Stomach Pain: Possible Causes, Red Flags & When to Seek Care

Stomach pain, medically referred to as abdominal pain, is discomfort felt anywhere in the region between your chest and groin. It is a very common symptom that can range from a mild, temporary belly ache to severe, acute pain. The abdomen contains many organs, including the stomach, intestines, liver, gallbladder, pancreas, and appendix. Pain in this area can be caused by digestion issues, inflammation, infections, or organ blockages. Identifying the exact location of the pain, its severity, and accompanying symptoms can help you and your doctor narrow down the possible causes.

What stomach pain may feel like

Stomach pain can present in several ways. It may feel like generalized, dull cramping throughout your abdomen, often accompanied by bloating, gas, or bowel changes. It can present as a sharp, constant, localized pain in a specific area (such as the lower right side or upper left side) that worsens when you move or press on the area. You might experience a burning sensation in your upper abdomen (heartburn) or a deep, aching pain that radiates to your back or chest.

Common possible causes of stomach pain

The following are common reasons someone might experience this symptom. This list is for educational context only and does not represent a diagnosis. A proper clinical assessment is required to identify the root cause.

Indigestion or Gas

Temporary buildup of gas in the digestive tract or irritation of the stomach lining, often caused by eating fatty, spicy, or gassy foods, eating too quickly, or carbonated beverages.

Why it may fit: Fits if you have mild, generalized cramping, bloating, or stomach pressure that improves after passing gas or having a bowel movement.

When to seek care: Manage with dietary adjustments, walking, or over-the-counter gas relievers. Consult a clinician if the pain becomes localized or severe.

Gastroenteritis (Stomach flu)

A viral or bacterial infection of the stomach and intestines, commonly leading to inflammation, cramps, and fluid loss.

Why it may fit: Fits if you have moderate, crampy abdominal pain accompanied by diarrhea, nausea, vomiting, and a low-grade fever.

When to seek care: Focus on hydration with small sips of water or electrolyte solutions. Consult a doctor today if vomiting prevents keeping liquids down for 24 hours or if you see blood in your stool.

Irritable bowel syndrome (IBS)

A chronic gastrointestinal disorder characterized by a group of symptoms, including recurring stomach pain and changes in bowel movements.

Why it may fit: Fits if you experience recurring abdominal cramps, bloating, and gas that are frequently relieved by bowel movements, and are accompanied by periods of diarrhea or constipation.

When to seek care: Consult a primary care doctor or gastroenterologist for long-term lifestyle, dietary, and medical management options.

Red flags: when to seek urgent care

Urgent Medical Attention Required

Certain symptoms can indicate a serious or life-threatening condition that requires immediate medical evaluation. Seek emergency care (call 911 or visit the nearest ER) if you experience stomach pain alongside any of the following signs:

⚠ Severe abdominal pain that starts suddenly and worsens rapidly
⚠ Stomach pain accompanied by a high fever and persistent vomiting
⚠ Abdomen that is swollen, tender, rigid, or hard to the touch
⚠ Stomach pain with bloody vomit or bloody/black, tarry stools
⚠ Pain localized to the lower right abdomen, especially if tender when pressed (sign of appendicitis)
⚠ Stomach pain accompanied by yellowing of the skin or eyes (jaundice)

What to track before seeing a doctor

To help your healthcare provider make a more accurate diagnosis, it is highly recommended to monitor and record detailed information about your symptom. Use this checklist as a guide:

✓ Note the exact location of the stomach pain (upper, lower, right side, left side).
✓ Track what you eat, when you eat, and how it correlates with the onset or improvement of pain.
✓ Monitor your bowel habits, noting the frequency, consistency, and color of your stool.
✓ Keep track of fluid intake and log any additional symptoms like nausea, vomiting, or fever.

Questions a doctor may ask you

During a clinical examination, a doctor or healthcare provider will ask detailed questions to narrow down the possible causes. Being prepared for these questions helps ensure a productive consultation:

? Where exactly is the pain located and does it travel to your back or chest?
? Is the pain constant, or does it come and go in waves or cramps?
? Do you have a fever, persistent vomiting, diarrhea, or noticed any blood in your stool?

Frequently asked questions about stomach pain

Pain localized in the lower right abdomen is a classic sign of appendicitis (inflammation of the appendix). This is a medical emergency that requires prompt evaluation, as a ruptured appendix can cause serious abdominal infections.

Yes. The gut and brain are closely connected through the nervous system (the gut-brain axis). Stress, anxiety, or emotional distress can alter gut motility, increase sensitivity to gas, and cause stomach cramping, nausea, or changes in bowel habits.

Stomach pain is likely serious if it is sudden and severe, makes the abdomen hard or tender to the touch, is accompanied by high fever, persistent vomiting, inability to pass stool or gas, or if you notice blood in your vomit or stool.
