When possible, treatment involves resolving the underlying cause. Many cases of [[heart]] or [[kidney]] disease are treated with [[diuretics]].<ref name=":0" />

Treatment may also involve positioning the affected body parts to improve drainage. For example, swelling in feet or ankles may be reduced by having the person lie down in bed or sit with the feet propped up on cushions. [[Intermittent pneumatic compression]] can be used to pressurize tissue in a limb, forcing fluids—both blood and [[lymph]]—to flow out of the compressed area.<ref>{{cite journal |last1=Zaleska |first1=Marzanna |last2=Olszewski |first2=Waldemar L. |last3=Cakala |first3=Marta |last4=Cwikla |first4=Jaroslaw |last5=Budlewski |first5=Tadeusz |title=Intermittent Pneumatic Compression Enhances Formation of Edema Tissue Fluid Channels in Lymphedema of Lower Limbs |journal=Lymphatic Research and Biology |date=June 2015 |volume=13 |issue=2 |pages=146–153 |doi=10.1089/lrb.2014.0010 |pmid=25748341 |pmc=4492553 }}</ref>
