EdemaAlso listed as: Water retention
Edema (also known as dropsy or fluid retention) is swelling caused by the accumulation of abnormally large amounts of fluid in the spaces between the body's cells or in the circulatory system. It is most common in feet, ankles, and legs. It can also affect the face and hands. Pregnant women and older adults often get edema, but it can happen to anyone. Edema is a symptom, not a disease or disorder. Widespread, long-term edema can indicate a serious underlying health problem.
Signs and Symptoms
These will vary and may include the following:
- Swollen limbs (possibly accompanied by pain, redness, heat)
- Facial puffiness
- Abdominal bloating
- Shortness of breath, extreme difficulty breathing, coughing up blood
- Sudden change in mental state or coma
- Muscle aches and pains
What Causes It?
Some of the following factors may cause edema:
- Sitting or standing for long periods
- Certain medications
- Hormonal changes during menstruation and pregnancy
- Infection or injury to a blood vessel, blood clots, or varicose veins
- Blocked lymph channels (lymphedema)
- Allergies to food or insect bites
- Kidney, heart, liver, or thyroid disease
- High or low blood pressure
- Eating salty foods
- Brain tumor or head injury
- Exposure to high altitudes or heat, especially when combined with heavy physical exertion
What to Expect at Your Provider's Office
Your health care provider will look for varicose veins, blood clots, wounds, or infections. An x-ray, CT scan, MRI, urine test, or blood test may be necessary. Pulmonary edema, which occurs when fluid builds up in the lungs, can be caused by other diseases such as cardiovascular disease or by climbing at high altitudes. It can be life threatening and may require hospitalization.
Treatment may involve using compression bandages and pressure sleeves tightened over swollen limbs to help force the body to reabsorb the fluid. Other options include a salt reduction diet, daily exercise, resting with legs elevated above the heart level, wearing support hose, taking a diuretic, and massage.
- Medication for your underlying disorder -- talk to your health care provider.
- Diuretics -- for example, loop diuretics or potassium sparing diuretics. These medicines reduce body fluid levels, but they also deplete important vitamins and minerals, which can result in loss of bone mass. Diuretics may have several other possibly serious side effects.
Surgery may be needed to remove fat and fluid deposits associated with a type of edema called lipedema, or to repair damaged veins or lymphatic glands to reestablish lymph and blood flow.
Complementary and Alternative Therapies
The following nutritional and herbal support guidelines may help relieve edema, but the underlying cause must be addressed. Tell your health care provider about any complementary or alternative therapies you are considering.
Nutrition and Supplements
Following these nutritional tips may help reduce symptoms:
- Eliminate suspected food allergens, such as dairy (milk, cheese, and ice cream), wheat (gluten), soy, corn, preservatives, and chemical food additives. Your health care provider may want to test you for food allergies.
- Reduce salt intake. If you are taking diuretics, your doctor should give you specific instructions about salt intake.
- Eat foods high in B-vitamins and iron, such as whole grains (if no allergy), dark leafy greens (such as spinach and kale), and sea vegetables. If you are taking certain diuretics, your health care provider may give you specific instructions about getting different nutrients into your diet, such as potassium. Potassium is in many vegetables. Follow your health care provider's instructions strictly.
- Eat natural diuretic vegetables, including asparagus, parsley, beets, grapes, green beans, leafy greens, pineapple, pumpkin, onion, leeks, and garlic. Some of these foods may interact with diuretic medications.
- Eat antioxidant foods, such as blueberries, cherries, tomatoes, squash, and bell peppers.
- Avoid refined foods, such as white breads, pastas, and sugar.
- Eat fewer red meats and more lean meats, cold water fish, tofu (soy, if no allergy), or beans for protein.
- Use healthy cooking oils, such as olive oil.
- Reduce or eliminate trans fatty acids, found in commercially baked goods such as cookies, crackers, cakes, French fries, onion rings, donuts, processed foods, and margarine.
- Avoid alcohol, and tobacco.
- Exercise lightly 5 days a week if your health care provider says you can.
You may address nutritional deficiencies with the following supplements:
- A multivitamin daily, containing the antioxidant vitamins A, C, E, the B-complex vitamins, and trace minerals, such as magnesium, calcium, zinc, and selenium. Many multivitamins contain calcium and potassium, two minerals your doctor may want you to avoid in large quantitites if you are taking certain types of medications. Talk to your health care provider.
- Vitamin C, 500 - 1,000 mg daily, as an antioxidant.
- Alpha-lipoic acid, 25 - 50 mg twice daily, for antioxidant support. Alpha-lipoic acid can interfere with certain cancer and diabetes medicines.
- If you use diuretics, your doctor may have you supplement with potassium aspartate (20 mg per day), since diuretics flush out potassium from the body and cause a deficiency. Do not take extra potassium without informing your doctor. Some diuretics do the opposite and cause potassium to accumulate in the body.
Herbs are generally a safe way to strengthen and tone the body's systems although they can interact with many medications and have certain side effects. As with any therapy, you should work with your doctor to determine the best and safest herbal therapies for your case before starting any treatment, and always tell your health care provider about any herbs you may be taking. If you are pregnant or nursing, do not use herbs except under the supervision of a health care provider knowledgeable in herbal therapies. You may use herbs as dried extracts (capsules, powders, teas), glycerites (glycerine extracts), or tinctures (alcohol extracts). Unless otherwise indicated, make teas with 1 tsp. herb per cup of hot water. Steep covered 5 - 10 minutes for leaf or flowers, and 10 - 20 minutes for roots. Drink 2 - 4 cups per day. You may use tinctures alone or in combination as noted.
- Bilberry (Vaccinium myrtillus) standardized extract, 80 - 100 mg 3 times per day for antioxidant support. Do not use bilberry if you are on blood thinning medications.
- Dandelion (Taraxacum officinale ), 4 - 10 g of dried leaf steeped in one cup hot water. Strain and cool. However, dandelion leaf is itself a diuretic so it should not be used while taking diuretic medications. Speak with your doctor. Do not use andelion if you have gall bladder disease, take blood thinning medications, or have allergies to many plants. Dandelion can interact with many medications, including antibiotics and lithium. Talk to your health care provider.
- Grape seed extract (Vitis vinifera), standardized extract, 360 mg 2 times daily, for antioxidant support. Evidence suggests that using grape seed extract may improve chronic venous insufficiency, which causes swelling when blood pools in the legs. Grape seed can interact with some medicines, including blood-thinning medications such as coumadin (Warfarin).
- Dry skin brushing. Before bathing, briskly brush the entire skin surface with a rough washcloth, loofa, or soft brush. Begin at your feet and work up. Always stroke in the direction of your heart.
- Cold made with yarrow tea.
- Contrast hydrotherapy involves alternating hot and cold applications. Alternate 3 minutes hot with 1 minute cold. Repeat 3 times to complete one set. Do 2 - 3 sets per day. Check with your health care provdier to make sure your heart is strong enough for this therapy.
- Put a pillow under your legs when you're lying down.
- Wear support stockings, which you can buy at most drugstores.
Acupuncture may improve fluid balance.
Therapeutic massage can help lymph nodes drain.
Excessive fluid retention during pregnancy (toxemia) is potentially dangerous to both you and your baby.
