Why does my baby always have a low-grade fever?

In real life, a low fever in babies is a very common physical illness, and there are many reasons for a baby's low fever. Generally, it may be caused by a disease or infection. Usually, a baby's viral infection is also prone to low fever. You can do a detailed examination and treatment, or you can use physical methods to treat it, and observe the baby's condition in time.

Why does my baby always have a low-grade fever?

1. Physical reasons: The baby's metabolism is fast, and body temperature fluctuations within 1°C are considered normal.

2. Weather reasons: It is related to the weather. The baby’s water intake is insufficient and sweating is less, which leads to higher body temperature. When the weather turns cooler, your baby's body temperature will return to normal.

3. Dietary factors: The baby has indigestion and food accumulation. He is likely to have symptoms such as low fever, loss of appetite, and vomiting. At this time, you may need to make dietary adjustments or use digestive medications to treat it.

4. Infectious low fever: After the baby becomes ill, the disease will recur due to insufficient treatment, and there will also be intermittent low fever.

5. Low fever after infection: After the baby suffers from infectious diseases such as measles, diphtheria, whooping cough, bacillary dysentery, and Japanese encephalitis, the function of regulating body temperature has not fully recovered, resulting in persistent low fever.

6. Chronic infectious low fever: such as tuberculosis, chronic tonsillitis, otitis media, sinusitis, urinary tract infection, etc., which cause the baby to have continuous low fever.

7. Non-infectious low fever: If the baby has blood diseases, endocrine and immune system diseases, low fever may occur.

What to do if your baby has a low-grade fever

If the baby's body temperature remains between 37.5℃-38℃ for more than 2 weeks, it can be considered as a low-grade fever that will not go away. Long-term low-grade fever will affect the body's regulatory function, reduce digestive juices, reduce digestive enzyme activity, and decrease absorption function, resulting in negative nitrogen balance and increased protein decomposition in the body. At this time, children are prone to adverse conditions such as weakness, weight loss, and low immune function. Therefore, if your baby has a long-term low fever, you must find out the root cause and treat it in time. Once your baby has a persistent low fever, you as a parent need to be vigilant.

It is recommended that parents should record their children's body temperature in detail before taking them to the doctor. Generally, the temperature should be recorded every 4-6 hours. It is best to measure it once in the morning and before getting up at noon and before going to bed, and continue to record it for more than 1 week.

In addition, parents should also observe other symptoms that accompany the baby's low-grade fever, such as changes in appetite, fatigue, night sweats, facial flushing, hot hands and feet, cough, frequent urination, painful urination, joint pain, constipation, weakness, etc. Children with low fever should be urged to pay more attention to rest, create a quiet environment for them, and maintain air circulation. Babies with low fever should drink more water and eat a light diet, which should mainly consist of nutritious protein and vitamin foods, and avoid greasy foods. The following are treatment plans for different types of low-grade fever for parents' reference.
