Common Causes of Stomach Pain

Most cases of stomach pain are not life-threatening. Here are some of the most frequent reasons your gut may be hurting:

1. Indigestion (Dyspepsia)

Often triggered by:

• Overeating
• Eating too quickly
• Spicy or fatty foods
• Alcohol
• Stress

You may feel burning, bloating, nausea, or discomfort in the upper abdomen.

2. Gas and Bloating

Gas buildup in the intestines can cause:

• Cramping
• Pressure
• Sharp pains that move around
• Relief after passing gas

This is common and usually harmless.

3. Constipation

When stool moves too slowly through the intestines, it can cause:

• Lower abdominal discomfort
• Bloating
• Straining
• Hard or infrequent bowel movements

4. Stomach Flu (Gastroenteritis)

Often caused by viruses, symptoms may include:

• Cramping
• Diarrhea
• Nausea or vomiting
• Mild fever

Most cases improve within a few days with hydration and rest.

5. Acid Reflux (GERD)

Stomach acid backing up into the esophagus can cause:

• Burning pain in the upper abdomen or chest
• Sour taste in the mouth
• Symptoms after meals or when lying down

6. Irritable Bowel Syndrome (IBS)

A common digestive disorder that may cause:

• Recurrent stomach pain
• Diarrhea, constipation, or both
• Bloating
• Symptoms that improve after a bowel movement

IBS is chronic but manageable with lifestyle and dietary adjustments.

What You Can Do Right Now

If your stomach pain is mild and you have no emergency symptoms, you can try these medically recommended steps:

✅ Rest Your Gut

• Avoid large or heavy meals
• Choose bland foods (rice, toast, bananas, broth)
• Eat small portions

✅ Stay Hydrated

• Drink water regularly
• If you have diarrhea or vomiting, use oral rehydration solutions

✅ Adjust Your Diet

Consider reducing:

• Fatty foods
• Spicy foods
• Alcohol
• Carbonated drinks

For some people, limiting dairy or high-FODMAP foods may help.

✅ Manage Stress

The gut and brain are closely connected. Stress can worsen stomach pain. Try:

• Gentle movement
• Deep breathing
• Adequate sleep

✅ Over-the-Counter Options (If Appropriate)

• Antacids for acid-related pain
• Fiber supplements for constipation
• Simethicone for gas

If symptoms persist, don't rely on self-treatment alone.

Special Considerations

In Children

Stomach pain is common and often mild, but seek care if:

• The child is lethargic
• Pain is severe or localized
• There is persistent vomiting or fever

During Pregnancy

Any new or severe stomach pain should be discussed with a healthcare provider.

In Older Adults

Abdominal pain may present less clearly but carry greater risk. Early evaluation is wise.
