What Causes Stinky Burps: Home Remedies For Foul Smelling Burps

We all burp (belch) sometime or the other, but most of the time it is odorless. Many people consider burping as a social stigma, but at times it is unavoidable. However, burps are not always odorless, they may be stinky and smelly, and in such situation it can be a cause of embarrassment.

Actually, burping is a natural process of expelling accumulated stomach gas. Usually it results when large amount of gas is swallowed at a time. It can also arise from the gas produced in digestive tract. This gas travels upwards to the esophagus and expelled out through the mouth.

Many times belching produces typical smell of rotten egg or that of sulfur. It can be associated symptom of a disease condition or simply occur as a result of indigestion. So let us know the reasons why it occurs and what you can do to cure burps.

What Causes Foul Smelling Burps?

  • The most important reason for burps that produce foul odor is probably due to undigested food in stomach. When this food starts to ferment, it can cause foul smelly burps.
  • Stinky smell of rotten eggs or that of sulfur, which comes after a burp, is due to a gas formed in digestive tract. It is called hydrogen sulfide gas. The gas is produced when you eat sulfur containing food. When the food is metabolized in the stomach and intestine, hydrogen sulfide is produced. The whole chain of breaking food protein is done by bacteria residing in the digestive tract. They can be harmful bacteria or normal intestine bacteria.
  • Sulfur containing foods are: asparagus, garlic, onions, parsley, sweet potatoes, Swiss chard, beans, peas, soy products, corn, sunflower seeds, oats, red meat, eggs, poultry etc. ¬†Avoid them when you have bad burps.
  • Excess of bile which has a sulfuric taste when present in digestive tract can lead to foul odor belching.
    This happens when you eat large meal at a time. In order to digest large meal, liver releases large amount of bile in the intestine. And this may lead to foul stinky smell when you belch.
