Can shingles affect the gastro intestinal tract? Since a bout of shingles in Dec. 2017, I have experienced lack of hunger, queasy stomach and sometimes stomach pain when ingesting food. When food has been taken, bowels become erratic and sometimes with spontaneous movements. Movements sometimes occur two or three times a day tho little food is eaten. Sometimes bowels appear to contain micous. Movements occur with little or no normal indicators such as stomach growling or gas passing. Occurences sometimes by just standin from a sitting position with no prior need to excrete felt before standing.
