Ulcers, infection, hernia, appendicitis and pelvic inflammatory disease are potential causes of a burning sensation in the lower abdomen, according to Today Health, Healthline and Huron Valley-Sinai Hospital. Additional symptoms help to pinpoint the culprit and also eliminate other possibilities, per Today Health.
If the pain is right below the bellybutton or focused sharply on the lower right side, appendicitis is more likely and requires immediate medical intervention, according to Today Health. If there is a tender bulge in the lower abdomen that gets larger or more painful with time, a hernia is likely to blame, says the Huron Valley-Sinai Hospital. Hernias are more common in men, but women get them also.
Lower abdominal pain accompanied by unusual vaginal discharge indicate a fungal or bacterial infection in women, reports Healthline. Pelvic inflammatory disease is also a possibility due to a sexually transmitted infection, such as chlamydia or gonorrhea.
If the burning in the lower abdomen gets worse with hunger, an ulcer may be to blame, according to Today Health. Antibiotics or surgery may be needed to treat it, so a doctor's intervention is imperative. A doctor's care is also required if any abdominal pain is accompanied by vomiting, unexplained weight loss, bloody discharge unrelated to menstruation, or pain during urination or intercourse, warns Healthline.
