I'm currently traveling through South America. In September I got hit with two concurrent infections: giardia and then salmonella. They were treated with Nitazoxanide and Cipro respectively and I felt fine after then.
But after a week, a couple symptoms have stayed: massive amounts of gas, rumbling stomach noise, and sometimes small and loose but regular stools. No diarrhea. The stomach noise and gas seem to go hand in hand. I found that red meat, caffeine, carbonated beverages, tomatoes, and thick dairy seems to make it worse. I go a couple days with almost zero symptoms, then a week with symptoms. I haven't lost any weight and my appetite is normal.
One doctor gave me another round of cipro and that did nothing. Back on nitazoxanide and that did nothing as well. I'm still in south america so it's difficult to find a competent english-speaking doctor.
Ive been downing active yogurt daily and trying to eat simple foods. Comments/suggestions? The gas is the most annoying symptom. My stomach can be completely empty but large amounts of gas are coming from nowhere. Most of the time it doesn't smell.
