A high fever of 42 degrees has a certain damage to the body’s metabolic balance, cardiovascular function, nervous system function, digestive function, immune function and so on.
1. Metabolic balance: high fever increases all kinds of nutrient metabolism, oxygen consumption also increases greatly, and basal metabolism increases, which may lead to diarrhea, dehydration, and further metabolic disorders.
2. Cardiovascular function: with the rise in body temperature, the heart rate is relatively faster, so the cardiovascular burden increases.
3. Nervous system function: high fever can make the cerebral cortex over-excited (irritability, febrile convulsions, etc.) or highly inhibited (banter, lethargy, coma, etc.), especially in infants.
4. Digestive function: high fever reduces the secretion of digestive juices, digestive enzymes, gastrointestinal peristalsis, so there is a loss of appetite, bloating, constipation and other symptoms.
5. Immune system function: persistent fever can reduce the body’s ability to defend itself against infections.
If high fever occurs, it is recommended to go to the hospital in time, and be treated by the doctor after a clear diagnosis, so as not to delay the condition.
