If it is bacterial infection such as H.pylori, DGL (deglycerinized licorice) will kill the bacteria and heal your gut. You can find this at any health food store and it doesn't cost much ($10-15).
Hi there!
The smell of rotten eggs comes from sulphur containing foods, dairy products,eggs,red meat,milk,cabbage,broccoli,mustards ,onion, sweet potatoes, vitamin B1,biotin,legumes,peas,beans ,walnuts, almonds are all sulphur containing foods. The common causes of such smell are a gastro-intestinal infection caused by the Helicobacter pylori bacteria or Giardia.Parasitic infestations like giardia lamblia, fructose intolerance can also cause sulphur burps. Other causes are celiac disease, Crohn’s disease etc. Diets high in protein, prescription medications and sub acute intestinal obstruction all can cause these symptoms. Your child should be given plenty of water to avoid dehydartion.Avoid processed and fast foods. If the cause of the burps is a bacterial infection, a course of antibiotic treatment may be needed. See a doctor. Keep me posted.
Best luck and regards!
