Why does vomiting cause fever? After vomiting, fever may occur, which is a common phenomenon for young babies. This symptom can sometimes come quickly, with sudden vomiting leading to fever. At this point, parents may feel at a loss. In fact, if a baby experiences vomiting and fever, it may be due to a viral infection. Let's find out the specific reasons together.
Why does vomiting cause fever
There are many reasons that can cause vomiting in children, such as gastrointestinal infections, intussusception, pyloric obstruction, appendicitis, etc. Among them, gastrointestinal infections are the most common, including infections caused by rotavirus, adenovirus, enterovirus, etc. Eating inappropriate food is also a common cause of vomiting.
In addition to gastrointestinal diseases, diseases of other organs such as otitis media, urethritis, colds, meningitis, hydrocephalus, etc. can also cause vomiting. Allergies and poisoning caused by taking certain medications such as salicylic acid, iron supplements, erythromycin antibiotics, etc. can also lead to gastrointestinal reactions and vomiting.
There are also some situations where vomiting is not related to the disease, such as vomiting when a child cries heavily, or vomiting due to motion sickness or overeating. However, these situations can be easily identified and generally do not require examination and treatment.
What should I do if I have a fever after vomiting
1. The main route of transmission for viral gastroenteritis is fecal oral transmission, and a small portion may also be transmitted by droplets. The principle of prevention is to do a good job of cleaning, especially for sick children. The amount of virus in excrement is the most alarming, followed by saliva. Therefore, when taking care of excrement, it is necessary to handle it properly. After changing diapers, hands must be thoroughly washed clean.
2. Regarding the care of viral gastroenteritis, for babies under 1 year old, it is recommended to stop drinking formula milk first and switch to feeding small amounts of electrolyzed water multiple times for 8 hours. As for babies who drink breast milk, they can continue to be fed breast milk in small amounts for 8 hours. If they do not vomit after 8 hours, the milk output can gradually return to normal.
3. In addition, children who eat side dishes can also start eating lighter foods at this time. For children over 1 year old, if they vomit too much, they should first fast and avoid drinking water for 3-4 hours. After resting, they should drink water in small amounts multiple times. Letting children sleep is a good way to rest.
4. If you haven't vomited for 4 hours, you can start drinking water. If there is no vomiting for 8 hours, you can start eating some light food and continue for 2 to 3 days before returning to a normal diet.
Why does vomiting cause fever? This article provides a detailed analysis of this issue. Generally speaking, when a baby experiences acute inflammation, catching a cold, and indigestion in the gastrointestinal tract, it often leads to fever due to vomiting. At this point, it is important to observe the baby's mental state. Some babies may still be in good spirits after vomiting, while others may report falling asleep due to fever. In this case, immediate medical attention should be sought, and if necessary, intravenous treatment should be administered.
