Burping a lot and noticing a bloated belly can be a sign of a lack of stomach acid or other digestive disorders. Changing some habits can help.

Sometimes after eating, we can feel a bloated belly and really want to burp. When this happens with some frequency, it is convenient to investigate the possible causes of this abdominal distention and continuous belching.


One of the main causes of belching that occurs frequently after eating is a lack of hydrochloric acid in the stomach, which can be verified with a simple bicarbonate test.

To function optimally, our stomach needs to have a very low pH, that is, it must have a very acidic environment, and this is achieved thanks to a sufficient production of hydrochloric acid. In fact, although it seems paradoxical, people who suffer from heartburn or heartburn usually do not produce enough stomach acid.

Having enough acid in the stomach helps to assimilate nutrients, such as iron, zinc, calcium, and vitamins such as B12 or folic acid. It also ensures the digestion of proteins, which in the absence of hydrochloric acid cost more to digest.

In turn, the presence of hydrochloric acid in the stomach limits the entry of bacteria and parasites into the digestive system, and prevents bacteria present in the intestine from migrating to the stomach.

However, the stomach can lose the ability to produce enough hydrochloric acid due to factors such as stresseating too fast, taking certain medications, or even lack of rest.

The after eating burping they indicate that bacteria are fermenting ingested food. In the absence of hydrochloric acid, some bacteria survive in the less acidic environment of the stomach, which can ferment food and generate gas. These stomach gases are what cause you to burp a lot.

If hours after eating, you tend to burp a lot and the taste of some food is noticeable in your mouth, it means that the food is still in the stomach, when it should have reached the intestine. This is an indicator of poor digestion and also low hydrochloric acid formation in the stomach.

The abdominal distention after eating may be due to bacterial overgrowth in the stomach or small intestine, a condition also known as SIBO . With little acid, there are bacteria in places where they should not be and food remains in contact with them longer, thus fermenting and causing gas and bloating.


To improve both situations it can help to drink a little warm water with the juice of half a lemon or with mandarin juice before the three main meals, as it helps to acidify the pH of the stomach.

It is also important to dedicate at least 30 minutes to each meal and eat in a calm environment, in a relaxed way. You can take a couple of deep breaths before eating , putting your full attention on the air coming in and out of your nose, to activate the parasympathetic system and reduce your stress levels.

Chewing well is another essential habit. We need to chew well to activate all the mechanisms of good digestion: it helps us to salivate food and to facilitate the work of the stomach. We can, for example, follow the advice of Traditional Chinese Medicine, which recommends chewing each bite up to 200 times. The stomach meridian passes through the lower jaw, so by chewing food well, we facilitate the function of this organ.

If, in addition to burping, you have a lot of abdominal distention and you find that you have bacterial overgrowth, it is advisable to go to the doctor and an integrative nutritionist to add an antibiotic therapy to all these measures.
