Why does this apply to legs?
According to research published in the National Library of Medicine, blood naturally flows slower through the deep veins of the legs than in many other parts of the body. This is because gravity works against upward blood flow, and the legs are located far from the heart. As a result, this area is particularly susceptible to blood clots.

With abnormal clotting signals circulating throughout the body, the legs are one of the most common places for a clot to occur. The forming clot disrupts normal blood flow and quickly leads to swelling and inflammation in the affected area. Some people may also experience pain, warmth, or redness, but for many patients, the only visible warning sign is leg swelling.
Protein deficiency and systemic edema
Not all swelling associated with pancreatic disease is caused by blood clots. In some cases, swelling can occur in both legs due to a condition called systemic edema, which occurs when the body's fluid balance is disturbed.
Albumin, a protein produced by the liver, plays a key role in maintaining fluid in blood vessels. When albumin levels drop too low, fluid begins to leak out of the vessels and accumulate in surrounding tissues, causing swelling.
A pancreatic tumor can disrupt this process because it can block the release of important digestive enzymes. Without these enzymes, the body has difficulty properly absorbing proteins from food. Over time, this can lead to a condition known as hypoalbuminemia, especially in the more advanced stages of pancreatic disease.
