Edema, or the swelling of the legs and feet, occurs when fluid becomes trapped in the body’s tissues. This common issue is often triggered by simple factors such as gravity, high temperatures, excessive salt consumption, or remaining in a seated or standing position for too long.
Under normal circumstances, your calf muscles act as a pump to return fluid to the heart. However, when your mobility is restricted, fluid can pool in the lower extremities, resulting in a feeling of heaviness, tight skin, and general discomfort.
The Impact of Injury
Swelling can also be a localized response to trauma. When you experience a strain or a twist, your body naturally directs extra fluid to the affected area to facilitate the healing process.
When Swelling Indicates a Deeper Concern
In certain cases, persistent swelling may be a symptom of more significant internal health issues. Complications involving the heart, liver, or kidneys can disrupt the body’s ability to regulate fluid effectively, causing it to accumulate in the feet and legs.
