Objective To analyze the relations between the TCM syndromes and the nutritional status in the peritoneal dialysis patients with gastrointestinal symptoms in order to facilitate the clinical treatment.Methods The 81 peritoneal dialysis patients with gastrointestinal symptoms were differentiated according to the TCM differentiation treatment. They were scored based on their gastrointestinal symptoms. Their daily energy intake （DEI） and protein intake （DPI） per kilogram of body weight

and the serum albumin （ALB） level were measured.Results In the Ben-root-deficiency syndromes

there were 39 cases（48.1%） of spleen and kidney qi deficiency

16 cases （19.8%） of both qi and yin deficiency

10 cases （12.3%） of spleen and kidney yang deficiency

9 cases （11.1%） of both yin and yang deficiency

and 7 cases （8.6%） of liver and kidney yin deficiency. The DEI of those cases with spleen and kidney yang deficiency was significantly lower than that of those with spleen and kidney qi deficiency and both qi and yin deficiency （P<0.05 or P<0.01）. The ALB of those cases with spleen and kidney yang deficiency and both yin and yang deficiency was significantly lower than that of those who with spleen and kidney qi deficiency （P<0.01）. In the Biao-symptom-excess syndromes

there were 36 cases （35.3%） of blood stasis

26 cases （25.5%） of damp heat

25 cases （24.5%） of damp turbidity

12 cases （11.8%） of evil heat toxins

and 3 cases （2.9%） without Biao-symptom. The score of those cases with the syndrome of damp turbidity and damp heat was significantly higher than those who with the syndrome of evil heat toxins in comparison （P<0.01）.Conclusion Of the peritoneal dialysis patients with gastrointestinal symptoms

the syndrome of spleen and kidney qi deficiency is the main one in the deficiency syndromes

while the syndromes of blood stasis

damp heat

and damp turbidity are the main excess ones

and there is a certain relation with DEI and ALB in the nutritional indices.
