Why is strict bed rest recommended for patients with Rheumatic fever?

Strict bed rest is recommended for patients with rheumatic fever primarily to prevent complications related to the disease. Rheumatic fever can lead to serious manifestations, particularly affecting the heart, such as rheumatic heart disease, which involves damage to the heart valves. By adhering to strict bed rest, patients can minimize physical stress and reduce the heart's workload, thereby lowering the risk of exacerbating heart-related complications.

Additionally, bed rest helps in managing symptoms such as joint pain and inflammation, which are common in rheumatic fever. This approach allows the body to focus on recovery and decreases the likelihood of further injury to the heart or other affected organs. While hydration, managing fever, and maintaining appetite are important aspects of care, they do not capture the primary goal of bed rest in this context, which is specifically to mitigate the risk of complications that could result from physical activity during a phase of active inflammation.
