My daughter is 11 yrs old and suffers from cronic constipation for 5 years & also daytime wetting. she weighs only 25 kgs she's had all tests and they come back negetive its very frustrating she been in hospital 8 times last year to be cleaned out this time about 2 weeks ago it took 12 litres of golightly to clean her out. She is now on durolax 2 tablets to start with now on to 4 tablets & also banefibre 1 teaspoon a day. For the sensation to come back is to keep the bowel empty it takes time & alot of hard work. We have been everywhere to no avail. All I can say is, don't give up.
