Upset Stomach: What Causes It and How to Find Relief

When dealing with upset stomach, a painful or uncomfortable feeling in the abdomen often marked by bloating, cramping, or irregular bowel movements. Also known as indigestion, it can stem from many everyday factors. Understanding the root cause makes it easier to pick the right remedy and avoid future flare‑ups.

One of the most common companions of an upset stomach is nausea, the uneasy sensation that often precedes vomiting and signals that the digestive tract is irritated. Nausea can arise from food poisoning, motion sickness, or even stress, and it frequently triggers that queasy feeling in the gut. Another frequent driver is gastroenteritis, an inflammation of the stomach and intestines usually caused by viral or bacterial infections. When gastroenteritis strikes, the lining of the gut swells, leading to cramping, diarrhea, and that stubborn upset stomach many of us dread.

Don’t forget acid reflux, the backflow of stomach acid into the esophagus that creates burning and can irritate the stomach lining. Acid reflux often overlaps with heartburn, and the extra acid can worsen stomach discomfort. Sometimes, the culprit isn’t a disease at all but medication side effects—common drugs like NSAIDs, antibiotics, or iron supplements can irritate the stomach lining and provoke symptoms. Knowing these links—upset stomach ↔ nausea, upset stomach ↔ gastroenteritis, upset stomach ↔ acid reflux, and upset stomach ↔ medication side effects—helps you target the right fix.
