How do I recognize the onset of food poisoning?

Early symptoms of food poisoning often feel like the flu, and come within a few hours, usually no more than 12 to 18 hours, after eating the contaminated food. They will often cause feelings of headache and fatigue, and just a general feeling of being unwell. Bloating or indigestion are also some of the first ways to recognize the onset of food poisoning, followed by nausea. Food poisoning will quickly progress to full-blown symptoms, such as vomiting and diarrhea, which can last for several hours or even days. If dehydration occurs, which is very common with food poisoning, it may be necessary to visit the emergency room for intravenous fluids and treatment.

Recognizing the onset symptoms of food poisoning is important to ensure you have enough time to get home before you become seriously ill. Fever is not common with food poisoning, which is one of the easiest ways to tell early flu symptoms apart, as they are so similar. The flu will often present with a fever. Tiredness and headaches are common, and a feeling of sickness throughout the body that may be difficult to identify at first is also a regular occurrence.

In general, abdominal pain will also occur early in the onset of food poisoning. This can cause bloating or heartburn, although the pains can also be focused and sharp. Over-the-counter medications designed to treat heartburn usually won't have an effect on this symptom either, which is another clue. Nausea is very common at this point, and feelings of headache and fatigue will likely continue to worsen as well. Some people just don't notice these early symptoms of food poisoning, because it can be difficult to identify if you've never had food poisoning before.

Unfortunately, there is often little you can do once you've eaten bad food and are experiencing the onset symptoms of food poisoning. You are likely to experience vomiting or diarrhea as the body tries to expel the bacteria or other toxin from the system as quickly as possible. In some cases it will only last a few hours, while others will experience it for much longer. Dehydration is a risk that can be fatal, so it is important for anyone who is unable to keep clear liquids down, or finds that their urine output is decreasing, to go to the emergency room for treatment with medications and fluids. against nausea.
