The first step in getting rid of excess bodily fluid is to reduce salt intake as sodium, found in salt, will make your body hold water. Sitting in a sauna or hot tub will also help as it will increase sweating and the elimination of excess water. A range of plant foods as well as concentrated supplements, such as asparagus, watermelon, parsley and hawthorn will likewise eliminate excess fluids. Some of these herbs can be fairly potent and you should consult with your physician if you have a medical condition.
Reduce salt intake. The first step in eliminating excess body fluid is to reduce your salt intake. Sodium, found in table salt, is one of the primary elements responsible for water retention in the body and its reduction will usually lead to the loss of excess fluids. Try to add less salt to your dishes and read nutritional labels for the sodium content of packaged foods. The recommended daily allowance (RDA) for sodium is 2,500 milligrams, but most of us consume far more. Reducing your salt intake to the RDA is also good for general health and longevity.
Sweat gently. Sweating will naturally eliminate water and any activity that will help you sweat without placing excess stress on your body will help to get rid of excess fluids. Athletes trying to lose water weight before competition (usually to qualify for a specific weight class) have devised interesting and often extreme methods to accelerate sweating. However, for the layperson a brief visit to the sauna or a short session in the hot tub is all that is required. If you are unaccustomed to these, start slowly and do not push yourself. Avoid extreme heat if you have an underlying health condition, including but not limited to: heart disease, hypertension and kidney disease.
Drink more water. Although it may sound counterintuitive, the more water you drink, the less fluid you will retain. Restricting water intake will only place your body into preservation mode, as it will think that a drought is approaching, and make it hold onto water. Consuming water, on the other hand will increase the rate of sweating and urination, both of which will help eliminate excessive sodium and reduce water retention.
Consider herbal diuretics. A diuretic is any substance that accelerates fluid excretion. In addition to prescription medications used for the treatment of hypertension, a range of plants and concentrated plant extracts in pill form help eliminate excess water. Natural diuretics include caffeine, asparagus, onion, watermelon, celery, parsley and hawthorn. Depending on quantity and dosage, some of these diuretics can be potent, so consult a health-care professional or herbalist before using these plant-based diuretics.
