If You Notice These Signs, Take a Closer Look at What They Could Mean

Liver disease is another condition that can cause fluid retention. Advanced liver disorders may reduce the production of proteins that help keep fluid inside blood vessels, allowing fluid to collect in the legs and abdomen. Liver-related swelling is often accompanied by other symptoms such as jaundice, fatigue, or abdominal enlargement.

Not every swollen leg signals a serious illness. Spending long hours sitting during travel, standing throughout the workday, pregnancy, certain medications, hot weather, or minor injuries may all cause temporary swelling that improves with rest. However, swelling that persists for several days, becomes progressively worse, or occurs with pain, redness, fever, chest pain, or shortness of breath should never be ignored.

Doctors typically diagnose the underlying cause by reviewing medical history, performing a physical examination, and ordering appropriate tests such as blood work, urine analysis, ultrasound imaging, or heart evaluations when necessary. Because treatment depends entirely on the cause, self-diagnosis based on internet photos is never recommended.
