Mouth, esophagus (food pipe), stomach, and intestines (K00-K67; K90-K93).
- Achalasia (synonyms: esophageal motility disorder; esophageal achalasia; cardiaspasm; cardiaachalasia) – disorder belonging to the group of esophageal motility disorders. On the one hand, there is a relaxation disorder of the lower esophageal sphincter (UES; esophageal sphincter/gastric inlet), which means that the lower esophageal muscle does not relax during the swallowing process, and on the other hand, the motility (mobility) of the middle and lower esophageal muscles is impaired. As a result, the transport of the food pulp through the esophagus (esophagus) is disturbed.
- Functional dyspepsia (irritable stomach).
- Gastritis (inflammation of the gastric mucosa)
- Gastroesophageal reflux disease – frequent reflux (Latin refluere = flow back) of acidic gastric juice and other gastric contents into the esophagus (esophagus).
- Helicobacter pylori infection – Helicobacter pylori is a gram-negative, microaerophilic rod-shaped bacterium that colonizes the human gastrointestinal tract (GI tract) and can cause ulcers (ulcers) in the stomach and duodenum (stomach).
- Hiatal hernia (hiatal hernia).
- Ileus (intestinal obstruction)
- Zenker’s diverticulum, is a diverticulum of the hypopharynx (pharynx) and not the esophagus, as is often incorrectly stated; it is a pulsion diverticulum and pseudodiverticulum – bulging of the posterior wall of the pharynx at the junction with the esophagus
- Celiac disease (gluten allergy; gluten-induced enteropathy).
Neoplasms – tumor diseases (C00-D48)
- Gastric carcinoma (stomach cancer) – here: in addition to belching: Anorexia/appetence (loss of appetite); weight loss* , unexplained (weight loss); poor performance* .
- Esophageal cancer (cancer of the esophagus) – in this case: Dysphagia (difficulty swallowing; stenotic/”due to constriction”).
* Advanced tumor stage
Psyche – nervous system (F00-F99; G00-G99).
- Aerophagia (air swallowing) – Note that any active air regurgitation, i.e., choking down air and then regurgitating it with a belching sound, brings more air into the stomach; the same is true of increased salivation, which likewise promotes aerophagia.
- Mental stress
Symptoms and abnormal clinical and laboratory findings not elsewhere classified (R00-R99).
- Meteorism (flatulence)
- Heartburn (pyrosis)
Other differential diagnoses
- Nutrition
- Wrong eating habits like.
- Hasty eating, not chewing enough and talking a lot during meals (= swallowing a lot of air)
- Distract at the table with television, reading or smartphone
- Eating fewer large, high-fat and/or sweet meals.
- Foods that can release gases already in the stomach: Yeast products, legumes, peppers, whole grains, coffee.
- Drinking carbonated drinks (eg carbonated mineral water, sodas).
- Last food intake late in the evening before bed rest
- Wrong eating habits like.
- Pleasure food
- Alcohol consumption (this makes the sphincter between the esophagus and stomach slacken, which is like a valve to prevent stomach acid from rising)
- Tobacco (smoking)
- Physical activity
- Lack of physical activity (lack of exercise).
- Psycho-social situation
- Stress
- Pregnancy – Pregnancy hormones cause the muscles of the gastrointestinal tract (gastrointestinal tract) to relax, thus opening the sphincter (sphincter) between the stomach and esophagus (esophagus). In late pregnancy, moreover, the uterus (womb) and fetus press on the stomach from below, so that regular belching becomes the norm.
