Stomach Pain

Stomach pain, or abdominal pain, refers to discomfort or pain felt anywhere between the chest and the pelvis. It is an extremely common complaint that can range from a mild, temporary ache to severe pain requiring emergency medical attention. Because the abdomen contains many organs including the stomach, intestines, liver, gallbladder, pancreas, and kidneys, the location, quality, and timing of abdominal pain can provide important clues about its origin. Abdominal pain can be categorized in several ways: by location (upper, lower, left, right, or generalized), by onset (sudden or gradual), by character (sharp, dull, crampy, or burning), and by duration (acute or chronic). Functional disorders like irritable bowel syndrome and indigestion account for a large proportion of chronic abdominal pain, while acute causes range from benign conditions like gas and constipation to emergencies like appendicitis and bowel obstruction. Many cases of stomach pain are temporary and related to diet, stress, or minor gastrointestinal disturbances. However, severe or persistent abdominal pain, especially when accompanied by fever, vomiting, inability to eat, blood in the stool, or significant tenderness, warrants prompt medical evaluation. Keeping track of when pain occurs, what makes it better or worse, and any associated symptoms can help your healthcare provider make an accurate diagnosis.

Common Causes of Stomach Pain

Indigestion (Dyspepsia)

Indigestion is a general term for discomfort in the upper abdomen, often described as a feeling of fullness, bloating, burning, or gnawing pain during or after eating. It can be triggered by eating too quickly, consuming fatty or spicy foods, overeating, stress, or certain medications like NSAIDs. Most cases of indigestion are not a sign of serious disease and can be managed with dietary modifications, eating smaller meals, and over-the-counter antacids.

Gastritis

Gastritis is inflammation of the stomach lining that can cause upper abdominal pain, nausea, vomiting, and a feeling of fullness or burning in the upper abdomen. It can be caused by chronic use of NSAIDs, excessive alcohol consumption, Helicobacter pylori bacterial infection, or autoimmune conditions. Treatment depends on the cause and may include acid-reducing medications, antibiotics for H. pylori infection, and avoiding stomach irritants.

Irritable Bowel Syndrome (IBS)

IBS is a chronic functional gastrointestinal disorder affecting the large intestine, causing recurrent abdominal pain or cramping associated with changes in bowel habits such as diarrhea, constipation, or alternating between both. The pain often improves after a bowel movement and may be triggered by certain foods, stress, or hormonal changes. While there is no cure for IBS, symptoms can be managed through dietary changes (such as a low-FODMAP diet), stress management, regular exercise, and sometimes medication.

Food Intolerance

Food intolerances, such as lactose intolerance or sensitivity to gluten, fructose, or FODMAPs, can cause stomach pain, bloating, gas, and diarrhea after consuming trigger foods. Unlike food allergies, which involve the immune system, food intolerances typically involve difficulty digesting certain substances. Identifying trigger foods through an elimination diet and avoiding them is the primary management strategy.

Peptic Ulcer

Peptic ulcers are open sores that develop on the inner lining of the stomach or the upper portion of the small intestine, causing a burning or gnawing pain in the middle or upper abdomen that may worsen between meals or at night. The two most common causes are H. pylori bacterial infection and long-term use of NSAIDs like ibuprofen or aspirin. Treatment typically involves acid-reducing medications (proton pump inhibitors) and antibiotics if H. pylori is present.

Appendicitis

Appendicitis is inflammation of the appendix, a small pouch attached to the large intestine, that typically begins with dull pain around the navel that migrates to the lower right abdomen and becomes increasingly sharp and severe. It is often accompanied by fever, nausea, vomiting, and loss of appetite, and the pain typically worsens with movement, coughing, or sneezing. Appendicitis is a surgical emergency that usually requires prompt removal of the appendix (appendectomy) to prevent rupture.

Gallstones

Gallstones are hardened deposits of bile that form in the gallbladder and can cause sudden, intense pain in the upper right abdomen or center of the abdomen (a gallbladder attack), often after eating a fatty meal. The pain may radiate to the right shoulder or back and can last from minutes to several hours. While many people with gallstones have no symptoms, those experiencing recurrent attacks may need surgical removal of the gallbladder (cholecystectomy).

Constipation

Constipation, defined as having fewer than three bowel movements per week or straining to pass hard, dry stools, can cause significant abdominal discomfort, bloating, and cramping. It is commonly caused by insufficient fiber intake, inadequate hydration, lack of physical activity, certain medications, and ignoring the urge to have a bowel movement. Increasing dietary fiber, drinking more water, exercising regularly, and establishing a routine bowel habit can usually resolve constipation.

When to See a Doctor

Seek medical attention if you experience any of the following:

  • Severe abdominal pain that comes on suddenly
  • Pain accompanied by fever, persistent vomiting, or inability to keep food down
  • Blood in vomit or stool, or black, tarry stools
  • Abdominal pain with significant bloating or distension that does not improve
  • Pain in the lower right abdomen that worsens with movement
  • Abdominal pain accompanied by yellowing of the skin or eyes (jaundice)
  • Persistent stomach pain lasting more than a few days without improvement
  • Unexplained weight loss accompanied by abdominal pain

Home Remedies & Self-Care

1

Peppermint Tea

Peppermint has natural antispasmodic properties that can help relax the smooth muscles of the digestive tract, reducing cramping and bloating. Drinking a cup of peppermint tea after meals can aid digestion and provide relief from stomach discomfort. However, peppermint may worsen symptoms in people with GERD, as it can relax the lower esophageal sphincter and allow acid reflux.

2

Heat Therapy

Applying a warm heating pad or hot water bottle to the abdomen can help relax tense muscles, improve blood flow, and reduce pain from cramps, gas, and indigestion. Use the heat source for 15 to 20 minutes at a time with a cloth barrier to protect the skin. This simple remedy can provide surprisingly effective relief for many types of abdominal discomfort.

3

BRAT Diet

When experiencing stomach pain with nausea or diarrhea, eating bland, easy-to-digest foods like bananas, rice, applesauce, and toast can help settle the stomach without irritating it further. These foods are low in fiber, fat, and seasoning, making them gentle on a sensitive digestive system. Gradually reintroduce other foods as symptoms improve, starting with simple, plain options before returning to your regular diet.

4

Ginger

Ginger has well-documented properties that can help relieve nausea and reduce inflammation in the digestive tract. Fresh ginger sliced into hot water to make tea, or chewing on a small piece of fresh ginger, can help alleviate stomach pain and nausea. Studies suggest that ginger promotes gastric motility, helping food move more efficiently through the digestive system.

5

Gentle Movement and Positioning

Light physical activity such as a gentle walk can help stimulate digestion and relieve gas and bloating. If movement is too uncomfortable, lying on your left side can help reduce acid reflux, while drawing your knees to your chest can help release trapped gas. Avoid lying flat on your back immediately after eating, as this can worsen indigestion and reflux.

Frequently Asked Questions

Several features of stomach pain can indicate a serious or potentially life-threatening cause. Pain that is sudden, severe, and constant (rather than coming and going) may suggest a surgical emergency like appendicitis, perforation, or bowel obstruction. Pain accompanied by high fever, persistent vomiting, inability to pass gas or stool, blood in the stool or vomit, abdominal rigidity (a very hard, tense abdomen), or signs of shock (lightheadedness, rapid pulse, pale skin) requires immediate medical attention. Pain in the lower right abdomen that started around the navel and progressively worsened is the classic pattern for appendicitis. When in doubt, seek medical evaluation -- it is always better to be assessed and reassured than to delay treatment for a serious condition.
The location of abdominal pain provides important diagnostic clues. Upper right pain may suggest gallbladder problems or liver issues. Upper middle pain is common with gastritis, peptic ulcers, and pancreatitis. Upper left pain is less common but can relate to the spleen or stomach. Lower right pain is the classic location for appendicitis. Lower left pain may indicate diverticulitis or constipation. Pain around the navel can suggest early appendicitis, small bowel problems, or umbilical hernia. Generalized pain that affects more than half the abdomen may suggest a viral illness, gas, or more serious conditions like bowel obstruction or peritonitis. However, these are general guidelines, and many conditions can present with atypical pain locations.
Yes, stress is a well-established cause of stomach pain through the gut-brain axis, a bidirectional communication system between the central nervous system and the enteric nervous system of the gut. Stress can increase stomach acid production, alter gut motility, increase intestinal permeability, and change the gut microbiome, all of which can contribute to abdominal pain. Conditions like irritable bowel syndrome and functional dyspepsia are particularly sensitive to stress, and many people notice their digestive symptoms worsen during stressful periods. Managing stress through regular exercise, adequate sleep, mindfulness practices, and therapy can significantly improve stress-related digestive symptoms.
A typical stomachache from indigestion, gas, or a viral illness tends to be relatively mild, comes and goes, is often generalized or centered around the navel or upper abdomen, and usually resolves within hours to a day or two. Appendicitis, by contrast, typically begins as a dull ache around the navel that progressively migrates to the lower right abdomen over 6 to 12 hours, becoming sharper and more severe. Appendicitis pain tends to worsen steadily rather than fluctuate, is aggravated by movement or coughing, and is often accompanied by loss of appetite, low-grade fever, nausea, and sometimes vomiting. If you suspect appendicitis, seek emergency medical care, as a ruptured appendix can lead to life-threatening peritonitis.
Seek emergency care for stomach pain that is sudden and severe, especially if it feels like the worst abdominal pain you have ever experienced. Other reasons to go to the ER include stomach pain with high fever, persistent vomiting (especially if the vomit contains blood or looks like coffee grounds), blood in the stool or black tarry stools, signs of dehydration, abdominal distension with inability to pass gas or stool, pain in the lower right abdomen suggesting appendicitis, or abdominal pain in the setting of recent abdominal surgery or known abdominal conditions. Pregnant women with severe abdominal pain should also seek immediate evaluation to rule out complications like ectopic pregnancy.
