After Eating Something Specialy Heavy Meals I Keep On Burping

After eating something specialy heavy meals I keep on burping a lot, I feel relieved when I burp but after a minute I feel like I want to burp again. Together with this is a bloated stomach and excessive saliva on my mouth. I'm a litte bit confused as of what disease I am having right now, if it's hyperacidity or an acid reflux?
