Common stomach problems and how to deal with them vol.4(stomachtension)

"Stomach bloating" refers to the feeling of fullness or bloating in the whole or part of the stomach.

Generally, there are two types of bloating. ``My stomach is bloated and painful,'' ``I have a heavy stomach,'' and ``my stomach is rumbling,'' which are caused by gas buildup in the digestive tract. This is a feeling of fullness in the stomach caused by decreased motor function. In addition, abdominal bloating may be caused by fluid accumulation (ascites), inflammation or tumors within the abdominal cavity, or pregnancy.

Here we will discuss abdominal bloating due to gas.

Mechanism of abdominal bloating

Mechanism of abdominal bloating due to gas

Whenever a person eats a meal, gas is produced in the digestive tract. The accumulated gas is then periodically excreted as exhalation (breathing) or farting. At this time, the balance between gas production and excretion in the gastrointestinal tract is disrupted, and when excess gas accumulates in the intestinal tract, a feeling of bloating occurs. This is also called flatulence.

excess gas production


Symptoms include dysphagia, which causes people to swallow air abnormally when they are nervous or stressed, and autonomic nerve dysfunction. This is also the cause of the abdominal bloating and abdominal pain caused by irritable bowel syndrome (IBS), which is common these days.

Excessive production of intestinal gas

When bad bacteria increases due to changes in the intestinal flora, putrefactive gas is generated due to abnormal fermentation. Additionally, high-fiber and carbohydrate-rich foods tend to increase gas, and malabsorption and changes in the intestinal flora can lead to excess gas.

Reduced gas excretion

When the motility of the gastrointestinal tract decreases, the gas accumulated in the intestines cannot be excreted, leading to a feeling of bloating. This condition includes constipation and irritable bowel syndrome.

In addition, in intestinal obstruction, gas cannot be excreted along with the intestinal contents. Inflammation of the intestinal mucosa or circulation disorder causes gas to be absorbed by the body and cannot be excreted as exhalation, resulting in abdominal bloating.


Improving daily life

It occurs when the balance between gas production and excretion in the digestive tract is disrupted, so it is important to maintain a lifestyle that maintains a balance. As with constipation, try to improve your daily life. Take occasional breaks and take deep breaths to relax, eat less food that increases gas, chew your meals slowly, and avoid wearing tight belts or underwear.


intestinal regulator

Intestinal preparations containing lactic acid bacteria and bifidobacteria reduce the production of putrefactive gas by suppressing the growth of bad bacteria in the intestines. In addition, lactic acid and acetic acid produced by lactic acid bacteria stimulate the intestinal tract and increase peristalsis, which also promotes gas excretion.

Antifoaming agent

Dimethylpolysiloxane (dimethicone) has an antifoaming effect and is used medically to improve abdominal symptoms caused by gas in the gastrointestinal tract. Acts directly on gas in the gastrointestinal tract, promoting gas absorption and excretion.
