Are your kidneys OK ? Understanding the Risk Factors for Kidney Disease

Contents

Last updated: 8 October 2026

Kidney Disease is often a silent condition because it can develop slowly and without noticeable symptoms. That is why knowing the risk factors for kidney disease matters so much. The main risk factors for kidney disease are diabetes and high blood pressure, followed by heart disease, obesity, smoking, a family history of kidney failure and being over 60. The Kidneys are the Most Important Organs. Yes, obviously, being Nephrologists we are going to say that! But it’s the truth and nothing but the truth.

They play a Key Role in Filtering Waste, Maintaining Water and Salt Balance, Regulating Blood Pressure, Regulating Sugar Control( Yes you heard it right!), Maintaining Bone Health, keeping your Hemoglobin Normal and the list goes on.. When Kidney Function Starts to Decline, it can lead to serious Health Complications.

The good news is that many cases of Kidney Disease can be prevented or managed, especially if the risk factors are recognized early. We thought it is important to explain how you can tell if you are at risk for Kidney Disease.

Key Takeaways

  • Kidney disease is often silent until a lot of function is lost, so knowing your risk matters more than waiting for symptoms.
  • Diabetes and high blood pressure are the biggest risk factors, followed by heart disease, obesity, smoking and a family history of kidney failure.
  • Age and family history cannot be changed, but they are a strong reason to get screened early.
  • Two simple tests, a blood test for eGFR and a urine test for albumin, can pick up kidney damage years before symptoms.
  • Avoid regular painkillers and unsupervised medicines, keep salt low, and control your sugar and blood pressure to protect your kidneys.

Non-Modifiable Risk Factors for Kidney Disease

Well, as all things in life there are some things we cant really control or change. But being aware helps us to screen for Kidney Disease early and get the right medications to slow it down, and in some cases reverse it.

  1. Age
    As you age, kidney function naturally declines. From middle age onwards, kidney function slowly declines, which may increase the likelihood of kidney disease. It’s more common in people over the age of 60, so older adults should monitor their kidney health more closely. But its not a black and white situation. Many youngsters and children can suffer from kidney disease too.
  2. Family History of Kidney Disease
    Your genetic makeup plays a major role in determining your risk of kidney disease. If you have a family history of chronic kidney disease (CKD), you may be at higher risk of developing the condition yourself. Certain hereditary conditions, like polycystic kidney disease (PKD), also increase the risk. There are genetic tests available now and screening of family members is extremely important.

Modifiable Risk Factors for Kidney Disease

While you can’t change your age or family history, there are several lifestyle-related factors that you can control to lower your risk of kidney disease.

  1. Diabetes
    One of the most significant risk factors for kidney disease is diabetes. High blood sugar levels, especially when poorly controlled over time, can damage the tiny blood vessels in the kidneys. This can lead to kidney damage and, eventually, kidney failure if left untreated. If you have diabetes, it’s important to keep your blood sugar levels well-managed to protect your kidneys. You have to screen your kidneys once in 6 months once you are detected with diabetes.
  2. High Blood Pressure
    High Blood Pressure (hypertension) is another major risk factor for kidney disease. Elevated blood pressure damages the blood vessels in the kidneys, making it difficult for them to filter waste properly. In fact, uncontrolled hypertension is one of the leading causes of kidney failure. Managing your blood pressure through a healthy diet, regular exercise, and medication can significantly reduce the risk of kidney damage.
  3. Obesity
    Being overweight or obese can contribute to both diabetes and high blood pressure, which, in turn, increase your risk of developing kidney disease. Excess body weight also places additional strain on your kidneys, making them work harder. A balanced diet and regular physical activity are key to achieving and maintaining a healthy weight, which can help protect your kidneys.
  4. Smoking
    Smoking is harmful to nearly every part of your body, and your kidneys are no exception. Smoking reduces blood flow to the kidneys and can cause damage to the blood vessels, increasing the risk of kidney disease. Quitting smoking can improve kidney health and overall well-being.
  5. Unhealthy Diet
    A diet high in sodium, unhealthy fats, and processed foods can contribute to high blood pressure and increase the burden on your kidneys. Excessive salt consumption, in particular, can raise blood pressure, which is a risk factor for kidney disease. Eating a well-balanced diet rich in fruits, vegetables, lean proteins, and whole grains helps maintain kidney function and overall health. Talk to your physician and nephrologist to improve your diet.
  6. Excessive Alcohol Consumption
    The WHO says no level of alcohol is completely safe for health, and heavy drinking can lead to kidney damage over time. Heavy drinking can raise blood pressure and cause dehydration, which can strain the kidneys. Limiting alcohol intake can help protect kidney function.
  7. Overuse of Painkillers and over the counter medications.
    Common over-the-counter pain medications can be harmful to the kidneys if used excessively or over a long period without proper advice from a doctor. These medications can damage kidney tissue and impair their function, especially when taken in high doses or combined with other medications. For that matter, any medicine you ingest whether its allopathic or native medications should be done under strict supervision. Always follow the recommended dosages and consult a doctor if you need pain relief regularly.

Other Risk Factors to Be Aware Of

In addition to the primary risk factors, there are a few other conditions that can increase your chances of developing kidney disease.

Heart Disease

If you have cardiovascular problems, you’re at a higher risk for kidney disease due to the shared blood vessel structures that both systems rely on.

Recurrent Urinary Tract Infections (UTIs)

Frequent or untreated UTIs can lead to kidney damage if the infection spreads to the kidneys.

Autoimmune Diseases

Conditions such as lupus or vasculitis can cause inflammation in the kidneys and increase the risk of kidney damage.

A Past Episode of Acute Kidney Injury

A past episode of acute kidney injury (AKI), a sudden drop in kidney function after severe dehydration, a serious infection, certain medicines or a major operation, raises the risk of chronic kidney disease later, even when the kidneys seem to recover. If you have had AKI, ask your doctor to recheck your kidney function in the months that follow.

Kidney Stones That Keep Coming Back

Kidney stones that keep coming back can block the flow of urine and damage the kidneys over time, so repeated stones are a reason for kidney tests and a plan to prevent new ones. Hot summers and outdoor work make it easy to become dehydrated, so drink enough water through the day unless your doctor has set a fluid limit.

Being of South Asian Origin

Being of South Asian origin is a risk factor in its own right: the NHS notes that chronic kidney disease is more common in people of south Asian origin. Diabetes and high blood pressure are also common in India and often go unnoticed for years, so regular kidney tests matter even if you feel well.

Early Warning Signs of Kidney Disease

Most people with early kidney disease feel completely well. As kidney function falls, these signs may appear. If you notice any of them, especially with one of the risk factors above, see a doctor:

  • Swelling of the feet, ankles, face or around the eyes.
  • Foamy or frothy urine, which can mean protein is leaking.
  • Blood in the urine, or urine that looks dark or cola-coloured.
  • Passing urine more often, especially at night, or passing much less than usual.
  • Tiredness, poor appetite, nausea or itching that does not go away.
  • High blood pressure that is new or hard to control.

Seek emergency care and call 108 for an ambulance if you pass very little or no urine, become severely breathless, or feel confused or very drowsy.

Kidney Tests: Who Should Get Checked and How Often

Because the early stages are silent, testing is the only reliable way to know. The US National Institute of Diabetes and Digestive and Kidney Diseases advises kidney checks for people with diabetes, high blood pressure, heart disease or a family history of kidney failure. Two simple tests do most of the work:

TestWhat it measuresWhat to look for
eGFR (blood test)How well the kidneys filter waste, worked out from your creatinine level, age and sexA GFR of 60 or more is in the normal range; less than 60 may mean kidney disease
Urine albumin-to-creatinine ratio (UACR)Whether protein (albumin) is leaking into the urine30 mg/g or less is normal; more than 30 mg/g may be a sign of kidney damage
If you haveHow often to check
DiabetesEvery 6 months, as our nephrologists advise above, and never less than once a year
High blood pressureAs often as your doctor advises, usually at least once a year
Heart disease or heart failureAs often as your doctor advises
A family history of kidney failure or polycystic kidney diseaseAsk your doctor about screening, including for other family members
Regular use of painkillers or other long-term medicinesAsk your doctor whether a kidney check is needed

A single abnormal result is usually repeated to confirm it, because readings can vary from day to day.

Simple Steps to Protect Your Kidneys

  • Keep blood sugar and blood pressure in the target range your doctor sets, and take your medicines regularly.
  • Cut down on salt. Go easy on pickles, papad, salted snacks and packaged foods.
  • Do not self-medicate with painkillers, or with allopathic or native remedies, without advice from your doctor.
  • Stay active and keep a healthy weight, with at least a brisk daily walk if your doctor agrees.
  • Stop smoking and limit alcohol.
  • Drink enough water for the weather and your activity, unless your doctor has asked you to limit fluids.

Get Your Kidneys Checked

Remember, when detected early, most kidney diseases are reversible or manageable.

Frequently Asked Questions

Kidney disease often has no symptoms in the early stages. However, signs like swelling in the legs, frequent urination, fatigue, and high blood pressure may indicate kidney issues. A simple blood and urine test can help detect kidney problems early.

Not necessarily. While genetics play a role, lifestyle choices like maintaining a healthy diet, managing blood pressure and blood sugar, and staying hydrated can help reduce your risk.

If you have diabetes, you should get your kidneys checked every six months to detect any early signs of damage. International diabetes guidelines set a minimum of one kidney check a year, with a blood test for eGFR and a urine test for albumin.

Chronic kidney disease usually cannot be cured, but finding it early and treating the cause can slow it down or stop it from getting worse. Some kidney problems, such as acute kidney injury after dehydration or a medicine, can recover fully with prompt treatment. Advanced stages may require more intensive treatment, such as dialysis or a transplant.

Staying hydrated supports kidney function, but excessive water intake won’t prevent kidney disease caused by other factors like diabetes or high blood pressure. A balanced water intake based on your doctor’s advice is best.

Early signs may include fatigue, swelling in the ankles, changes in urination, foamy urine, or high blood pressure. However, kidney disease often develops silently, so regular checkups are the only reliable way to catch it early.

The main risk factors for kidney disease are diabetes and high blood pressure. Others include heart disease, obesity, smoking, a family history of kidney failure, older age, and long-term use of painkillers without medical advice. Having even one of these is a good reason to ask your doctor for a blood test for eGFR and a urine test for albumin.

Yes. Common over-the-counter painkillers, especially anti-inflammatory medicines, can harm the kidneys when taken often, for a long time or with certain other medicines. The risk is higher if you already have kidney disease, diabetes, heart failure or dehydration. If you need pain relief regularly, ask your doctor which option is safest for you.

Yes. Over time, high blood pressure damages the small blood vessels in the kidneys, so they filter waste less well. Damaged kidneys can in turn push blood pressure higher, creating a cycle. Keeping your blood pressure in the range your doctor advises, cutting salt and taking medicines regularly helps protect your kidneys.

You can change or control diabetes, high blood pressure, obesity, smoking, heavy drinking, a high-salt diet and regular use of painkillers without advice. You cannot change your age, family history or ethnic background, but knowing about them is a good reason to get your kidneys tested early and more often.

Yes. People of South Asian origin have a higher risk of chronic kidney disease, as the NHS notes. Diabetes and high blood pressure, the two biggest causes, are common in India and often go unnoticed for years. If you have any risk factor, ask your doctor about an eGFR blood test and a urine albumin test.

Yes. Having had acute kidney injury, a sudden drop in kidney function from dehydration, infection, certain medicines or major surgery, raises the chance of chronic kidney disease later, even if the kidneys seemed to recover. Ask your doctor to recheck your creatinine, eGFR and urine albumin in the months after the episode.
