There are many health conditions that can cause vomiting. If you experience frequent vomiting, tell your doctor. If you are having uncontrollable vomiting or are vomiting up blood, see a doctor at once.
Vomiting that does not happen with other signs of disease could be a condition called cyclic vomiting disorder CVS. If you have vomiting without other symptoms, talk to your doctor.

If you have this kind of weight loss, it may be a symptom of a more serious health problem. If you have a poor appetite and it is not because you're afraid of eating trigger foods, see a doctor. This is not an IBS symptom. IBS should not cause you to run a fever.
Recurrent fevers have other causes, including:. Fatigue is not the same thing as feeling sleepy. Fatigue is extreme tiredness that can be both physical and emotional. Many people with IBS say they often lack energy. Fatigue, though, is not a symptom of IBS. If you have deep, persistent feelings of fatigue, let your doctor know.
Other symptoms may be related to a different condition. If you have gas and bloating within 90 minutes of eating, diarrhea right after you eat, or pain that does not seem related to your bowel movements, talk to your doctor. People who get IBS-like symptoms after eating wheat and other foods that contain gluten should be tested for celiac disease.

Not all patients with IBS-like symptoms have experienced a prior infection. Some patients even experience IBS symptoms in the context of alternating constipation and diarrhea. You might also get a mix of constipation and diarrhea symptoms, but constipation-predominant IBS IBS-C is rare in post-infectious causes.
According to studies, individuals over the age of 60 face reduced risk. Similarly, research indicates that vomiting during the initial illness may cut the risk of IBS-PI by as much as 50 percent. It is thought that during a GI infection, there is an increase in inflammatory cells in the lining of the intestines. Under typical circumstances, these cells decrease with time. Preliminary research into the matter suggests that this inflammatory response takes longer to dissipate in cases of IBS-PI.
As with all cases of IBS, treatment is generally focused on relieving specific symptoms. Options include the use of anti-diarrheal agents such as Imodium , probiotics , and the recommendation of a low-fiber diet. The good news is that patients whose IBS is post-infectious have a more favorable prognosis than those for whom the origin of the IBS is unknown.
It is estimated that approximately half of all IBS-PI patients will return to their pre-infectious state of digestive functioning.
Recovery is less likely to happen if there is co-existing anxiety or depression. Once the infection cleared, the mice then received the protein again to see if their immune systems had become sensitized to it. The results reveal the mice now had IBS, along with digestive intolerance and increased abdominal pain. Researchers then successfully unpacked the series of events in the immune response that connects the digestion of egg white protein to the activation of the mast cells.
Significantly, this immune response only occurs in the part of the intestine infected by the disruptive bacteria. It did not produce more general symptoms of a food allergy.
Study authors then experimented with 12 IBS patients and discovered that people reacted in the same way as the mice. This can be due to:. Systemic lupus erythematosus SLE causes a variety of symptoms, depending on the part of the body that your immune system is attacking. Symptoms generally include:. Rheumatoid arthritis causes joint damage throughout the body. Symptoms include joint pain and swelling. Ankylosing spondylitis is a type of arthritis that affects the spine.
