With a clear fluid diet and rest, most infections resolve on their own within 24 hours. A health care practitioner should be contacted if the vomiting and diarrhea are associated with one or more of the following symptoms:
-fever,
-blood in the stools,
-signs of dehydration including lightheadedness when standing, weakness, decreased urination,
-diarrhea that lasts longer than 72 hours, and/or
-intractable vomiting that prevents oral hydration. :mrgreen: :mrgreen: :mrgreen:

How is food poisoning diagnosed?
Most times, the diagnosis of food poisoning is made by history and physical examination. Often, the patient volunteers the diagnosis when they come for medical care. For example, "I got sick after eating potato salad at a picnic" or "I drank a raw egg protein shake". :lol: :lol:

The health care practitioner may ask questions about the symptoms, when they started, and how long they have lasted. A review of systems may help give direction as to what type of infection is present. For example, a patient with numbness of their feet and weakness may be asked about whether they have opened any home canned food recently. :x :x :P :P

Travel history may be helpful to see if the patient had been camping near a stream or lake and the potential for drinking contaminated water, or if they have travelled out of the Country recently and have eaten different foods than they normally do, for example, did the patient eat raw eggs or wild game? :?: :?: :?:

Physical examination begins with taking the vital signs of the patient (such as blood pressure, pulse rate and temperature). Clinical signs of dehydration include dry, tenting skin, sunken eyes, dry mouth, and lack of sweat in the armpits and groin. In infants, in addition to the above subtle signs of dehydration may include poor muscle tone, poor suckling, and sunken fontanelle. :? :D :mrgreen: :geek:

Routine blood tests are not usually ordered unless there is concern about something more than the vomiting and diarrhea. In patients with significant dehydration, the health care practitioner may want to check electrolyte levels in the blood as well as kidney function. :twisted: :twisted: 8-)

If there is concern about hemolytic uremic syndrome, a complete blood count (hemogram, CBC) to check the red blood cells, white blood cells, and platelet count may be ordered. If there is concern about hepatitis, liver function tests may be ordered. :o :o :o

Stool samples may be useful especially if there is concern about infections caused by Salmonella, Shigella and Campylobacter, the common non traveler's diarrhea This is especially true when the patient presents with bloody diarrhea, thought to be due to infection. If there is concern about a parasite infection, stool samples can be examined also for the presence of parasites. :roll: :!: :!: :oops:

Depending on the suspected cause of the food poisoning, there are some immunological tests (for example, detection of Shiga toxins) that the CDC recommends. Other methods may be used (for example, detection of prions in tissue samples). :P :P

Maintaining good hydration is the first priority when treating food poisoning. Hospitalization may be appropriate if the patient is dehydrated or if they have other underlying medical conditions that become unstable because of the fluid or electrolyte imbalance in their body. Medications may be prescribed to help control nausea and vomiting. :cry: :cry: :? :? :?
