Appendicitis, endometriosis and inguinal hernia are some conditions that cause pain in the lower right abdomen. A few other illnesses include Mittelschmerz and diverticulitis, according to Mayo Clinic.
The inflammation of the appendix causes appendicitis. A typical symptom is naval pain that gradually radiates around the lower right abdomen area. Nausea, loss of appetite and constipation are the other signs. It is common in people between the ages of 10 and 30, states Mayo Clinic.
Endometriosis is a medical condition in which the endometrium grows outside the uterus. Common symptoms include pelvic pain, pain in the lower back and excessive bleeding. It can also result in fatigue, bloating and diarrhea during menstruation. Extreme cases can lead to infertility, notes Mayo Clinic.
An inguinal hernia occurs when soft abdominal tissue extends and bulges through the abdominal muscles. Some hernia symptoms include bulges on the side of the pubic bone, burning sensations and severe discomfort when coughing or lifting weights. Mittelschmerz is a lower abdominal pain common during ovulation and can last for up to two days. It is characterized by sharp abdominal pain with a mild vaginal discharge, according to Mayo Clinic.
Diverticulitis is an infection of the diverticula and is common in people over 40 years of age. Diverticula are small, sac-like structures that line the digestive system. The inflammation of these sacs can cause nausea, fever and intense pain in the lower right abdomen, states Mayo Clinic.
