Obesity Increases Risk of Lymphedema and Varicose Veins
As people age or become obese, the lymphatic system experiences a series of functional declines: the elasticity of lymphatic vessels decreases, lymph nodes weaken, and toxins can accumulate, leading to blockages in lymphatic vessels or excessive fat compressing the vessels, hindering the normal flow of lymph and disrupting their function. As lymph accumulates, surrounding tissues gradually swell, resulting in lymphedema.At the same time, aging or obesity can also cause a decrease in the elasticity of the venous walls and a decline in valve function, leading to poor blood return and blood pooling in the veins. As the pressure within the veins increases, surrounding tissues will gradually swell, ultimately forming varicose veins.
In a healthy lymphatic system, fluid flows smoothly without obstruction. However, as we age or experience obesity, the lymphatic system may slow down and become blocked. When lymph vessels or lymph nodes cannot function properly, fluid flow is impeded, leading to the accumulation of lymph and toxins. Like a clogged sink, when fluid has no place to drain, it builds up, causing overflow and backflow. This accumulation increases pressure in the legs, resulting in heaviness, swelling, and pain, making each step increasingly difficult. Over time, the condition often worsens rather than improves.
