A deficiency in albumin, a type of protein, can cause swollen legs.
Understanding Albumin and Swelling (Edema)
Albumin plays a vital role in maintaining fluid balance within the blood vessels. It helps to prevent fluid from leaking out into surrounding tissues. When albumin levels are low, the blood loses its ability to retain fluid effectively.
-
How Albumin Works: Albumin acts like a sponge, drawing water back into the blood vessels.
-
Deficiency Leads to Leakage: When there is a lack of albumin, fluid leaks out of the blood vessels and accumulates in the surrounding tissues, leading to swelling, particularly in the legs and feet, due to gravity.
The Role of Albumin
Albumin's main job is to keep fluid inside blood vessels. When you don't have enough albumin, fluid can leak out. This causes swelling.
Conditions Associated with Low Albumin Levels
Several medical conditions can lead to low albumin levels (hypoalbuminemia), including:
- Kidney Disease: Damaged kidneys may leak albumin into the urine.
- Liver Disease: The liver produces albumin, so liver damage can reduce albumin production.
- Malnutrition: A diet lacking sufficient protein can result in low albumin levels.
Table: Albumin Deficiency and Its Effects
| Factor | Description | Effect on Legs |
|---|---|---|
| Albumin Function | Protein that retains fluid in blood vessels. | Prevents fluid leakage into surrounding tissues. |
| Albumin Deficiency | Lack of albumin in the blood. | Fluid leaks from blood vessels, accumulating in legs and feet. |
| Resulting Condition | Edema (swelling). | Swollen legs and feet. |
| Contributing Conditions | Kidney disease, liver disease, malnutrition, inflammation | Worsening of edema depending on severity of underlying condition. |
