Mild food poisoning symptoms include diarrhea, nausea, and vomiting, which can be treated at home with fluids and rest. Severe symptoms may require medical attention, and food mishandling or improper preparation can lead to infectious organisms or toxins in the food. Warning signs include nausea, abdominal pain, and cramping, and patients may become dehydrated. Recovery typically occurs within three days, but severe symptoms may require more aggressive treatment.
Patients with mild food poisoning may experience diarrhea, nausea, and vomiting that typically begin to resolve within three days. People can recover from mild food poisoning at home with no special medical attention other than fluids and rest to support the immune system. If your symptoms become severe or persist for more than three days, you may need a doctor’s attention. The doctor can assess the situation and determine whether the patient needs medication or hospitalization for severe food poisoning.
Cases of mild food poisoning can be the result of infectious organisms or toxins in the food, usually because the food was mishandled or not prepared properly. Some examples may include salmonella in undercooked chicken and toxins in seafood harvested during the algae bloom. Patients may begin to notice warning signs within hours, although it can take several days for some organisms to cause disease symptoms.
Nausea is usually the first warning sign, along with abdominal pain and cramping. The patient may also experience dizziness, fever and irritability. As mild food poisoning continues, the patient may begin vomiting and may develop diarrhea. Fluid replacement is important to ensure that the patient does not become dehydrated during the food poisoning episode. If patients cannot keep fluids down, the case could be more serious.
Within three days of the onset of symptoms, the patient should begin to feel better. Mild food poisoning can cause persistent nausea and fatigue for up to ten days, but vomiting and diarrhea should stop when the patient is in the worst part of the episode. Patients may also notice that they are more sensitive to some odors and feel revulsion when exposed to the foods that made them ill. Someone who has become ill after eating potato salad, for example, may lose the taste for several weeks or months.
Signs that food poisoning may be more serious may include extremely high fever, vomiting or bloody diarrhea, or disorientation. Patients who have difficulty walking, cannot be awakened from a heavy sleep, or seem unusually distressed may need medical attention. Persistent diarrhea and vomiting that does not allow the patient to retain fluids are also a cause for concern. A healthcare professional such as a doctor or nurse can monitor the patient, collect samples for testing, and make more aggressive treatment recommendations. It may be helpful to provide a list of recent meals, in case the food poisoning is a result of contaminated foods that may be subject to recalls.
