"Question I keep on &amp;#039;feeling sick&amp;#039;. I am never actually physically sick, but this horrible sensation can strike at any time.  Having irritable bowel syndrome (IBS), I have very bad constipation.  I eat a really well balanced diet, loads of fruit, vegetables, fibre and water, but the constipation still persists.  I wonder if the &amp;#039;sickness&amp;#039; feeling is as a result of the constipation? There are no chances I might be pregnant! Answer I am sorry to hear about this recurrent feeling of nausea you have.  I think it is unlikely to be due directly to the constipation, but I think the fact that you have symptoms of irritable bowel syndrome is probably relevant.  You clearly have a good diet and most of the time I presume you are able to eat normally, as you don&amp;#039;t mention any weight loss.  It sounds as if you are free from the nausea a lot of the time and then it comes on suddenly.  IBS is a condition that is aggravated by stress, and I do wonder whether your nausea is associated with this.  It might be worth noting if your IBS symptoms and nausea ever coincide, or if either occur when you are worked up or worried.  The exact cause of IBS is debated, but the pain is probably from spasm in the bowel, although probably several factors play a part.  Treatment is also variable, but it does need sympathy and understanding. Some people find that stress makes their symptoms worse, and so trying to reduce stress can be helpful.  Some women find it is worse at certain times of their menstrual cycle. Sometimes certain foods (like dairy products) seem to make matters worse, and avoiding them can help.  Constipation and diarrhoea can both occur with IBS. Sometimes bulking agents and high fibre foods are recommended, but some patients find they just make them feel more bloated and uncomfortable.  Drugs used are usually antispasmodics, and common ones prescribed are mebeverine (Colofac is one brand) dicyclomine, peppermint oil, and alverine (Spasmonal).  I don&amp;#039;t know if you have tried all these, but they can all help to varying degrees.  Constipation may be helped by a bulking agent like Fybogel orange, but I would not recommend that you take any powerful laxatives, as they can be habit forming.  All this does not clear up the main part of your question about nausea.  I doubt that it is due to a physical problem with your stomach, and although there are drugs used to treat nausea, I would be reluctant to recommend taking medication.  There is an outside chance that you might be getting a form of non-typical migraine, in which you get some of the symptoms, like nausea, but no accompanying headache. But without knowing more about the sequence of events I could not make this assumption in your case.  I think a look at your lifestyle, trying to reduce acute stress and anxiety, and controlling your IBS symptoms as much as possible are more likely to help than drugs. I do hope this helps.
