Kidney failure — also called renal failure or acute kidney injury (AKI) — occurs when the kidneys suddenly stop working properly. This condition can be life-threatening and often develops quickly in response to dehydration, severe vomiting, infections, medications, or underlying illnesses.
There is growing concern about kidney failure and kidney injury in patients taking GLP-1 drugs, including Ozempic, Wegovy, Mounjaro, and Rybelsus, especially when severe gastrointestinal side effects lead to dehydration.
This page explains everything patients need to know about kidney failure, including symptoms, causes, diagnosis, treatment, and how GLP-1 drugs may contribute.
What Is Kidney Failure?
Kidney failure happens when the kidneys can no longer filter waste, balance fluids, or maintain essential electrolytes. It can occur:
- suddenly (acute kidney injury)
- gradually (chronic kidney disease progressing to kidney failure)
Both forms require prompt medical attention.
Symptoms of Kidney Failure
Symptoms can appear quickly and may worsen over hours or days.
Early Symptoms
- Fatigue
- Weakness
- Headache
- Loss of appetite
- Nausea or vomiting
Fluid & Urinary Symptoms
- Decreased urination
- Foamy, dark, or bloody urine
- Swelling of legs, ankles, or face
- Sudden weight gain or loss
Severe Symptoms (Medical Emergency)
- Difficulty breathing
- Chest pain
- Confusion
- Seizures
- No urine output
- Irregular heartbeat
- Severe dehydration
Seek immediate medical care if severe symptoms occur.
Causes of Kidney Failure
Common causes include:
Dehydration
Severe vomiting, diarrhea, or reduced fluid intake can cause rapid kidney decline.
Infections or Sepsis
Medications
Certain drugs stress the kidneys or lead to dehydration. GLP-1 drugs are increasingly implicated (details below).
Uncontrolled Diabetes or High Blood Pressure
Obstructed Urinary Tract
Autoimmune Disease
Prolonged NSAID or diuretic use
GLP-1 Drugs and Kidney Failure
GLP-1 medications — particularly Ozempic, Wegovy, Mounjaro, and Rybelsus — are associated with acute kidney injury, mostly due to severe gastrointestinal side effects.
How GLP-1 Drugs May Cause Kidney Injury
- Severe Vomiting and Diarrhea
→ Dehydration reduces kidney blood flow - Inability to Eat or Drink
→ Leads to electrolyte imbalance - Prolonged GI Distress
→ Ongoing dehydration over weeks/months - Drug-Induced Kidney Stress
→ Some patients experience direct renal decline
Risk Is Significantly Higher in patients who:
- have underlying kidney disease
- are older adults
- take diuretics, ACE inhibitors, or NSAIDs
- experience persistent nausea/vomiting
- use GLP-1 drugs for rapid weight loss

How Doctors Diagnose Kidney Failure
Diagnosis may involve:
- Blood Tests
-
- Elevated creatinine
- High BUN
- Low eGFR
- Electrolyte abnormalities (potassium, sodium)
- Urine Tests
-
- Protein in urine
- Blood in urine
- Concentration of urine (specific gravity)
- Infection markers
- Imaging
-
- Kidney ultrasound
- CT scan if obstruction suspected
- Symptom + Medication History
Doctors look for:
- dehydration history
- GLP-1 use
- vomiting frequency
- timing of renal decline
Treatment for Kidney Failure
Treatment depends on severity:
Mild to Moderate AKI
- IV fluids
- Stopping the offending medication (doctor-guided)
- Electrolyte correction
- Monitoring kidney function daily
- Anti-nausea treatment
Severe Kidney Failure
- Hospitalization
- Temporary dialysis
- Treatment for underlying causes
- Long-term nephrology care
Chronic Kidney Decline
- Lifestyle + diet changes
- Blood pressure and glucose control
- Ongoing kidney function monitoring
Can Kidney Failure Be Permanent?
Yes. Even a single episode of untreated acute kidney injury can lead to:
- permanent decrease in eGFR
- progression to chronic kidney disease (CKD)
- long-term dialysis dependence
- increased cardiovascular risk
- reduced lifespan
Patients using GLP-1 drugs who are dehydrated for long periods have a significantly elevated risk of permanent kidney decline.
When to Seek Emergency Care
Go to the ER immediately if you experience:
- inability to urinate
- repeated vomiting
- swelling in legs or face
- dizziness or fainting
- confusion
- chest pain
- sudden weight changes
These are signs of potentially life-threatening kidney dysfunction.
Legal Rights: Kidney Failure Linked to GLP-1 Drugs
Patients who developed kidney injury or kidney failure after taking Ozempic, Wegovy, Mounjaro, or Rybelsus may be eligible for financial compensation.
You may qualify if you:
- were diagnosed with acute kidney injury
- were hospitalized
- required IV fluids or dialysis
- suffered long-term kidney impairment
- missed work or income
- developed chronic kidney disease
- experienced dehydration-related renal failure
Compensation may include:
- medical bills
- future nephrology care
- lost income
- pain and suffering
- reduced quality of life damages

Kidney failure is a serious and sometimes permanent condition that can occur suddenly, especially when patients using GLP-1 drugs develop severe nausea, vomiting, or dehydration. Early recognition and treatment are critical. If a GLP-1 drug contributed to your kidney injury, you may have both medical and legal options to pursue.
