Below are the most common causes of abdominal pain, as well as the signs and symptoms of abdominal pain that requires medical attention.
The Most Common Causes of Abdominal Pain: Indigestion
Indigestion refers to a discomfort felt during or after eating, ranging from feeling full to actual pain. Indigestion can be a sign of a health problem, such as gastroesophageal reflux disease (GERD) or cancer, but is frequently due to simply eating or drinking too much. Medications that irritate the stomach, stress, fatigue, and anxiety can also lead to indigestion.
Symptoms of indigestion include abdominal pain, bloating, belching, gas, nausea, vomiting, acidic taste, and burning in the stomach or upper abdomen (not to be confused with heartburn, which is felt in the chest and throat).
The Most Common Causes of Abdominal Pain: Constipation
Whether they want to discuss it or not, most people experience constipation at some point in their life. Constipation is the inability to have a normal bowel movement. This can be in the form of having to strain to have pass stools or not being able to have a bowel movement at all.
Constipation can be brought on due to simple things, such as a change in diet or routine, or an underlying health problem. Symptoms include abdominal pain, abdominal pressure, swollen abdomen, difficult bowel movements, a lack of bowel movements, and vomiting.
The Most Common Causes of Abdominal Pain: Gastroenteritis (Stomach 'flu')
Many people call it stomach flu, but they are really referring to gastroenteritis. The pain associated with gastroenteritis is due to the irritation and inflammation of the lining of the stomach and intestines, which can be caused by a virus or bacterial infection.
Symptoms of gastroenteritis include abdominal pain, abdominal cramps, nausea, vomiting, diarrhea, swollen lymph glands, fatigue, and fever.
The Most Common Causes of Abdominal Pain: Menstrual Pains
Abdominal pain felt during menstruation is commonly due to menstrual cramps, which are caused by the contraction of the muscles of the uterus brought on by hormone changes. Menstrual cramps may range from mild annoyances to strong pains that interfere with daily activities.
For some women, the pain is severe or continues after menstruation. In these cases, there may be other health conditions involved, such as pelvic inflammatory disease, endometriosis or fibroids.
The Most Common Causes of Abdominal Pain: Food Poisoning
Food poisoning may cause mild abdominal pain or a severe life-threatening infection, depending on the type of bacteria or parasite involved. There are over 250 food and water borne illness that can cause food poisoning symptoms, including the commonly known Salmonella, E. Coli, and botulism.
Symptoms of food poisoning include abdominal pain, abdominal cramps, nausea, vomiting, diarrhea, fatigue, weakness, and fever. The severity of the symptoms will vary depending on the bacteria or parasite involved with the infection.
The Most Common Causes of Abdominal Pain: Food Allergies and Food Intolerances
A food allergy is an immune system response to a certain compound in food, usually a protein. Between 2 to 4% of adults and 6 to 8% of children have true food allergies. Food intolerance, which is much more common, is a digestive response to foods, often due to the digestive system being low in a needed enzyme or sensitivity to a chemical additive. Both food allergy and food intolerance can lead to abdominal pain.
Symptoms of a food allergy occur every time the food is consumed and include abdominal pain, nausea, diarrhea, rash, hives, shortness of breath, chest pain, and anaphylaxis.
Symptoms of food intolerance increase depending on how much of the offending food is consumed and include abdominal pain, nausea, gas, abdominal cramps, bloating, vomiting, heartburn, diarrhea, headache, and irritability.
The Most Common Causes of Abdominal Pain: Gas
Every human being produces and passes gas, though usually only men want to discuss it. Gas is naturally formed as the digestive system breaks down food. Some foods, though, are known to produce more gas than others as the body works on them. These include high fiber foods such as beans, vegetables, fruits, and whole grain products. Other foods that can increase gas in the body include dairy products, soft drinks and fruit juices. An excess of gas in the system can lead to bloating and abdominal pain.
Frequent painful gas (belching or flatulence) can be a sign of health problems, such as ulcers, gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS), and colon cancer.
The Most Common Causes of Abdominal Pain: Lactose Intolerance
Lactose intolerance is the inability to digest lactose (the sugar found in dairy products) due to the body not making enough of the enzyme lactase. The abdominal pain and other symptoms of lactose intolerance generally start anywhere from 30 minutes to two hours after consuming dairy products.
Symptoms of lactose intolerance include abdominal pain, abdominal cramping, nausea, painful gas, bloating and diarrhea.
