Lower abdominal pain is one of the most common reasons women visit hospitals, clinics, and diagnostic centres. The pain may be mild or severe, sudden or long-lasting, and can affect women of all ages. While some causes are harmless and temporary, others require urgent medical attention.
Because many organs are located in the lower abdomen and pelvis—including the uterus, ovaries, fallopian tubes, bladder, intestines, and appendix—it is important not to ignore persistent or severe pain. Early diagnosis can help prevent complications and ensure appropriate treatment.
This article explains the common causes of lower abdominal pain in women, associated symptoms, available diagnostic tests, treatment options, and when to seek immediate medical care.

What Is Lower Abdominal Pain?
Lower abdominal pain refers to discomfort felt below the belly button. The pain may occur on the right side, left side, centre of the lower abdomen, or across the pelvic region.
It may be:
- Sharp or stabbing
- Dull and aching
- Cramping
- Burning
- Constant
- Intermittent
The location, duration, and associated symptoms often provide important clues about the underlying cause.
Common Causes of Lower Abdominal Pain in Women
1. Menstrual Cramps (Dysmenorrhea)
Pain during menstruation is one of the most common causes of lower abdominal discomfort in women. It occurs because the uterus contracts to shed its lining.
Symptoms include:
- Cramping pain before or during menstruation
- Lower back pain
- Nausea
- Diarrhoea in some women
2. Ovulation Pain (Mittelschmerz)
Some women experience mild pain around the middle of their menstrual cycle when an ovary releases an egg.
The pain usually lasts from a few minutes to two days and often resolves without treatment.
3. Urinary Tract Infection (UTI)
A urinary tract infection can cause pain in the lower abdomen, especially around the bladder.
Other symptoms include:
- Burning sensation during urination
- Frequent urination
- Urgent need to urinate
- Cloudy or foul-smelling urine
- Blood in the urine in some cases
4. Pelvic Inflammatory Disease (PID)
PID is an infection of the female reproductive organs, usually resulting from untreated sexually transmitted infections.
Symptoms may include:
- Persistent lower abdominal pain
- Fever
- Pain during sexual intercourse
- Abnormal vaginal discharge
- Irregular vaginal bleeding
Prompt treatment is essential to reduce the risk of infertility and chronic pelvic pain.
5. Ovarian Cysts
Ovarian cysts are fluid-filled sacs that develop on or inside the ovary.
Many cysts cause no symptoms, but larger cysts may lead to:
- One-sided pelvic pain
- Bloating
- Pain during intercourse
- Menstrual irregularities
6. Uterine Fibroids
Fibroids are non-cancerous growths in the uterus that are common during the reproductive years.
Symptoms may include:
- Lower abdominal or pelvic pain
- Heavy menstrual bleeding
- Pressure on the bladder
- Frequent urination
- Difficulty becoming pregnant in some women
7. Endometriosis
Endometriosis occurs when tissue similar to the lining of the uterus grows outside the uterus.
Symptoms include:
- Severe menstrual pain
- Pain during intercourse
- Chronic pelvic pain
- Pain during bowel movements
- Difficulty conceiving
8. Ectopic Pregnancy
An ectopic pregnancy occurs when a fertilized egg implants outside the uterus, most commonly in a fallopian tube.
Symptoms may include:
- Severe one-sided lower abdominal pain
- Vaginal bleeding
- Shoulder pain
- Dizziness or fainting
This is a medical emergency requiring immediate treatment.
9. Appendicitis
Appendicitis often begins with pain around the navel before moving to the lower right side of the abdomen.
Other symptoms include:
- Fever
- Loss of appetite
- Nausea
- Vomiting
Immediate surgical evaluation is usually required.
10. Gastrointestinal Conditions
Digestive disorders may also cause lower abdominal pain, including:
- Constipation
- Irritable bowel syndrome (IBS)
- Gastroenteritis
- Inflammatory bowel disease
11. Kidney Stones
A kidney stone may cause severe pain that radiates from the side or back into the lower abdomen or groin.
Symptoms may include:
- Blood in the urine
- Pain during urination
- Nausea
- Vomiting
When Should You Seek Emergency Medical Care?
Seek immediate medical attention if lower abdominal pain is accompanied by:
- Severe or worsening pain
- Heavy vaginal bleeding
- Positive pregnancy test with abdominal pain
- Fever and chills
- Fainting or dizziness
- Persistent vomiting
- Difficulty passing urine
- Blood in stool or urine
These symptoms may indicate a serious medical condition.
How Is the Cause Diagnosed?
Your healthcare provider may recommend one or more of the following:
- Medical history and physical examination
- Pregnancy test
- Urinalysis
- Urine culture
- Full Blood Count (FBC)
- C-reactive protein (CRP)
- STI screening
- Pelvic ultrasound
- Abdominal ultrasound
- Transvaginal ultrasound
- CT scan or MRI in selected cases
Accurate diagnosis helps guide the most appropriate treatment.
Treatment for Lower Abdominal Pain
Treatment depends entirely on the underlying cause.
Examples include:
- Antibiotics for bacterial infections such as UTIs or PID
- Pain-relieving medications when appropriate
- Hormonal treatment for some gynecological conditions
- Surgical treatment for appendicitis, ectopic pregnancy, or ovarian torsion
- Lifestyle and dietary changes for some digestive disorders
- Monitoring or surgery for selected ovarian cysts and fibroids
Avoid self-medicating without a proper diagnosis, as this may delay appropriate treatment.
Can Lower Abdominal Pain Be Prevented?
Although not all causes are preventable, you can reduce your risk by:
- Practising safe sex
- Treating infections promptly
- Drinking adequate water
- Maintaining good personal hygiene
- Attending routine gynecological checkups
- Seeking medical care when symptoms first appear
Frequently Asked Questions
Is lower abdominal pain always a sign of a serious illness?
No. Menstrual cramps, ovulation pain, and mild digestive problems are common causes. However, persistent or severe pain should always be assessed by a healthcare professional.
Which side of the abdomen is more concerning?
Pain on either side may indicate a significant condition depending on associated symptoms. Persistent right-sided pain may suggest appendicitis, while severe one-sided pelvic pain may indicate an ovarian or pregnancy-related emergency.
Can ultrasound detect the cause?
Ultrasound is an important diagnostic tool for evaluating many gynecological and abdominal conditions, including ovarian cysts, fibroids, early pregnancy, and some causes of pelvic pain. Additional tests may also be required depending on the suspected diagnosis.
