Why Your Stomach Swells After Eating?

Foods That Result in Gas Formation

Bloating occurs due to gas trapped in your intestines and stomach. After eating, the food gets digested in stomach and then goes into the small bowel, where carbohydrates and proteins present in the food are broken down by the enzymes to be used in the body as energy. Certain foods are hard to digest and may result in excessive gas, which may collect in your digestive system leading to belching, bloating and flatulence. Common gas forming foods are cauliflower, baked beans, carbonated beverages, broccoli, cabbage, vegetables and fruits and hard candy. Bloating can also occur due to swallowing of air from chewing gum or eating quickly.

Intolerance to Foods

Intolerance to certain kinds of foods is among the common causes of bloating of stomach. Bloating can be triggered by milk and foods containing gluten and fructose. It is recommended to not eat these foods in case you develop stomach pain or bloating after consuming them.

Though fiber forms an integral part of a diet that is promoted as healthy for heart; still, you should increase its amount gradually in your diet as it can result in bloating in some individuals.

2. Avoid eating excess salt: Eating excessive salt can result in water retention leading to bloating. Avoid excess salt by using herbs in your diet in place of salt. Also reduce the quantity of packaged and processed foods you consume.

3. Don’t eat fatty foods: Your body takes long time to process meals that are high in fat as the fat travels slowly in the digestive tract causing your body to bloat. However, more issues are caused by trans and saturated fats, which are present in fried foods; hence, you can try eating, unsaturated fats that are healthier such as nuts, seeds or avocado.

4. Limit your intake of carbonated drinks: Soda and carbonated water are the leading culprits when it comes to bloating of stomach. They cause the buildup of carbon dioxide gas in the body when you consume them. This leads to bloating, particularly if you consume them quickly. It is best to drink plain water. You may add a slice of lime or lemon for flavor.

5. Eat slowly: Eating quickly may lead to stomach bloating due to swallowing of air and retention of gas. You can reduce bloating by eating slowly which also reduces your intake of food.

6. Take a walk: Exercise has benefits for overall well-being and health. It also helps in reducing buildup of gas that result in bloating. You can go for a short walk post a meal to relieve bloating.

7. Take an anti-gas supplement: Anti-gas supplements such as a-galactosidase helps in preventing buildup of gas from some types of foods, relieving bloating. Many other types of digestive enzymes are available such as lipase, protease and amylase, which you can try. These help in breaking down fats, proteins and carbs and are either available as separate products or as combination products. Furthermore, probiotic supplements may help in regulation of the friendly bacteria present in the small intestine, which can also help in decreasing bloating.
