Weight changes in hot weather: a critical sign for heart patients

Sudden changes in body weight during hot weather serve as a critical clinical indicator for patients with heart disease. German cardiologists report a direct link between daily weight fluctuations and the risk of cardiovascular decompensation-a state where the heart can no longer pump enough blood to meet the body's needs. Weight Fluctuations in Heat High temperatures trigger active cooling through sweating, which leads to the loss of fluids and electrolytes. This process increases blood viscosity, forcing the heart to work harder. While healthy individuals generally tolerate this stress, it poses a significant risk for patients with myocardial pathology. Weight changes in heat typically signal two opposite conditions:
