Fever without temperature occurs after taking spicy food and alcohol, with severe stress and excitement, in women during PMS and menopause. The pathological causes of the symptom include VSD and hypertension, thyroid damage, CNS diseases. The examination includes a standard examination by a neurologist, instrumental methods (ECG, EchoCG, EEG, CT of the brain), laboratory tests. Treatment consists in the normalization of lifestyle and nutrition, the use of psychotherapeutic and physiotherapeutic techniques. Medications are prescribed after identifying the cause of the disorder. In case of tumor processes, surgical interventions are performed.
Causes of fever without temperature
The use of spicy and hot dishes is the most common cause of heat without temperature. The symptom occurs during a meal or immediately after a meal. First there is a feeling of warmth in the torso, then the heat spreads throughout the body. A person’s cheeks turn red, the skin becomes hot to the touch. Sometimes, when taking too spicy foods, general sweating is noted, droplets of sweat appear above the upper lip.
The feeling that there is a strong fever in the whole body happens after taking strong alcohol. When drinking alcohol, heat is felt spreading from the chest and abdomen to the extremities. The redness of the face, the shine of the eyes are noticeable. Sometimes alcohol consumption provokes redness not only of the face, but also of the neck and trunk. The warming effect does not last long: if a person goes out into the cold, chills develop quickly without temperature.
Fever at normal temperature is often caused by strong excitement, fear. It seems to a person that the whole body is burning, while the face turns red, the skin becomes very warm or hot. Sometimes, under stress, there is a tremor of the fingers, interruptions in the work of the heart. An unpleasant feeling of heat throughout the body persists until the person calms down. Such signs are more typical for emotionally labile young women, but can occur at any age.
Hormonal changes in women
Many cases of fever throughout the body as a component of PMS have been described. The symptom is associated with both disorders of vascular tone regulation caused by changes in hormone levels, and increased emotionality of women in this period. Fever without temperature is observed 1-2 days before the onset of menstrual bleeding. It can appear paroxysmally for 5-10 minutes or last for several hours.
Hot flashes throughout the body sometimes occur during menopause, but in this condition, heat is more often felt in the head and upper torso. Menopausal hot flashes are especially pronounced at night. Women wake up due to an unpleasant feeling of heat, excessive sweating and a feeling of lack of air. Symptoms are accompanied by headache, darkening of the eyes. The attacks are repeated several times a night, provoking insomnia.
Vegetative vascular dystonia
In case of violation of neuroregulation of vascular tone, heat attacks throughout the body without temperature are caused by the action of any predisposing factor: stress and fatigue, physical exertion, cyclic hormonal changes in the female body. Sometimes tides develop for no apparent reason. A person feels that the heat seems to spread from the depths of the body, the skin acquires a pink hue and becomes hot.
With vegetative-vascular paroxysms, fever is combined with polymorphic symptoms: dizziness, a feeling of sinking of the heart, tremor of the hands. As a rule, unmotivated anxiety appears. At the end of the attack, the feeling of warmth is replaced by chills, sometimes there is a cold sweat. The patient has an urge to urinate, during which a large volume of light urine is released.
The feeling of heat throughout the body is more characteristic of pseudoallergia. The sign is caused by a sharp release of histamine from cells when eating certain foods (strawberries, chocolate), medicines. In addition to heat without temperature, there is redness of the entire skin surface, severe itching. The clinical picture is complemented by breathing difficulties, paroxysmal headaches. Similar manifestations occur with true allergies.
The feeling of heat without an elevated temperature occurs with changes in blood pressure. The increase in blood pressure is accompanied by a feeling of warmth throughout the body, redness of the skin. The patient has difficulty breathing, it begins to seem to him that there is “less air” in the room. Well-being improves after taking pills that normalize blood pressure.
Diseases of the thyroid gland
The symptom is observed with increased hormonal activity of the organ. Thyroid hormones T3 and T4 stimulate the basic metabolism and increase energy production, so the feeling of gift accompanies a person constantly. Manifestations do not depend on indoor temperature and emotional factors. Patients complain that they are constantly hot, wear lighter clothes out of season, and cannot stay in stuffy rooms.
In addition to the heat throughout the body, the skin often turns red, but there is no excessive sweating. Inhibition of sweat gland activity is pathognomonic for thyroid hyperfunction. Symptoms are combined with exophthalmos, palpitations, irritability. The appearance of fever without temperature is a typical sign of thyrotoxic goiter, thyroid tumors, and the initial stage of thyroiditis.
The center of thermoregulation is located in the hypothalamus, respectively, with a brain lesion, a paroxysmal or constant feeling of heat is possible. The pathological sign is not related to external factors, does not depend on the ambient temperature. Usually, when the hypothalamus is damaged, fever is accompanied by general hyperthermia. This condition is typical for TBI, tumors of the pituitary-hypothalamic system.
When a fever appears in the whole body without a temperature, the patient turns to a therapist, who determines the alleged cause of the symptom, and then prescribes a referral to a narrow-profile specialist. The doctor is interested in how long ago the symptoms began, what, in the opinion of the patient, they are related to, whether any treatment was used at home. Diagnosis of the causes of malaise includes the following methods:
Instrumental research. To assess the work of the heart, an ECG and echocardiography are performed. To identify pathological changes in brain functions, a non-invasive EEG method is prescribed. X-ray methods (CT, scintigraphy) are indicated if a tumor process is suspected.
Laboratory methods. Standard diagnostics includes general and biochemical blood tests to exclude latent inflammatory or metabolic disorders occurring without temperature. Be sure to determine the level of thyroid hormones, adrenal cortex hormones, ACTH and TSH. In women, the indicators of estrogens, progesterone, FSH and LH are examined.
Neurological examination. The doctor determines the activity and symmetry of reflexes, checks the initial tone of the autonomic nervous system. Functional tests (orthostatic, pharmacological) are used to study the features of nervous regulation. If necessary, the examination is supplemented with a psychiatric examination.
Help before diagnosis
Most attacks of fever in the body without temperature are not associated with pathological factors. To stop them, non-drug methods are enough. Patients need to exclude from the diet too spicy and spicy dishes that cause hot flashes. The food should be warm, but not hot. The same applies to tea, coffee and other beverages. It is necessary to limit alcohol consumption as much as possible, especially strong — with an ethanol content of more than 20%.
In order not to provoke paroxysms of heat throughout the body, you should regularly ventilate the room, avoid stuffy rooms and gatherings of a large number of people. It is important to eliminate stressful situations at home and at work as much as possible. Doctors recommend to reduce the time of Internet surfing and watching TV shows. Frequent bouts of fever without an increase in temperature are a reason to consult a doctor, since they can be a sign of serious diseases.
The selection of medicines for fever in the whole body without temperature is carried out after determining the cause of the malaise. If hot flashes occur against the background of menopausal syndrome, gynecologists prescribe hormone replacement therapy. Treatment helps to normalize well-being, reduces the frequency of paroxysms of fever, eliminates other symptoms of menopause. In hypertension, rational hypotensive therapy is prescribed, taking into account the patient’s age and the severity of the disease.
Sedatives are recommended to reduce the activity of vegetative reactions. Treatment begins with herbal remedies (St. John’s wort, motherwort, valerian), and if they are ineffective, light tranquilizers are added. Antidepressants are used to stabilize the psychoemotional background. Neurometabolic stimulants and multivitamin complexes have a good effect.
The symptom is often provoked by emotional lability, so psychotherapy is an important component of treatment. Patients are recommended individual and family psychological correction. Physiotherapy techniques are used to normalize the state of the nervous system: neuro-sedative massage, reflexotherapy, balneotherapy. Sanatorium-resort treatment is shown.
For thyroid tumors, surgical intervention is prescribed: economical resection for benign nodes, subtotal or total removal of the organ for malignant neoplasms. With neoplasms of the brain in the hypothalamus, the help of neurosurgeons is required. Doctors perform excision of the pathological formation, supplement the treatment with radiation therapy.
