.
Are there nephrologists for young children?
Yes, absolutely. We call doctors who specialize in kidney diseases in newborns, young children, and young adults pediatric nephrologists .
What exactly does a nephrologist do?
A nephrologist not only diagnoses and treats kidney disease, but they also understand the effects of kidney disease on other parts of the body. For example:
- High Blood Pressure: Sometimes high blood pressure can damage the kidneys. Sometimes high blood pressure can be caused by a problem with the kidneys. A nephrologist is well aware of the connection between the two.
- Cardiovascular disease: When kidneys fail, it directly affects the heart.
- Autoimmune diseases: In some diseases, our body's own immune system attacks our kidneys. A nephrologist can also help manage these conditions.
What is the difference between a nephrologist and a urologist?
This is something that confuses many people. Because both of these doctors work on kidneys. But there is a big difference in their work. Let's look at it from a table.
| Section | Nephrologist | Urologist |
|---|---|---|
| Main focus | Diseases that affect kidney function (e.g., kidney damage due to diabetes, high blood pressure). | Diseases that affect the entire urinary system (kidneys, bladder, urethra) as well as diseases of the male reproductive system. |
| Treatment methods | Often, non-surgical treatments such as medication and dialysis are used. | There is the possibility of surgery as well as medication. |
| Examples of eye diseases | Kidney failure, nephrotic syndrome, kidney disease caused by diabetes. | Kidney stones, bladder cancer, urinary tract infections (UTIs), prostate problems. |
Simply remember: If you have a problem with your kidneys' ability to function, you should see a nephrologist. If you have something that needs to be surgically removed , like kidney stones, or another problem with your urinary system, you should see a urologist.
What are the common diseases that a nephrologist treats?
Here are some of the conditions that a nephrologist most commonly treats:
- Diabetic kidney disease: People with diabetes can develop kidney damage over time.
- High blood pressure: Uncontrolled high blood pressure is a big enemy for the kidneys.
- Kidney failure: The sudden (acute) or gradual (chronic) loss of kidney function.
- Kidney stones: A nephrologist treats some types of kidney stones to prevent them from recurring.
- Nephrotic syndrome: A condition in which large amounts of protein are excreted in the urine.
- Urinary Tract Infections (UTIs): Find the cause of frequent urinary tract infections.
- Electrolyte imbalances: Abnormally low or high levels of things like sodium and potassium.
- Toxic overdoses requiring dialysis.
When should you see a nephrologist?
Your general practitioner (GP) will often refer you to a nephrologist. Here are some reasons why:
- Having a family history of kidney disease: If your mother, father, or siblings have kidney disease, you may also be at risk.
- Having diabetes: Everyone with diabetes should have their kidney function checked periodically.
- Having high blood pressure: High blood pressure can also damage the kidneys.
- Changes in urine:
- Blood in the urine.
- Foamy urine (may be a sign of protein excretion).
- Passing more or less urine than normal.
- Abnormalities in blood and urine tests: A doctor may refer you for things like elevated creatinine levels in your blood, protein in your urine, or blood cells.
- Brain fog: Sometimes, when the kidneys are not working properly, toxins that accumulate in the body can cause difficulty concentrating, forgetfulness, and confusion.
How do you prepare for a visit to a nephrologist?
If you're going to see a nephrologist for the first time, it's worth going a little prepared. That way, it'll be easier for both you and the doctor.
1. Take all your old medical records: Put all your old blood reports, urine reports, and scan reports in a file and take them with you in an orderly manner.
2. Make a list of your current medications: Make a list of all the medications you take (including those for other conditions). Write down the names of the medications, the dosage, and how many times a day you take them. It's best to bring all of your medications with you if possible.
3. Write down your symptoms: Keep a journal of your symptoms, including when they started, and when they worsen.
4. Know your family medical history: Find out if anyone in your family has kidney disease, diabetes, or high blood pressure.
5. Be prepared to ask questions: Write down the things you want to know and the questions you have in mind. You may forget them when you meet the doctor.
6. Go with someone: If possible, go with a family member or friend. It's a great help to listen to and remember what the doctor says, and to have someone to help you.
During your first appointment, the doctor will ask about your symptoms, examine you, review your past medical records, and order some new blood or urine tests if necessary. There's nothing to worry about. All of this is done to find the best solution for your problem.
