Kidney Disease and Leg Swelling: Causes, Symptoms, and Natural Management
Kidney Disease and Leg Swelling or edema is a symptom of kidney issues that is often ignored. Swelling of the lower legs, feet, and ankles can be the first sign of a problem with kidney function for many people in the US. Learning more about the link between kidney disease and swelling of the lower legs will help you recognize the symptoms early so that you can get the right treatment. In this blog post, we will discuss the causes of swelling due to kidney disease, symptoms to look out for, and home remedies for kidney health using Medilux Ayurveda.
What Is Leg Swelling in Kidney Disease?
The buildup of excess fluid in the body tissues is responsible for the swelling of the legs. Urine is the fluid in the body that filters waste materials from the body. Leg swelling, on the other hand, is caused by the buildup of excess fluid and sodium in the body when the kidneys are not functioning properly.
Fluid retention is one of the most common symptoms of moderate to severe kidney disease, according to the National Kidney Foundation. Patients with pitting edema have swollen legs that can cause tight shoes, ankles, or skin impressions when pressed against the swollen part.
Why Kidney Disease Causes Leg Swelling
Kidney Disease and Leg Swelling is a result of several physiological changes that occur as a result of the malfunctioning of the kidneys:
Fluid Retention
The kidneys are unable to filter excess sodium and water when they are damaged. This results in the accumulation of fluid in the tissues, especially in the lower limbs due to the effect of gravity.
Protein Loss in Urine (Proteinuria)
The kidneys are able to retain proteins in the blood. However, when the kidneys are damaged, proteins are lost in the urine, leading to a reduction in the amount of albumin in the blood. This results in the accumulation of fluid in the tissues, leading to swelling.
Reduced Filtration Rate (Low GFR)
A decreased glomerular filtration rate (GFR) means that fewer wastes and fluids are being removed from the body, contributing to edema and weight gain.
High Blood Pressure
Kidney disease is often associated with hypertension, which damages blood vessels and leads to fluid accumulation in tissues, contributing to swelling.
Common Symptoms of Kidney Disease–Related Leg Swelling
Swelling associated with kidney disease can be gradual or acute. The symptoms of swelling include:
- Swollen legs and feet
- Trouble wearing shoes or socks
- Dents in the skin when pressed (pitting edema)
- Weight gain due to fluid retention
- Fatigue and shortness of breath
- Decreased urine output
When swelling is associated with fatigue, vomiting, and hypertension, it may indicate a decline in kidney function.
Stages of Kidney Disease and Edema Risk
Leg swelling is more common in moderate to advanced stages of kidney disease:
| CKD Stage | Kidney Function | Swelling Risk |
| Stage 1–2 | Mild decline | Rare or minimal |
| Stage 3 | Moderate damage | Occasional swelling |
| Stage 4 | Severe damage | Frequent edema |
| Stage 5 (Kidney Failure) | Very low function | Severe swelling |
Early detection and lifestyle changes can slow disease progression and reduce swelling.
Who Is at Higher Risk?
Certain individuals in the USA are at a higher risk of developing swollen legs due to kidney issues:
- Diabetics
- Individuals with high blood pressure
- Elderly individuals (60+ years)
- Individuals with heart conditions
- Overweight or sedentary individuals
- Individuals with a family history of kidney ailments
- It is essential for high-risk groups to undergo regular kidney function tests.

- Diabetics
- Individuals with high blood pressure
- Elderly individuals (60+ years)
- Individuals with heart conditions
- Overweight or sedentary individuals

It is essential for high-risk groups to undergo regular kidney function tests.
Conventional Treatment Approaches
Some conventional treatments for Kidney Disease and Leg Swelling in the U.S. may include the following:
- Use of diuretics or water pills to remove fluid retention
- Sodium-restricted diet
- Medications to manage blood pressure
- Dialysis for severe kidney failure
While these conventional treatments are effective in managing symptoms, some patients may seek alternative treatments to help their kidneys.
Natural Management of Kidney Disease and Leg Swelling
Although healthcare is a necessity, alternative methods can also help in the proper functioning of kidneys and in the reduction of fluid retention.
Reduce Sodium Intake
Fluid retention can be caused by excessive sodium intake. The American dietary guidelines suggest that sodium intake should be restricted to less than 2,300 mg a day, especially in the case of CKD patients.
Tips:
- Avoid processed and canned foods
- Cut down on fast food and processed snacks
- Use herbs to season instead of salt
Stay Physically Active
Exercise helps improve blood circulation and prevent fluid accumulation in the legs. Walking, yoga, and stretching exercises are very helpful for patients suffering from kidneys.
Elevate Legs Regularly
Raising your legs above the level of your heart for 20-30 minutes daily can help alleviate swelling in the legs by allowing fluid to drain back into the circulation.
Maintain a Kidney-Friendly Diet
A well-balanced renal diet consists of the following:
- Fresh fruits (low potassium varieties if required)
- Whole grains
- Moderate amounts of lean protein
- Healthy fats
- Proper hydration (as directed by the physician)
Manage Blood Pressure and Blood Sugar
Managing diabetes and blood pressure is essential in order to avoid any additional damage to the kidneys and minimize the chances of swelling.
Ayurvedic Perspective on Kidney Disease and Edema
According to Ayurveda, the Kidney Disease and Leg Swelling is linked to an imbalance of Kapha and Vata doshas, as well as the malfunctioning of Mutravaha Srotas (urinary channels). Fluid retention is considered an indication of inefficient metabolism and elimination in the body.
Ayurvedic treatment for kidney problems includes:
- Enhancing kidney cleansing
- Enhancing digestion and metabolism
- Reducing inflammation and fluid retention naturally
At Medilux Ayurveda, herbal treatments are provided to manage the condition naturally and promote kidney health.
Natural Ways to Manage Leg Swelling in Kidney Disease
Limit Sodium in Your Diet
Eating low-sodium foods can help you avoid fluid retention. Cut down on processed foods, soups in cans, fast food, and other high-sodium foods that are popular in the U.S.
Stay Active
Engage in light walking and elevate your legs to help improve blood circulation and alleviate swelling. Avoid sitting for long periods, especially during your working hours.
Drink Fluids in Moderation
Drink fluids in moderation. Too much fluid can exacerbate swelling, but not drinking enough can overwork your kidneys.
Herbal Kidney Support
Some Ayurvedic herbs have been traditionally used to support kidney function and alleviate fluid retention:
- Punarnava (Boerhavia diffusa)
- Gokshura (Tribulus terrestris)
- Varuna (Crataeva nurvala)
These herbs are thought to work by supporting urinary balance and alleviating edema naturally when used properly under expert guidance.
Elevate Legs
Elevating your legs above the level of your heart for 20-30 minutes daily may help alleviate fluid retention.
Maintain Healthy Blood Pressure
Managing high blood pressure is a crucial step in avoiding any additional damage to the kidneys and preventing swelling.
Ayurvedic Perspective on Kidney Disease and Swelling
According to Ayurvedic principles, swelling in the legs due to kidney disorders is caused by an imbalance of “Kapha” and the body’s fluid metabolism (Jal Dhatu).
Medilux Ayurveda’s herbal products are specifically designed to:
- Detoxify the kidneys
- Decrease water retention in the body
- Increase urine production naturally
- Strengthen the kidneys

- Palash and Giloy – Helps in detoxification and boosting immunity
These herbs can help in reducing swelling naturally.
When to Seek Medical Help
If the swelling in the legs is accompanied by the following, it is necessary to seek immediate medical attention:
- Sudden increase in weight
- Chest pain or difficulty in breathing
- Intense fatigue or confusion
- Very low urine output
These symptoms can be an indication of the progression of kidney failure or fluid overload in the heart and lungs.
Preventing Leg Swelling in Kidney Disease
Prevention methods are aimed at preserving kidney function and fluid balance:
- Check kidney function every year
- Keep a healthy weight
- Hydrate appropriately
- Eat a low-sodium renal diet
- Avoid NSAID pain medications
- Control diabetes and hypertension
Lifestyle changes made early can greatly slow the progression of CKD and alleviate symptoms such as swelling.
