The aim of the present study was to examine the influence of acupuncture on
chronic constipation in children and to investigate their basal plasma pan
opioid level and the changes of this treatment. Seventeen children constipa
ted for at least six months were treated by five weekly placebo acupuncture
sessions, followed by 10 weekly true acupuncture sessions. Their parents f
illed a bowel habit questionnaire. Panopioid activity was measured at time
0 and after 5, 10, and 15 acupuncture sessions. The frequency of bowel move
ments in males increased more gradually compared to females and reached a m
aximal improvement only after 10 true acupuncture sessions, from 1.4 +/- 0.
6/week to 4.4 +/- 0.6/week and females from 1.4 +/- 0.3/week up to 5.6 +/-
1.2/week. The basal panopioid activity was lower in constipated children as
compared to the control population and increased gradually up to control l
evel after 10 true acupuncture sessions. This study is the first to describ
e a successful treatment by acupuncture of constipated children.
