Digestive system going bonkers?

Hi all. I've recently started experiencing a wide variety of digestive system dysfunctions. From low-acidity heartburn, to upset stomach, bloating, diaharrea (mostly clear water), to gas (burpy egg gas, and gas on the other end too).

The symptoms are fairly uncomfortable when combined but none of them have a very high level of severity and it seems like something I can simply endure until my body fights off whatever is disturbing its balance while taking some antacids to relieve some of the heartburn/bloating. That said are there any warning signs here of a disorder that has a good probability of worsening?

Do my symptoms match the profiles for anything contagious?
