The terms proximal (from Latin proximus, meaning 'nearest') and distal (from Latin distare, meaning 'to stand away from') are used to describe parts of a feature that are close to or distant from the main mass of the body, respectively.
But, with Citrucel and/or Metamucil you can start with one teaspoon mixed in water or juice. If you have diarrhea don't use the preparation with artificial sweeteners. Use the one with sugar. I think artificial sweeteners (some of them) might cause more diarrhea.
1 Review. Metamucil is a bulk-forming fiber that is used to treat constipation and may also reduce cholesterol when taken every day. The generic name for this fiber is psyllium. The fiber absorbs liquid in the intestines and swells and forms a bulky stool, which is easy to pass. The active ingredients are the seed husks of the psyllium plant. The Metamucil brand has been in existence since 1934.
