Treating the temporary symptoms not related to disease or illness can be easily managed with over the counter remedies or natural diuretics . One of the most common is dandelion, which can be eaten or made into a delicious tea. Celery , watermelon and parsley are also considered natural diuretics as well, and can be enjoyed in small amounts to help reduce the water hoarding the body is engaging in. And, while natural diuretics for water retention are helpful to add into a diet, avoiding salt is even more important. Avoiding excess sodium not only contributes to lower blood pressure, but it is very important to a water retention diet because of the delicate water to sodium balance the body needs to consistently maintain.
If, on the other hand, the capillaries are very leaky, and tissues are therefore retaining both water and protein , then diuretics can do more harm than good.  They will cause the kidneys to remove fluid more rapidly from the blood while at the same time the protein in the tissue spaces will be drawing fluid from the blood into the tissues . The result can be dehydration of the blood . Over time, the use of diuretics can aggravate water retention of this type, as the body will learn to hold on to water in an attempt to avoid becoming dehydrated . 
Water retention is a common problem that most people face at some point in their lives. A combination of diet, lifestyle changes, supplements, and diuretics can work together to relieve edema and stop it from returning. The biggest thing to remember is that edema is caused by a combination of too much sodium in the body and poor circulation. By reducing salt intake and encouraging the excess water to leave with diuretics, edema will quickly fade. Combining these lifestyle changes with an increased exercise regimen will also make a difference in reducing edema .
