Noise in the belly: what it can be and what to do

The noises in the belly, also called borborygmus, is a normal situation and is most often indicative of hunger, since due to the increase in the amount of hormones responsible for the feeling of hunger, there is contraction of the intestine and stomach, resulting in the noises.

In addition to hunger, noises can also be a consequence of the digestive process or the presence of gases. However, when the noises are accompanied by other symptoms such as pain and enlargement of the abdomen, for example, it can be indicative of infections, inflammation or intestinal obstruction, and it is important to go to the doctor so that tests are carried out to identify the cause and start treatment. suitable.


What can be

Noises in the belly are normal, especially after a meal, as the walls of the intestine contract to facilitate the passage of food and favor digestion. These noises can appear while the person is awake or even during sleep, in addition to being heard or not.

For there to be noises, the walls of the intestine must contract and there must be liquid and/or gases in the intestine. Thus, the main causes of belly noises are:

1. Hunger

Hunger is one of the main causes of belly noise, because when we feel hungry there is an increase in the concentration of some substances in the brain that guarantee the feeling of hunger and that send signals to the intestine and stomach, inducing contraction of these organs and leading to the emergence of noises.

What to do: When hunger is the cause of stomach noises, the best thing to do is to eat, giving preference to he althy foods rich in fiber to favor bowel movement and digestion.

2. Gases

The presence of a greater amount of gas in relation to the amount of liquid that passes through the digestive system also leads to the appearance of noises.

What to do: In these cases it is important to have a diet low in foods that cause gas, such as beans and cabbage, for example, as they ferment a lot during the digestive process and increase the amount of gases produced in the body, which results in noises.

3. Gastrointestinal Infections and Inflammations

Noises can also happen due to infections and intestinal inflammation, especially in the case of Crohn's disease. In these cases, in addition to borborygmus, other symptoms usually appear, such as abdominal pain and discomfort, malaise, vomiting, nausea and diarrhea.

What to do: As soon as these symptoms appear, it is important to go to the emergency room or hospital to avoid dehydration, nutritional deficiencies or other complications. In addition, it is important to rest, have a he althy diet and use medication only if indicated by the doctor.

4. Intestinal obstruction

Intestinal obstruction can also lead to the emergence of noises in the belly, because due to the difficulty of passing liquids and gases through the intestinal tract, the intestine itself increases the amount of perist altic movements to facilitate the passage of these liquids and gases, also leading to increased noise.

Intestinal obstruction can have several causes, such as the presence of worms, intestinal endometriosis, inflammatory diseases and the presence of hernias, for example, with not only noises in the belly but also other symptoms, such as abdominal pain, very strong colic, decreased appetite and nausea, for example. Learn more about intestinal obstruction.

What to do: Treatment for intestinal obstruction varies according to the cause, and it is important that it is done in the hospital to avoid complications.

5. Hernia

A hernia is a situation characterized by the exit of a part of the intestine out of the body, which can result in intestinal obstruction and, consequently, in the belly noises. In addition, other symptoms may arise, such as pain, swelling, local redness, nausea and vomiting.

What to do: It is recommended that the person immediately go to a surgeon so that the severity of the hernia is evaluated and surgery is considered to avoid complications such as the strangulation of some organ in the abdominal region, which leads to reduced blood circulation to the site and, consequently, necrosis. See how the treatment for abdominal hernia should be done.

When to go to the doctor

It is recommended to go to the doctor when, in addition to intestinal noises, other symptoms arise, such as:

  • Pain;
  • Augmentation of the abdomen;
  • Fever;
  • Nausea;
  • Vomiting:
  • Frequent diarrhea or constipation;
  • Presence of blood in the stool;
  • Fast weight loss with no apparent cause.

The general practitioner or gastroenterologist, according to the symptoms described by the person, may indicate the performance of some tests, such as computed tomography, endoscopy and blood tests so that the cause of the symptoms can be identified and can be started the most appropriate treatment.
