What activity should a patient at risk of developing lymphedema avoid?

A patient at risk of developing lymphedema should avoid exercising in a hot environment because heat can cause blood vessels to dilate, which may lead to increased fluid accumulation in the affected area. Lymphedema results from an impaired lymphatic system, and any situation that encourages swelling or fluid retention should be approached with caution.

Exercising in a hot environment can exacerbate symptoms by increasing fluid volume in the interstitial spaces, thereby potentially worsening the condition. It's essential for patients at risk of lymphedema to manage their body temperature and avoid activities that could trigger an inflammatory response or fluid pooling.

On the other hand, exercising with light resistance, in a cool environment, or while wearing compression garments can be beneficial for patients at risk of lymphedema. Light resistance exercise helps to build strength without overtaxing the body. A cool environment is generally more favorable as it helps to minimize perspiration and heat accumulation, which can, in turn, lower the risk of swelling. Wearing compression garments during exercise helps maintain lymphatic flow and reduces the chance of swelling by providing external pressure to the affected areas.
