Why Do I Have Lower Stomach Pain? A Complete Guide for Women

You wake up with a dull ache below your belly button. Or the pain comes in waves, stays on one side, or appears only before your period. It is natural to ask, "Why do I have lower stomach pain?"

The answer depends on your age, your menstrual cycle, the exact location of the pain and the symptoms that come with it. In many women the cause is gynaecological, but it can also be urinary or digestive. This guide explains the most common reasons, the warning signs, and when to consult Dr. Priyanka Pachauri, a gynaecologist at Dr. Priyanka Gynaec in Moradabad.

Why Women Get Lower Stomach Pain So Often

Several organs share the lower abdomen. That is why the cause is not always obvious.

• The uterus, ovaries and fallopian tubes sit in the lower pelvis.
• The bladder lies directly in front of the uterus.
• The bowel (lower intestine and rectum) sits behind and beside these organs.
• Muscles, ligaments and nerves are shared across this region.
• Hormones change every month and affect the uterus, ovaries and gut together.

A problem in one organ can feel like pain from another.

Causes Linked to Your Menstrual Cycle

If the pain follows a monthly pattern, hormones are usually involved.

Period Cramps (Dysmenorrhoea)

• Pain starts just before or at the start of bleeding.
• Caused by uterine contractions.
• Usually settles within two to three days.
• Pain that stops you from working or studying is not something to ignore.

Ovulation Pain

• A short, one-sided ache around mid-cycle.
• Lasts a few hours to a day or two.
• Usually harmless.

Premenstrual Symptoms

• Bloating, heaviness and mild cramping before periods.
• Often comes with mood changes and breast tenderness.

Endometriosis

• Tissue like the uterine lining grows outside the uterus.
• Causes severe period pain and ongoing pelvic pain.
• May cause pain during intercourse or bowel movements.

Adenomyosis

• Uterine lining grows into the muscle wall.
• Causes heavy, painful periods and a tender, enlarged uterus.

Causes Linked to the Ovaries and Uterus

Ovarian Cysts

• Fluid-filled sacs on the ovary.
• May cause one-sided pain, fullness or bloating.
• Most are harmless, but twisting or rupture can cause sudden, severe pain.

Uterine Fibroids

• Non-cancerous growths in the uterine wall.
• Cause heaviness, pressure and heavy periods.
• Large fibroids may press on the bladder or bowel.

PCOS (Polycystic Ovary Syndrome)

• Irregular periods, acne, excess hair growth and weight gain.
• May cause bloating and pelvic discomfort.

Uterine Polyps

• Small growths inside the uterus.
• May cause irregular bleeding and cramping.

Pelvic Inflammatory Disease (PID)

• Infection of the uterus, tubes or ovaries.
• Causes lower belly pain, fever and unusual discharge.
• Early treatment protects fertility.

Uterine Prolapse

• Weak pelvic support lets the uterus descend.
• Causes dragging heaviness in the lower belly.

Causes Not Related to the Reproductive System

A good doctor also checks for other possibilities.

Urinary Causes

• Urinary tract infection: burning, frequent urge and lower belly discomfort.
• Kidney stones: severe pain that may spread from the back to the lower belly.
• Bladder inflammation.

Digestive Causes

• Constipation and trapped gas.
• Irritable bowel syndrome: cramping with diarrhoea or constipation.
• Food intolerance.
• Appendicitis: pain starting near the navel and moving to the lower right side.

Muscle and Other Causes

• A hernia: a bulge in the groin or lower abdomen.
• Muscle strain after exercise or heavy lifting.
• Stress and anxiety, which can tighten abdominal and pelvic muscles.

Which Side Is the Pain On?

Location offers clues, but it never replaces an examination.

Lower left side

• Ovarian cyst or ovulation pain.
• Constipation or bowel inflammation.
• Endometriosis.
• Urinary stones.

Lower right side

• Ovarian cyst or ovulation pain.
• Appendicitis, which is urgent if pain is severe and worsening.
• Ectopic pregnancy if you could be pregnant.

Centre of the lower belly

• Period cramps.
• Fibroids.
• Bladder infection.
• Pelvic infection.

Pain spreading to the back or thighs

• Endometriosis.
• Pelvic inflammation.
• Kidney-related causes.

Why Do I Have Lower Stomach Pain When I Am Not Pregnant?

Many women assume pain must mean pregnancy, but pain is common without it.

• Period-related cramps and hormonal changes.
• Cysts, fibroids or endometriosis.
• Infections of the urinary or reproductive tract.
• Constipation or bowel problems.
• Stress and muscle tension.

A urine pregnancy test is a simple first step if your period is late.

Lower Stomach Pain by Age Group

Teenage girls

• Period cramps are the most common cause.
• Irregular periods in the first years are common.
• Severe pain should still be evaluated.

Women in their 20s and 30s

• Cysts, PCOS, endometriosis and infections are frequent.
• Pregnancy-related causes must be considered.
• Fertility concerns may appear.

Women in their 40s

• Fibroids, adenomyosis and heavy bleeding are more common.
• Perimenopausal hormonal changes begin.

After menopause

• New pelvic pain deserves prompt examination.
• Postmenopausal bleeding needs urgent evaluation.
• Prolapse, infections and other uterine or ovarian causes are possible.

Lower Stomach Pain During Pregnancy

Often normal:

• Mild stretching or pulling as the uterus grows.
• Light cramping in early pregnancy.
• Round ligament pain along the sides of the lower belly.

Needs prompt medical review:

• Severe or one-sided pain with spotting or bleeding.

• Leaking fluid with pain.

Red Flags: Do Not Wait

Seek emergency care immediately if you have:

• Sudden, severe lower abdominal pain.
• Fainting, dizziness or cold, clammy skin.
• Heavy bleeding that soaks pads quickly.
• High fever with severe pain.
• Severe pain with a positive pregnancy test.
• A hard, rigid abdomen with repeated vomiting.
• Pain that keeps worsening instead of settling.

Signs You Should Book a Consultation Soon

• Pain lasting more than a few days.
• Pain that returns every month.
• Pain that needs regular painkillers.
• Heavy, prolonged or irregular periods.
• Bleeding between periods.
• Pain during intercourse.
• Persistent bloating or swelling in the lower belly.

How Doctors Find the Cause

Diagnosis is a step-by-step process:

• History: pain pattern, periods, pregnancies, bowel and urine habits.
• Examination: gentle abdominal and pelvic check with your consent.
• Pelvic ultrasound: often the first and most useful test.
• Urine and blood tests: to check for infection, anaemia or pregnancy.
• Hysteroscopy or laparoscopy: only if other tests cannot explain the pain.

Dr. Priyanka Gynaec uses high-definition 3D laparoscopy and 3D and 4D ultrasound to support accurate diagnosis.
