Probably, more than once, it was that nobody from this, for example, after the night you slept, you woke up and felt something wrong: the head was hurting,and the temperature. This is most likely the first signs of acute respiratory disease. But in some cases, you can make a mistake with the diagnosis, because the diseases that are accompanied by headache and low-grade temperature( 37-380C) are more than enough. Consider the main causes of such a combination of pathological symptoms.
A bit about the main
To begin with, you need to understand some medical terms. The subfribal temperature is an increase in body temperature not higher than 380C.Although such a fever does not completely remove a person from the "working condition", it significantly impedes the performance of everyday tasks, especially when accompanied by headache simultaneously.
At a stable temperature of the human body, the system of thermoregulation, the center of which is located in the hypothalamus of the brain, corresponds. Violation of the thermoregulation center with the shift in the direction of heat formation can occur under the influence of several factors:
- antigens of various pathological microorganisms( viruses, protozoa, bacteria, fungi, parasites);
- foreign antigens of non-microbial origin;
- circulating immune complexes in the blood;
- sensitized T lymphocytes( cells of the immune system);
- cell breakdown products;
- endotoxins of various origins;
- neurological and endocrinological mechanisms of the hypothalamic disorder;
- products for the metabolism of some tumor cells.
Increase in temperature as a protective reaction was made throughout the human evolution stage, and the main task of the fever is to create an obstacle to the reproduction of pathological microorganisms and to accelerate the development of protective antibodies by the immune system.
But in spite of the protective role, the fever also has negative sides, which affects our well-being when the temperature rises. With an increase in temperature, all metabolic processes in the body are accelerated, the metabolism is mainly due to the type of catabolism( the disintegration of the finished substances, proteins, fats, carbohydrates with the release of energy), which leads to loss of mass, muscle tissue and general weakness, intoxication of the bodyproducts of exchange, headache. At the same time, the frequency of heartbeat is more frequent, seizures may occur, which is often the case with young children.
therefore no need to tolerate temperature rise. Today there are effective drugs that not only help to cope with fever and bad health, but also to destroy any microorganisms that have led to a violation of the system of thermoregulation and headache.

Infectious causes of
It is through the penetration of pathogens in the body and the development of most fever with headache, and this may be likeacute and short-term increase in temperature, for example, in a flu, and chronic fever in libido-current chronic infections, for example, tuberculosis, HIV infection, brucellosis, toxocarosis, etc.
Acute Respiratory Viral Infections and Influenza
For this reason, a patient with headache and a temperature of 37C has reported more than half of all cases, especially in the autumn-winter season and the epidemic outbreak of acute respiratory viral infections.
The etiologic factors most often act as:
- influenza virus and parainfluenza;
- respiratory sentimental virus;
- rhinovirus infection;
- adenovirus infection;
- herpesviruses( Epstein-Barr, etc.).
Often, lesions caused by these pathogens are accompanied, in addition to fever and headache, with other symptoms. Among them, the most common catarrhal phenomena are runny nose, cough, sore throat, nasal congestion, eye redness and lacrimation, an increase and pain in regional lymph nodes. The peculiarity of headache in influenza is its diffuse, disruptive nature, the pain extends to the eyeballs, and any movement in the eyes becomes painful.
As a rule, temperature and headache appear at the very beginning of the disease and within 3 days completely pass, if the indicated signs last longer, then you need to think about possible bacterial complications of SARS.
Other acute infectious diseases
Any acute infectious diseases may be accompanied by subfebrilitis and headache. After respiratory infections the second place is given by intestinal toxicosis. These can be pathological intestinal strains, dysentery, typhoid fever, intestinal infections caused by ECHO and Coxa virus, amebiasis, helminth infestations, salmonella, pathological types of staphylococci, etc.
But the onset of the clinical picture of intestinal infections is gastrointestinal disturbances, pain instomach, nausea, vomiting, which greatly simplifies the diagnosis. But the first few hours after infection, the only symptoms can be only high fever and headache due to intoxication.
Ear, throat and nose disorders are often a cause of subfebrile and headache. It can be both chronic and acute lesions - tonsillitis, pharyngitis, sinusitis, adenoids, nasopharyngitis, otitis, etc. Most often accompanied by headache, sinusitis, the pain is localized mainly in the frontal area and has a pulsating nature.
Inflammatory neurological diseases
A very serious pathology that may be accompanied by headache and fever is meningitis or encephalitis. The peculiarity of headache is its very intense nature, it does not pass under the action of usual analgesic drugs, it has a common and disruptive character, accompanied by nausea and vomiting. The temperature, as a rule, rises to febrile digits( over 380C), but subfebrile can also be observed.
These are very dangerous diseases that without timely treatment can even lead to death due to cerebral edema as a result of increased intracranial pressure. Along with the indicated symptoms can be observed and other signs - hemorrhagic rash, rigidity of the occipital muscles, focal and cerebral neurological symptoms.
Urinary system infections
Causes of headache and fever may be acute or chronic inflammatory diseases of the genitourinary system: cystitis, pyelonephritis, glomerulonephritis, prostatitis, orchitis in men, adnexitis, endometritis in women.
To suspect this group of pathology can also be a violation of urination, pathological secretions from the genital organs, pain in the lower abdomen and perineum.
Causes of non-infectious nature of
Non-infectious diseases can be the cause of headache with a rise in temperature. Let's consider the most frequent among them.
Acute Surgical Pathology
Among these pathologies, the cause of fever and headache may be:
- acute appendicitis;
- intestinal obstruction;
- acute cholecystitis and pancreatitis;
- abscesses of different localization;
- phlegmons and boils;
- thrombosis of the vessels of the lower extremities;
- breakthrough gastric ulcer.
Headache, subfebrile, with these diseases go into the background, the main symptoms are abdominal pain and other signs of damage to one or another body. But at the very beginning of the disease can only be cephalalgia and subfebrile( especially characteristic of abscesses of different localization).
Solar or Heat Stroke
It is easy to diagnose this condition. The main point is the indication of prolonged exposure to sunlight or thermal radiation, for example, holding a few hours in the sun on the beach, working in closed soiling rooms, etc. Except for headache and fever, there is thirst( dehydration), sunburn, general fatigue.
In this case, poisoning by various chemical compounds is meant. Penetrate poisons through the skin, respiratory tract, gastrointestinal tract. In addition to the pain of the head and temperature, there are various pathological symptoms depending on the type of poison and the method of its penetration into the body. Gastrointestinal manifestations are very common( diarrhea, vomiting, nausea, abdominal pain), neurological manifestations, disturbances in consciousness, changes in the color of the mucous membranes and skin, metallic taste in the mouth.

If symptoms persist for a long time
It happens that a person suffers from subfebrilitis and headache for more than one week and even not one month. As a rule, various medical reviews initially do not give an answer about the causes of this condition and the person diagnosis a fever of obscure or central genesis. Indeed, there are conditions that are not accompanied by any pathological changes, but the temperature remains elevated even for many years. This is considered the norm for some people( these are only one).In other cases, under this diagnosis, there are very serious illnesses.
In case of prolonged fever, tuberculosis( the most common cause) must be ruled out in the first place. It's not so easy to do, because in each case the patient does not isolate the bacteria from the outside. Suspect a TB infection can be also on instructions for chronic cough, slimming, increased sweating, especially at night, contact with an infected person, allocation of blood with sputum, general fatigue, lack of appetite.
Mandatory X-ray of the chest, Mantoux test, sputum research for the presence of bacillus Koha, and, if necessary, biopsy of the suspected area of the pulmonary tissue.
Laying chronic infections
These are infectious diseases that do not cause an active immune response of the human body, which contributes to their long-term persistence. Such infections include HIV / AIDS, infectious endocarditis, rheumatic fever, infectious mononucleosis, herpesvirus infection, Epstein-Barr virus, chronic pyelonephritis, chronic diseases of ENT organs, brucellosis, toxocarosis, toxoplasmosis.
Often the cause of prolonged subfebrile and headache are cancer. Novellation of any localization may cause fever and headache. Tumor cells isolate substances that act as pyrogens - act on the center of thermoregulation, which causes a rise in temperature.
The cause of headache and fever may be thyroid disease, in particular thyrotoxicosis( increased thyroid function with hyperproduction of hormones).Along with the indicated symptoms there is tachycardia, sweating, tremor of the body, cardiac arrhythmias, diarrhea, abdominal pain, nervousness, emotional lability, irritability, fatigue.
As already mentioned, there are people for whom low-grade temperature is an individual norm. But, if it is accompanied by a constant headache, then it's likely to be a case of some not yet diagnosed illness.
Psycho-vegetative causes of
In some people, headaches and high fever may be part of the syndrome of vegetative-vascular dystonia( thermoneurosis).
Hyperthermia of the central genesis of
This type of elevated temperature develops as a result of pathological processes in the brain that affect the hypothalamus and the center of thermoregulation. These can be the consequences of a craniocerebral trauma, a transmitted infectious disease of the brain and its membranes, parasitic lesions of the brain tissue, for example, echinococcosis, brain tumors.
How to help yourself?
If this happened, and you were caught up with headaches, low-grade temperature, then you need to know how to improve your well-being.
Important! If, in addition to headache and temperature 370C, there are other pathological symptoms that cause you anxiety( abdominal pain, vomiting, nausea, severe drowsiness, seizures, hemorrhagic rash, etc.), then in no case can self-medication be involved. It is necessary to apply immediately to specialized medical care in order not to miss a life-threatening pathology.
The first thing you need is bed rest. It is also necessary to provide a rational drinking regime - it is necessary to drink up to 2-3 liters of fluid per day to get rid of intoxication( warm tea, compote, fruit juice, fruit juices).To get rid of headache and temperature you can use the same drugs from the group of nonsteroidal anti-inflammatory. To this end, you can take paracetamol 200-500 mg, aspirin 240 mg, ibuprofen 400 mg. Once your well-being has been established, go to the clinic for examination and appointment of adequate treatment.
Many people are wrong with prescribing antibiotics for their first symptoms of acute respiratory infections, and absolutely do not adhere to the rules of antibacterial drugs. With such actions, many patients only harm their health. Antibiotics should be prescribed only by the physician after examination of the patient, taking into account all the nuances, since the choice of drugs and their dose - it is not easy.
