Food Poisoning Symptoms

Symptoms of Raleigh food poisoning are subject to change depending on the type of contaminant that was consumed. Affected individuals typically show symptoms within hours to days after consuming a contaminated drink or food. Some typical food poisoning symptoms include:

  • Vomiting
  • Because of an upset stomach
  • Or stomach cramps
  • Causing vomiting
  • Or diarrhea
  • A mild illness

The symptoms of food poisoning usually resolve without treatment within two days. As long as adequate fluids and electrolytes are consumed, diarrhea or vomiting can be prevented from dehydrating the body. A patient who has food poisoning symptoms that are severe should contact a doctor or healthcare provider as soon as possible for diagnosis and treatment.

It is important for patients to see a doctor if they experience any of the following Food Poisoning Symptoms:

  • A temperature of over 102°F is considered a high fever
  • Stools that appear red
  • Dehydration may result from frequent vomiting which prevents the patient from holding liquids down.
  • Prolonged diarrhea may result in dehydration.
  • Symptoms such as little or no urination, dizziness when standing up, or an excessively dry mouth or throat may indicate dehydration.

If food poisoning is mild, it may be handled at home without medical help, but if it is severe, it might need to be hospitalized and could result in long-term health problems or even death. Food poisoning can cause chronic inflammation, nerve damage, brain damage, and kidney failure, among other health issues.
