What causes constant bloating and belching?

Generally, persistent bloating and belching may be caused by non-pathological factors such as exposure to cold air, or by pathological conditions such as indigestion or acute gastroenteritis. Patients can receive symptomatic treatment based on the specific cause. Detailed analysis is as follows:

1. Non-pathological factors

If exposed to cold air during meals, the diaphragm may go into spasm, causing food to remain in the stomach for prolonged periods, leading to symptoms such as abdominal distension and belching. This is a normal physiological response that does not require special treatment and usually resolves spontaneously after a short time.

2. Pathological factors

1) Indigestion
Frequent overeating or binge eating may irritate the gastrointestinal mucosa, causing gastrointestinal dysfunction and slowed intestinal motility, thereby resulting in bloating. Additionally, when food remains in the stomach for too long, it may trigger belching during digestion. It is recommended that patients take medications such as Baohe Pills or Jianwei Xiaoshi Tablets under medical guidance, while also adjusting their dietary habits to avoid overeating.

2) Acute gastroenteritis
Poor dietary hygiene, such as consuming contaminated food, may allow bacterial invasion, triggering an inflammatory response. Inflammation irritates gastrointestinal tissues, leading to symptoms including bloating, acid reflux, and nausea. Patients are advised to take medications such as bismuth potassium citrate capsules or montmorillonite powder under medical supervision, along with improved attention to food hygiene.

In addition to the above three causes, persistent bloating and belching could also result from other conditions, such as rectal cancer. Therefore, patients should seek appropriate symptomatic treatment according to the underlying cause.
