Introduction
When anxiety is excessive, the body releases stress hormones that stimulate increased or irregular gastrointestinal motility, leading to inadequate digestion and absorption of food in the intestines, resulting in increased gas production and consequently more flatulence. At the same time, anxiety may cause a person to unconsciously swallow excess air, further increasing intestinal gas. These issues typically improve as anxiety subsides.

Generally, excessive anxiety may lead to increased flatulence, which is related to the impact of anxiety on gastrointestinal function. If accompanied by other discomforts, other potential causes should be evaluated. If concerned, it is advisable to seek medical advice promptly. Detailed analysis is as follows:

When experiencing excessive anxiety, the body releases stress hormones that can accelerate or disrupt gastrointestinal motility. This may result in incomplete digestion and absorption of food in the intestines, leading to increased gas production and more frequent flatulence. Additionally, anxiety may cause unconscious swallowing of excess air, further increasing intestinal gas. These symptoms typically improve as anxiety subsides.

If increased flatulence is accompanied by symptoms such as abdominal pain, diarrhea, blood in stool, or unexplained weight loss, or if symptoms persist even after anxiety improves, the cause may involve other factors such as intestinal diseases or dietary issues rather than anxiety alone. Professional medical evaluation is necessary to identify the underlying cause and prevent missed diagnosis of health conditions.

If increased flatulence is linked to anxiety, it may be alleviated through relaxation techniques and dietary adjustments, such as reducing intake of gas-producing foods. However, if other symptoms are present or the condition persists, timely medical consultation is recommended to determine the exact cause and receive appropriate treatment.
