8 Possible Stomach Bloating Causes

The list below shows results from the use of our quiz by Buoy users who experienced stomach bloating. This list does not constitute medical advice and may not accurately represent what you have.

Indigestion (dyspepsia)

Indigestion, also called upset stomach, dyspepsia, or functional dyspepsia, is not a disease but a collection of very common symptoms. Note: Heartburn is a separate condition.

Common causes are eating too much or too rapidly; greasy or spicy foods; overdoing caffeine, alcohol, or carbonated beverages; smoking; and anxiety. Some antibiotics, pain relievers, and vitamin/mineral supplements can cause indigestion.

The most common symptoms are pain, discomfort, and bloating in the upper abdomen soon after eating.

Indigestion that lasts longer than two weeks, and does not respond to simple treatment, may indicate a more serious condition. Upper abdominal pain that radiates to the jaw, neck, or arm is a medical emergency.

Diagnosis is made through patient history and physical examination. If the symptoms began suddenly, laboratory tests on blood, breath, and stool may be ordered. Upper endoscopy or abdominal x-ray may be done.

For functional dyspepsia – "ordinary" indigestion – treatment and prevention are the same. Eating five or six smaller meals per day with lighter, simpler food; managing stress; and finding alternatives for some medications will provide relief.

Normal variation of constipation

Constipation means bowel movements which have become infrequent and/or hardened and difficult to pass.

There is wide variation in what is thought "normal" when it comes to frequency of bowel movements. Anywhere from three times a day to three times a week is considered normal.

As long as stools are easy to pass, laxatives should not be used in an effort to force the body to a more frequent schedule.

Constipation is usually caused by lack of fiber in the diet; not drinking enough water; insufficient exercise; and often suppressing the urge to have a bowel movement.

A number of medications and remedies, especially narcotic pain relievers, can cause constipation.

Women are often affected, due to pregnancy and other hormonal changes. Young children who demand low-fiber or "junk food" diets are also susceptible.

Constipation is a condition, not a disease, and most of the time is easily corrected. If simple adjustments in diet, exercise, and bowel habits don't help, a doctor can be consulted to rule out a more serious cause.

FAQs About Stomach Bloating

Here are some frequently asked questions about stomach bloating.

Why do I have a bloated stomach after eating?

You may have abdominal bloating after eating if you have consumed a particularly gas-inducing foods. These include meats and cheeses and anything more difficult to digest that will leave a significant amount for bacteria in the gut to digest. Beans may also produce bloating as they contain compounds that are much easier for bacteria in the gut to digest and produce H2 gas from.

What foods are good to reduce stomach bloating?

Insoluble fibers like rice, carrots, certain types of beans and legumes, tomatoes, and live cultures like yogurt and kefir can reduce gas by slowing down digestion, helping establish a more preferential balance of bacteria in the gut and diluting out gas-causing compounds.

Why does my stomach bloat before my period?

Bloating of the stomach or abdomen is often attributed to both the swelling of the uterus before menstruation as well as the retention of fluids during the premenstrual phase due to changes in the relative amounts of progesterone and estrogen. Usually the excess water that builds up dissipates during the term of the menses.

Why does my stomach bloat without eating?

Bloating can occur without eating for individuals that drink substances that increase bloating like alcohol, carbonated beverages, or sugary beverages. It can also be significantly increased in individuals with slow small gut motility (the speed at which substances travel through the small intestine).
