What should I do if my one-year-old baby has a body temperature of 38.3°C?

Generally, a body temperature of 38.3°C in a one-year-old baby may be caused by factors such as the common cold, food stagnation (indigestion), or tonsillitis. Patients should seek symptomatic treatment under the guidance of a doctor. Specific analyses are as follows:

1. Common Cold

During a cold, the immune system releases chemical substances called interleukins, which can cause an increase in body temperature, leading to fever, along with symptoms such as runny nose and cough. Under medical guidance, medications such as pediatric paracetamol-phenylpropanolamine granules, pediatric cold granules, or An'erning granules may be administered for treatment.

2. Food Stagnation (Indigestion)

Food accumulated in the gastrointestinal tract may ferment and produce large amounts of gas. These residues and gases can irritate surrounding tissues, potentially causing local infection, accompanied by symptoms such as fever, abdominal pain, and diarrhea. Under medical supervision, treatments may include lactasin granules or pediatric lactasin tablets.

3. Tonsillitis

Tonsils, part of the immune system located in the oropharynx, help defend against bacterial and viral invasion. However, when infected, increased activity of immune cells leads to the release of inflammatory mediators, triggering immune and febrile responses. Under a doctor's guidance, medications such as cefixime dispersible tablets or ribavirin granules may be prescribed for treatment.

In addition, other possible causes include pneumonia, infantile emergency rash (roseola), rotavirus infection, etc. It is recommended to promptly consult a healthcare professional and undergo further examination and treatment.
