questions to ask before kidney

Overview

This article helps you prepare for conversations with your healthcare team about your kidneys. It lists important questions to ask before any kidney treatment or procedure, such as dialysis, transplant, or surgery. The aim is to help you understand your condition and make informed choices.

Chronic kidney disease affects about 1 in 10 adults worldwide. Many people do not know they have it until it is advanced.

It can affect anyone, but is more common in people with diabetes, high blood pressure, heart disease, or a family history of kidney disease. It also becomes more common with age.

Symptoms

Common symptoms

• Feeling tired or weak
• Swelling in the feet, ankles, or hands
• Changes in how much you urinate or how it looks
• Itchy or dry skin
• Loss of appetite or weight loss
• Trouble sleeping

Symptoms in children

• Slower growth or weight gain
• Frequent urination or bedwetting
• Swelling around the eyes, especially in the morning
• Fussiness or poor appetite

Symptoms in older adults

• Confusion or trouble concentrating
• Loss of energy and muscle strength
• Nausea and vomiting that may be mistaken for stomach problems
• Bone pain or fractures

Causes

Main causes

• Diabetes – high blood sugar can damage kidney blood vessels over time
• High blood pressure – can strain and damage the kidneys' filtering units
• Glomerulonephritis – inflammation of the kidney's filtering units
• Polycystic kidney disease – an inherited condition that causes cysts to form in the kidneys

Risk factors

• Having diabetes, high blood pressure, or heart disease
• Family history of kidney disease
• Age over 60
• Smoking
• Obesity
• Long-term use of certain pain medications (like NSAIDs) without medical supervision

When to see a doctor

See a doctor urgently if:

• If you have sudden shortness of breath, chest pain, or severe swelling.
• If you are unable to urinate for more than 12 hours.

Book a routine appointment if:

• At least once a year if you have diabetes or high blood pressure.
• If you notice swelling, changes in urination, or persistent fatigue.
• Before starting any new treatment that might affect your kidneys.

Diagnosis

Doctors diagnose kidney disease using blood tests, urine tests, imaging scans, and sometimes a kidney biopsy. They measure waste levels in your blood and check for protein or blood in your urine.

Tests that may be done

• Blood creatinine test (eGFR) – estimates how well your kidneys filter waste
• Urine albumin-to-creatinine ratio (UACR) – checks for protein leakage
• Ultrasound or CT scan – looks at the size and structure of your kidneys
• Kidney biopsy – a small sample of kidney tissue is taken to find the cause of damage

What to expect at your appointment

Most tests are painless and done at a clinic or hospital. A blood sample is taken from your arm, and you may be asked to collect urine over 24 hours. For a biopsy, you will be given a numbing medicine and a thin needle to remove a tiny piece of tissue.

Treatment

Treatment focuses on slowing kidney damage, managing symptoms, and preparing for more advanced care if needed. Your doctor will tailor a plan based on the cause and stage of your kidney disease. Important questions to ask include: 'What is my kidney function level?', 'What treatments can slow the disease?', 'Will I need dialysis or a transplant?', and 'What medicines should I avoid?'

Self-care at home

• Monitor your blood pressure and blood sugar at home as directed
• Take all medicines exactly as prescribed
• Avoid smoking and limit alcohol
• Stay active with moderate exercise (like walking) for at least 30 minutes most days
• Track your weight daily to notice sudden fluid changes

Medical treatments

Medical treatments may include medicines to lower blood pressure (such as ACE inhibitors or ARBs), control blood sugar, reduce swelling, and manage mineral and bone problems. If kidney failure occurs, dialysis (a machine that filters your blood) or a kidney transplant may be needed. Your healthcare team will help you understand the options and choose the best one for you.

When is surgery considered?

Surgery is not used for early kidney disease. For advanced disease, a kidney transplant is a major surgery that replaces a failing kidney with a healthy one from a donor. Before surgery, ask: 'What are the risks and benefits of transplant?', 'How long is the recovery?', and 'What lifestyle changes will I need after transplant?'

Living with this condition

Living with kidney disease means regular doctor visits, taking medicines, and watching your diet. Ask your care team: 'How often should I be tested?', 'What numbers should I track?', and 'When should I call you with changes?'

Lifestyle tips

• Follow a kidney-friendly diet low in salt, potassium, and phosphorus (a dietitian can help)
• Drink enough fluids as recommended by your doctor
• Get at least 7–8 hours of sleep each night
• Manage stress with relaxation techniques like deep breathing or gentle yoga

Diet and exercise

A balanced diet for kidney disease often includes fresh fruits and vegetables (but limit high-potassium foods like bananas and potatoes if levels are high), lean protein, and whole grains. Your doctor or dietitian can give you a specific plan. Moderate exercise, like walking or swimming, helps control blood pressure and weight.

Mental health and emotional wellbeing

Coping with a chronic illness can be challenging. You may feel anxious, depressed, or overwhelmed. It is normal. Talk to your healthcare provider about how you feel. They can connect you with a counselor or support group. If you have thoughts of harming yourself, call your local emergency number or a crisis helpline immediately.

Prevention

You can reduce your risk by controlling blood pressure and blood sugar, eating a healthy diet, exercising, not smoking, and limiting medications like NSAIDs. If you already have kidney disease, these steps can slow its progress.

Vaccines

Ask your doctor about vaccines for flu, pneumonia, and hepatitis B, as these infections can be more serious if you have kidney disease.

Screening programmes

If you have diabetes, high blood pressure, or a family history, ask your doctor for a kidney screening blood test (eGFR) and urine test at least once a year.

Complications

If left untreated

• Worsening kidney function leading to kidney failure (end-stage renal disease)
• High blood pressure that is hard to control
• Anemia (low red blood cells causing fatigue and weakness)
• Bone disease from mineral imbalances
• Fluid buildup that can lead to heart problems

Long-term outlook

With early detection and proper care, many people with kidney disease can manage their condition for years and maintain a good quality of life. Treatments like dialysis and transplant can allow people to live active, fulfilling lives even with kidney failure.
