1. Early Stage: At this stage, the patient may start to experience mild abdominal pain, nausea, vomiting, and anorexia. Other symptoms may include low-grade fever, fatigue, and constipation. This stage may last for several days or weeks until the condition progresses.
2. Perforation Stage: This is the most serious stage, as the appendix can rupture, causing bacteria to enter the abdominal cavity. At this stage, the patient may experience a sudden and severe pain as well as a high fever. The patient may also experience chills, nausea, vomiting, and abdominal swelling.
3. Sepsis Stage: This stage occurs when the bacteria from the ruptured appendix enters the bloodstream and causes an infection. At this stage, the patient may experience a severe fever, rapid heart rate, confusion, and low blood pressure.
4. Abscess Stage: In this stage, the infection may cause a pocket of pus to form in the abdomen. The patient may experience pain in the area of the abscess as well as fever, chills, nausea, vomiting, and loss of appetite.
5. Recovery Stage: After treatment, the patient may experience a complete recovery and return to normal activities. However, the patient may also experience some persisting symptoms such as abdominal pain, nausea, and vomiting. It is important to follow up with a doctor to ensure that the infection has been completely cleared.
