The effect of soluble fiber dietary supplement on constipation in 3 patients with dysphagia who suffered from cerebral infarction with special reference to serum diamine oxidase activity

Abstract

Dietary supplement with soluble fibers was given to 3 patients with stroke and dysphagia and obtained improved defecation condition. These clinical effects of soluble fibers should reduce the burden of the patients and families. Long-term inaction of the gastrointestinal tract or continuation of supplementary diet without fibers will induce atrophic intestinal mucosa and abnormal intestinal function. The addition of dietary soluble fibers into supplementary diet can improve the atrophy of the intestinal mucosa and the decline in function of the intestine, constipation and meteorism. The serum diamine oxidase activity, which is regarded as a parameter of intestinal mucosal atrophy, increased with the improvement of constipation and meteorism after addition of dietary soluble fibers. We think that dietary soluble fibers are necessary, especially for the patients who have low diamine oxidase activity. The measurement of serum diamine oxidase activity should be an effective method to evaluate intestinal mucosal atrophy and estimate dietary fibers. We selected a supplementary diet, Enrich-SF, which contains Fibaron, a kind of soluble fiber, galactomannan purified from guar, because this canned supplementary diet has only one kind of soluble fiber. Some consider that soluble fibers are fermented to short-chain fatty acids in the intestinal tract, and improve the disordered bacterial flora in the intestine, resulting in more regular intestinal function. Attention should be paid to dietary fibers in cases of long-term tube feeding.
