Food poisoning is a type of illness that you get from something you ate or drank. This is usually caused by harmful germs or bacteria that contaminated what you consumed. Food poisoning can be prevented by consuming food that is freshly prepared and being vigilant around street food.<\/p>\n Food poisoning is a foodborne acute illness, meaning it can happen suddenly and last for a short time. In most cases, food poisoning only lasts less than a week, and most people recover on their own without receiving medical treatment.<\/p>\n In more serious cases, however, it is highly recommended to seek medical help to prevent further complications<\/a>.<\/p>\n A stomach bug is a highly contagious intestinal infection.Similar to food poisoning, you can get a stomach bug from consuming contaminated food and drinks. You can also get infected from sharing utensils or food with someone who has a virus that causes the illness (e.g. noroviruses, or rotavirus).<\/p>\n It is also called \u201cviral gastroenteritis,\u201d but it is commonly called \u201cstomach flu.\u201d It\u2019s important to remember that stomach flu is not the same as the flu (influenza). Getting a flu vaccine will not protect you from contracting a stomach flu.<\/p>\n Diarrhea, stomach pain or cramps, and nausea are some of the common symptoms of food poisoning. These symptoms typically appear about two to six hours after eating or drinking something that was contaminated or not properly handled.<\/p>\n The most common symptoms of food poisoning are:<\/p>\n Food poisoning can also lead to dehydration due to diarrhea and vomiting. Be sure to drink plenty of fluids and electrolytes when recovering from the illness.<\/p>\n Less common but more serious symptoms are:<\/p>\n If you are experiencing severe symptoms of food poisoning, seek help from a doctor immediately.<\/p>\n Further read: A Guide to Food Poisoning Symptoms for Expats in Thailand<\/a><\/p>\n Watery diarrhea, nausea, and vomiting are some common symptoms of a stomach bug. The symptoms for stomach bugs typically appear within one to three days after exposure to the virus. In most cases, stomach bugs are harder to detect since you can\u2019t backtrack on what you ate or drank.<\/p>\n The most common symptoms for a stomach bug are:<\/p>\n More serious symptoms are:<\/p>\n Understanding the difference between food poisoning and a stomach bug is crucial for determining the right treatment. While both conditions may cause similar symptoms, they differ in origin, onset, and contagiousness.<\/p>\n Food poisoning often follows the consumption of contaminated food or beverages, and symptoms can appear suddenly within hours. On the other hand, stomach bugs are caused by viral infections and are highly contagious, spreading through close contact with infected individuals.<\/p>\n Seek medical help if you are experiencing serious symptoms of gastroenteritis.<\/p>\n Contamination can happen from any point from when the ingredients are picked out from the farms to when the food is prepared and served. Food can be contaminated at any time and any place, even at home. Here are some ways on how food gets contaminated:<\/p>\n It is important to wash your hands after using the toilet. Feces, germs or bacteria that remain on the hands can be transferred when preparing food or serving food, leading to contamination and foodborne illnesses. Handwashing is crucial to prevent getting sick.<\/p>\n If the kitchen or dining areas are not regularly disinfected, the bacteria or virus that causes foodborne illnesses can linger and infect you. Also, it is important to clean cooking utensils such as knives, cutting boards, and other kitchen tools to avoid cross-contamination between ingredients.<\/p>\n In most cases, certain foods that have been left out for too long in warm temperatures can cause bacteria to grow fast, increasing the risk of contamination. Spoiled food from prolonged storage in heat or even in the refrigerator can also cause foodborne illnesses.<\/p>\n Treatment for food poisoning can differ based on how severe your symptoms are and what caused the illness. If you have a more serious case, you may be prescribed medication to help remove the virus and bacteria in your system.<\/p>\n It\u2019s important to drink plenty of fluids when recovering from food poisoning. Water and electrolytes can help in avoiding severe dehydration that\u2019s caused by diarrhea and vomiting. If you need medication, your doctor may prescribe the following:<\/p>\n Contact your doctor immediately if you experience the following symptoms of food poisoning:<\/p>\n It is advised to seek medical help if you contracted food poisoning shortly after visiting a developing country, like Thailand.<\/p>\n Here is our guide to Food Poisoning First Aid Services in Thailand<\/p>\n In most cases, you can treat a stomach bug at home with plenty of rest and drinking lots of fluids. Since you can get dehydrated from a stomach bug, it\u2019s important to restore your body\u2019s hydration balance by drinking plenty of water and electrolytes.<\/p>\n Avoid sugary drinks, caffeine, and alcohol while recovering from a stomach bug. These drinks do not replace lost electrolytes. Coconut water is a good option for electrolytes, and it is low on sugar.<\/p>\n Once you start feeling a bit better, you can slowly introduce bland food to your system. Here\u2019s a list of food that\u2019s easy to consume when recovering from a stomach bug:<\/p>\n Avoid any food that may upset your stomach like dairy, spicy food, and fried food.<\/p>\n Be mindful of your food and drinks to avoid food poisoning, especially while in Thailand. Common places that might have contamination are street vendors and eateries that look questionable. For drinks, opt for bottled water to ensure the water is clean and there is no contamination.<\/p>\n Good hygiene practices are crucial for preventing food poisoning. Always wash your hands after using the restroom and before eating. If you are buying fruits and vegetables, make sure to wash them thoroughly before cooking and opt for fresh options.<\/p>\n Additionally, if you are travelling to Thailand and you are new to the local cuisine, it\u2019s important to do research to understand how Thai dishes are typically made and what ingredients could cause food poisoning.<\/p>\n By being vigilant on what you consume, you can enjoy what Thailand has to offer without worrying about getting sick.<\/p>\n The best way to prevent catching a stomach bug is to practice good personal hygiene<\/strong>. Wash your hands before eating, especially if you went to the bathroom before a meal. You can reduce the risk of getting the stomach flu and spreading the virus to others by doing so.<\/p>\n Since stomach bugs are contagious, it\u2019s best to avoid any interaction with other people until you are fully recovered to avoid spreading the illness further. Stomach bugs have a higher chance of infecting others than food poisoning due to their contagious nature.<\/p>\n While the two illnesses seem similar in terms of their symptoms and causes, you can identify whether you have food poisoning or a stomach bug based on what food or drink you have consumed. Here are some ways in which food poisoning and a stomach bug differ from each other:<\/p>\n For most food poisoning cases, the source of the illness is from food that\u2019s been contaminated by bacteria like salmonella, E. coli, norovirus, listeria, and campylobacter – the most common cause of food poisoning.<\/p>\n On the other hand, stomach bugs are usually caused by viruses like rotavirus, norovirus, adenovirus, and others that may be transmitted through consuming contaminated food and drinks or by contacting unsanitized objects. The most common viruses that cause stomach bugs are norovirus and rotavirus.<\/p>\n Food poisoning<\/strong> usually takes effect after six hours of consuming contaminated food<\/strong>, while stomach bug<\/strong> symptoms begin one to two days after being exposed to the virus<\/strong>. Most often, these illnesses come without warning.<\/p>\n It may take from a few days to up to two weeks to fully recover from a stomach bug, while food poisoning typically lasts within 12 to 48 hours in healthy people.<\/p>\n However, if you experience serious complications, you could be sick with food poisoning for 10 days or more. It\u2019s best to consult a doctor if you experience worsening symptoms to get the right treatment for you.<\/p>\n Most of the time, you can treat a stomach bug at home with plenty of rest and fluids, while food poisoning may need medication to help you pass the illness. Both illnesses require rest and fluids, but there are different treatments to help with different symptoms.<\/p>\n If you\u2019re dealing with a stomach bug or food poisoning, some home remedies include:<\/p>\n For food poisoning specifically, treatment includes certain medication to help ease symptoms and flush out the virus or bacteria in your body. Consult your doctor on prescribing you the right medication for food poisoning.<\/p>\n Whether you are a first-time traveller or an expat looking to relocate in Thailand, it\u2019s important to prepare for any possibilities of getting infected with food poisoning or a stomach bug. Since these illnesses can happen at any point, protect yourself by preparing the following:<\/p>\n Securing an international health insurance plan<\/a> before you travel to Thailand can help alleviate your worries on expensive medical treatments. Most private hospitals and clinics can be quite expensive, especially if you get admitted to stay at a hospital overnight.<\/p>\n The good news is, a health insurance policy will most likely cover foodborne illness. Be sure to consult with an insurance broker, like Pacific Prime<\/a>, on which insurance plans, coverage, and benefits would be best for you.<\/p>\n Further read: Food Poisoning and Your Health Insurance in Thailand<\/a><\/p>\n While there is the option of visiting a pharmacy or a doctor in Thailand, it\u2019s best to bring your own medication or remedies in case you can\u2019t find the right medicine due to language issues or allergies.<\/p>\n Also, having your medication readily available can help you treat your symptoms immediately. You can avoid worsening symptoms and have peace of mind knowing that you can rest easy and keep yourself safe.<\/p>\n Thailand is considered to have one of the world\u2019s best healthcare systems, which offers universal health coverage to all Thai citizens that meet certain qualifications. However, foreigners and expats are not eligible to access Thailand\u2019s universal health coverage.<\/p>\n This is where having private health insurance can come in handy. For short-term visitors, or tourists, travel medical insurance<\/a> is great to avoid any unnecessary medical expense in the event of a medical emergency.<\/p>\n Your health matters and it\u2019s important to be prepared for any scenario, whether you catch food poisoning or gastroenteritis.
