Lower abdominal pain, experienced below the belly button, can stem from various sources, ranging from minor issues to serious conditions. Understanding its potential origins helps individuals recognize when medical advice is necessary.
Digestive System Causes
Digestive conditions frequently cause pain below the belly button. Irritable Bowel Syndrome (IBS) is a chronic disorder of the large intestine. Symptoms include cramping, bloating, gas, and changes in bowel habits like diarrhea or constipation. Infrequent bowel movements cause constipation, leading to discomfort and pain. Trapped gas can also cause sharp, cramp-like sensations.
Diverticulitis involves inflammation or infection of small pouches (diverticula) in the colon, commonly on the lower left side. Appendicitis, an inflamed appendix, typically begins around the belly button before localizing to the lower right abdomen. It is a medical emergency due to rupture risk. Infections or toxins from food poisoning or gastroenteritis can also cause abdominal pain, cramping, and other gastrointestinal symptoms.
Urinary System Causes
Urinary tract conditions can also cause lower abdominal pain. A Urinary Tract Infection (UTI), often a bladder infection, causes pain or pressure in the lower abdomen, frequent urination, and a burning sensation. Untreated UTIs can spread to the kidneys.
Kidney stones, as they move through the ureter, cause intense, radiating pain in the lower abdomen and groin. This severe discomfort can come in waves.
Causes Related to Female Reproductive Health
Female anatomy introduces specific conditions causing lower abdominal pain. Menstrual cramps (dysmenorrhea) cause throbbing or cramping pain in the lower abdomen during or just before a period, due to uterine muscle contractions. Some women also experience ovulation pain (mittelschmerz), a mild, brief discomfort occurring mid-cycle on one side.
Ovarian cysts, fluid-filled sacs on the ovaries, can cause pain, especially if they rupture or twist. Endometriosis, where uterine lining-like tissue grows outside the uterus, causes chronic pain in the lower abdomen and pelvis. Uterine fibroids, non-cancerous growths, can cause pressure or pain, sometimes with heavy bleeding.
Pelvic Inflammatory Disease (PID) is an infection of female reproductive organs, causing lower abdominal pain and unusual vaginal discharge. An ectopic pregnancy is a medical emergency where a fertilized egg implants outside the uterus, often in a fallopian tube. This causes severe abdominal pain and vaginal bleeding, requiring immediate medical intervention.
Musculoskeletal and Other Considerations
Other factors can contribute to lower abdominal pain. Abdominal muscle strain, often from overexertion, causes localized pain that worsens with movement or pressure.
A hernia, like an inguinal hernia, occurs when an organ (often intestine) protrudes through a weak abdominal wall spot. This causes a visible bulge and pain in the lower abdomen or groin. Sometimes, pain in the lower abdomen is referred pain, originating from another body part like the back or kidneys.
When to Seek Medical Attention
While many causes are not severe, certain signs warrant immediate medical evaluation. Seek prompt medical attention if pain is sudden, severe, or progressively worsens. Pain with fever, chills, persistent nausea, vomiting, or inability to keep fluids down also signals a serious condition.
Blood in stool or urine requires medical consultation. Significant changes in bowel habits, like new or severe persistent diarrhea or constipation, are concerning. Unexplained weight loss with abdominal pain also requires investigation. Any severe pain or bleeding during pregnancy needs immediate medical assessment. Any lower abdominal pain causing significant concern or interfering with daily life should be discussed with a healthcare professional.
