Common Causes of Abdominal Pain and Vomiting
Abdominal pain and vomiting are symptoms with a wide range of possible causes. The most frequent sources are disorders of the gastrointestinal (GI) system, but gynecologic, urinary, and even neuromuscular conditions can also be responsible. Vomiting often points toward a GI origin, but a thorough evaluation is needed to identify the exact cause. Important factors include the pain’s location, timing, severity, and any aggravating or relieving factors, as well as the patient’s medical, surgical, and reproductive history Kara2018Ehrlich2019.
Gastrointestinal Causes
The GI tract is the most common source of abdominal pain and vomiting. Typical causes include:
- Gastroenteritis (infections of the stomach and intestines)
- Bowel obstruction (blockage in the intestines), which can be due to adhesions from previous surgeries, hernias, or tumors. Signs include abdominal distension, high-pitched bowel sounds, and lack of stool or gas passage Mahmood2024Chen2021Klausner2019.
- Pancreatitis (inflammation of the pancreas), which can also lead to complications like bowel obstruction .
- Peptic ulcer disease (ulcers in the stomach or duodenum)
- Gastritis (stomach lining inflammation)
- Cholecystitis (gallbladder inflammation) .
Less Common and Rare Causes
Some less frequent but important causes include:
- Acute esophageal necrosis (“black esophagus”), a rare condition often linked to low blood flow states such as diabetic ketoacidosis, leading to severe esophageal injury .
- Chronic abdominal wall pain, which can directly or indirectly cause persistent nausea and vomiting. This may be overlooked if only GI causes are considered .
- Cannabinoid hyperemesis syndrome (CHS), especially in people with diabetes who use cannabis, can mimic other GI conditions like diabetic gastroparesis .
- Psychogenic vomiting, which can be associated with rare complications such as spontaneous pneumomediastinum (air in the chest cavity) .
Non-Gastrointestinal Causes
While GI causes are most common, other systems can be involved:
- Gynecologic conditions (e.g., ectopic pregnancy, ovarian torsion) should be considered, especially in women of childbearing age .
- Urinary tract issues (e.g., urinary tract infection, kidney stones)
- Metabolic or systemic conditions (e.g., diabetic ketoacidosis, medication side effects) Rubinov2014Aung2021.
Diagnostic Approach and Complications
A careful history and physical exam are essential to narrow down the cause. Imaging and laboratory tests may be needed to confirm the diagnosis. Persistent vomiting can lead to complications such as dehydration, electrolyte imbalances, and, in severe cases, tears or ruptures in the GI tract (e.g., Mallory-Weiss tear, Boerhaave syndrome) .
Conclusion
Abdominal pain and vomiting have many possible causes, most commonly from the GI tract but also from other organ systems. A thorough evaluation, considering both common and rare causes, is crucial for accurate diagnosis and effective treatment. Recognizing less typical sources, such as abdominal wall pain or cannabinoid hyperemesis syndrome, can prevent misdiagnosis and unnecessary procedures Kara2018Kapural2016Ehrlich2019+6 MORE.
