👉 A failing fluid, often referred to as a failing circulatory system or cardiovascular failure, occurs when the body's circulatory system, responsible for transporting oxygen, nutrients, and waste products, becomes impaired. This can lead to inadequate blood flow to vital organs and tissues, causing symptoms such as shortness of breath, fatigue, swelling in the legs and ankles, and rapid or irregular heartbeat. The failure can stem from various causes, including heart disease, high blood pressure, diabetes, or kidney problems, and it can progress to severe complications if left untreated.
