Baby has fever and diarrhea

When your baby has a fever and is also suffering from diarrhea, the most important thing is to reduce the temperature. You cannot let your baby's fever symptoms get worse, otherwise it will cause damage to their brain tissue. At this time, you can try some physical cooling methods to improve their fever. If necessary, you can use some antipyretic drugs.

Fever refers to a body temperature that exceeds the upper limit of the normal range and is a very common symptom in children. The normal axillary temperature of children is 36℃ ~ 37℃ (the temperature measured by rectal thermometer is about 0.3℃ higher than that measured by oral thermometer, and the temperature measured by oral thermometer is about 0.4℃ higher than that measured by axillary thermometer). If the axillary temperature exceeds 37.4℃, it can be considered as fever.

In most cases, fever is a protective response of the body against invading pathogens and is a process in which the human body mobilizes the immune system to fight infection. An abnormal increase in body temperature is not necessarily proportional to the severity of the disease, but excessive fever or long-term fever can affect the body's various regulatory functions, thereby affecting the child's physical health. Therefore, for children confirmed to have a fever, the cause should be actively identified and treated accordingly.

A child's normal body temperature may fluctuate within a certain range due to factors such as gender, age, day and night and seasonal changes, diet, crying, temperature, and the thickness of clothing. A slight increase in body temperature does not necessarily have pathological significance. When a child's temperature rises, pay attention to the child's demeanor and behavior. A child with a body temperature of 38℃ and a dull look is more worthy of attention than a child with a body temperature of 40℃ but still naughty. Children with low resistance will most likely not have a fever even if they suffer from a serious illness.

2) Other system infections: intestinal infection, urinary system infection, central nervous system infection (encephalitis, meningitis), cardiovascular system infection (such as infective endocarditis, pericarditis), hepatobiliary system infection (such as hepatitis, cholangitis, liver abscess, etc.);

3) Systemic infections such as sepsis, tuberculosis, typhoid, paratyphoid, typhus, brucellosis, Epstein-Barr virus infection, cytomegalovirus infection, Lyme disease, leptospirosis, malaria, kala-azar, schistosomiasis and fungal infections;

4) Abscess or localized infection such as osteomyelitis, perinephric abscess, subphrenic abscess, appendiceal abscess, perianal abscess, etc.

(2) Non-infectious fever

1) Juvenile rheumatoid arthritis is the most common rheumatic disease. In recent years, as streptococcal infections have been promptly controlled, rheumatic fever has become less common. Other rheumatic diseases that cause fever include systemic lupus erythematosus, polyarteritis nodosa, Kawasaki disease, serum sickness, dermatomyositis, nodular nonsuppurative panniculitis, Wegener's malignant granulomatosis, and angioimmunoblastic lymphadenopathy.

2) Malignant tumors with tissue destruction or necrosis, with leukemia being the most common, and others including malignant lymphoma (including Hodgkin's and non-Hodgkin's lymphoma), neuroblastoma, malignant histiocytosis, Langerhans' histiocytosis and Ewing's sarcoma; large-area burns, after major surgery, internal bleeding absorption process, vascular embolism, etc.

3) Excessive heat production or reduced heat dissipation Excessive heat production is seen in hyperthyroidism, status epilepticus, and adrenal hyperfunction; reduced heat dissipation is seen in generalized dermatitis, massive water loss, blood loss, heat stroke, congenital ectodermal dysplasia, and excessive wrapping of newborns.
