Abdominal pain that develops or worsens may suggest appendicitis, but no single symptom is sufficient to confirm the diagnosis. The location of the pain, digestive symptoms, and overall condition vary from person to person. A medical evaluation is therefore necessary when the clinical picture is suggestive, especially if the pain becomes severe, spreads, or is accompanied by general malaise.
This guide explains possible symptoms, the role of examination and imaging, and the main treatment options. It is not intended for self-diagnosis and should not delay contact with a healthcare professional.
What symptoms might suggest appendicitis?
Pain is the most common symptom. It may start around the navel and then move down and to the right side of the abdomen. In other people, it appears directly in this area or remains less localized. It often tends to become continuous and may be aggravated by movement, coughing, or palpation.
- loss of appetite or feeling of food aversion;
- nausea, sometimes accompanied by vomiting;
- fever or feverish sensation;
- constipation, diarrhea or unusual changes in bowel movements;
- pain that limits movement or forces one to remain immobile.
The absence of fever or vomiting does not rule out appendicitis. Conversely, these symptoms are present in many other digestive, urinary, or gynecological diseases. The combination of signs and their progression are more important than any single symptom.
A different presentation depending on age and situation
The appendix is not located in exactly the same position in everyone. Therefore, pain higher up, more centrally, in the pelvis or lower back is still possible. In children, the elderly, pregnant women, or immunocompromised individuals, the signs may be less typical and the examination more difficult to interpret.
In a woman who may be pregnant, abdominal or pelvic pain also requires prompt investigation to rule out other emergencies. In children, a change in behavior, refusal to eat, unusual drowsiness, or persistent pain warrants medical attention. In the elderly, a decline in their overall health may be more noticeable than the pain itself.
How is the diagnosis made?
The diagnosis begins with an interview and a clinical examination. The doctor notes the time of onset, location, and progression of the pain, looks for associated symptoms, and takes into account the patient's medical history, current treatments, and any pregnancy. Palpation of the abdomen helps to identify a painful area or signs of peritoneal irritation.
Analysis and Imaging
Blood and urine tests can look for inflammation, a urinary tract infection, or another diagnosis. Their results alone do not confirm appendicitis. Ultrasound, CT scans, or MRIs are chosen based on the patient's age, clinical situation, possible pregnancy, and initial findings. Sometimes, monitoring and further testing are preferable to an immediate decision when the diagnosis remains uncertain.
The French National Health Insurance (Assurance Maladie) reminds us that several conditions can resemble appendicitis: digestive or urinary tract infections, inflammatory bowel disease, ovarian problems, ectopic pregnancy, or testicular torsion. This diversity explains why self-diagnosis is unreliable.
Simple or complicated appendicitis: why the distinction matters
Imaging and examination are used, in particular, to look for perforation, abscess, extensive inflammation, or appendicitis. These factors influence the treatment decision and the level of monitoring. Uncomplicated appendicitis is not necessarily treated in the same way as a form accompanied by an abscess or peritonitis.
International guidelines emphasize the importance of tailored care based on the patient's profile and available resources. Therefore, the term "appendicitis" does not refer to a uniform condition and cannot be used to determine the appropriate treatment on its own.
What treatments can be offered?
Appendectomy
An appendectomy is the removal of the appendix. Laparoscopy is frequently used, but another approach may be chosen depending on the patient's condition, the extent of the infection, the anatomy, and the surgical conditions. The surgeon and anesthesiologist explain the procedure, the expected benefits, the risks, and the alternatives applicable to the situation.
The timing of the intervention depends on the complexity of the appendicitis and the team's assessment. Prompt consultation remains necessary, but this does not mean that every patient must be operated on within the same timeframe.
Non-operative treatment
In certain carefully selected cases of uncomplicated appendicitis, antibiotic treatment may be considered. This requires a documented diagnosis, information about the risk of treatment failure or recurrence, and organized monitoring. It is neither self-medication nor a suitable alternative for everyone.
The choice of medications, their route of administration, and their duration are determined solely by the medical team. In the presence of an abscess or other complication, surgery, antibiotic therapy, and drainage may play different roles depending on the clinical presentation.

After an appendectomy
The length of hospital stay and the pace of recovery vary depending on the surgical technique, the presence of complications, the patient's overall condition, and the facility's guidelines. Before discharge, the team will specify wound care, prescribed treatments, dietary requirements, permitted activities, and follow-up care.
- Follow only the prescription and instructions given;
- Do not resume physical activity based on a schedule found online;
- report any increasing pain, persistent vomiting, or any worrying change in the wound;
- Ask how to contact the service if you have any doubts.
Our guide to post-surgery recovery at home helps organize documents and contacts without replacing your surgeon's instructions. Returning to work should also be tailored to each individual; our guide to taking time off work after surgery outlines the general steps.
When should you seek emergency care?
Severe, persistent, or rapidly increasing abdominal pain requires evaluation, especially if accompanied by repeated vomiting, fever, abdominal rigidity, malaise, or a general decline in health. Following surgery, recurrence of pain, bleeding, wound drainage, difficulty breathing, or chest pain should also be reported immediately.
In case of distress, loss of consciousness, very intense pain or other obvious emergency, call 15 or 112.
F.A.Q
Is it possible to have appendicitis without a fever?
Yes. Fever may be absent, particularly at the beginning or in some atypical presentations. Persistent or progressive pain should be evaluated even without fever.
Does a normal ultrasound rule out the diagnosis?
Not always. The appendix can be difficult to visualize. The doctor interprets the imaging in conjunction with the symptoms, examination, and tests, then decides whether monitoring or further testing is necessary.
Should I take an antibiotic before consulting a doctor?
No. Inappropriate antibiotic therapy can modify the symptoms without properly treating the cause. Treatment should be decided after a medical evaluation.
