    This source-checked educational guide completed clinical review before public release. It supports understanding and care-team questions; it does not replace individualized diagnosis, treatment, medication, or emergency instructions.

    Three-minute entry point

    Choose what you need right now

    The detailed guide remains below. These four paths move directly to the needs patients and caregivers most often have after diagnosis or discharge.

    Understand the diagnosis

    Start with the 30-second explanation and the most useful treatment paths.

    Understand the medicines

    Learn the job of each treatment group before trying to memorize names.

    Know what to do each day

    Turn the plan into specific monitoring, access, follow-up, and barrier checks.

    Know when to get help

    Separate emergency symptoms from changes that need a prompt care-team call.

    Start here

    What kidney failure (ESKD or ESRD) actually means

    One usable mental model before the tests, medicine names, and procedures.

    The 30-second explanation

    Kidney failure means the kidneys have lost most of their ability to remove waste and extra fluid and to help regulate salts, acid, blood pressure, red-blood-cell production, and bone-mineral balance. Treatment choices include hemodialysis, peritoneal dialysis, kidney transplant, and comprehensive conservative care without dialysis or transplant. The right plan depends on symptoms, laboratory problems, daily life, other illnesses, goals, support, and informed preference—not one eGFR number alone.

    A sentence you can repeat

    My kidneys can no longer perform enough of their normal work. My care plan must explain whether I am preparing for dialysis, transplant, or conservative care and how we will manage fluid, blood chemistry, medicines, and symptoms.

    ESKD

    End-stage kidney disease: a commonly preferred clinical term for kidney failure requiring or approaching long-term kidney-replacement decisions.

    ESRD

    End-stage renal disease: an older term still used in U.S. law, insurance, and Medicare administration, often referring to kidney failure treated with dialysis or transplant.

    Uremia

    Symptoms and organ effects caused by the buildup of waste and other changes when kidney function is insufficient.

    Dry weight

    A dialysis-team estimate of body weight without excess fluid. It is individualized and adjusted over time rather than copied from a scale target online.

    Treatment paths

    Kidney failure care is a set of choices—not one automatic route

    Each option changes schedule, independence, access, diet, medicines, travel, caregiver work, and medical risk.

    Blood is filtered through a machine

    Hemodialysis

    Blood travels through a dialyzer outside the body and returns through a vascular access. Treatment may occur in a center or at home on different schedules.

    Why it matters: Access type, treatment frequency, transport, recovery time, blood pressure, fluid removal, work schedule, and home support affect the experience and safety.

    The abdominal lining filters inside the body

    Peritoneal dialysis

    Dialysis solution enters the abdomen through a catheter, collects waste and fluid, and is drained in manual daytime exchanges or by a nighttime cycler.

    Why it matters: It offers home flexibility but requires daily sterile technique, supply storage, catheter care, and rapid response to cloudy fluid or abdominal pain.

    A donor kidney—or active care without replacement therapy

    Transplant or conservative care

    Transplant can provide the most complete kidney replacement but requires surgery and lifelong anti-rejection medicine. Conservative care treats symptoms and complications without dialysis or transplant.

    Why it matters: Both require early goals-of-care discussion. Transplant evaluation can begin before dialysis; conservative care should include symptom, family, advance-care, and crisis planning.

    A person may move between treatments, try one modality, receive a transplant after dialysis, return to dialysis after transplant failure, or choose to stop dialysis after an informed goals-of-care process. Shared decisions should be revisited as health and priorities change.
    Possible causes and contributors

    What can contribute to this diagnosis

    These categories help organize questions; they do not identify one reader’s cause.

    Diabetes

    Long-term high blood glucose can damage kidney filters and is a leading cause of kidney failure.

    High blood pressure and vascular disease

    Pressure and blood-vessel injury can progressively reduce filtering function.

    Glomerular and immune disease

    Inflammation or scarring of kidney filters can cause protein loss and progressive failure.

    Inherited and cystic disease

    Polycystic kidney disease, Alport syndrome, and other inherited disorders may progress over years.

    Obstruction, reflux, or recurrent injury

    Urinary blockage, congenital abnormalities, repeated infections, stones, or recurrent AKI can contribute.

    Medication, toxin, or systemic disease

    Selected exposures, autoimmune disease, heart disease, liver disease, cancer treatment, and other systemic illness may damage kidneys.

    Important boundary: Kidney failure often reflects years of disease and more than one contributor. Ask what diagnosis caused it, whether that disease remains active, and whether family members need screening.
    Evaluation

    What each common test is trying to answer

    A test is easier to understand when the clinical question comes first.

    Test or evaluation

    Creatinine, eGFR, and urine albumin

    Question it helps answer

    How much filtering function remains, how fast is it changing, and how much kidney damage or protein leakage is present?

    What to know

    eGFR supports staging and planning, but dialysis initiation should not be based on one isolated value without symptoms, complications, and clinical assessment.

    Test or evaluation

    Potassium, bicarbonate, sodium, and fluid assessment

    Question it helps answer

    Are dangerous potassium, acid, salt, blood-pressure, swelling, or breathing problems developing?

    What to know

    The safest diet, medicine, and dialysis prescription depends on repeated values, urine output, heart function, and treatment modality.

    Test or evaluation

    Hemoglobin and iron studies

    Question it helps answer

    Is kidney-related anemia or iron deficiency contributing to fatigue, breathlessness, or treatment needs?

    What to know

    Blood loss, inflammation, nutrition, and other conditions also cause anemia. ESA treatment uses individualized hemoglobin goals and clot-risk assessment.

    Test or evaluation

    Calcium, phosphorus, parathyroid hormone, and vitamin D

    Question it helps answer

    Is kidney-related mineral and bone disease affecting bones, blood vessels, itching, or treatment?

    What to know

    These values interact. Treating one number without the others can create harm, so binders and hormone-directed medicines require coordinated monitoring.

    Test or evaluation

    Dialysis adequacy and access assessment

    Question it helps answer

    Is dialysis removing enough waste and fluid, and is the fistula, graft, catheter, or PD catheter working safely?

    What to know

    Adequacy includes laboratory measures, symptoms, volume control, nutrition, access function, and whether prescribed treatments are completed.

    Test or evaluation

    Transplant evaluation

    Question it helps answer

    Is transplantation medically and practically appropriate, and what testing, cancer screening, dental care, vaccination, cardiac evaluation, social support, and financial planning are required?

    What to know

    Referral can occur before dialysis. Evaluation and listing are processes; referral does not guarantee listing, and a denial should include reasons and possible next steps.

    Treatment goals

    Start with what treatment is trying to accomplish

    The medicine and procedure list makes more sense after the goals are clear.

    Control fluid and chemistry

    Prevent dangerous potassium, acid, salt, fluid, and blood-pressure complications.

    Reduce symptoms and preserve function

    Treat nausea, itching, fatigue, sleep problems, anemia, bone disease, neuropathy, and nutrition decline.

    Choose and prepare a treatment path

    Create access, train for home therapy, complete transplant evaluation, or build a conservative-care plan before crisis.

    Protect access and prevent infection

    Maintain vascular or peritoneal access and respond rapidly to infection, clotting, bleeding, or poor flow.

    Align treatment with life goals

    Consider work, transportation, housing, caregiving, travel, symptom burden, prognosis, and the patient’s values.

    Treatment framework: NIDDK identifies four treatment choices: hemodialysis, peritoneal dialysis, kidney transplant, and conservative management. Learning early allows safer access planning and reduces crisis-start dialysis through a temporary catheter.
    Medication decoder

    Understand the job before memorizing the name

    Each card separates purpose, examples, monitoring, questions, and the medication boundary.

    Medication purpose card

    Phosphate binders

    Common language: Medicines taken with food to reduce phosphorus absorption

    The job: Bind phosphorus from food in the digestive tract so less enters the blood.

    Common examples

    Calcium-based bindersSevelamerLanthanumIron-based binders

    Why it may be used

    High phosphorus and related parathyroid changes contribute to bone and vascular complications. The binder choice depends on calcium, iron, pill burden, bowel effects, and other factors.

    What the team may monitor

    • Phosphorus and calcium
    • Parathyroid hormone
    • Constipation or GI effects
    • Timing with meals and other medicines
    • Affordability and pill burden

    Questions to ask

    • Which meals or snacks require it?
    • What if I skip a meal?
    • Can it interfere with other medicine?
    • How will we know it is working?
    Medication boundary: Binder timing and dose are prescription-specific. Do not take extra tablets for a high-phosphorus meal or substitute products without the dialysis or kidney team.
    Medication purpose card

    Iron and erythropoiesis-stimulating treatment

    Common language: Treatment that helps rebuild red blood cells

    The job: Replace iron and stimulate red-blood-cell production when kidney failure contributes to anemia.

    Common examples

    Oral or IV ironEpoetin alfaDarbepoetin alfa and related ESA therapy

    Why it may be used

    Damaged kidneys produce less erythropoietin. Treatment aims to reduce symptoms and transfusion need while avoiding excessive hemoglobin and clot risk.

    What the team may monitor

    • Hemoglobin trend
    • Iron stores
    • Blood pressure
    • Clotting, stroke, and access risk
    • Blood loss and other anemia causes

    Questions to ask

    • Is my anemia from kidney disease, iron deficiency, bleeding, or several causes?
    • What is the hemoglobin plan?
    • Where will treatment be given?
    • Which symptoms require a call?
    Medication boundary: ESA and IV iron doses are adjusted from repeated labs and risk. Do not add iron or change treatment because of fatigue alone.
    Medication purpose card

    Vitamin D, calcimimetics, and mineral-bone treatment

    Common language: Medicines that manage parathyroid and bone chemistry

    The job: Manage parathyroid hormone, calcium, phosphorus, and bone-mineral complications.

    Common examples

    Active vitamin D analoguesCinacalcet or etelcalcetideOther clinician-selected therapy

    Why it may be used

    Kidney failure disrupts vitamin D activation and mineral balance, causing secondary hyperparathyroidism and bone or vascular effects.

    What the team may monitor

    • Calcium, phosphorus, and PTH together
    • Nausea or low calcium
    • Bone symptoms
    • Treatment route and dialysis timing

    Questions to ask

    • Which value is this treating?
    • Could it lower calcium?
    • Is it given at dialysis or at home?
    • When are labs repeated?
    Medication boundary: Do not start calcium, vitamin D, magnesium, or phosphorus supplements without the kidney team. Over-the-counter doses can conflict with the dialysis chemistry plan.
    Medication purpose card

    Potassium, acid, blood-pressure, and fluid medicines

    Common language: Medicines that help control the chemistry between treatments

    The job: Reduce dangerous buildup or manage blood pressure and remaining kidney function between treatments.

    Common examples

    Potassium binders in selected patientsBicarbonate before dialysis in selected CKDDiuretics when urine output remainsBlood-pressure and heart medicines

    Why it may be used

    The need depends on treatment modality, urine output, heart function, dialysis prescription, potassium, bicarbonate, and symptoms.

    What the team may monitor

    • Potassium and bicarbonate
    • Blood pressure and heart rate
    • Weight and fluid status
    • Residual urine output
    • Interaction with dialysis timing

    Questions to ask

    • Should I take this before dialysis?
    • What happens on treatment days?
    • Which reading or symptom changes the plan?
    • What should I do if vomiting prevents a dose?
    Medication boundary: Do not skip heart or blood-pressure medicine before dialysis unless the unit or prescriber gave a specific written plan. Do not change fluid or potassium intake from a generic handout.
    Medication purpose card

    Kidney-dose medication review

    Common language: Making every prescription fit kidney failure and dialysis

    The job: Prevent drug accumulation, undertreatment, interactions, and unsafe timing around dialysis.

    Common examples

    AntibioticsDiabetes medicines and insulinPain medicinesAnticoagulantsGabapentin and other kidney-cleared medicines

    Why it may be used

    Kidney failure and dialysis can change medicine clearance. Some drugs are removed during treatment and others are not.

    What the team may monitor

    • Dose and timing by modality
    • Sedation, falls, low glucose, bleeding, or toxicity
    • Dialysis removal
    • Refill and prescriber coordination

    Questions to ask

    • Was this dose reviewed for my dialysis type?
    • Is it taken before or after treatment?
    • Who owns refills?
    • Which over-the-counter pain and cold medicines are safe?
    Medication boundary: Every prescriber and pharmacist should know the current dialysis modality and schedule. Do not use another patient’s dose or a pre-dialysis medication list without reconciliation.
    Procedures and supportive care

    Some problems require a device, procedure, operation, or specialist pathway

    The care team determines candidacy and timing.

    AV fistula or graft

    A surgeon connects an artery and vein, directly or through a graft, to create durable hemodialysis access. The access must be checked for its usual vibration and protected from pressure, blood draws, and blood-pressure cuffs as instructed.

    Hemodialysis catheter

    A large central-vein catheter can provide immediate access but carries substantial infection and clot risk. Dressing, cap, shower, and emergency instructions must be explicit.

    Peritoneal dialysis catheter

    A tube in the abdomen allows exchanges. Sterile technique and rapid response to cloudy effluent, abdominal pain, fever, or drainage problems are essential.

    Kidney transplant

    A donor kidney provides the most complete replacement of kidney function but requires surgery, infection and rejection monitoring, and lifelong immunosuppression.

    Daily management

    The practical work between appointments

    A short operating plan is easier to use than a long lifestyle paragraph.

    1

    Complete every prescribed treatment

    Missed or shortened dialysis can allow dangerous fluid, potassium, acid, and waste buildup. Contact the unit before a missed session rather than silently skipping.

    2

    Protect the access

    Follow the exact fistula, graft, catheter, or PD-catheter instructions. Know how the access normally feels, looks, and drains.

    3

    Use the personal nutrition and fluid plan

    Potassium, phosphorus, sodium, protein, calories, and fluid needs differ by modality, urine output, labs, diabetes, body size, and nutrition status. Work with the renal dietitian.

    4

    Reconcile medicines at every transition

    Hospital, dialysis-unit, transplant, primary-care, and specialist lists should agree on dose, timing, and treatment-day instructions.

    5

    Track the measurements the team requests

    Weights, blood pressure, glucose, temperature, urine, edema, and PD effluent may be useful when the team defines the method and action threshold.

    6

    Plan transportation, supplies, and backup

    Know how treatment continues during storms, travel, power loss, supply delay, hospitalization, or caregiver illness.

    Action plan

    Separate emergencies from changes that need a prompt call

    The patient’s written plan controls; these categories organize the conversation.

    Get emergency help now

    Call 911 for severe breathing, heart, neurologic, bleeding, or access emergencies.

    • Severe shortness of breath, blue/gray lips, gasping, or inability to lie down
    • Chest pressure, collapse, fainting, seizure, new confusion, or stroke symptoms
    • Uncontrolled bleeding from a fistula or graft
    • A dialysis catheter is pulled out or air entry is suspected
    • Severe weakness or a dangerous-feeling irregular heartbeat that could reflect high potassium

    Verify: Apply the dialysis unit’s taught pressure method for access bleeding while emergency help is activated. Do not clamp, replace, or manipulate a dislodged catheter unless trained and explicitly directed.

    Contact the dialysis or kidney team promptly

    Use the unit’s after-hours route for infection, access failure, treatment interruption, or worsening fluid and uremic symptoms.

    • Fever, chills, redness, warmth, pus, or pain around any dialysis access
    • Cloudy PD drainage, new abdominal pain, fever, or difficulty draining
    • The fistula or graft no longer has its usual vibration or sound
    • Rapid weight gain, increasing swelling, worsening breathlessness, repeated vomiting, confusion, severe itching, or poor intake
    • A missed or shortened dialysis treatment
    • Medication lists conflict or a new medicine was not reviewed for dialysis
    • Supplies, transportation, power, or caregiver support will interrupt treatment

    Verify: Dialysis units should provide a 24-hour contact route. Do not wait for the next routine treatment when infection or access failure is possible.

    Follow the kidney-failure treatment plan

    Use the modality-specific plan to preserve function and quality of life.

    • Attend and complete treatments
    • Protect and inspect access
    • Follow the individualized food and fluid plan
    • Take medicines at the correct treatment-day times
    • Complete monthly and specialist testing
    • Keep transplant or conservative-care planning current

    Verify: Stable symptoms do not guarantee potassium, phosphorus, fluid, anemia, or dialysis adequacy is controlled; scheduled testing remains necessary.

    Prepare and confirm

    Questions and teach-back

    Questions to take to the care team

    1. 1What caused my kidney failure, and is the underlying disease still active?
    2. 2Which options—home or in-center hemodialysis, peritoneal dialysis, transplant, and conservative care—are medically available to me?
    3. 3What symptoms or laboratory problems would determine when dialysis starts or changes?
    4. 4What access do I have or need, and how do I protect it and recognize failure or infection?
    5. 5What are my exact fluid, sodium, potassium, phosphorus, protein, and treatment-day medicine instructions?
    6. 6Am I eligible for transplant referral, and what steps or barriers remain?
    7. 7What is the plan if transportation, supplies, power, weather, or caregiving interrupts treatment?
    8. 8Who helps with Medicare ESRD coverage, employment, disability, transportation, home supplies, and advance-care planning?

    Teach-back check

    A useful introduction is: “I want to make sure I explained this clearly. Please show me or tell me what you will do when you are home.”

    • I can explain that kidney failure affects fluid, chemistry, blood, bone, and waste removal—not only creatinine.
    • I can name the treatment path I chose or am evaluating and why it fits my goals.
    • I can identify my access and demonstrate the safety steps I was taught.
    • I know my personalized food, fluid, and treatment-day medicine plan rather than copying generic limits.
    • I can recognize access bleeding, infection, cloudy PD fluid, severe breathing difficulty, and high-potassium warning symptoms.
    • I know the dialysis, transplant, conservative-care, social-work, and after-hours contacts that own my plan.
