High body temperature (fever, fever) is a temporary increase in body temperature and immune response in response to some disease.
child has a fever when his temperature is above par, or one of these levels:
- 38 ° C - measured rectally;
- 37,5 ° C - izmeryaetsyaoralno;
- 37,2 ° C - measured axillary.
An adult probably fever - above 37,2-37,5 ° C, depending on the time of day.
Normal body temperature can change on any given day.It usually increases in the evening.
Other factors that can affect the body temperature:
- the second part of the woman's menstrual cycle, the temperature may rise by 1 degree or more;
- physical activity, strong emotion, eating, heavy clothing, medications, high room air temperature and high humidity.
High body temperature is an important part of protecting the body fight infections.Most bacteria and viruses that cause infections in people thrive at high temperatures.Many babies and children have a high temperature at
Brain damage from elevated body temperature usually does not happen if the high body temperature is over 42 ° C, and will not go above.Untreated fevers caused by infection, rarely pass 40 ° C, unless the child is not stripped or not much hot place.
Febrile seizures occur in some children.However, most febrile seizures (about febrile convulsions may be involved in the event of seizures at body temperature above 38 ° C in children under six years of age who have not previously suffered seizures), which quickly ended, does not mean that the child is sufferingepilepsy.
Unexplained fevers that continue for days or weeks are called "fever of unknown origin of the body."
temperature Almost any infection can cause fever.Some common infections:
- pneumonia, bone infections (osteomyelitis), appendicitis, tuberculosis, infections or skin cellulitis (acute diffuse purulent inflammation of the subcutaneous fat; cosmetic problems caused by structural changes in the subcutaneous fat layer) and meningitis (inflammation of the brain membranesbrain and spinal cord, and in clinical practice - pial inflammation, infection membranes covering the brain);
- respiratory infection - such as cold or flu, sore throats, bronchitis, ear infections, sinus infections, infectious mononucleosis (acute viral disease characterized by fever, lesions of the pharynx, liver, spleen and peculiar changes of the blood, pain in the throat and an increase inlymph nodes are also characterized by certain changes in the blood tests, caused by human herpes virus type IV or Epstein-Barr virus);
- urinary tract infection;
- viral gastroenteritis;
- bacterial gastroenteritis.
Children can have a low-grade temperature 1 or 2 days after some immunizations.
Dental pain can cause a slight rise in temperature in the child, but not higher than +38 ° C.Autoimmune and inflammatory disorders can also cause fever.Here are some examples:
- arthritis or connective tissue diseases - such as rheumatoid arthritis and systemic lupus erythematosus;
- ulcerative colitis (ulcerative colitis or ulcerative colitis - immune nature of chronic inflammatory relapsing disease of the colon mucosa, resulting from the interaction between genetic factors and environmental factors, characterized by exacerbations and diffuse inflammation of the mucous membrane of the large department intestine - rectum and colon. colon UC ill people of all ages, often - 20-40 years, 60-70 years, men and women suffer equally often);
- Crohn's disease (a chronic nonspecific granulomatous inflammation of the gastrointestinal tract, which can affect all of its divisions, from the mouth and ending with the rectum, with a primary lesion of the terminal segment of the ileum and ileokolitom in 50% of cases, it affects all levels of the digestive tube,inflammation, lymphadenitis, ulceration and scarring of the bowel wall);
- vasculitis (or vasculitis, arteritis -. generalizing the generic name of a group of diseases in which the painful process involved several organs or tissues in the basis of these diseases is inflammation of the blood vessel wall) or periarteritis nodosa (leading to progressive organ failure, inflammatorythe defeat of the arterial wall vessels of small and medium caliber with the formation of microaneurysms).
first symptom of cancer can be a high body temperature.This is especially true for: Hodgkin's disease (or Hodgkin's lymphoma, Hodgkin disease - malignant disease that affects organs of the lymphatic system, mainly the lymph nodes, as well as - the spleen, thymus, adenoids, tonsils A / u are part of the lymphatic system.they are interconnected lymphatic vessels, which circulates a special liquid - a lymph; Hodgkin's disease, any group l / y may be involved in the process in the advanced stages can affect the internal organs - liver, lungs, and bones and bone) as well.and - non-Hodgkin's lymphoma (or lymphoma Burkitt - very high degree of malignancy that develops from B-lymphocytes and has a tendency to spread beyond the lymphatic system - in the bone marrow, blood and cerebrospinal fluid develops as a result of cytopathic effects on lymphoid cells Epstein-Barr virus.without treatment progresses rapidly and leads to death), and leukemia.
Other possible causes of elevated body temperature:
- blood clots or thrombosis;
- medicines - such as some antibiotics, antihistamines, and anticonvulsants.
Treatment and care home with fever and high temperature
simple cold or viral infection can sometimes cause high body temperature (38,9-40 ° C).This does not necessarily mean that the patient is an adult or a child with serious health problems.Some serious infections may not cause an increase in body temperature, or even cause a very low body temperature, especially in infants.
