I have been suffering from gassy stool from the past 12 days. Initially it was green, pasty stool with gas but after being prescribed Metrogyl 400 for 5 days, the stool looks normal but is very gassy. It starts of normally but on entering the water it disintegrates. I am facing increased burping and gas from the start of this. Even drinking water makes me burp. From the past 2 days, i have been having sweet taste in my mouth(though blood
sugar is normal) along with weird sensations in my teeth during the evening. What should i do? Does this have some underlying cause ?
