My husband, is having severe stomach issues for about 8 months or so. He has had an upper and lower GI. Found he has gastritis and a hiatal hernia, where the food pipe joins the stomach. He has had a full body scan also. He is on medical marijuana and antidepressants, plus hydro-codeine. He is having bowel issues, constipation, then when urges come immediately an emergency (now) and resulting in accidents. He is now having very bad dry heaves, along with the terrible stomach issues. Drs. not finding what is going on. Any suggestions.
