Pain in the lower right side of your stomach might be due to common problems like appendicitis or other conditions affecting your intestines or colon. Other causes could include, gas, constipation, right-sided diverticulitis, ovarian cyst rupture or torsion.
Pain in the lower right part of the stomach can be linked with appendicitis, which is when your appendix gets swollen and infected. However, there are other conditions that can also cause pain in this area. For example, right-sided colonic diverticulitis occurs when small pouches in the large intestine become inflamed. There may be other gastrointestinal causes, such as inflammation of the small bowel (ileitis) or even conditions like Crohn’s disease that affect the intestines. Some infections can also lead to discomfort in this region. Doctors usually use imaging tests like CT scans and blood work to understand exactly what is happening inside. They review your symptoms, check your medical history, and sometimes do a physical exam to be sure of the cause. If you experience severe pain in this area, it is important to see a healthcare provider so they can rule out serious problems and decide on the best way to treat your pain.
