How serious is it?

Pain in the lower left abdomen is when you feel pain on the left-hand side of the bottom half of your abdomen (tummy). Sometimes, people may refer to it as pain in their lower left stomach, but your stomach is actually higher up in your abdomen.

You may feel a cramping, dull, sharp or stabbing pain in your lower left abdomen that may be constant or go away and then return. And sometimes, it may start in another part of your body like your testicles and then move upwards. Or you may feel it in your lower left abdomen and in your back at the same time.

Pain in your lower left abdomen is medically known as left lower quadrant pain or left iliac fossa pain (which is, more accurately, a smaller area of pain that you may feel very low down on the left of your tummy near your hip bone).

Common causes of pain in your lower left abdomen include gut problems like constipation or

– these may go away without any treatment or with self-care. But more serious causes like
diverticular disease
need a doctor’s advice. And other very serious causes like an
ectopic pregnancy
or testicular torsion will need emergency medical care.

Causes of lower left abdomen pain

Gut problems

Your gut is made up of your stomach, small and large intestines and your rectum, where your poo is stored. If you have a problem with any of these organs, it can cause lower left abdominal pain. This includes less serious issues like mild infections, trapped wind and constipation and more serious problems like cancer.

Sometimes, these conditions will cause pain all over your abdomen and at other times, you’ll feel the pain just on one side. They include:

  • constipation
    – when your poo is too hard, which makes it difficult to poo. Sometimes, there’s no obvious cause, but it’s usually caused by not eating enough fibre and not drinking enough fluids, or not exercising enough
  • gastroenteritis
    (tummy bug) or infective colitis – these infections are usually caused by a bacteria or a virus and cause symptoms like being sick (
    ) and
  • trapped wind
    – you usually have some gas in your bowels, as it’s a normal part of your digestive system. But some people are more sensitive to it or you can get a build-up of gas from certain foods, for example
  • irritable bowel syndrome
    (IBS) – a common problem that affects your gut, causing symptoms like tummy cramps, diarrhoea and
    . Its causes aren’t clear, but it may be linked to your diet and stress levels
  • inflammatory bowel disease
    (IBD) – a term used for 2 conditions that cause inflammation in your gut,
    Crohn’s disease
    ulcerative colitis
    . Symptoms include tummy pain that keeps coming back, diarrhoea with blood, weight loss and feeling very tired
  • diverticular disease
    – caused by small bulges in your large intestine (colon). If they become inflamed or infected, it’s known as diverticulitis, which may make your tummy pain worse and give you a
  • bowel cancer
    – this cancer begins in your large bowel. The most common symptoms are blood in your poo, changes in your poo habits like diarrhoea, and a pain in your lower tummy that doesn’t go away. Most people who have these symptoms don’t have cancer, but it’s best to see a doctor if you have them

Kidney problems

If you have kidney problems, you may feel pain on just one side of your lower abdomen, either the left or the right. But, as your kidneys are behind your bowels, you’ll usually feel the pain on one side of your lower back. Kidney problems include:

  • kidney stones
    – these small crystals that form from waste products in your blood cause symptoms when they pass from your kidneys out through your pee tubes (your ureter and urethra). These include a severe pain in your back, side or lower tummy, which usually comes and goes, and blood in your pee
  • a
    kidney infection
    – this type of
    urinary tract infection
    (UTI) spreads up to your kidneys, usually from lower down in your bladder after a UTI infection like
    . Symptoms include feeling very unwell, a fever, chills, pain in your side or back just below your ribs, and sometimes, pain when you pee. Cystitis can sometimes also cause a pain in your lower left abdomen, often along with pain when you pee

Muscular problems

Your tummy muscles stretch over your abdomen from your chest to your hips. A muscle problem can cause pain in your lower left and right abdomen, including:

  • a
    – when an internal part of your body pushes through a weakness in the muscle or tissue wall surrounding it. Kinds of hernias include an
    inguinal hernia
    (groin), an
    umbilical hernia
    (near your belly button) and a muscle hernia, which can appear anywhere, including your abdomen or legs
  • a pulled muscle – this is when you strain or tear a muscle, usually after you’ve stretched or used it too much

Lower left abdomen pain in women

Your pelvis contains your reproductive organs – these include your womb (uterus), ovaries (which store and release eggs) and fallopian tubes. Sometimes, if you have pain in your left lower or right abdomen, these organs may be causing the pain.

These causes include:

  • ovulation pain
    (mittelschmerz) – you may feel this pain when your ovaries release an egg in the middle of your menstrual cycle every month
  • period pain
    – this common monthly pain is caused by your womb tightening during your period and getting rid of your womb lining
  • a twisted ovary (ovarian torsion) – when your ovary twists and cuts off your blood supply. It’s an emergency, so go to hospital if you have any
    symptoms of ovarian torsion
  • pelvic inflammatory disease
    (PID) – an infection in your womb, ovaries or fallopian tubes that’s often caused by a
    sexually transmitted infection
  • endometriosis
    – a condition where tissue similar to womb tissue grows outside your womb

Being pregnant can also be a cause of pain in your left lower abdomen. It’s a normal part of pregnancy, but if your tummy pain is really bad, see a doctor immediately. Constipation and trapped wind are usually the cause of tummy pain in pregnancy, but other common causes include:

  • ligament pain – you’ll feel this on one side of your lower abdomen as your ligaments stretch for your growing baby
  • an
    ectopic pregnancy
    – when a fertilised egg implants outside of your womb. It’s an emergency so if you’re pregnant and have any of
    these symptoms
    , see a doctor urgently
  • a
    – tummy cramps and bleeding before 24 weeks can sometimes be signs of a miscarriage. If you’re bleeding heavily, see a doctor immediately

Causes of pain in men

If you have a condition that affects your testicles (testes), you may feel pain in your left lower abdomen. These include:

  • testicular torsion – when your testicle twists on itself and cuts off its blood supply. It’s a medical emergency that needs surgery
  • epididymo-orchitis – when your testicle or the tube surrounding it (epididymis) becomes inflamed, usually due to an infection

When to see a doctor

See a doctor as soon as possible (within 24 hours if you can) if you have lower left abdominal pain and:

  • burning pain when you pee, need to pee more than usual or need to pee urgently, and your symptoms aren’t getting better after 2 days – these could be symptoms of a UTI
  • pain when you pee and you’re male, you’re a child, you’re elderly or frail, or your symptoms have come back after you’ve had antibiotics
  • a high temperature (fever)
  • pain in your back on one side, just under your ribs
  • are shaking or feel shivery
  • are vomiting (being sick) for more than 2 days or have diarrhoea for more than 7 days
  • have had sex without a condom with a new partner, or have new

  • think you may have eaten something poisonous
  • you’re vomiting and have a stiff neck or it’s uncomfortable to look at bright lights
  • have
    serious stomach pain

  • haven’t been able to pee all day
  • can’t keep any fluids down because you’re vomiting
  • feel very unwell, your heart’s beating fast, you have a fever, you feel dizzy or faint or any other signs of sepsis
  • a lump in your tummy or groin that’s very sore and you can’t push it back in

How long does it take for the pain to get better?

How long you’ll have the pain and what will happen afterwards depends on why you’ve got the pain. Some conditions will usually get better quickly with no lasting effects, including constipation, gastroenteritis or a kidney infection.

If you have a condition like IBS or IBD, the pain in your lower left abdomen may come and go in what’s known as flare-ups. Or you may have these pain flare-ups at certain times in your menstrual cycle with period pain, ovulation pain or endometriosis.

You may also need to take long-term medication for IBD or endometriosis to prevent being in pain the whole time.

Your health questions answered

  • What does pancreatic pain feel like?

    Your pancreas is found just behind your stomach at the top of your abdomen. If you get pancreatic pain, it’s because your pancreas has become inflamed due to a condition called pancreatitis. You may feel a sudden serious pain in the middle of your abdomen if you have it. You may find that the pain gets better if you curl into a ball or lean forward, but it may get worse if you’re lying down. If you’re feeling serious pain in the centre of your abdomen, see a doctor because pancreatitis – and other serious causes of pain in your lower abdomen like appendicitis – can be very serious and need urgent treatment.
