Nighttime abdominal pain, sometimes called stomach pain, can occur for various reasons. Often, it is due to gas or other digestive issues, but there may be a more severe underlying cause, such as gallstones.
Here, learn about some common causes of nighttime abdominal pain and how to manage or treat it.
Digestive problems are considered the most common cause of abdominal pain at night.
Eating close to bedtime means digestion is more likely to occur while lying down, making it easier for stomach acid to travel back up the digestive tract.
Lying down can also increase pressure on some muscular, joint, or bone injuries, making pain and discomfort more intense.
Here are some common causes of nighttime abdominal pain:
Gas usually enters the body when people swallow gas, for example, when smoking, chewing gum, eating quickly, or consuming fizzy drinks. Certain bacteria in the gut also produce gas when they break down carbohydrates. Sometimes, it results from a medical condition, such as IBD or food sensitivity.
- high alcohol consumption
- overeating, especially close to bedtime
- lying down too soon after eating
- being overweight
- high-fat, spicy, and fried foods, along with chocolate and coffee
Gastroesophageal reflux disease
Gastritis is when the stomach walls become irritated and inflamed. This
Stomach and intestinal, or peptic, ulcers
Stomach ulcers and intestinal ulcers
- H. pylori bacteria
- overuse or prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs)
- tumors, in rare cases
Fatty or rich meals can worsen gallstone symptoms since bile helps the body digest fat.
Some individuals with gallstones have no symptoms and do not need medical help. People with recurring gallbladder pain or inflammation may need surgery to remove the gallbladder.
As well as pain, gallstones can also cause the following complications:
Irritable bowel syndrome
Some people with irritable bowel syndrome (IBS) experience nighttime abdominal pain.
Around 5–10% of people have IBS, and most are under 50.
An allergy to gluten, a protein in wheat, barley, rye, and spelt, causes inflammation of the small intestine, often with cramping and abdominal pain. Genetic factors probably underlie the allergy.
Without diagnosis or treatment, complications can arise. They include dental problems, delayed puberty, mood changes, and reduced growth due to vitamin and mineral deficiencies.
Experts do not know why it develops, but it may be due to an autoimmune reaction or genetic factors. Smoking may also increase the risk.
Symptoms range from mild to severe and may affect the back and legs. There may also be nausea, vomiting, headaches, and other symptoms.
With endometriosis, tissue similar to endometrial tissue grows outside the uterus. This can cause severe or persistent pain, bleeding and spotting, and digestive problems. It can make it harder to become pregnant.
Endometriosis may affect
Individuals with a food intolerance have a sensitivity to certain foods and cannot properly digest or process them. They may experience pain, bloating, diarrhea, and gas. Symptoms usually start soon after eating the food but may appear up to 48 hours later.
Lactose intolerance is a common food intolerance that causes severe abdominal cramping and pain.
Constipation makes it difficult to pass stool. As a result, waste products build up in the colon, leading to distention, pain, and pressure throughout the abdomen. Stools will be hard, dry, and difficult to pass.
Often, nighttime abdominal or stomach pain is not a reason for immediate concern. Severe or persistent symptoms, however, need medical attention.
People also should seek medical advice if they have additional symptoms, such as:
- severe or ongoing pain that does not lessen with over-the-counter medications
- difficulty breathing
- unexplained weight loss
- abdominal swelling or inflammation
- abdomen that is painful to touch
- yellowing of the skin and eyes
- ongoing nausea or vomiting, especially if vomiting blood
- blood in the stool
- pain that occurs during pregnancy
- joint and muscle aches
Sometimes, sudden severe abdominal pain can indicate a more serious condition that requires medical attention.
These conditions include:
- kidney stones
- food poisoning
- heart attack
- hiatal hernia
- stomach cancer
- other cancers in the abdominal area
In the case of any of these conditions, medical evaluation is important to receive a proper diagnosis and treatment.
