Top 6 Causes of Stomach Cramps

1. Indigestion

Also known as dyspepsia, indigestion is a feeling of pain or discomfort in the upper part of the abdomen. Common symptoms of indigestion include bloating, belching, a noisy stomach, nausea, a burning sensation in the stomach, and stomach cramps.[1] Stress and anxiety can worsen symptoms.

Indigestion can indicate the presence of medical conditions such as gallbladder disease, chronic pancreatitis, and thyroid disease. Certain medications, such as antibiotics and oral contraceptives, can trigger indigestion, as can unhealthy lifestyle habits, which might include cigarette smoking and alcohol abuse.[2] Indigestion can be prevented by eating more slowly, reducing caffeine intake, and quitting smoking.

2. Constipation

Constipation occurs when bowel movements become infrequent or are difficult to pass because of hard, dry feces. With constipation, bowel movements occur no more than three times per week.[3] Constipation tends to cause pain and general discomfort, and it is further characterized by symptoms that include nausea, bloating, loss of appetite, stomach cramps, and straining during bowel movements.

Constipation can be caused by a number of different factors, such as lack of fiber in the diet, dehydration, low physical activity, and medications that include opioids and antidepressants.[3] Diseases and medical conditions such as diabetes, multiple sclerosis, and cancer can also cause constipation. People with this condition can find relief by exercising regularly, drinking more water, and consuming more high-fiber foods. In severe cases, laxatives and other medications can reduce symptoms.

3. Menstrual Cramps

Women with menstrual cramps experience dull, throbbing pain in their lower abdomen before and during a menstrual period. When a woman’s egg doesn’t become fertilized, hormones called prostaglandins cause the uterus to contract so it can expel its lining during menstruation.[4] Stomach cramps experienced before and during the menstrual period can sometimes be comparable to mild labor pains.

Common symptoms that accompany menstrual cramps include headache, dizziness, nausea, and loose stools. Women at highest risk for menstrual cramps are those who smoke, bleed heavily during periods, bleed at irregular intervals, or have a family history of menstrual cramps. In some instances, menstrual cramps can be triggered by more serious conditions, including uterine fibroids, pelvic inflammatory disease, or endometriosis.[4]

4. Lactose Intolerance

People with lactose intolerance cannot fully digest a milk sugar called lactose. With lactose intolerance, the small intestine produces low amounts of an enzyme called lactase that breaks down lactose during digestion. A person who is lactose intolerant experiences extreme discomfort and other symptoms after eating milk and dairy — including bloating, gas, and diarrhea. Nausea, vomiting, and stomach cramps are other common symptoms of lactose intolerance.[5]

Lactose intolerance can be caused by genetics or by injury to the small intestine such as that caused by Crohn’s disease and celiac disease. Radiation therapy and certain medications can also contribute to this digestive condition. Those who suffer from lactose intolerance can prevent symptoms by avoiding foods and drinks that contain lactose or by working with a doctor who can treat underlying medical conditions.[6]

5. Food Allergies

When someone has a food allergy, their immune system responds abnormally to a certain food and produces a set of symptoms — some of which can be life-threatening. Many foods can trigger allergic reactions, but the foods most commonly associated with allergies are fish, peanuts, eggs, milk, soy, and wheat.[7] Symptoms of food allergies include hives, rasheczema, swelling in the mouth, vomiting, diarrhea, stomach cramps, and difficulty breathing.

Risk factors for food allergies include having asthma or at least one other allergy and having a family history of asthma, eczema, or allergies. Allergic reactions to foods may be prevented by avoiding contact with foods you’re allergic to and informing servers at restaurants about your allergies.[7]

6. Food Poisoning

Food poisoning, also known as foodborne illness, is caused by eating foods that have been contaminated with viruses, bacteria, parasites, and dangerous toxins. Symptoms of food poisoning vary depending on the source and severity of the contamination and include nausea, vomiting, fever, painful diarrhea, and severe stomach cramps.[8] Food poisoning symptoms can last anywhere from a few hours to several days depending on the severity of the illness.

Food can become contaminated at any point between its growth and preparation. Chemicals used during the cultivation process can cause contamination, as can poor hygienic habits such as failing to wash hands before handling food. Those at highest risk for food poisoning are those with poor or weakened immune systems, such as infants, older adults, and people with chronic diseases like AIDS and diabetes.[9]
