Stomach pain is a common complaint, but when is it something serious like appendicitis? Many people brush off abdominal discomfort as indigestion or gas. Still, if it’s persistent, sharp, and located in the lower right side, it could be a sign of a medical emergency.
This blog will help you understand the warning signs of appendicitis, what causes it, and when you should see a doctor—before it’s too late.
What Is Appendicitis?
Appendicitis is the inflammation of the appendix, a small, finger-shaped pouch attached to the large intestine. Though its function is unclear, when the appendix becomes inflamed, it can cause intense abdominal pain that requires surgery in most cases.
According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), appendicitis is one of the most common causes of emergency abdominal surgery.
Warning Signs of Appendicitis
- Sudden Pain Around the Belly Button:
Pain often starts around the navel area and then shifts to the lower right side of the abdomen.

- Worsening Pain with Movement:
Walking, coughing, or pressing on the lower right side of your abdomen may intensify the pain.
- Loss of Appetite:
Many people with appendicitis report suddenly losing their desire to eat, which is a red flag.
- Nausea and Vomiting:
These symptoms often follow the onset of abdominal pain and are common in many cases.

- Low-Grade Fever:
A mild fever (99–100.5°F) may occur and worsen as the infection progresses.
- Constipation or Diarrhea:
Changes in bowel habits, especially when accompanied by abdominal pain, may point to an inflamed appendix.
- Abdominal Swelling:
In later stages, the abdomen may become bloated and tender to the touch.

What Causes Appendicitis?
Appendicitis occurs when the appendix becomes blocked, often by:
- Hardened stool (fecalith)
- A gastrointestinal infection
- Enlarged lymphoid tissue
- Foreign bodies or tumors (rare)
Once blocked, bacteria inside the appendix multiply, causing it to swell and become infected. If left untreated, it can burst (rupture), leading to serious complications like peritonitis or sepsis.
When to Seek Medical Help
If you notice a combination of symptoms—especially sharp, localized pain on the lower right side of your abdomen—it’s crucial to seek medical attention immediately. Do not ignore these warning signs or attempt to self-medicate, as a ruptured appendix can quickly become a life-threatening emergency. Urgent care is also essential if you are pregnant and experiencing unusual abdominal pain, if a high fever accompanies your symptoms, or if you are unable to pass gas and are vomiting persistently. Prompt diagnosis and treatment can prevent serious complications and save your life.
Final Thoughts
Appendicitis isn’t just “a stomach ache.” It’s a condition that demands swift action. If you or a loved one shows the signs mentioned above, don’t wait—early diagnosis can save your life.
When it comes to abdominal pain, it’s always better to be safe than sorry.
