kidney complications awareness

Overview

Kidney complications are health problems that happen when your kidneys are damaged or not working as well as they should. Your kidneys filter waste and extra fluid from your blood. When they are injured, waste can build up, leading to serious health issues like heart disease, bone problems, and kidney failure.

Yes, kidney disease is common. Around 1 in 7 adults worldwide has chronic kidney disease, and many don't know it.

Kidney complications can affect anyone, but you are more likely to have problems if you have diabetes, high blood pressure, heart disease, a family history of kidney disease, or are over 60 years old.

Symptoms

Common symptoms

• Feeling more tired than usual
• Swelling in the feet, ankles, or hands
• Changes in urination (foamy, dark, bloody, or very little urine)
• Difficulty sleeping
• Dry, itchy skin
• Poor appetite or metallic taste in the mouth
• Muscle cramps, especially at night

Symptoms in children

• Slow growth or poor weight gain
• Frequent urinary tract infections
• Swelling around the eyes (especially in the morning)
• High blood pressure
• Unusual fussiness or excessive sleepiness

Symptoms in older adults

• Confusion or trouble thinking clearly
• Fatigue and weakness
• Loss of appetite
• New or worse falls
• Urinating less often or more often at night

Causes

Main causes

• Diabetes (high blood sugar damages blood vessels in the kidneys)
• High blood pressure (damages the tiny filters in your kidneys)
• Glomerulonephritis (inflammation of the kidney's filter units)
• Repeated or severe kidney infections
• Kidney stones that block urine flow
• Polycystic kidney disease (an inherited condition with cysts on the kidneys)
• Heavy use of non-steroidal anti-inflammatory drugs (like ibuprofen) over many years

Risk factors

• Having diabetes or high blood pressure
• Being over 60 years old
• Having a family history of kidney failure
• Smoking
• Being overweight or having obesity
• Having heart disease or a history of stroke
• Having an autoimmune condition, such as lupus

When to see a doctor

See a doctor urgently if:

• If you have any of the emergency signs listed above, call your local emergency number right away.
• If you have a fever with back or side pain, go to urgent care or call your doctor the same day.

Book a routine appointment if:

• See your doctor at least once a year for checkups if you have diabetes, high blood pressure, or other risk factors.
• Ask for a simple blood and urine test if you have risk factors or new symptoms.

Diagnosis

Kidney problems are found with simple tests your doctor can order. No special preparation is usually needed. If you have symptoms or risk factors, your doctor will likely recommend blood and urine tests.

Tests that may be done

• Blood test for creatinine and estimated glomerular filtration rate (eGFR) — tells how well your kidneys filter waste
• Urine test for albumin — checks for protein leaking into your urine
• Ultrasound or CT scan of the kidneys — looks at the size and shape of your kidneys, and for stones or blockages
• Blood pressure check — high blood pressure both causes and results from kidney disease

What to expect at your appointment

Your doctor will explain your test results and what they mean. You may need to return for a repeat test to confirm. If problems are found, you will be referred to a kidney specialist (a nephrologist) for more detailed care.

Treatment

Treatment for kidney complications depends on the cause and how far the condition has progressed. The main goals are to protect your kidneys from more damage, treat the underlying cause, and manage symptoms. Many people with kidney disease live long, full lives with the right care.

Self-care at home

• Take all prescribed medications exactly as directed (without skipping doses)
• Check your blood pressure at home and keep a log for your doctor
• Stay well hydrated, but do not exceed 8–10 cups of fluid per day unless your doctor advises otherwise
• Work with a dietitian to reduce salt and processed foods
• Avoid smoking and limit alcohol
• Do not take over-the-counter pain medications (like ibuprofen) for a long time without talking to your doctor

Medical treatments

Treatments may include medications to lower blood pressure and control blood sugar, medicines to reduce protein in the urine, and treatments for anemia or bone problems. Some people may need dialysis, a treatment that filters waste from your blood when your kidneys cannot do the job well. In advanced cases, a kidney transplant may be an option. Your doctor will work with you to choose the best plan for your situation.

When is surgery considered?

Surgery may be needed to remove a large kidney stone that blocks urine flow, to correct a structural problem, or to prepare your body for a kidney transplant (for example, creating a fistula in your arm for dialysis).

Living with this condition

Living with kidney complications means paying attention to your body and staying on top of your treatment. Keep your doctor appointments, take your medicines as prescribed, and monitor for any new symptoms. You may need to learn to manage your salt, protein, and fluid intake — a dietitian can help you design a plan that fits your tastes and needs.

Lifestyle tips

• Follow a kidney-friendly eating plan (often lower in sodium, phosphorus, and potassium)
• Stay physically active with walking, swimming, or other gentle exercise most days
• Get enough sleep and manage stress with relaxation, mindfulness, or talking with friends
• Keep an up-to-date list of your medicines and share it with every doctor you see

Diet and exercise

Eat mostly fresh, whole foods like vegetables, fruits, whole grains, and lean proteins. Limit processed foods, canned soups, and fast food, which are high in salt. Ask your doctor or dietitian about how much protein and fluid are right for you, since too much or too little can be harmful. Walking for 30 minutes a day is safe for most people — check with your doctor before starting a new routine.

Mental health and emotional wellbeing

Learning you have kidney complications can feel overwhelming or scary. It’s normal to feel anxious, sad, or frustrated. Talk openly with your healthcare team and family about how you feel. If you notice persistent sadness, loss of interest, or hopelessness, speak with your doctor. They can connect you with counseling or a peer support group.

Prevention

You cannot always prevent kidney complications, especially if they come from a genetic condition, but you can reduce your risk and slow down a problem that has already started. Managing blood pressure and blood sugar, maintaining a healthy weight, and not smoking are the most powerful steps.

Vaccines

Stay up to date on flu, COVID-19, and pneumonia vaccines. Infection can stress your kidneys, so preventing infections is important. Talk to your doctor about which vaccines are right for you.

Screening programmes

If you have diabetes, high blood pressure, or a family history of kidney disease, get your blood pressure, blood creatinine, and urine protein checked at least once a year. Early changes can be found long before symptoms appear.

Complications

If left untreated

• Kidney failure (end-stage kidney disease), which may require dialysis or transplant
• Heart disease and stroke due to high blood pressure and fluid buildup
• Anemia (low red blood cells) causing severe tiredness
• Bone weakness and fractures due to abnormal calcium and phosphorus levels
• High potassium levels, which can cause dangerous heart rhythms
• Fluid buildup in the lungs (pulmonary edema)

Long-term outlook

A diagnosis of kidney complications is serious, but it is not a cause for despair. With careful follow-up, lifestyle changes, and modern treatments, many people are able to live comfortably for many years. Early detection gives you the best chance to protect your kidneys and your overall health. Your doctors will be with you at every step to manage changes and support your quality of life.
