Sudden Abdominal Pain – Causes, Symptoms, Treatment. Stomach Pain on an Empty Stomach

Unpleasant sensations or sharp pain localized in the upper abdominal region, known as the epigastrium, may indicate a wide spectrum of disorders—ranging from transient issues linked to poor dietary choices or ingestion of irritating substances to chronic and severe organic conditions. Accurate identification of the pain’s origin is not only pivotal for symptom alleviation but also for preventing recurrence and implementing targeted treatment if the underlying cause is a medical condition requiring intervention. Early recognition of the triggering factor also facilitates lifestyle modifications or dietary adjustments, which can significantly enhance the patient’s quality of life.

A thorough diagnostic assessment of epigastric pain necessitates a meticulous patient history and physical examination, with a focus on key pain attributes: localization, temporal pattern (acute vs. chronic), qualitative characteristics, severity, and modulating factors. While gastric pain is frequently attributable to dietary indiscretions, food poisoning, or infections, it more commonly serves as a nonspecific manifestation of numerous underlying conditions, with its perception being inherently subjective and contingent upon individual patient variables and contextual circumstances. The most prevalent etiologies of abdominal pain include inflammatory disorders and conditions associated with mucosal damage (e.g., peptic ulcer disease of the stomach and duodenum) [4]. A burning, searing discomfort typical of esophageal pathologies (Table 1)—often accompanied by retrosternal burning and gastroesophageal reflux—is exacerbated in the supine position, during forward bending, and following consumption of large meals. Conversely, a dull, gnawing epigastric pain occurring 1–3 hours postprandially may indicate ulcerative disease. Following the exclusion of organic causes, functional disorders—including so-called gastroenterological neurosis (emotional gastric disorder)—should be considered. Of particular clinical importance is the early detection of gastric cancer, an insidious condition that in its initial stages rarely presents with pathognomonic symptoms such as premature satiety, postprandial fullness, epigastric discomfort, nausea, belching, or weight loss—symptoms that may also occur in other diseases. Table 1 delineates the etiologic differentiation of gastric pain, highlighting characteristic features and associated symptoms.

The sensation commonly referred to as "hunger pains"—characterized by burning, stabbing, or gnawing discomfort localized in the epigastric region—serves as a hallmark symptom of gastric mucosal inflammation (gastritis) and peptic ulcer disease affecting the stomach or duodenum [2]. These painful episodes typically intensify during nocturnal hours and early morning periods (i.e., in a fasting state), as well as within 1 to 3 hours following meal consumption. In ulcerative conditions, symptoms generally abate after eating—due to the buffering effect of food on excessive gastric acidity—or upon administration of acid-neutralizing antacids or proton pump inhibitors that suppress hydrochloric acid secretion [2]. Comprehensive management extends beyond pharmacotherapy to encompass dietary modifications: exclusion of indigestible foods (high-fat or fried dishes), avoidance of irritant substances (caffeine, alcohol, spicy seasonings, pickled products), and elimination of rushed eating habits. Sudden, excruciating pain described as "tearing" or "dagger-like" may indicate a severe complication—ulcer perforation—and necessitates emergency surgical evaluation.

Pain originating from the stomach seldom presents as an isolated symptom; instead, it is most commonly accompanied by a constellation of additional complaints, which may include recurrent nausea, vomiting episodes, diarrheal disturbances, a retrosternal burning sensation commonly referred to as heartburn, and excessive gas accumulation within the gastrointestinal tract, manifesting as abdominal distension. These associated symptoms serve as critical diagnostic indicators, enabling healthcare providers to systematically ascertain the underlying pathogenesis of the pain. Particular attention must be directed toward cases in which gastric discomfort is accompanied by alarming red-flag symptoms, such as gastrointestinal bleeding (evidenced by melenic or hematochezia stools), progressive anemia of unclear etiology, or unexplained weight loss—phenomena that may signify the presence of chronic inflammatory conditions, erosive or ulcerative mucosal damage within the stomach, or even a neoplastic process affecting this organ [2].

Pinpointing the underlying cause of gastric pain constitutes the cornerstone of effective therapeutic intervention, facilitating the selection of personalized treatment modalities tailored to each patient’s specific needs. The primary objective should focus on eradicating the root cause of the discomfort, a strategy that frequently results in sustained health improvement [2]. The pharmaceutical sector provides an extensive array of medicinal options for this purpose—ranging from conventional analgesic agents (such as paracetamol or opioid derivatives) and antispasmodic medications to antidepressant drugs employed in cases of chronic neuropathic pain. When causal treatment proves unfeasible, symptomatic management becomes essential, aiming to alleviate pain severity and substantially enhance patients’ overall quality of life [2]. Complementary approaches based on herbal medicine are gaining increasing recognition for their efficacy in mitigating gastric discomfort, leveraging the soothing properties of botanicals such as chamomile, ginger root, peppermint leaves, flaxseeds, and plantain—available both as single-ingredient preparations and as meticulously formulated herbal blends. It is critical to acknowledge that acute abdominal pain may serve as a clinical manifestation of diverse conditions, spanning from benign, self-resolving episodes to emergencies necessitating immediate surgical intervention, thereby presenting a complex diagnostic dilemma [3]. While gastric pain often stems from dietary indiscretions, excessive consumption of heavy meals, or chronic stress, persistent somatic pain of sudden onset or prolonged visceral pain lasting months may indicate serious underlying gastrointestinal pathologies. Any concerning, prolonged pain of unclear etiology warrants prompt evaluation by a medical specialist to facilitate comprehensive diagnostic assessment.
