Indeed, if swelling persists even after cutting back on salty foods and drinking water, it is time to examine other signals from the body. Modern medicine identifies 'hypoproteinemia' as one cause of chronic edema. Problems arise particularly when blood proteins, especially 'albumin', are deficient. Albumin plays a crucial role in maintaining intravascular osmotic pressure, holding fluid inside blood vessels so it does not leak out. Put simply, it acts like a magnet that pulls and holds water within the blood vessels.
If protein intake drops due to dieting or eating habits, blood albumin levels decline. When that happens, intravascular osmotic pressure decreases, allowing fluid from the blood to seep into the interstitial spaces between cells outside the blood vessels. This accumulated fluid manifests as the edema we feel. It appears prominently in areas heavily influenced by gravity, such as the legs, ankles, and around the eyes, and in severe cases can lead to generalized edema where the entire body swells. Edema caused by protein deficiency feels different from simply gaining weight. It is characterized by pitting edema, where the skin stays indented and does not quickly rebound when pressed.
Such hypoproteinemia can have multiple causes beyond mere intake deficiency. Chronic malnutrition, extreme vegan diets, digestive system disorders impairing protein absorption such as Crohn's disease or celiac disease, kidney diseases that increase protein loss such as nephrotic syndrome, and liver diseases that impair albumin production in the liver such as liver cirrhosis can all serve as causes. Furthermore, severe inflammation, burns, and hemorrhage can increase protein consumption, inducing hypoproteinemia. Therefore, if swelling is accompanied by symptoms such as fatigue, muscle loss, dry skin, alopecia, and brittle nails, it may not be simple puffiness but a warning sign of protein deficiency sent by your body. It is essential to consult a specialist to identify the precise cause, improve dietary habits, and receive appropriate treatment. Remember that healthy water pathways in our body begin with sufficient protein.
