Sudden high fever in an adult without symptoms

When an adult develops a high temperature without symptoms, it is always a cause for concern, because temperature, as one of the body’s reactions, does not occur out of nowhere. However, the absence of any symptoms is scary because it is impossible to immediately determine the cause of this condition.

The optimal temperature indicator for normally occurring processes in the human body is 36.6°C. However, there are times when the temperature becomes elevated for no reason.

On the one hand, for some people this is the norm: there are people for whom it is always 36, and there are those for whom it is normal - 37.4°C. On the other hand, if a person usually has a normal temperature of 36.6°C, then a high temperature without symptoms in an adult means some kind of disorder.

Why does elevated temperature occur?

In all other situations, an increase in body temperature above normal indicates that the body is trying to fight something. In most cases, these are foreign agents in the body - bacteria, viruses, protozoa, or a consequence of physical impact on the body (burn, frostbite, foreign body). At elevated temperatures, the existence of agents in the body becomes difficult; infections, for example, die at a temperature of about 38 C.

All fevers are divided into three groups:

1. Low-grade fever, in which the temperature rises from 37 to 38 degrees;
2. Febrile fever - temperature rises from 38 to 39 degrees;
3. Hectic fever is an increase in temperature from 40 degrees and above.

But any organism, like a mechanism, is not perfect and can malfunction. In the case of fever, we can observe this when the body, due to the individual characteristics of the immune system, reacts too violently to various infections, and the temperature rises too high, for most people it is 38.5 C.

How to overcome low-grade fever?

Eliminating low-grade fever is impossible without identifying its problem. An idiopathic increase in temperature is noted, but therapeutic effects on this are impossible.

Before generally drawing conclusions about the presence of low-grade fever, it is necessary to diagnose it. Not every increase in temperature to 37-37.5 °C is subfebrile, because it has already been reported that the temperature can increase by 0.5-1 °C in the late afternoon, depending on hormonal emissions and physical activity, and the psycho-emotional state.

The conclusion about low-grade fever is made based on an analysis of the temperature curve, which is usually constructed under the guidance of the attending physician or at least according to his recommendations, including:

If a conclusion is made about low-grade fever, the patient is shown profile and laboratory diagnostics, which begins in the therapist’s office. In search of an answer to the cause of low-grade fever, the patient is often forced to visit the following specialists:

The diagnostics prescribed to determine the causes of low-grade fever are:

Identification of deviations based on the results of any of the diagnostic methods performed becomes a reason for prescribing specific treatment.

Temperature is one of the most important indicators of health, helping to understand the relationship between the heat generated and the heat exchange occurring between organs and their tissues, on the one hand, and the external environment, on the other. Oddly enough, its indicators are not the same for everyone and depend on the following factors:

Causes of high fever in adults without symptoms

An increase in temperature or fever is observed in almost all acute infectious diseases, as well as during exacerbation of certain chronic diseases. And in the absence of catarrhal symptoms, doctors can determine the cause of the patient’s high body temperature by isolating the pathogen either directly from the local source of infection or from the blood.

It is much more difficult to determine the cause of a temperature without signs of a cold if the disease arose as a result of exposure to opportunistic microbes (bacteria, fungi, mycoplasma) on the body - against the background of a decrease in general or local immunity. Then it is necessary to conduct a detailed laboratory study of not only blood, but also urine, bile, sputum and mucus.

Causes of fever without symptoms may be associated with the following diseases:

1. Endocrine diseases, for example, thyrotoxicosis;
2. Systemic inflammation: Crohn's disease, rheumatism, polyarthritis, periarthritis nodosa, etc.;
3. Oncological diseases: tumors of the stomach, liver, kidneys, bronchi or lungs, lymphoma, leukemia;
4. Diseases of fungal, parasitic or viral etiology: syphilis, toxoplasmosis, candidiasis, malaria;
5. Infectious diseases: HIV infection, Lyme disease, relapsing and typhus, tuberculosis;
6. Inflammatory diseases of bacterial origin: sepsis, inflammation of the uterine appendages, prostatitis, meningitis, sinusitis, tonsillitis, pneumonia, endocarditis, etc.

In all situations, an increase in temperature without signs of a cold indicates that the body is trying to fight something. For example, the so-called low-grade fever is often accompanied by anemia - a low level of hemoglobin in the blood.

Is it necessary to lower the temperature?

It is generally accepted that an increase in temperature is a favorable factor, indicating that the body is resisting destructive influences. If the thermometer reading reaches 38.5 °C, there is no need to panic.

If its growth is observed, then it is worth bringing down the temperature using antipyretic medications - Paracetamol, Aspirin... you can also use NSAIDs - Ibuprofen, Nurofen. For children, children's Nurofen in the form of a sweet syrup is best suited, but Aspirin should not be given to a child.

At 42°C, irreversible changes occur in the cerebral cortex and death is possible. But this rarely happens.

Treatment of neurosis with sedatives

Calming pills help achieve relaxation, reduce nervousness, suppress fear, anxiety, and panic attacks. Their task is to improve the patient’s psycho-emotional state and ensure the effectiveness of psychotherapy. Sedatives are divided into sedatives of plant origin, bromide, barbiturates, and magnesium salts.

Natural medicines are considered the most effective:

1. Valerian tincture and tablets.
2. Products based on passionflower incarnate.
3. Tincture of peony or motherwort.
4. "Valoserdin", "Novopassit".
5. "Sedariston", "Fitosed".

Barbiturates inhibit the excited central nervous system and have anticonvulsant and hypnotic effects. The best drugs in this group: Phenobarbital, Hexobarbital, Barbamil.

Bromides are based on potassium or sodium salts, as well as hydrobromic acid. They have calming properties and activate neurological processes in the brain. Medicines are not intended for long-term use. The main means include: potassium or sodium bromide powder, the drug "Bromcamphor".

Sedatives will help you relax, suppress fear and anxiety

Temperature 37 without symptoms: possible causes

A runny nose, fever, and sore throat are all common symptoms of a common cold. But what to do if the temperature is 37 without symptoms? For what reasons does this occur and how to deal with it, let's figure it out.

Causes of fever without visible symptoms:

1. Onset of pregnancy (in women);
2. Weakening of the immune system;
3. The presence of any sluggish infection in the body;
4. Pre-cold condition;
5. Depletion of human energy reserves;
6. General fatigue, depression or post-stress state;
7. Sexually transmitted diseases (syphilis, AIDS, etc.)

Basically, a temperature of 37 without symptoms in an adult is due to the fact that there is some reason that caused such a condition, but it has not completely overcome the person’s defenses.

Temperature 38 without symptoms: possible causes

A temperature of 38 without symptoms can occur quite often. And the reasons for this temperature are not always the same. This temperature may signal that lacunar or follicular tonsillitis is beginning (with catarrhal tonsillitis, the temperature rises slightly).

If a temperature above 38 degrees without symptoms lasts for 3 or more days, then this may be a manifestation of:

1. Rheumatism;
2. Heart attack;
3. Inflammation of the kidneys (characterized by severe stabbing pain in the lower back);
4. Vegetative-vascular dystonia, accompanied by surges in blood pressure;
5. Pneumonia.

The most unpleasant syndrome is the persistence of an elevated temperature for several weeks and even months. This is most likely:

1. A sign of tumor development in the body;
2. Serious endocrine disorders;
3. Leukemia;
4. Diffuse changes in the liver or lungs.

The only thing that all these cases have in common is that in any case, the increase in temperature is due to the body’s resistance, which means that the immune system is fighting.

Treatment of neuroses with antidepressants

Diagnosed depression requires proper treatment with potent medications. Unlike simple sedatives that have a short-term sedative effect, the goal of antidepressants is to completely neutralize the syndrome. The proper effect is achieved 7-14 days after the start of treatment.

In medical practice they use:

• tricyclic drugs: Melipramine, Amitriptyline, Anafranil, Azafen, Opipramol. They have a good antidepressant effect. A positive result is observed after 1-2 weeks from the start of therapy. Restrictions for use - age 40 years and older, due to numerous side effects that have a negative effect on the blood vessels and heart;
• four-cyclic drugs: Tetrindol, Incazan, Pyrazidol. They have a less pronounced effect on the central nervous system, compared to antidepressants of the first group, but are safe for the body and have a limited number of undesirable effects. They can be taken by patients regardless of age;
• serotonin reverse synthesis inhibitors: Paxil, Fluoxetine. In terms of therapeutic effects, they are comparable to drugs of the tricyclic group, but have a slight toxic effect. The required result from taking medications is achieved only 3 weeks after the start of therapy.

All drugs for depression have a stimulating or calming effect and are prescribed by a doctor taking into account the symptoms of neurosis. For patients suffering from excessive excitability, drugs that have a stimulating effect on the central nervous system (“Melipramine”), which are used for inhibited conditions, are contraindicated.

Melipramine is contraindicated in patients suffering from excessive excitability

Temperature 39 without symptoms: possible causes

If a temperature of 39 without symptoms occurs in an adult not for the first time, then this is a clear sign of a pathological decrease in immunity and the development of a chronic inflammatory process. The phenomenon may be accompanied by loss of consciousness, febrile convulsions, difficulty breathing, or a further increase in consciousness. In this case, you must definitely contact a medical institution.

A high body temperature of 39-39.5° without obvious symptoms may be a signal of the following diseases:

1. ARVI;
2. The presence of a tumor process;
3. Development of catarrhal tonsillitis;
4. Manifestation of an allergic reaction;
5. Chronic pyelonephritis;
6. Manifestation of hypothalamic syndrome;
7. The presence of viral endocarditis;
8. The appearance of meningococcal infection.

What to do?

First of all, see your GP. Very often we are simply unable to notice certain symptoms, but a doctor can easily identify them and be able to diagnose the disease. It is also necessary to take tests; they will help identify many diseases that do not manifest themselves externally. Sometimes your doctor may order a sputum, urine or blood culture, x-ray or ultrasound.

It is not recommended to abuse antipyretics. By relieving a symptom, you can postpone the examination for a long time and start the disease, which, of course, is harmful to your health.

If the temperature is very high, it is worth calling an ambulance so that doctors can provide emergency care and resolve the issue of hospitalization. In any case, high temperature is the body’s “cry” for help, and you should pay attention to it.

At least I need to write something. So to speak, to indicate that sometimes I am still here. And just for myself... The boys are growing up. Ilya had his first competitions, he lost them, I really didn’t like the behavior of the coach - he didn’t come at all once, didn’t support me in any way, didn’t guide him in any way... I don’t consider him at all to blame for my son’s loss, it’s just kind of insulting, he’s the smallest in the team, for the first time on totami, but oh well. I'm proud of Ilya. He wasn’t afraid, he came out, did everything right, but in the second round he got kicked in the solar plexus and the fight was stopped. Although it was possible to continue. Ilya was upset, but did not run away with the tots, he performed everything, all the rituals, and came to me, bursting into tears in my arms. I think he did everything he could for the first time. Now they are preparing a team to take the belts, I don’t know yet whether Ilya will take it. But he does 20 clean push-ups with his fists, and another 10 with difficulty. On palms from the floor up to 40 times. The coach likes it, and he constantly forces him to do push-ups as punishment and more. He learns kata, remembers, but the movements are imprecise. Therefore, I would not be lucky enough to go to certification yet, but in any case, what will the coach say. We will try more, we will have more experience and less fear. Everything works out well in his studies, he reads, writes, writes words by ear, does math, solves problems, he has enough brains to do everything. And for nasty things too. I see that vulgar things have entered society. Sometimes he says and does whatever he wants. Artemy generally doesn’t understand what’s what, which makes it sound even more vulgar from him... The topic doesn’t know anything, doesn’t have all the letters, doesn’t want puzzles, loves to draw, loves to sing, Ilya, by the way, has also become interested, loves to listen to fairy tales and get mad and talk nonsense. I teach him to speak correctly, he moves his tongue forward all the time while speaking, the sounds fly. But during classes everything speaks perfectly. He is also in a hurry to say and swallows endings. Well, we teach poetry how to pronounce sounds correctly. I think we'll fix it. I still go to a psychologist, my condition is much better, I don’t take any neurological pills, only psychotherapy. Honestly, I’m scared... To realize that for some time now you have been a mentally ill person... In general, this disease has devastated me, and I am very afraid of such a state, it’s worse than you can imagine, when even children are unable to tear you away from the sofa... It was horror, and I don't want to experience it anymore. It was necessary to go still at the stage of thermoneurosis, and not inject myself with all these drugs that aggravated the course... I had felt everything for a long time, and I told my husband, and since October this feeling of a trait was there all the time, I thought that death was close. There were signs of this everywhere, a feeling of imminent inevitability. Then I still had to run to a psychologist. Besides everything else, I became seriously interested in meditation practices, and I believe that only thanks to them I was able to overcome the acute stage within two months. Of course, I don’t devalue the work of a psychologist. She is from God. But through meditation I relieved the exacerbations. Further, if you don’t believe in these practices, don’t read. I’m not crazy at all, but when I started practicing, every single chakra and my entire spinal column hurt. Laugh if you want, consider me a fool if you want, but after that I began to come to life. At first I didn’t attach any importance to this pain, because during the period of neurosis, everything hurt me. My heart was pounding, my arms and legs were numb, my back was stiff, shortness of breath was constant, for two weeks I couldn’t look at food and exhaustion set in, I forced myself to eat, but the food stood like a stake, etc... Here’s a picture... I couldn’t sleep at night... Then I arrived Dad cleared my mind, and I began to come to my senses. He also experienced this, only without psychologists. He was dragged to hospitals and was almost treated to death. In general, patients with VSD are walking money. They are ready to pay everyone, no matter how much, just to be cured, and everyone treats them, but the problem is that this can only be treated with psychotherapy. No matter how many tranquilizers you eat, you will return, and you will return to this point until the internal conflict ceases to be burning and relevant. There is no VSD. There are neuroses and psychological pressures, and everything can be treated; for the first such diagnosis, a psychologist is needed. Until I needed a psychotherapist or psychiatrist. And that's it. I'm starting to live. After many years of absence of me as a person in this life, I begin to live. To wish, to dream, to feel...
