I Have Health Insurance! I Am Having Gastrointestional Issue. Been

I have health insurance! I am having gastrointestional issue. Been going on for nearly a week. Stomach and intestines making noises. Like they are at war. Passing a lot of puterid gas. So bad, it makes me gag. My stools are very loose. Lots of water leaving my rectum in bowel movments. The more water I drink the more my bowels want to evacuate. Lots of gurgling noises in my upper intestines. This problem started Saturday Jan 7. Today is Jan 12. spending a lot of time going to the commode. Anti Dihareha pills are not working. I also take Gas pills. They are not helping. I am a male 67 years old.
