Causes of sulfuric burp

Gas formation in the digestive system is normal. This gas is excreted through the rectum through belching or flatulence.

Digestive gas can occur when air is swallowed. When bacteria in the digestive tract break down food, they can also release gas as a by-product.

Sulfuric burps occur when the digestive tract releases a gas called hydrogen sulfide. This gas is not always present in the gas that people emit. The most typical connections include:

  • Nitrogen
  • Carbon dioxide
  • Oxygen
  • Hydrogen
  • Sometimes a small amount of methane.

Most people consider themselves overly carbonated, but this is rarely the case. It is normal to pass gas 14 to 23 times a day . If your gas has an unusually foul odor, this could be a major problem.

If you have a sulfuric burp, you have probably eaten something. Eating or drinking too fast can lead to excessive belching.

Some people may experience excess gas or sulfuric belching after eating certain foods. Other people can eat the same food and not have any gas.

This may be because the type and balance of intestinal bacteria is different for each person. Food also moves at different speeds through the digestive tract of different people.


For some people, these high-sulfur foods can increase the risk of sulfuric burps:

  • High protein foods
  • Eggs
  • Cheese
  • Whole milk

Other foods with lower sulfur content can cause excess gas in some people. These include foods that are high in sugar, starch, or soluble fiber.

Certain vegetables are known to cause gas as well, including:

  • Broccoli
  • Cauliflower
  • Brussels sprouts
  • Cabbage
  • Beans

Some artificial sweeteners can also cause excessive gas and bloating. Carbonated drinks and soft drinks are also offered.

Eating or consuming certain foods can lead to excessive belching. These include soft drinks and foods high in sulfur.


Certain medications can cause sulfuric burps. If you have recently started taking a new medicine, talk to your doctor.

Prevent sulfuric burps

The following tips will help prevent sulfuric burps:

  • Eat slowly to avoid swallowing air.
  • Avoid chewing gum and smoking. These actions can lead to swallowing excess air.
  • Avoid foods high in sulfur.
  • Avoid overeating. Instead of eating several very large meals, eat several small meals throughout the day.
  • Cut down on your alcohol intake. Alcoholic beverages can contain high amounts of sulfur.
  • Reduce or eliminate carbonated drinks.
  • Avoid foods high in sugar. Foods high in carbohydrates often cause excessive gas production. This is because the bacteria in your digestive tract feed on sugar. Bacteria in the intestines can also release hydrogen sulfide.
