Does garlic make you gassy?

Yes, garlic can make you gassy. Garlic contains high levels of fructans. Fructans can contribute to gas, bloating, and stomach pain.

The number of fructans present in garlic can further depend on whether you consume dried or fresh garlic. Dried garlic can contain more fructans compared to fresh garlic.

Individuals with fructan intolerance can experience fermentation in the gut which can result in bloating. This can lead to indigestion. 

Such individuals are advised to undergo an elimination diet. An elimination diet would include avoiding the consumption of foods that can cause bloating or symptoms of indigestion.

Can individuals suffering from GERD eat garlic?

GERD also called Gastroesophageal Reflux disease can occur when stomach acid enters your esophagus resulting in nausea or heartburn. If you suffer from GERD, it is better to consume garlic in moderation.

GERD can reduce the efficiency of LES (Lower Esophageal Sphincter). LES prevents the entry of acid back into the esophagus. 

However, in some individuals, the consumption of garlic might not cause any symptoms. In such instances, you can eat garlic.
