Name a common complication of long-term immobility.

Deep vein thrombosis (DVT) is a common complication of long-term immobility due to the reduction in blood flow caused by the lack of movement. When a person remains immobile for extended periods, blood can pool in the veins, particularly in the lower extremities. This pooling increases the risk of clots forming in the deep veins of the legs. DVT can be particularly dangerous, as these clots can dislodge and travel to the lungs, causing a pulmonary embolism, which can lead to serious complications or even be life-threatening.

While conditions like constipation, pneumonia, and muscle atrophy are indeed associated with immobility, they do not pose the same immediate and critical risk as DVT. Constipation can arise due to decreased movement leading to slower gastrointestinal transit, pneumonia may be linked to reduced lung expansion and secretions pooling, and muscle atrophy is a gradual loss of muscle mass due to disuse. However, the acute nature and potential severity of DVT make it a critical concern for individuals who are immobile for extended periods.
