Upset stomach or abdominal pain and chills can result from bacterial and viral conditions, such as food poisoning or gastroenteritis. It may also occur with serious conditions, such as a kidney infection or appendicitis.

Abdominal pain is pain that originates between the chest and the pelvis. It can be cramp-like, achy, dull, or sharp and is often called stomachache.

Chills cause you to shake or shiver as if you’re very cold. Shivering is one way the body protects itself from cold. It causes the muscles to flex and extend to warm them up. You may feel cold when you have the chills, or you may shiver without feeling cold. Chills are often associated with fevers.

In an emergency

If your symptoms feel severe or are accompanied by other severe symptoms, such as chest pain, high fever, or changes in vision or consciousness, you may need emergency medical attention. Visit an emergency room or contact 911 or your local emergency services.

Treatments for abdominal pain and chills will usually address the underlying causes. Doctors treat bacterial infections, such as urinary tract infections or kidney infections, with antibiotics.

Certain causes, such as appendicitis or gallstones, may be treated with surgery.

A doctor may recommend home care if the cause is a viral infection like infectious mononucleosis or viral gastroenteritis.

Home care

Rest and drink plenty of fluids to prevent dehydration. Sponge your body with lukewarm water about 70˚F (21˚C), or take a cool shower to manage your chills. This method can be more effective than covering yourself with blankets. However, very cold water may make chills worse.

Over-the-counter medications may help reduce fever and discomfort associated with abdominal pain and chills. These may include:

  • aspirin (Bayer)
  • acetaminophen (Tylenol)
  • naproxen (Aleve)
  • ibuprofen (Advil)

Aspirin should not be given to infants, children, or teens. In children, it can potentially cause Reye’s Syndrome, a rare condition that can lead to brain and liver damage.

Washing your hands frequently, especially before eating, can help prevent viral and bacterial infections that may lead to abdominal pain and chills.

Drinking plenty of fluids and wiping from front to back can help prevent urinary tract infections that can lead to abdominal pain and chills. Drinking a glass of water before sex and urinating afterward can help rinse out the bladder.

If you are going outdoors or traveling to areas where malaria is common, using insect repellants that contain 20 to 35 percent DEET can help to prevent malaria. A doctor can prescribe anti-malarial drugs as a protective means if you travel to an area where malaria is common. These medications are preventive and need to be started before traveling.

Many conditions may cause abdominal pain and chills. These may include viral or bacterial infections, blockages, and injury.

Depending on the cause and severity, you may treat abdominal pain and chills at home.

But if the pain is severe or occurs with other severe or concerning symptoms, you may need urgent medical care.
