The study of energy metabolism and phenotypical adaptation in patients with ulcer disease has revealed deficiency of energy metabolism and defective phenotypical adaptation in the form of its tension or failure of adaptive processes. Sanatorium treatment with oral intake of mineral water, mineral baths, fangotherapy, limontar-electrophoresis and millimetric waves promoted normalization of energy metabolism and adaptive processes. Impact of different physiotherapeutic factors on energy metabolism and adaptation of the organism is described.
