My 80 yr old father is having a terrible time with constipation. Outside of Parkinsons he's quite fit but the lack of regularity is really getting him down. It has been particularly a problem since a barium enenma 2 wks ago. Is it related usually to medication or Parkinsons? Any ideas on how to deal with this? I would really appreciate any responses by e-mail. Thank you! -- Helen [log in to unmask]
