Peptic ulcers are open sores that develop in the lining of the stomach, upper small intestine, or esophagus. Recognizing the signs of peptic ulcers is crucial for early detection and timely treatment. Remember, these symptoms can vary from person to person, and some individuals may experience no symptoms at all. If you suspect you have peptic ulcers or are experiencing any of these signs, consult a doctor for further diagnosis.
