Irritable bowel syndrome (IBS) - Symptoms 

Symptoms of IBS 

The symptoms of IBS are usually worse after eating and tend to come and go in episodes.

Most people have flare-ups of symptoms that last a few days. After this time, the symptoms usually improve, but may not disappear completely.

In some people, the symptoms seem to be triggered by something they have had to eat or drink. 

Read more about IBS triggers.

Main symptoms

The most common symptoms of IBS are:

  • abdominal (stomach) pain and cramping, which may be relieved by having a poo
  • a change in your bowel habits  such as diarrhoeaconstipation, or sometimes both
  • bloating and swelling of your stomach  
  • excessive wind (flatulence)
  • occasionally experiencing an urgent need to go to the toilet
  • a feeling that you have not fully emptied your bowels after going to the toilet 
  • passing mucus from your bottom 

Additional problems

In addition to the main symptoms described above, some people with IBS experience a number of other problems. These can include:

  • a lack of energy (lethargy)
  • feeling sick
  • backache
  • bladder problems (such as needing to wake up to urinate at night, experiencing an urgent need to urinate and difficulty fully emptying the bladder)
  • pain during sex (dyspareunia)
  • incontinence

The symptoms of IBS can also have a significant impact on a person's day-to-day life and can have a deep psychological impact. As a result, many people with the condition have feelings of depression and anxiety.

When to see your GP

You should see your GP if you think you have IBS symptoms, so they can try to identify the cause.

They can often do this by asking about your symptoms, although further tests are occasionally needed to rule out other conditions.

You should also visit your GP if you are feeling anxious or depressed. These problems rarely improve without treatment and could make your IBS symptoms worse.

If you have other symptoms  including unexplained weight loss, a swelling or lump in your stomach or bottom, bleeding from your bottom, or signs of anaemia – you should see your GP right away, as these can sometimes be a sign of a potentially more serious condition.

I have had IBS for a while now as part of my Fibromyalgia Symptoms. Sometimes its not too bad and other times like now its extremely bad. It has been so bad the last two days that i am bleeding with it. When i have told the Doctor in the past about the bleeding he said i am possibly tearing a little with it being so violent and often, i know this is only temporary and i have been thoroughly examined because of the bleeding. It hurts a lot though. Make sure if you have any bleeding at all no matter how small to tell the doctor as it may be something more serious. Thankfully mine isnt. Just wish it would go away.

I thought I am suffering from gastric before I go for medical examinations. Now I found to know that I have IBS. I am suffering from this terrible disease for more than 5 years. I hate travelling long because it makes the disease worse. Severe abdominal pain, bloating, irregular bowel habit - sometimes constipation and diarrhea. I fully accept the connection between stress and IBS. These medicines give temporary relieve. Is there any medicine for permanent relieve....?

I have suffered with IBS and depression for many years and there is definitely a link between the two. When depression comes on my IBS symptoms are much more active. It took was a few years before I fully appreciated the connection between the two! That said it still doesn't make it any easier to deal with. I tend to suffer mainly with constipation rather than diarrhea, but unusually I am currently going through a patch where both symptoms are flaring up and it is extremely debilitating. I know my concerns and fears with IBS are increased with my depressive nature as there have been many occasions when anxiety has lead me to believe I am suffering with all sorts of nasties!

I've suffered with IBS since I started university when I was 19 and it still flares up now 3 years later. Its worse when I'm stressed about exams, or travelling so I'm fairly certain stress is the trigger for me. That and too much dairy products like cheese or milk makes it worse too. It's managable but its a pain because you have to be so careful about what you eat!

I have suffered from IBS for a little time of around 6 months and unfortunately only 17 and has left me with high anxiety. I wanted to say IBS can effect teens and can be very scary!
My symptoms started by a high increase in wind when I never really did before but I figured it would pass (I wish) I then started the get serve cramping where I would physically feel I was dying and be crying in pain. I also experience on and off constipation and diarrhea, the feeling of my bowl constantly doing something and that it is never 'empty' and now rarely feel well or normal.
I am now very anxious to stay away from home or leave the house in case cramps start or bowl troubles especially in places such as exams, dinners, and away without my parents.
I was wondering if anyone has any tips of dealing with the anxiety and worry of IBS and how they discovered their triggers; my onsets don't seem to be linked with stress, food or other sources.

I think I am getting this, today I went a lot straight after eating a salad and had tummy cramps and even though completely been, I still feel like full. This also happened couple of weeks ago at 3am. I was in pain and on toilet for a while. and a few days before that, but even though if I have examination, I know from a friend who has this, there is no cure.

I've suffered with IBS for quite a long time. It was diagnosed during examination when I went to the doctors about it. I take Mebeverine when needed, and I also take Pepto Bismol which can sometimes help. I get symptoms of feeling like the bowel is not fully emptied after going to the toilet, constipation, bloating, wind, urgent need to pass stools, and sometimes, diarrhoea. I tend to get flare-ups when stressed, when it's hot, or sometimes, for no apparent reason.

I have lived with IBS for nearly 4 yrs, My NHS GP was brilliant, when I started experiencing diarrhoea my GP quickly got me 3 hospital appointments in 3 weeks, and this was around the Christmas time, because there was a history of cancer in the family. After 3 internal camera's inside my body ( I am now 65 yrs ) I got the all clear from 2 different hospitals, and it was said that I suffer from IBS, with her help I quickly realised that living with IBS was a self help thing, so I changed my diet, I started eating Kelloggs Special K mixed with equal amounts of Kelloggs Just Right with Alpro Soya, and this made my stomach feel good, I started taking an Actimel every day, I also eat brown wholemeal bread sandwiches. I stopped eating baked beans, sweetcorn and peas and I cut down on cows milk very important, and in the main I am diarrhoea free, but my IBS does flare-up now and then, but you have to live with it. I has to stop eating curry's and chilli con carne. This started in December 2010. I cannot thank the NHS Hospitals Central Middlesex, Park Royal, and the Northwick Park Hospital. From Mr David Travers, aged nearly 66, still working a 38 hr week and paying full taxes.
