Rotten Egg Burps (sulfur burps)

Belching is a common but usually socially unacceptable fact of life. It may happen a dozen times throughout the day, and many have rotten egg burps as a result. This form of expelled gas from the stomach may have a pungent odor depending on the foods consumed or medications ingested. Knowing how these sulfur burps occur may lead to a more successful way of treating and possibly preventing them.

It is important to remember that what causes such gas odor for one person may not produce the same results for you. Whether it is from that tasty burrito you ate or by accidentally swallowing gaps of air, continue reading if you’re wondering, “Why does my burp smell like rotten eggs?”


What Are Sulfur Burps or Rotten Egg Burps?

If you frequently say to yourself, “When I burp it smells like rotten eggs,” you may be suffering from sulfur burps. A burp occurs when gas or air escapes from the stomach through the mouth. Belching is another term for this.

Most burps have no smell or odor, but sometimes you may produce a rotten egg or sulfur smell. This type of burp is produced by a digestive gas called hydrogen sulfide, resulting from microbes in the small intestine or by the breakdown of certain foods in the stomach.

Foods such as meats, nuts, and green leafy vegetables like kale and broccoli contain a type of sulfur protein. Of course, consuming an actual egg will also produce “egg burps.”

Sulfur is an essential mineral for healthy connective tissue and prevents toxins such as harmful bacteria from damaging the cells.

What Causes Rotten Egg Burps?

In addition to food and carbonated beverages, burps that smell like eggs may be caused by certain medications and some health conditions.


Most of the sulfur within your body comes from the food you eat. Sulfur-containing proteins are transformed into essential amino acids for enzyme production and growth, as well as tissue preservation.

Sulfur foods include preservatives used in meals at restaurants and packaged goods such as guacamole. Eggs, red meat, poultry, fish, and dairy products contain sulfur. It is also found in vegetables such as cabbage, onions, asparagus, and sweet potatoes. Legumes like peas, beans, lentils, and alfalfa may also cause you to produce gas, as well as fruits like bananas, avocado, and watermelon.

Rotten egg burps may also occur after consuming grains and nuts, and beverages such as coffee, tea, and soda.

Eating Habits

The way you consume the foods you eat can also have a huge impact on whether burps smell like rotten eggs or not. In addition to the type of food you eat, such as sugar-laden or high-fat foods, the amount ingested can also play a role.

Eating a large meal forces the digestive tract to slow down and take longer to break down the food. The hydrogen sulfide in food can collect and remain in the abdomen before being expelled as burps.


Prescription medication is another reason that burps smell like rotten eggs. A combination of ingredients with cysteine or methionine amino acids may produce sulfur burps. These occur with medications that dissolve on their own within the digestive system.

It is best to discuss any drug that is causing the strange-smelling burps with your health team before stopping the medication.

Giardia Infection

Also known as giardiasis, a Giardia infection of the intestines may result in your having sulfur-smelling burps. Caused by the Giardia lamblia parasite, this type of infection is seen in areas with contaminated water. It is also contracted by direct contact with an infected person and consuming contaminated food.

Signs of a giardia infection may include diarrhea, severe stomach cramping, nausea, and bloating. The infection itself may last for several days.


This condition is characterized by egg-smelling burps, nausea, bloating, heartburn, and vomiting. It involves a slow emptying of the digestive tract within the stomach, which allows bacteria to develop. Food may also obstruct the digestive tract if it does not properly break down.

Gastroparesis may occur due to medications or health conditions that damage the nerves or abdominal muscles such as gastric surgery.

Irritable Bowel Syndrome (IBS)

IBS irritates the large intestine, also known as the colon. This disorder causes bloating, constipation, diarrhea, abdominal pain and gas. Sulfur burps are a common symptom.

Gastroesophageal Reflux Disease (GERD)

Commonly referred to as GERD, the condition causes rotten egg burps with heartburn, chest pain, or pressure on the chest.

GERD occurs when the lower esophageal sphincter between the esophagus and the stomach fails to close properly. This causes food or stomach acid to return to the esophagus.

Intestinal Bacteria

If your breath smells like sulfur, the cause may be a condition known as small intestinal bacterial overgrowth or SIBO. It occurs due to the overproduction of bacteria within the small intestine caused by digestive issues such as lactose intolerance, fructose malabsorption, celiac disease, and Crohn’s disease.

Other signs and symptoms include bloating, cramping, diarrhea, and flatulence.

Other Causes

Sulfur burps may also be caused by a gallbladder disorder or disease, an empty colon, extreme stress, and anxiety.
