Should you worry about pain in your lower right abdomen?

Lower right abdomen – or tummy – pain may be a sharp, cramping or dull pain that comes and goes. It can be triggered by certain things like eating, or you may feel it all the time.

It’s medically known as right lower quadrant pain or sometimes, right iliac fossa pain, which refers to pain felt in a smaller area in the lower right corner of your tummy near your hip bone.

There are lots of different causes of pain in lower right abdomen, some of which you can treat easily at home, like constipation and trapped wind. But some causes are more serious like appendicitis, which can be life-threatening if it isn’t treated in time.

What could cause it

You’ve got different organs and tissues in your tummy, all of which may be the cause of pain in your lower right abdomen – from your gut to your kidneys, your tummy muscles and your reproductive organs.

Several conditions can affect your gut. Some, like constipation, are easy to treat with simple lifestyle changes, while more serious problems like appendicitis may need emergency treatment.

Here are some of the most common causes of pain in lower right abdomen.


Your appendix is a small, thin pouch that’s connected to your large intestine (where your poo forms). When your appendix swells and becomes painful, it’s called


Symptoms of appendicitis usually start in the middle of your tummy as a pain that comes and goes. It usually moves to your lower right abdomen where your appendix is. This pain can become constant and severe.

You may also:

  • feel sick
  • lose your appetite
  • be constipated or have diarrhoea

It’s not known what causes appendicitis, but it may be something that blocks the entrance to your appendix like a piece of poo or a swollen gland.

Sometimes, if it’s not treated in time, your appendix may burst, which can be life-threatening. So see a doctor urgently if you have very bad abdominal pain or bad pain with a



is when you have hard poo that’s difficult to pass. You may also not poo very often – less than 3 times per week. Other than pain in your lower tummy, you may also feel bloated or sick (nausea) when you’re constipated.

There are lots of causes of constipation, but sometimes there’s no obvious cause. Common causes include:

Trapped wind

You normally have some gas in your bowels, as it’s a part of your digestive system. And it usually builds up when you swallow air while eating and drinking – this is known as trapped wind. This gas travels through your gut and comes out as farts


When an air bubble gets stuck in your gut, it can cause pain wherever it’s trapped, including in your lower tummy. Other gas-related symptoms you may get include a

bloated stomach
and burping.

Causes of trapped wind include:

  • foods that increase gas in your gut, including broccoli, soluble fibre like fruit, peas and beans, and starchy food like potatoes
  • a
    lactose intolerance
    (a type of sugar usually found in dairy products)
  • a fructose intolerance (a sugar found in foods like fruit)
  • certain medicines like lactulose
    (a laxative)


Gastroenteritis – also known as a tummy bug – can cause cramp-like tummy pains that often get better after you’ve had a poo. It’s usually caused by a virus, but it can be caused by bacteria too. You can get it from food (food poisoning), infected water or from another infected person’s poo or vomit.

Other symptoms of a tummy bug include:


is a common condition that causes a collection of symptoms related to your gut. It’s not clear what causes it, but it’s thought to be linked to oversensitive nerves in your gut, stress, a family history of IBS and food passing through your gut too quickly or slowly.

Symptoms include:

  • tummy pain
  • bloating, burping or farting
  • changes in your poo habits – like diarrhoea, constipation or a mix of the 2

Female-specific causes of lower right abdominal pain

Your reproductive organs, including your womb (uterus), ovaries and fallopian tubes, lie in your pelvis or lower tummy. So if you have a problem with these organs, you may feel pain in your lower right abdomen. These include:

  • ovulation pain
    (mittelschmerz) – you get this pain on one side of your lower tummy when an ovary releases an egg
  • a twisted ovary
    (ovarian torsion) – this is when your ovary twists around ligaments. It’s very painful and a medical emergency
  • period pain
  • pelvic inflammatory disease
    (PID) – an infection usually caused by a
    sexually transmitted infection
  • endometriosis

  • an
    ectopic pregnancy
    – when an egg that’s been fertilised by a sperm implants outside of your womb. It’s an emergency, so if you’ve got lower right abdominal pain and you’re pregnant, see a doctor immediately

Male causes

Problems with your testicles (testes) may cause pain in your testicles and in either your lower right or left abdomen. These conditions include:

  • testicular torsion – when your testicle twists, it can cause serious pain. It’s an emergency, so get medical attention immediately
  • epididymo-orchitis – an inflammation of your testicle or the tube surrounding it (epididymis), which is usually caused by an infection
  • a

Your health questions answered

  • Why do I have stabbing pain on the right side of my abdomen during my period?

    Period pains are common and can vary in how painful they are and what they feel like. They’re a normal part of your period cycle and happen when your womb tightens (contracts) to get rid of the womb lining that’s built up, which you’ll see as blood. You’ll usually feel cramps in your tummy area, but sometimes, the pain may be more sharp and intense. If you find that the pain is very bad, or only ever on one side of your tummy, it may mean you have an underlying condition like fibroids (non-cancerous growths that grow in or around your womb) or endometriosis. So see a doctor if you’re in a lot of pain during your period, the pain isn’t going away after your period has stopped or you feel the pain only on one side of your tummy.” Read more about the treatment for endometriosis.
