Frequent flatulence in the morning that is not smelly

Passing gas frequently in the morning without a foul odor may be caused by physiological factors or pathological conditions such as functional constipation, irritable bowel syndrome (IBS), etc. Appropriate management should be based on specific circumstances. Detailed analysis is as follows:

I. Physiological Factors

If one eats before bedtime while laughing loudly or chewing gum, it may lead to swallowing excess air during the process. This swallowed air can accumulate in the stomach. Upon waking in the morning, increased gastrointestinal motility helps expel the trapped gas, resulting in frequent passing of odorless gas. This is considered a normal phenomenon.

II. Pathological Factors

1. Functional Constipation

If daily food intake is insufficient, undigested food residues remain in the intestines and fail to adequately stimulate the intestinal wall, leading to weakened intestinal motility and subsequent functional constipation. Prolonged retention of intestinal contents may allow gut bacteria to break them down and ferment them, producing gas and causing increased flatulence. It is recommended to maintain adequate dietary intake. If symptoms persist over time, medications such as lactulose oral solution or glycerin suppositories (e.g., Kaisailu) may be used under medical guidance.

2. Irritable Bowel Syndrome (IBS)

This condition is primarily associated with psychological factors and inflammatory stimulation. If a patient experiences prolonged mental stress or has a history of intestinal infection, the intestinal mucosa may become irritated, altering its permeability and leading to intestinal dysfunction characteristic of IBS. In such cases, increased intestinal motility and changes in stool consistency may also result in frequent flatulence. Patients may take medications such as atropine sulfate tablets or probiotic capsules as directed by a physician.

In addition, this symptom could also be caused by lactose intolerance, short bowel syndrome, or inflammatory bowel disease. It is advisable to maintain regular作息 (daily routines), emotional stability, and avoid spicy or irritating foods. During meals, one should chew slowly and avoid talking loudly.
