Campylobacter infection occurs in the small intestine from bacteria called Campylobacter jejuni. It is a type of food poisoning.
People most often get infected by eating or drinking food or water that contains the bacteria. The most commonly contaminated foods are raw poultry, fresh produce, and unpasteurized milk.
A person can also be infected by close contact with infected people or animals.
If you have stomach cramps, diarrhea, fever, or nausea a few hours after eating something, chances are you may have food poisoning. Let's talk about food poisoning. Food poisoning happens when you eat food or drink water that's been contaminated with bacteria, parasites, viruses, or toxins. Most cases of food poisoning are due to common bacteria, such as Staphylococcus or E. coli. Bacteria may get into your food in different ways. Meat or poultry may come into contact with intestinal bacteria when it gets processed. Water that's used during growing or shipping may contain animal or human waste. Food poisoning may also occur when people handle your food without washing their hands properly, when food is prepared using unclean cooking utensils or cutting boards, when perishable foods are left out of the refrigerator for too long, and when people eat raw foods like fish or oysters or undercooked meats or eggs. Untreated water can also cause food poisoning. So, what do you do about food poisoning? Well, fortunately, you'll usually recover from the most common types of food poisoning within 12 to 48 hours. Your goal should be to make sure that your body gets enough fluids so that you don't become dehydrated. Don't eat solid foods until diarrhea has passed, and avoid dairy products. Drink any fluid (except milk and caffeinated beverages) to replace fluids in your body. If you have eaten toxins from mushrooms or shellfish, seek medical attention right away. The emergency room doctor will then empty out your stomach and remove the toxin. Most people will recover from the most common types of food poisoning pretty quickly. However, if food poisoning leads to dehydration because you can't keep anything down, you should seek immediate medical attention.
Exams and Tests
The infection almost always goes away on its own, and often does not need to be treated with antibiotics. Severe symptoms may improve with antibiotics.
The goal is to make you feel better and avoid dehydration. Dehydration is a loss of water and other fluids in the body.
These things may help you feel better if you have diarrhea:
- Drink 8 to 10 glasses of clear fluids every day. For people who do not have diabetes, fluids should contain salts and simple sugars. For those with diabetes, sugar-free fluids should be used with careful monitoring of blood sugars.
- Drink at least 1 cup (240 milliliters) of liquid every time you have a loose bowel movement.
- Eat small meals throughout the day instead of 3 big meals.
- Eat some salty foods, such as pretzels, soup, and sports drinks. (If you have kidney disease, check with your doctor before increasing your intake of these foods).
- Eat some high-potassium foods, such as bananas, potatoes without the skin, and watered-down fruit juices. (If you have kidney disease, check with your doctor before increasing your intake of these foods).
Most people recover in 5 to 8 days.
When a person's immune system does not work well, the Campylobacter infection may spread to the heart or brain.
