What Causes Swelling During Pregnancy and When Is It Serious?

Factors That Can Increase Swelling

Several factors can make pregnancy-related swelling more noticeable.

Hot Weather

Higher temperatures encourage blood vessels to expand, allowing more fluid to leak into surrounding tissues. Many women notice greater swelling during summer months.

Standing for Long Periods

Jobs or activities that require prolonged standing can reduce circulation and increase fluid buildup in the legs and feet.

Sitting Without Movement

Remaining seated for long periods can also affect blood flow. Taking regular breaks to stretch and walk around helps encourage healthy circulation.

Multiple Pregnancy

Women carrying twins or more often experience greater swelling because their bodies produce more blood and retain more fluid.

High Salt Intake

While completely avoiding salt is not recommended during pregnancy, consuming excessive amounts of highly processed foods may contribute to increased fluid retention.
