Sudden sharp lower abdominal pain can be a sign of multiple underlying conditions, ranging from gastrointestinal disorders to gynecological issues. While some causes may be minor, pain accompanied by bleeding, dizziness, or weakness can indicate a medical emergency, according to gastroenterologist Dr. Vivian Asamoah, MD, FACP, ISMCP, Board certified GI, trained at Johns Hopkins Hospital, who recently highlighted the issue in an educational post on Instagram.
Dr. Asamoah explained that abdominal pain can arise from surrounding tissues due to spasms, stretching, or inflammation. Distinguishing whether the pain is gut-related or gynecological is critical for timely diagnosis.
Signs suggesting gut-related pain include:
A clear link with food, with discomfort appearing before, during, or after meals
Relief after passing stool or gas
Altered bowel habits, including constipation, diarrhea, or changes in stool consistency
Bloating and excessive gas
Cramping pain often located near the belly button or lower left abdomen
Signs pointing to gynecological pain include:
Symptoms linked with the menstrual cycle (before, during, or around ovulation)
Pain radiating to the lower back, sacrum, or rectum
Pain during sexual activity
Accompanying changes such as mood swings, abnormal vaginal discharge, or breast tenderness
Dr. Asamoah cautioned that sudden sharp pain in the lower abdomen with bleeding or weakness requires urgent medical attention, as it may signal a serious underlying condition.
The Cleveland Clinic notes that lower abdominal pain is not a disease itself but a symptom with multiple possible causes, depending on the affected organ system 1.
Irritable Bowel Syndrome (IBS): Characterized by abdominal cramping, bloating, diarrhea, or constipation. Pain is often relieved after a bowel movement.
Diverticulitis: Inflammation of small pouches in the colon can lead to sharp left-sided abdominal pain, fever, and digestive changes.
Appendicitis: Inflammation of the appendix usually begins with vague pain near the belly button that shifts to the lower right abdomen and worsens over time.
Gastroenteritis: Infections from viruses or bacteria can trigger abdominal cramps, nausea, vomiting, and diarrhea.
Menstrual Pain (Dysmenorrhea): Cramping before and during menstruation is a common cause of lower abdominal discomfort.
Ovarian Cysts: Fluid-filled sacs on the ovaries can rupture or twist, causing sudden severe pelvic pain.
Endometriosis: A condition where tissue similar to the uterine lining grows outside the uterus, leading to chronic pelvic pain and infertility.
Ectopic Pregnancy: A pregnancy occurring outside the uterus, usually in a fallopian tube, can present with sharp pain and bleeding and requires emergency treatment.
Urinary Tract Infections (UTIs): Infections of the bladder or urethra can cause pelvic pain, frequent urination, and burning sensations.
Kidney Stones: Small hard deposits in the kidneys can cause severe cramping pain radiating to the lower abdomen and groin
Lower abdominal pain is a common but complex symptom with a wide range of possible causes. As Dr. Asamoah emphasized, recognizing whether the pain is gastrointestinal or gynecological — and paying attention to red-flag symptoms — is key to avoiding delayed diagnosis and ensuring timely treatment.
