I am traveling and have had mild diarrhea for a month. Generally have less appetite and have lost 10+ pounds. Began around the time I ate clearly bad?

Travelers diarrhea. Likely travelers diarrhea related to change in flora/fauna with travel. Lomotil (diphenoxylat and atropine) can provide temporary relief. . If you have persistent symptoms you need a stool culture for pathogens including giardia and appropriate antibiotics.
