Why does my baby have repeated fever? Let you understand the full reasons

It is common for children to have fever symptoms occasionally, and there will be no serious problems. However, if the fever symptoms last for a long time and the cause is unknown, parents need to pay attention, because this may be caused by some serious illness.

1. Non-infectious fever

It is not caused by various infectious diseases. It is caused by sterile substances or various inflammations acting on the body temperature regulation center, dysfunction of the body temperature center, or excessive heat production and reduced heat dissipation due to various reasons, resulting in a temperature rise exceeding the normal range.

2. Fever of unknown cause

The broad concept of fever of unknown origin refers to all people with fever of unknown origin. However, the narrow concept of fever is still used clinically, that is, fever of unknown cause. Fever persists for more than 3 weeks, with body temperature above 38.5℃, and a clear diagnosis cannot be made after detailed medical history, physical examination and routine laboratory tests.

3. Central fever

Central fever can also cause the baby to have repeated fevers. Central fever refers to fever caused by abnormalities in the body temperature regulation center due to lesions in the central nervous system. Before diagnosing it, fever caused by systemic or local inflammation and other causes of fever should be strictly excluded. Intracranial diseases accompanied by fever are mostly critical cases, and the fever in most patients is caused by intracranial inflammation, lung infection, and urinary tract infection. For those with unexplained moderate fever whose source or cause of infection cannot be found at the moment, it should not be easily assumed to be central fever. Systemic or local infection causes should be repeatedly sought to exclude them, and attention should be paid to drug fever and other causes of fever.

What should my baby eat when he has a recurring fever?

1. Drink plenty of water

Babies with fever must dissipate heat by sweating, which results in the consumption of a large amount of water. Therefore, what children need to replenish most during a fever is water rather than food.

2. Eat liquid food

When a baby has a fever, his diet must be mainly liquid or semi-liquid food, such as milk rice soup, milk powder, millet porridge, fresh juice, mung bean soup, etc. Give your baby some fresh fruit and vegetable juice appropriately. If you accidentally overfeed your baby, you can massage your child's abdomen to promote digestion, or eat some foods that promote digestion, such as children's probiotics.
