Let me preface by saying I do not have experience on this treatment with those who are mobility restricted, but it has worked well on the mobile! I know of no reason why it would not help for the infirm also. I have even tried it myself due to severe constipation caused by medications. My preference is Cascara Sagrada, an herbal supplement. From personal experience, I was having to use 400mg Colace BID and Dulcolax on a weekly or bi-weekly basis to achieve any sort of regularity. Movement of the bowel was still painful and difficult with this regemin. A friend guided me to Cascara Sagrada, and I am amazed at its effectiveness. Rather than overstimulating the bowel to a painful evacuation, it seems to awaken and coordinate the natural bowel contractions. Voila! A working bowel! It is taken as one 450mg dose daily. Through research I have done, I have not been able to find information on a dosing schedule for continuous usage. A dose of Cascara Sagrada every other day along with 200mg Colace BID seems to be effective without any unwanted side effects. As stated in other posts, adequate fluid intake is also necessary. Hope this works for you and others!
