The cells in the human body contain millions of tiny pumps that regulate the movement of fluids in and out. The sodium-potassium pump is a protein that uses the cell’s energy to expel sodium ions (Na+) and bring in potassium ions (K+). This process is essential for maintaining fluid balance in and around cells. If this pump malfunctions, water accumulates outside the cells, leading to water retention, particularly in the legs and ankles.
Poor regulation of cellular fluids can be caused by high blood sugar. Indeed, excessive sugar accumulation in the blood is directly linked to a process called glycation. This process occurs when sugar binds to a protein, such as hemoglobin, preventing it from functioning properly. Glycated proteins block blood flow, causing fluid to leak from blood vessels and contributing to swelling of the legs and feet.
