Did you know that 55 to 60 percent of your body weight is water? Water flows throughout your body from one area to another. It is present inside and outside of your cells and it keeps your tissues moist. Your bones, joints, spinal cord and brain need water, too. (1) But sometimes too much water can build up in your tissues, leading to swelling in your arms and legs. This is called peripheral edema. It’s caused by several factors that vary in seriousness. For some people, a peripheral edema is only temporary and will go away on its own. But for others, it’s a serious issue that’s brought on by a severe, sometimes life-threatening health condition.
It certainly helps to be aware of the symptoms of pitting versus non-pitting edema and how these conditions differ in seriousness. It’s also good to know that there are natural ways to relieve swelling that’s due to water retention. Some herbs work as natural diuretics. Essential oils help to reduce inflammation. Dietary changes can balance the sodium levels in your body, helping you to avoid an electrolyte imbalance.
What Is Peripheral Edema?
Peripheral edema means swelling in your arms and legs. This happens when fluid gathers in your tissues and causes a heavy, swollen and even painful area in the body.
Your body works to make sure that you maintain proper water levels in your cells. It naturally balances water intake and water loss. It works to keep the total amount of water and electrolytes in the blood constant. However, a number of health conditions or situations can cause too much fluid to collect in the tissues and cause noticeable swelling. When the capillaries in your blood vessels begin to leak fluids into your tissues, this causes puffiness and skin tightness, usually in your lower limbs because there’s more pressure on these areas.
Peripheral Edema Signs & Symptoms
The symptoms of peripheral edema depend on the cause of the condition. You will generally notice a swollen area that is stretching the skin and can feel warm to the touch. You may notice that the swelling depends on gravity. So it may appear more serious when you are standing than if you have the area elevated.
There’s a difference between pitting and non-pitting edema. If you apply pressure to the swollen area and your finger leaves an indentation, you have pitting edema. Water retention from too much sodium in the body, standing or sitting for too long, or pressure from your body weight usually causes it. Non-pitting edema, on the other hand, does not leave a mark when you press your finger into it. This can be a more serious condition caused by issues with the heart, lungs, liver or kidneys.
Generally, the most common signs and symptoms of peripheral edema include (2):
- a full or heavy feeling in your arm or leg
- swelling and puffiness, leaving a dent with your finger when you press on the area (which is called “pitting”)
- skin that feels tight and warm
- immobility or difficulty moving joints around the affected area
- pain and tension around the affected area
- a feeling of pressure around the affected area, which can be related to pressure on the veins in your legs
- when shoes, clothing or jewelry becomes tight around the swollen area
Peripheral Edema Causes & Risk Factors
A number of health conditions or situations can cause edema. Sometimes the cause is a harmless case of water retention. But it can also result from a chronic, serious condition that needs to be treated immediately. Here’s a breakdown of the possible peripheral edema causes and risk factors:
- Water retention: When the body holds on to or stores water and it builds up in the tissues, this causes temporary swelling in the hands, ankles, feet and face. This can happen when you consume too much sodium. The sodium holds on to water and keeps it in the body. Water retention is also caused by sitting or standing in one position for too long and hormone changes during a women’s monthly period or pregnancy. When a woman is pregnant, her uterus puts pressure on the major blood vessel that’s responsible for returning blood to the heart from the legs. This pressure can allow fluids to get into her tissues, causing swelling in the legs, ankles and feet. (3)
- Inflammation: Inflammation in your tissues may cause swelling in your legs. Inflammation may be a response to allergies, trauma (like a broken bone or sprained ankle), an infection or wound in the leg, arthritis, gout or cellulitis.
- Certain medications: Certain drugs can cause edema because they cause the body’s sodium and water levels to become unbalanced, or they contribute to renal dysfunction. Medications that may cause this issue include NSAIDs (such as ibuprofen or naproxen), insulin, steroid therapy and drugs for high blood pressure. (4)
- Low protein levels in the blood: Fluid leaks out of your blood vessels more easily when there isn’t enough of the protein called albumin (protein that is made by the liver) in your blood. Malnutrition or health conditions that affect how much protein the body produces, like liver and kidney diseases can cause low protein levels in your blood. (5)
- Problems with your veins: When your veins aren’t able to transport enough blood to the feet and then back to the heart — which is called venous insufficiency — your ankles and feet become swollen. Blood gathers in your legs, forcing fluid out of your blood vessels and into the surrounding tissue. This is the most common cause of leg swelling among people over 50 years old, especially in women. (6) Edema can be a sign of thrombosis. This develops as a result of slow-flowing blood and causes a blood clot. Peripheral edema can also be caused by varicose veins. These occur when blood pools in the legs or when blood flow slows down. (7)
- Kidney diseases: When the kidneys aren’t able to remove enough sodium and water from the body, this creates pressure on your blood vessels and can lead to peripheral edema. (8)
- Congestive heart failure: If the heart becomes too weak to pump blood around the body, it will gather in front of the heart and put pressure on your veins. This can cause fluid to seep out into the surrounding tissue. This leaking fluid leads to swelling in the legs or in the abdomen.
- Lung conditions: If pressure in the lungs and heart gets very high, which can happen when your body is reacting to certain medical conditions, this can cause the legs and feet to swell. This can happen as a result of serious lung conditions like emphysema or pulmonary fibrosis. Or it can occur if you have congestive heart failure and your heart isn’t strong enough to pump the blood that’s returning from your lungs. Since the heart, lung, kidneys and brain all work together to regulate fluid levels in the body, when one organ is forced to work harder as a result of a medical condition, hormones are often released to either retain or provide more fluids. Fluid buildup in the lungs is called pulmonary edema. This means water collects in the air sacs of the lungs. Pulmonary edema can make it very difficult to breathe. (9)
Aside from peripheral edema that develops in your arms and legs, edema in the lungs and abdomen is also possible. This is known as “non-pitting” edema because if you pressed on the swollen area with your finger, it wouldn’t leave a pit, or indentation. Some causes of edema that develop in places other than the arms and legs include:
- Lymphedema: Lymphedema means there is damage to the lymphatic system and the body can’t drain fluids properly. This may cause a non-pitting edema in the arms or legs. A disturbance to the lymphatic system may occur after procedures like lymph node surgery, a mastectomy and radiation therapy. Obesity or venous insufficiency may also cause it. (10)
- Liver diseases: Liver disease can cause ascites. This means edema in the abdomen. Ascites happens because conditions of the liver, like cirrhosis, cause protein levels to become too low and create congestion in the liver. This causes pressure in the blood vessels and allows fluids to seep out into the abdomen.
Treatment for peripheral edema depends on the cause of the condition. Doctors will attempt to pinpoint the cause of the swelling by completing a thorough history and examination. He or she will also test your urine in order to make a diagnosis. The treatment plan will depend on the underlying disorder or issue that’s causing fluid retention. Usually a doctor will recommend restricting sodium intake in order to minimize fluid retention and he will prescribe diuretic therapy. (11)
Diuretics (like Lasix) are commonly prescribed to patients with heart failure in order to treat peripheral edema. Although emergency diuretics are sometimes necessary, patients who use diuretics for a long period of time sometimes become dependent on them and experience withdrawal symptoms when they stop taking these medications. Research shows that chronic diuretic use can lead to potassium deficiency and the depletion of blood volume in your blood vessels. (12)
For patients with non-pitting edema, diuretics are usually not effective. Because non-pitting edema is difficult to treat, doctors will commonly suggest elevating the legs periodically and wearing compressive stockings or devices to reduce swelling.
7 Natural Treatments for Peripheral Edema
1. Reduce SodiumConsumption
Your kidneys work to control the amount of salt that stays in your body by excreting salt through urine. This is also regulated by certain hormones and physical factors. But when the kidneys aren’t working properly, which can be the result of kidney disease or decreased blood flow due to heart problems, the body retains salt. Retaining salt leads to water retention and swelling because water follows sodium in the body. (13)
People who are prone to peripheral edemas should reduce their consumption of sodium foods, like table salt, soy sauce, olives, ham, salami and bacon. Many processed and packaged foods are also high in sodium. Stick to eating fresh produce, lean protein and healthy fats instead. It also helps to cook more foods at home so you can control the amount salt you use in your meals.
2. Move Around
To keep your bodily fluids pumping back to your heart, you need to stay active and move around throughout the day. If you work at a desk for several hours a day or you’re on a long flight, take frequent breaks. Stand up and walk around a bit. You want to keep the blood flowing in your legs so that fluid won’t pool and cause swelling. Aim to get up and move around 5–8 times per day, even if it’s just for 10 minutes.
The human body is designed to move. With so many of us spending up to 70 percent of our days sitting down, we can run into some serious health issues. A sedentary lifestylecan lead to reduced blood circulation. This causes swollen legs, ankles and feet, blood clots and pain. Not sure how to stay active during the day? Try having a walking meeting at work instead of sitting in a conference room. Or choose to pick up your lunch during the day instead of opting for delivery. Standing workstations are also gaining popularity and they can certainly help to reduce lower extremity edema. You can also set an evening routine that involves a short walk after dinner and then some stretching before bed. It really doesn’t matter how you move your body. Just avoid too much sitting so that your blood can continue to flow properly.
3. Eat (or Drink) Parsley
Parsley can be used as a natural diuretic that helps to relieve water retention and bloating. It does this by stimulating the production of urine by the kidneys and it draws out excess water that can cause peripheral edema. (14)
One of the best ways to use parsley as a natural and safe diuretic is to make parsley tea. You can do this by adding a quarter cup of chopped parsley to one cup of boiling water. Let the tea steep for about 5 minutes. Strain the parsley leaves and add a teaspoon of honey. You can drink parsley tea twice a day or when you notice symptoms of water retention. Keep in mind that women who are pregnant should not consume parsley tea because it’s a very powerful herb that may cause complications. To treat mild edema, add parsley to soups, salads or even juices.
4. Drink Dandelion Tea
Dandelion root serves as a natural diuretic. It allows your liver to eliminate toxins that can be causing inflammation. A 2009 study published in the Journal of Alternative and Complementary Medicine found that when fresh leaf dandelion extract was ingested by volunteers, it caused a significant increase in the frequency of urination in the five-hour period after the first and second dose. Researchers concluded that dandelion shows promise as an effective and natural diuretic for humans. (15)
To use dandelion as a diuretic to treat less severe cases of peripheral edema, you can buy dandelion tea at your local health food store. Or you can make your own. To make dandelion tea, simply steep the root or flowers for 30 minutes in boiling water. Then strain the dandelion and it’s ready to drink. Start by drinking a small amount to make sure that you don’t experience any adverse reactions.
5. Use Essential Oils
Grapefruit and fennel essential oils help to reduce water retention because they work as natural diuretics and they reduce inflammation. You can use both oils to stimulate blood circulation and relieve swelling associated with peripheral edema.
Grapefruit essential oil works by activating the lymphatic system and helping to control fluid retention. It promotes the detoxification of toxins and waste that can lead to inflammation and bloating. It also increases blood flow, thereby reducing fluid retention in the legs and relieving joint pain and aches that develop when you’ve been standing or sitting in the same position for too long. To use grapefruit oil to relieve the symptoms of peripheral edema, simply combine 3–4 drops of grapefruit with 1 teaspoon of coconut oil. Massage the mixture into the affected area. You can do this 2–3 times daily until the swelling has gone down. (16)
Fennel oil also helps to relieve inflammation and remove wastes that can cause swelling. It also has diuretic properties and can be used internally or topically to relieve peripheral edema symptoms. Just add 1–2 drops of fennel essential oil to warm water or a cup of herbal tea (like chamomile). Or combine 3–4 drops of fennel with 1 teaspoon of any carrier oil and massage the mixture into the affected area. (17)
6. Get a Massage
A gentle massage that promotes the flow of blood to your heart can help to remove pressure on your blood vessels that may be causing swelling. Massage therapy is recommended for less severe edema caused by water retention. A study published in the International Journal of Nursing Practice evaluated the effect of foot massages for decreasing lower leg edema in late pregnancy. Eighty pregnant women participated in the study. Half of them received a 20 minutes foot massage every day for five days. Compared to the control group, who received no massage, the experimental group had a significantly smaller leg circumference after the five days of massage. (18)
7. Elevate the Affected Area
To reduce water retention in your legs, try to elevate the affected area a few times a day in order to relieve pressure. This can be helpful after a day of work, when you’ve been sitting or standing in the same position for an extended period of time. This can also be extremely helpful for pregnant women who are experiencing swollen legs, ankles and feet. Simply prop one or two pillows under your feet for 15–30 minutes at a time. (19)
Sometimes, lower extremity edema can be a sign of a blood clot in your lungs or a serious heart condition. If you experience peripheral edema along with symptoms like chest pain, shortness of breath or dizziness, seek medical care immediately. If your peripheral edema occurs suddenly, seemingly out of nowhere, or it’s a result of trauma to your arm or leg, you should also see your health care provider for treatment.
Speak to your health care provider before using any herbal remedies if you are pregnant and want to relieve a peripheral edema naturally. And only receive a massage from a licensed prenatal massage therapist.
Final Thoughts on Peripheral Edema
- Peripheral edema means swelling in your arms and legs. This happens when fluid gathers in your tissues and causes a heavy, swollen and even painful area in the body.
- The symptoms of peripheral edema depend on the cause of the condition. You will generally notice a swollen area that stretches the skin and can feel warm to the touch.
