Right arm swelling can be more common in older adults due to changes in circulation, chronic health conditions, and previous medical treatments.
As people age, several factors can make swelling in the right arm more likely:
Circulation changes: Blood vessels and lymphatic systems may not work as efficiently, leading to fluid buildup. Chronic conditions: Older adults are more likely to have heart, kidney, or liver diseases that cause swelling. Past surgeries or treatments: Removal of lymph nodes or radiation therapy, especially for cancer, can cause lymphedema (fluid buildup). Medications: Some drugs taken more often by older adults can cause fluid retention and swelling. Reduced mobility: Less physical activity can slow circulation, increasing swelling risk.
If swelling occurs suddenly, is painful, or doesn’t improve, it’s important to see a healthcare provider for evaluation.
