Medications and Lifestyle Factors
Several medications may cause swelling as a side effect, including certain blood pressure medications, anti-inflammatory drugs, and hormone therapies.
A sedentary lifestyle can also play a role. Regular movement helps muscles push blood and lymphatic fluid back toward the heart. Long periods of sitting, particularly during travel or desk work, can increase the likelihood of swollen feet and ankles.
Lack of physical activity may worsen existing circulation issues and contribute to ongoing fluid retention.
When Swelling Could Be Serious
In some cases, swollen legs can be linked to more serious medical conditions.
