Appendicitis is caused due to the inflammation of the appendix. The appendix gets inflamed when it is clogged with mucus, fecal matter, parasites, or bacteria. Although the appendix does not perform any important function in the body, its presence in the gastrointestinal tract is considered essential for the health of the immune system. Some experts consider the appendix important to fend off infections. When the appendix gets blocked and there is no immediate treatment, there might be an appendix rupture followed by an infection. The infection due to a burst appendix may lead to a life-threatening condition. This makes it essential to diagnose appendicitis as soon as possible. An identification of early appendicitis symptoms can be useful for a timely diagnosis. Here are a few early appendicitis symptoms: Mild abdomen pain : This is one of the most common early appendicitis symptoms. There will be a dull ache in the lower right area of the abdomen. The pain will usually start from the belly button. The dull ache turns into severe pain within a couple of hours. The pain is debilitating and intensifies pretty quickly. Painful body movement : As the appendicitis pain becomes severe, it will become difficult to perform daily activities.
