Common causes include indigestion, gastritis, and irritable bowel syndrome (IBS). These conditions can result from factors like diet, stress, or infections. Symptoms of stomach issues may vary but often include nausea, cramping, and changes in appetite. Treatment typically involves dietary adjustments, medications, or lifestyle changes. If symptoms persist, it is important to consult a healthcare professional for proper diagnosis and management.
