Food poisoning occurs when you eat food contaminated with harmful bacteria, viruses, or parasites. Fortunately, most cases are mild and resolve without needing medical attention. The most common culprits are bacteria like salmonella or E. coli, but viruses and parasites can also lead to food poisoning. Symptoms may start within hours of eating contaminated food, or they could take several days or even weeks to appear, depending on the type of contaminant.

Nausea

Nausea is typically one of the first symptoms of food poisoning. It can cause a constant feeling of an upset stomach, leaving you feeling sick and sometimes dizzy. After consuming tainted food, nausea might set in quickly, but it more commonly starts a few hours later. Drinking clear fluids like water or ginger tea can help ease this sensation. Once the nausea starts to fade, eating light, bland foods like crackers or toast may help settle your stomach.

Diarrhea

Diarrhea is another common symptom, and it’s the body’s way of expelling harmful bacteria or toxins. Though uncomfortable, diarrhea helps clear out the digestive system. It’s crucial to stay hydrated, as diarrhea can lead to dehydration. Drinking water or oral rehydration solutions can help replenish lost fluids and electrolytes.

Stomach Cramps

Stomach cramps often accompany food poisoning and are caused by the body’s muscles contracting as it tries to flush out the infection. These cramps can be sharp and occur in waves or as continuous discomfort. In most cases, stomach cramps last a few hours, and during this time, you might also experience nausea, vomiting, or diarrhea.

Loss of Appetite

It’s natural to lose your appetite when you have food poisoning. After eating something contaminated, your body may reject the idea of food altogether for a while. Despite the lack of hunger, your body still needs energy to recover, so try to eat easy-to-digest foods like broths or plain bread once your stomach feels more stable.

Weakness

Weakness is a common symptom of food poisoning and is often caused by dehydration or the body’s efforts to fight off the infection. When combined with vomiting and diarrhea, food poisoning can make you feel extremely tired and unable to go about your daily routine. If you can’t keep fluids down, it’s essential to seek medical help to avoid complications from dehydration.

Fatigue

Fatigue can set in as your body works hard to eliminate the toxins from your system. This symptom is often worsened by dehydration or a lack of nutrients due to vomiting or diarrhea. Rest is one of the best remedies for fatigue, allowing your body to focus its energy on healing and recovery. Even if frequent bathroom trips disrupt sleep, try to get as much rest as possible.

Fever

A fever is a natural immune response when your body is fighting off an infection like food poisoning. The rise in temperature helps kill the bacteria or viruses causing the illness. During this time, staying hydrated and resting are essential for recovery. Use a cold compress to bring down your temperature if needed, and monitor your fever to ensure it doesn’t reach dangerous levels.

Sweating and Chills

Sweating and chills often accompany fever during food poisoning. These alternating sensations occur as your body tries to regulate its internal temperature to combat the infection. Though uncomfortable, this process is part of your body’s defense system. Be sure to replace fluids lost through sweating by drinking water or other hydrating beverages.

Difficulty Swallowing

In some cases, particularly with food poisoning caused by botulism or certain fish toxins, you may experience difficulty swallowing. This symptom occurs when the muscles in the throat or esophagus stiffen, making it hard to swallow or even breathe comfortably. If you notice difficulty swallowing along with other serious symptoms, seek immediate medical attention, as this could signal a medical emergency.

More Severe Symptoms

While most food poisoning cases are mild, certain symptoms indicate the need for medical attention. You should see a doctor if you notice blood in your stool or vomit, have a fever over 102°F, experience excessive vomiting that prevents you from staying hydrated, or if diarrhea lasts longer than three days. These symptoms could suggest a more severe infection that requires professional treatment.
