Why do i fart so much after eating?

0 votes
I am a 28 years old man. I have this embarassing habit of farting a lot when i eat anything. Another thing is that my farts are not that smelly but are noisy (loud) which causes utter shame if i am in public places. I really have to struggle hard to control my fart in order to excuse myself to get into a lonelier place.

My eating habits are pretty normal and timely, and mostly i have non spicy home cooked food. I rarely eat out. I have tried some antacids in the past but not much relief. Please let me know if there is anything i can do in order to overcome this?

The most probable cause of excessive gas without diarrhea is eating large amounts of foods high in soluble fiber. Spices by themselves usually do not cause gas, and antacids do not likely reduce it.

Typical foods that can cause excessive gas if eaten in large amounts are listed below.

Beans and Other Legumes

  • Beans
  • Lentils
  • Peas

Bread, Cereals

  • Whole-grain bread, oats, barley, psyllium husk, wheat bran and certain morning cereals are high in soluble fiber, which can cause bloating and gas.
  • Bread, pasta, noodles, pizza, bagels, pastries, cookies, which contain wheat, rye or barley, can trigger gas and diarrhea in individuals with celiac disease.

Dairy: Milk, Ice Cream, Cheese

Individuals with lactose intolerance can experience gas and diarrhea after drinking more than one cup of milk (or rarely less) or large amount of ice cream.


  • Apples
  • Apricots
  • Bananas
  • Figs
  • Grapefruit
  • Mango
  • Peaches
  • Pears
  • Plums
  • Strawberries

Sugars and Other Carbs

  • Foods high in fructose or sorbitol (certain fruits) can trigger gas and diarrhea in individuals with fructose malabsorption.
  • Sugars and other carbohydrate foods can trigger gas or diarrhea in individuals with intestinal parasitic infections or small intestinal bacterial overgrowth (SIBO).


  • Artichokes
  • Asparagus
  • Broccoli
  • Brussels sprouts
  • Cabbage
  • Carrots
  • Onions
  • Sweet potatoes
  • Turnips

Irritable Bowel Syndrome (IBS)

Individuals with irritable bowel syndrome can experience bloating, excessive gas or diarrhea few minutes after meals.

Infestation with Parasites (Food Poisoning)

Giardia or other intestinal parasite may cause bloating and flatulence for month after food poisoning. Diagnosis is made by a stool test. Treatment is with prescribed oral antiparasitic drugs.

Other Health Conditions with Excessive Gas

  • Fructose malabsorption
  • Lactose intolerance
  • Small intestinal bacterial overgrowth (SIBO)  due to various intestinal disorders, such as Crohn's disease.
  • Diagnosis of the above conditions is made by breath tests.
