there are many reasons you might have abdominal pain and a headache at the same time. While many of these causes are not serious, some may be. These pains can potentially be signs of a larger problem.
Both abdominal and headache pain can range from mild to severe pain, depending on the cause. Read on to learn more about potential causes and treatments.
Abdominal pain and headache causes
Some causes of concurrent abdominal pain and headaches are common, while others are rarer. Some may be mild, while others are serious. Below are some of the potential causes of abdominal pain and headache, from most to least common.
The common cold is a viral infection of the nose and throat. Most people get a few colds per year, and recover in 7 to 10 days without treatment. However, you can treat the individual symptoms of a common cold. Other symptoms include:
stuffy or runny nose
general feeling of being unwell
Gastroenteritis may sometimes be called the stomach flu, but it’s not actually the flu. It’s an inflammation of the lining of your intestines, caused by a virus, bacteria, or parasites. Viral gastroenteritis is the second most common illness in the United States. Other symptoms include:
A food intolerance, or sensitivity, is when you have difficulty digesting a certain type of food. It is not an allergy. Lactose intolerance is a common food intolerance. Other symptoms include:
Salmonella is a foodborne illness, usually spread through meat, poultry, eggs, or milk. It is one cause of bacterial gastroenteritis. Other symptoms include:
Urinary tract infection (UTI)
A urinary tract infection is an infection in any part of the urinary system. It most commonly occurs in the bladder or urethra. UTIs are more common in women. They don’t always cause symptoms, but when they do, those symptoms include:
strong, persistent urge to urinate
pain while urinating
red, pink, or brown urine
urine that smells bad
pelvic pain (especially in women)
Urine carries waste in it. When there’s too much waste in your urine, it can form crystals and create a solid mass called a kidney stone. These stones can get stuck in your kidney or urethra.
In many cases, the stones pass naturally, but they can also back up urine and cause a lot of pain. Symptoms of kidney stones include:
severe pain on one side of your lower back
blood in your urine
urine that smells bad
Prostatitis is an inflammation of the prostate. It can be caused by bacteria, but often the cause is unknown. Prostatitis may not cause any symptoms, but if it does, those symptoms include:
pain that lasts for at least 3 months in at least one of the following areas: between your scrotum and anus, lower abdomen, penis, scrotum, or lower back
pain during or after urination
urinating eight or more times a day
not being able to hold urine when necessary
weak urine stream
inability to completely empty your bladder
urinary tract infections
Mononucleosis (mono) is a contagious disease that is most common in teens and young adults. Symptoms usually last 4 to 6 weeks, but can last longer. Symptoms include:
swollen lymph nodes
Abdominal migraine is a form of migraine most common in children. Most children with this condition grow out of it and develop more typical migraine headaches instead. Attacks usually last 2 to 72 hours, and may include:
moderate to severe pain around the belly button
loss of appetite
Gastrointestinal diseases include a wide range of diseases that fall into two categories: functional and structural. Functional gastrointestinal diseases are when the gastrointestinal (GI) tract looks normal but doesn’t function properly. These include constipation and irritable bowel syndrome.
Structural gastrointestinal diseases are when the bowel doesn’t look or functional normally. Examples include hemorrhoids, colon cancer, polyps, and inflammatory bowel diseases like ulcerative colitis and Crohn’s disease.
The flu is a respiratory illness caused by influenza virus. It can be mild to severe, and can even lead to death. Fatal cases are more common in the very young, the elderly, or people who are immunocompromised. Symptoms usually come on suddenly and include:
runny or stuffy nose
vomiting and diarrhea (less common symptoms)
Pneumonia is an infection in the air sacs of one or both lungs. It can range from mild to life-threatening. Other symptoms include:
cough with phlegm
Gallbladder inflammation usually occurs when a gallstone blocks the cystic duct, which carries bile out of the gallbladder. This inflammation is also called cholecystitis and can be acute (come on suddenly) or chronic (long-term). Gallbladder inflammation requires hospitalization and may require surgery. Other symptoms include:
severe and steady abdominal pain in acute cholecystitis
abdominal pain that comes and goes in chronic cholecystitis
Pelvic inflammatory disease
Pelvic inflammatory disease is an infection in a women’s reproductive organs. It’s caused by bacteria, usually from a sexually transmitted infection, and can cause fertility issues if not treated. Pelvic inflammatory disease often does not cause symptoms, but potential symptoms include:
lower abdomen pain
foul-smelling vaginal discharge
pain during sex
pain while urinating
irregular menstruation, such as very long or short cycles
Appendicitis is a blockage in your appendix. It can cause pressure to build up in the appendix, problems with blood flow, inflammation, and potentially cause the appendix to rupture.
Appendicitis is a medical emergency. If you think you may have appendicitis, go to the hospital as soon as possible. Symptoms include:
sudden abdominal pain, usually on the right side
loss of appetite
constipation or diarrhea
inability to pass gas
Diverticulosis is when small pouches, or sacs, form in your colon and push outward through weak spots in your colon walls. When the sacs become inflamed, you have developed diverticulitis. Diverticulosis often does not cause symptoms, but diverticulitis have potential symptoms that include:
pain in your lower left abdomen
constipation or diarrhea
Other, rarer causes of concurrent abdominal pain and headache include:
cyclical vomiting syndrome, which causes recurrent episodes of severe nausea and vomiting
hyperimmunoglobulin D syndrome, a rare genetic disorder that causes high fever, headaches, abdominal pain, and loss of appetite
postural orthostatic tachycardia syndrome (POTS), a condition that affects circulation (symptoms include lightheadedness, fainting, and an increased heartbeat after standing up from reclining position)
Abdominal pain and headache after eating or drinking
If your symptoms develop 8 to 72 hours after eating or drinking, abdominal pain and a headache may be due to gastroenteritis. If the pain comes on sooner, it may be due to a food intolerance or gastrointestinal disease.
Abdominal pain and headache during pregnancy
The most common cause of abdominal pain and a headache during pregnancy is a urinary tract infection.
Abdominal pain and headache with nausea
The most common cause of abdominal pain and a headache with nausea is gastroenteritis (stomach flu).
