Common Causes of Stomach Pain
Stomach pain, also known as abdominal pain, can have many causes, ranging from mild to life-threatening. The most frequent causes include functional abdominal pain disorders (FAPDs), such as irritable bowel syndrome and functional dyspepsia, which are often diagnosed when other causes are ruled outSinha2022Mizuno2020Drewes2020. Inflammation of the intestines, distention or blood loss to abdominal organs, and infections like Helicobacter pylori or Yersinia can also lead to stomach painSinha2022Mizuno2020Drewes2020+1 MORE.
Other common causes include gastroesophageal reflux disease (GERD), peptic ulcers, chronic pancreatitis, inflammatory bowel diseases (such as Crohn’s disease and ulcerative colitis), and gallstonesMizuno2020Polunina2020Lukić2021+1 MORE. Acute causes may involve gastrointestinal, urological, gynecological, genitourinary, or vascular issues, making a thorough history and examination essential for diagnosisAllen2023Abd-Elsayed2019.
Less Common and Rare Causes of Stomach Pain
Some rare causes of stomach pain include COVID-19-related multisystem inflammatory syndrome (PIMS-TS), familial Mediterranean fever, and the presence of foreign bodies in the stomach, such as accidentally swallowed bones, which can cause obstruction or injurySinha2022Musa2021. Chronic abdominal pain can also be due to less typical conditions, such as narcotic bowel syndrome or chronic abdominal wall pain.
Mechanisms and Types of Stomach Pain
Stomach pain can be nociceptive (from tissue injury), neuropathic (from nerve injury), or related to cancer. Often, more than one mechanism is involved in a single patient. The pain may be accompanied by other symptoms like nausea, vomiting, fever, or changes in bowel habits, depending on the underlying causePolunina2020Lukić2021.
Diagnostic Approach to Stomach Pain
Diagnosing the cause of stomach pain requires a careful review of symptoms, physical examination, and sometimes laboratory tests, imaging (like ultrasound or CT scans), and endoscopic proceduresAllen2023Polunina2020Abd-Elsayed2019. The location, intensity, and timing of the pain, as well as associated symptoms, help narrow down the possible causesAllen2023Lukić2021.
Conclusion
Stomach pain has a wide range of possible causes, from common functional disorders and infections to rare conditions and foreign body ingestion. Accurate diagnosis depends on a thorough clinical evaluation and, when necessary, additional tests. Understanding the variety of causes is crucial for effective management and treatmentSinha2022Mizuno2020Allen2023+6 MORE.
