Food poisoning is a common ailment that occurs when contaminated food or water is consumed. While it is usually mild and goes away without medication, severe cases may require a trip to the hospital. The treatment for food poisoning in hospitals involves rehydration through IV fluids, diagnostic testing to identify the pathogen, and, in some cases, antibiotics for bacterial infections. The remainder of this article will delve into the details of hospital treatment for food poisoning, including the circumstances that warrant a hospital visit and the specific procedures employed during treatment.

What You'll Learn
Oral history and physical exam
When seeking medical care for food poisoning, the first medical contact will likely be with a pediatrician, a family medicine doctor, or a hospital emergency room. During this initial consultation, the medical professional will take an oral history, perform a physical exam, and recommend diagnostic testing.
Oral History
The oral history involves a detailed discussion about the patient's symptoms and the specific foods consumed in recent days. The medical professional will inquire about the presence of similar symptoms in other household members and ask about recent travel, contact with animals, consumption of antibiotics, and any fever or bloody bowel movements. This information helps assess the potential sources of infection and the severity of the condition.
Physical Exam
The physical examination focuses on checking for signs of dehydration, which is a common complication of food poisoning due to vomiting and diarrhea. The patient's blood pressure and pulse will be monitored to assess dehydration levels. Additionally, the neurological status will be evaluated, and in some cases, a digital rectal exam may be performed to check for blood in the stool, which could indicate an infection caused by bacteria or parasites.
The physical exam, along with the oral history and diagnostic tests, guides the medical professional in determining the appropriate treatment plan for the patient's food poisoning.

Blood, urine, and stool tests
Food poisoning is caused by the consumption of food or water contaminated with bacteria, viruses, parasites, or toxins. Symptoms include vomiting, diarrhea, or both, and usually appear within two to six hours of ingesting contaminated food or liquids. In most cases, food poisoning does not require medical treatment and can be managed at home by staying hydrated and getting rest.
However, in more severe cases, hospitalization may be necessary to receive intravenous (IV) fluids if diarrhea and vomiting are persistent. Hospitals may also administer antibiotics or antiparasitic medications in the case of certain infections.
To diagnose food poisoning, doctors may rely on a patient's symptoms, medical history, and physical examination. Additionally, blood, urine, and stool tests may be conducted to confirm the diagnosis and identify the specific cause of the food poisoning.
Blood Tests
Blood tests can reveal signs of certain infections or complications such as dehydration. A blood culture may be performed if the patient has a fever. Other blood tests, such as a complete blood count (CBC) with differential, serum electrolyte assessment, and BUN and creatinine levels, can help assess the inflammatory response and the degree of dehydration.
Urine Tests
Although less commonly mentioned, urine tests may be used to assess dehydration or kidney function, which can be affected by severe food poisoning.
Stool Tests
Stool tests are often used to diagnose food poisoning. If a stool sample shows the presence of white blood cells (WBCs) or blood, or if patients have a fever or persistent symptoms, a bacterial culture for enteric pathogens, such as Salmonella, Shigella, and Campylobacter organisms, may be performed. Stool tests help identify the specific bacteria, parasite, or virus causing the food poisoning, guiding treatment decisions.

IV fluids
Food poisoning can be an extremely unpleasant experience, causing symptoms such as nausea, vomiting, and diarrhoea. These symptoms can lead to a loss of fluids and dehydration, which is dangerous and requires immediate medical attention.
IV therapy can be administered in-clinic or through mobile services, providing the convenience of receiving treatment in the comfort of your own home. Mobile IV therapy is a popular option, especially for those who wish to avoid a trip to the hospital or emergency room. These services offer fast response times, often providing treatment within an hour of booking.
The IV fluids contain a blend of vitamins, including Vitamin C, Vitamin A, Vitamin B complex (including B6 and B12), Vitamin D3, Vitamin E, and Vitamin K1. These vitamins help to support the immune system and improve nausea and vomiting symptoms associated with food poisoning.
In addition to vitamin supplementation, IV fluids also contain a mixture of water and sodium chloride (saline) to replenish fluids lost due to vomiting and diarrhoea. This helps to restore normal body function and alleviate dehydration symptoms.

Antibiotics
It is important to note that antibiotics should not be taken lightly, and they are typically reserved for severe cases of food poisoning or those with a high risk of complications. Some complications that may arise from food poisoning include blood clots in the kidneys, meningitis, or sepsis. In these cases, antibiotics can be life-saving.
Additionally, if food poisoning is caused by a parasite, antiparasitic medications may be prescribed. These include metronidazole, tinidazole, furazolidone, or albendazole for giardia infections, and sulfadiazine plus pyrimethamine, sulfonamides, sulfamethazine, or sulfamerazine for toxoplasma infections.
The decision to prescribe antibiotics or other medications is made by medical professionals based on the patient's symptoms, the results of diagnostic tests, and the severity of the condition. It is important to seek medical advice if you suspect food poisoning and not to self-medicate, especially with antibiotics, as their overuse can lead to antibiotic resistance.

Dehydration prevention
Dehydration is a common complication of food poisoning, as the body purges toxins through vomiting and diarrhoea. To prevent dehydration, it is important to drink plenty of fluids. Water and electrolyte drinks are recommended to stay hydrated. In severe cases of dehydration, hospitals may administer IV fluids.
Mild dehydration symptoms include a headache, fatigue, and dry mouth. It is important to look out for these signs and seek medical help if they occur. Blood and urine tests can also be carried out to check for dehydration.
In addition to drinking fluids, it is recommended to rest and avoid solid foods until symptoms improve. This allows the body to recover and helps prevent further dehydration.
For those with severe food poisoning, antibiotics may be prescribed to treat bacterial infections such as E. coli, Salmonella, or Listeria. However, most cases of food poisoning are mild and do not require medication.
Food poisoning typically lasts one to ten days and often resolves without treatment. However, severe or persistent symptoms may indicate a more serious condition, and medical attention should be sought if symptoms do not improve.

Frequently asked questions
If you think you have food poisoning, it is important to stay hydrated and get plenty of rest. If your symptoms are mild, you may not need to seek medical treatment, as food poisoning often goes away on its own. However, if your symptoms worsen or persist, you should contact your doctor or visit an urgent care center.
If you are experiencing severe symptoms such as persistent vomiting and diarrhoea, difficulty swallowing or breathing, muscle paralysis, or blurred vision, you should seek emergency medical care or call an ambulance. You may need to be hospitalised to receive IV fluids and more intensive care.
During your first medical contact, a doctor will take an oral history, perform a physical exam, and order diagnostic tests. You will likely be asked detailed questions about your symptoms and recent food intake. Diagnostic tests may include blood and urine tests, abdominal X-rays, and stool samples to identify the source of the poisoning.
