15 Reasons You Wake Up with Stomach Pain

Common Causes of Morning Stomach Pain

1. Indigestion

Waking up with stomach pain is often due to indigestion (also called dyspepsia), which can result from eating too much, too late, or eating irritating foods. During the night, stomach acid may build up and cause discomfort in the morning.

• Burning or fullness in the upper abdomen
• Bloating or gas
• Mild nausea

• Fatty or spicy food before bed
• Late-night snacking
• Alcohol or caffeine

2. Irritable Bowel Syndrome (IBS)

 IBS is a functional bowel disorder that can cause cramping and abdominal discomfort, especially in the morning when bowel movements tend to be more active. Morning stress or anxiety can trigger symptoms.

• Cramping or bloating
• Diarrhea or constipation (or both)
• Mucus in stool

• Stress or anxiety
• Poor sleep
• Certain foods (e.g., dairy, beans and refried beans)

By the way, if you’re not sure whether your symptoms point to IBS, try using an IBS symptom checker to get a clearer idea of what might be going on.

3. Inflammatory Bowel Disease (IBD)

IBD, which includes Crohn’s disease and ulcerative colitis, causes inflammation in the digestive tract. While less common than IBS, IBD is more serious and can flare up in the early morning.

• Chronic diarrhea
• Blood in stool
• Weight loss or fatigue

Possible triggers

• Immune response or infection
• Stress or food triggers
• Genetic predisposition

4. Gastritis

Gastritis is the inflammation of the stomach lining, which may be caused by infections (like H. pylori), alcohol, or medications such as NSAIDs. It can worsen when the stomach is empty, like in the morning.

• Burning pain in the upper stomach
• Nausea or vomiting
• Loss of appetite

Possible triggers

• Spicy or acidic foods (tomatoes, citrus)
• Coffee or strong tea
• Alcohol
• Skipping meals or fasting
• Stress

5. Acid Reflux or GERD

GERD is a condition where stomach acid flows back into the esophagus, especially when lying down. It can lead to morning chest or stomach pain.

• Burning sensation in chest or stomach
• Sour taste in mouth
• Hoarseness or cough in the morning

• Late meals
• Obesity or pregnancy
• Spicy, acidic foods

6. Ulcers

Peptic ulcers are open sores in the stomach or duodenum lining (the inner surface of the first part of the small intestine). Pain is often worse on an empty stomach, such as early morning.

• Gnawing or burning pain
• Nausea
• Pain improves with food (duodenal) or worsens (gastric)

• H. pylori infection
• NSAIDs
• Smoking or alcohol

7. Gallstones

Gallstones are hardened deposits of digestive fluid (mainly cholesterol or bilirubin) that form in the gallbladder. They can block bile ducts, especially after fasting overnight, causing sharp pain in the upper right abdomen.

• Sudden pain in right upper belly or back
• Nausea or vomiting
• Pain after eating fatty meals

• Fatty meals
• Fasting
• Rapid weight loss

8. Pancreatitis

Pancreatitis is inflammation of the pancreas that can cause severe upper abdominal pain, especially after eating or lying down. It requires immediate medical attention.

• Severe, constant upper belly pain
• Nausea or vomiting
• Pain radiates to the back

• Alcohol
• Gallstones
• High triglycerides

9. Anxiety & Stress

Stress and anxiety can trigger gut-brain axis responses, leading to early morning abdominal discomfort or nausea.

• Cramping
• Bloating
• Nausea or loss of appetite

• Morning cortisol spike
• Sleep disturbances
• Upcoming stressful events

10. Constipation

When stool builds up, it can cause pain, especially upon waking when the urge to go is stronger. A sluggish digestive system from diet or inactivity may contribute.

• Cramping
• Hard, infrequent stools
• Feeling of incomplete evacuation

• Low fiber diet
• Dehydration
• Lack of exercise

11. Dehydration

Low fluid intake, especially overnight, can lead to concentrated stomach acid or muscle cramps.

• Cramping
• Dry mouth
• Dizziness or headache

• Hot weather
• Alcohol
• Low fluid intake

12. Certain Medications

Medications like NSAIDs or antibiotics can irritate the stomach lining or slow digestion.

• Bloating or discomfort
• Nausea
• Diarrhea or constipation

• Taking meds on an empty stomach
• Long-term NSAID use
• Iron supplements

13. Food Intolerances

Intolerance to lactose, gluten, or FODMAPs may cause pain after digestion starts in the morning.

• Gas or bloating
• Diarrhea
• Stomach pain

• Milk or bread products
• High-FODMAP foods
• Sugar alcohols (e.g., sorbitol)

14. Pregnancy

Hormonal changes, uterine expansion, or reflux can cause morning pain or nausea in pregnancy.

• Cramping
• Morning sickness
• Reflux

• Early pregnancy hormone changes
• Crowded digestive tract
• Delayed stomach emptying

15. More Serious Conditions (e.g., Appendicitis, Heart Attack)

Appendicitis can start with vague pain near the belly button before moving to the right lower quadrant. A heart attack can sometimes cause upper abdominal pain.

• Sharp, sudden, or worsening abdominal pain
• Pain moving to the lower right abdomen (appendicitis)
• Pressure, squeezing, or burning discomfort in the chest or upper abdomen (heart attack)
• Pain radiating to the back, jaw, neck, or left arm
• Shortness of breath, dizziness, or sweating
• Nausea, vomiting, or fever

Important: If you have sudden, severe pain or these symptoms, seek emergency medical care immediately. Act quickly to save your life.

• Infection (appendicitis)
• Cardiac risk factors (heart attack)
• Blockages or ruptures

How to Relieve Mild Morning Stomach Pain

• Eat a small, non-acidic snack before bed
• Avoid caffeine or alcohol late at night
• Try herbal teas (e.g., ginger, chamomile) in the morning
• Elevate your head while sleeping (for reflux)
• Track symptoms, meals, and stressors in a journal

Foods That Can Help or Trigger Morning Stomach Pain

What you eat the night before or even first thing in the morning, can make a big difference in how your stomach feels when you wake up. Some foods are gentle and calming, while others can stir up discomfort.

Helpful foods to try:

• Bananas - Gentle and easy to digest, plus they help restore potassium.
• Oatmeal - Warm, filling, and kind to a sensitive stomach.
• Ginger or chamomile tea - These natural soothers can calm inflammation.
• Plain yogurt - May aid digestion, especially if it contains probiotics (avoid if you’re lactose intolerant).
• Whole grain toast - Simple, light, and won’t irritate your stomach lining.

Foods that might make things worse:

• Coffee or energy drinks - Caffeine can irritate your stomach.
• Spicy meals - These can trigger reflux or discomfort.
• Fried or greasy food - Hard to digest and likely to cause heaviness or pain.
• Citrus fruits - Oranges, grapefruits, and lemon water are acidic and can worsen symptoms.

• Alcohol - Especially if consumed before bed, it irritates the stomach and can disrupt sleep.

When to See a Doctor

Morning stomach aches are usually harmless, but sometimes they’re your body’s way of asking for help. Watch out for symptoms that don’t go away or feel more intense.

You should talk to a doctor if:

• The pain is sudden, sharp, or wakes you up at night
• You’re vomiting, running a fever, or feel weak
• You notice black or bloody stool
• You can’t eat, go to the bathroom, or get relief
• The pain keeps coming back every morning, even after trying home remedies

Even if it turns out to be something mild, getting checked early helps avoid more serious problems later on.
