Food poisoning is a fairly common condition that occurs when we accidentally consume unsanitary or unsafe food, leading to poisoning or even death. The following article will help you understand the causes and signs of food poisoning, helping you detect health conditions early for timely handling.
WHAT IS FOOD POISONING? WHAT CAUSES FOOD POISONING?
What is food poisoning?
Food poisoning can be understood as a condition in which a patient becomes ill due to eating or drinking products or water contaminated with bacteria, toxins, or spoiled and rotten foods, or excess allowable doses of toxic preservatives and additives...
What causes food poisoning?
The main cause of food poisoning is eating or drinking food contaminated with bacteria or chemical pollution (heavy metals, mycotoxins...).
Some high-risk food cases that cause poisoning
SIGNS OF FOOD POISONING
Abdominal pain
In cases of food poisoning, harmful organisms can produce toxins that irritate the lining of the stomach and intestines. This can lead to painful inflammation in the stomach, causing symptoms of abdominal pain.
Abdominal pain can be a symptom of food poisoning.
However, abdominal pain is a common symptom of many medical conditions and health issues. Therefore, when this symptom appears on its own, it is not enough to conclude that you have food poisoning.
Diarrhea
Diarrhea is a common sign of food poisoning; having loose stools more than 3 times within a 24-hour period is a fairly clear indicator.
Parasitic bacteria cause poisoning and diarrhea
Diarrhea can also be accompanied by other symptoms, such as feeling a constant urge to use the bathroom, bloating, or stomach cramps. Some common bacteria causing diarrhea include E. coli, Salmonella...
Headache
Headache is a common symptom of poisoning caused by many factors including stress, excessive alcohol consumption, dehydration, and fatigue. Food poisoning symptoms can leave you fatigued and dehydrated, which can also lead to headaches.
Headaches are associated with many conditions, including poisoning
Although the exact cause remains unclear, dehydration directly affects the brain, causing it to lose fluid and temporarily shrink. You may be particularly prone to headaches if you experience both vomiting and diarrhea, as both increase the risk of dehydration.
Nausea or vomiting
Nausea from food poisoning usually occurs within 1 to 8 hours after a meal.
This sign acts as a warning signal to let your body know that you have eaten something potentially harmful. This condition can be aggravated by slow intestinal motility, which occurs when your body tries to retain toxins in the stomach.
Vomiting is a natural response that often occurs in people with food poisoning. This happens when the abdominal muscles and diaphragm contract forcefully, forcing the contents of the stomach out through the mouth. This is a protective mechanism that occurs as your body attempts to eliminate dangerous organisms or toxins it detects as harmful.
Vomiting is a sign of poisoning
In reality, food poisoning signs often lead to prolonged bouts of vomiting. Afterward, some people experience a gradual decrease in severity, while others vomit continuously even more.
Muscle pain, fatigue, chills, exhaustion
You may experience muscle pain during an infection caused by food poisoning. This occurs because the body's immune system is activated, triggering inflammation. During this process, your body releases histamine, a chemical that helps dilate blood vessels to allow more white blood cells to pass through to fight the infection.
Loss of appetite and fatigue are common manifestations of food poisoning. This happens when the immune system responds to fight off an invading infection in your body.
Body aches, exhaustion - Signs that cannot be ignored
Exhaustion is another common symptom of food poisoning that occurs due to the release of chemicals called cytokines. Additionally, this condition reduces your appetite, making you eat less, which further contributes to feeling fatigued.
Chills can occur as your body shivers to raise its core temperature. These shivers are the result of muscles rapidly contracting and relaxing to generate heat.
FIRST AID FOR FOOD POISONING
Induce vomiting
For individuals experiencing vomiting symptoms right after consuming toxic food, or patients who are still conscious and showing no severe poisoning symptoms, immediate measures should be taken to stimulate vomiting to expel all food from the stomach.
A clean index finger can be used to press against the back of the patient's tongue, or warm salt water can be given to induce as much vomiting as possible, limiting the absorption of toxins into the body.
Notes when inducing vomiting for patients
Rehydration
People with food poisoning may vomit and experience diarrhea multiple times, leading to dehydration; therefore, the patient needs to drink plenty of fluids and rest. Rehydration can be achieved using an ORS (Oral Rehydration Salts) solution prepared according to instructions.
Promptly take the patient to a medical facility for emergency care
In cases where the patient exhibits unusual symptoms such as seizures, altered consciousness, or respiratory failure, do not induce vomiting, as this can be life-threatening. Even after performing the first aid steps above, the patient remains at risk of danger at any moment. Therefore, it is necessary to take the patient immediately to a medical facility for an accurate diagnosis of the cause and timely treatment.
PREVENTATIVE MEASURES AND REDUCING THE RISK OF FOOD POISONING
Currently, the issue of unsafe food containing harmful chemicals is developing in a complex manner. Careful selection and preparation of food will help protect yourself and your family members from the risk of encountering these health problems. This includes:
- Food selection: Choose fresh, raw foods that are not spoiled, expired, and have a clear origin.
- Food storage: Store uncooked and cooked food in the refrigerator at appropriate temperatures; do not leave cooked food at room temperature for more than two hours.
- Food preparation: Follow the rule of eating cooked food and drinking boiled water. Ensure food preparation utensils are clean.
- Caution when eating out: When eating out, choose places that ensure food hygiene and safety, avoiding dirty, damp street vendors...
- Maintain cleanliness: Wash hands with antibacterial soap before eating.
Preventing potential hazards remains a paramount factor. Toxins and bacteria can contaminate raw ingredients and food at any stage. To ensure optimal control, selecting reputable ingredient sources and applying food safety and hygiene management systems throughout transportation and production is extremely important.
