A rigid, board-like abdomen along with vomiting are classic signs of peritonitis, which is a serious inflammation of the lining of the abdominal cavity. It’s often caused by infection due to a ruptured organ, like a perforated ulcer or appendix. These symptoms are medical emergencies and require immediate attention, as they can rapidly lead to life-threatening complications like sepsis.
The term “rigid board-like abdomen” refers to involuntary guarding—where the abdominal muscles contract so tightly that the abdomen feels hard—often indicating acute abdominal distress.
⚠️ If someone is experiencing these symptoms, seek emergency medical care immediately. Do not wait.
