👉 Sustained fluid, also known as persistent or chronic fluid retention, refers to a condition where the body continuously retains more fluid than it normally would, leading to an accumulation of excess fluid in various tissues and organs. This can manifest as swelling (edema) in the legs, ankles, or abdomen, and is often accompanied by symptoms like shortness of breath, fatigue, and increased thirst. The underlying causes can range from kidney dysfunction, heart failure, liver disease, or hormonal imbalances to dietary factors and lifestyle choices. When the kidneys are unable to excrete enough fluid, or when there is an imbalance in the body's fluid regulation mechanisms, the excess fluid accumulates, disrupting normal bodily functions and leading to the symptoms associated with this condition.
