Dietary treatment of lymphedema by restriction of long-chain triglycerides

Two patients suffering from idiopathic unilateral lower limb lymphedema were treated with a diet in which long-chain triglycerides (LCT) were drastically restricted. From the beginning of the treatment, a distinct improvement was observed in both patients, with reduction of the affected limb perimeters, decrease of edema tension, and decrease of skin turgescence. Patient A underwent weight loss, and the reduction of the diameter of the affected limb was greater than that in the nonaffected limb. In patient B, whose weight remained stable during the study, the diameter of the affected limb underwent a remarkable diminution, while no changes were detected in the nonaffected limb. To the authors' knowledge, this is the first report of dietary treatment of idiopathic lymphedema, these being preliminary results of an ongoing study in a group of patients suffering from lymphedema treated with a low LCT diet.
