These symptoms may also include some local symptoms, but most of these symptoms originate from whole-body or systemic diseases, so although they might be local symptoms, they are systemic manifestations. Most of the systemic type symptoms usually affect the current state of the body and are at first sight common symptoms such as fatigue, sweating or feeling hot, which may not always be associated with disease but should always be related to other symptoms.

Very often these symptoms include changes in body temperature, which, unless they are related to some obvious external cause, can be considered as symptoms of disease, because the body usually maintains a permanent and static temperature with only minor variations during the day and according to the state of physical activity of the person. Any major deviations, whether sudden and acute or chronic and prolonged, signal a disturbance in the internal state of the organism.

Some of these systemic symptoms are associated with, linked to, or arise as a consequence of other symptoms. Chills and shivering are usually associated with higher body temperature and fever, where the body tries to get rid of the excess heat by relaxing muscles and skin pores and also, for example, by sweating. As sweating is also one of the signs of the excretion of pollutants through the skin, these symptoms usually occur with infections.

Feeling hot and sweating

Feeling hot may not always be a serious problem or a symptom of poorer health, as the body contains a number of regulatory mechanisms and these react to the actual body temperature. However, if other symptoms are also present, most of the time the hot feeling is a symptom for inflammatory and infectious diseases associated with fever or respiratory syndrome. Also, with problems with hormone levels, a person may have a sensation of heat, similarly with intoxication.

Similarly, sweating is one of the body's coping mechanisms for dealing with heat and is quite common with more physical activity or exposure to extreme ambient temperatures. At the same time, however, excessive sweating is a symptom that should not be ignored as it is related to diseases of the digestive, respiratory and cardiovascular systems. It occurs to an increased extent in febrile and infectious diseases, but also in many life-threatening and acute conditions and deterioration of the body.

Elevated temperature as a warning signal

Elevated body temperature is a temperature of 37 to 38 degrees Celsius. Sometimes it does not have to be anything serious, the organism overheats in this way due to excessive physical activity or the influence of the ambient temperature, which is even higher. On the other hand, if there are other suspicious symptoms and manifestations, the elevated temperature should not be underestimated. For example, these are often respiratory diseases such as bronchitis, influenza, tonsillitis, tuberculosis of the lungs or whooping cough.

In addition, elevated temperature also accompanies cancer and many times later develops into fever, for example in various infections and inflammations of bacterial and viral type. It can also be a symptom of myocarditis or endocarditis, which are related to the heart. Some inflammations in the body are also accompanied by a slight increase in temperature, for example, shigellosis, laryringitis, tick-borne encephalitis, ovarian inflammation in women, and also some venereal diseases such as gonorrhoea.

Always watch out for fever

Fever, unlike temperature, is always a symptom of illness in the body, a fever is said to be present when the body temperature is greater than 38 degrees. Fever is typical in infectious diseases such as malaria, leptospirosis, Ebola, paratyphoid fever, typhoid fever, influenza, cytomegalovirus infection, tick-borne encephalitis, infectious mononucleosis or tonsillitis. Sometimes it happens that fever develops gradually from an elevated temperature, other times it comes on suddenly and acutely.

Although fever is most often associated with diseases of the respiratory system, it is also associated with inflammation of the heart and cardiovascular system, some infectious diseases of the digestive system and diseases of the blood and hematopoiesis, such as leukaemia. It may also accompany in some cases various poisoning and intoxication or inflammations of a traumatic nature, which can sometimes directly threaten a person's life, such as peritonitis.

Both chills and chills also mean something

Chills and chills usually accompany febrile illnesses in particular. Chills are a feeling of cold and chills occur most often in infectious diseases that are characterized by fever, such as yellow fever, typhoid fever, malaria, haemorrhagia, but also in our country quite widespread and well-known influenza. It can also sometimes accompany herpetic viral diseases or heart disease, for example in infective endocarditis. It is also not exceptional in kidney stones.

Shivering is a condition where the whole body also shivers and trembles, but it is not a sensation of cold and lowering of temperature. Shivering is also typically accompanied by chills, for example with flu, shigellosis or malaria, but it can also be alone. It sometimes accompanies states of intoxication or alcohol abuse, and may also occur in some neurological diseases such as cerebral palsy or in epilepsy. In digestive problems, it already appears more rarely, but there are also such cases.

Decreased body temperature and chills

Reduced body temperature is a symptom of a failure of the thermoregulatory mechanisms in the body, and these may be damaged by disease or by external factors. For example, in hypothermia, the body's body temperature is lowered due to the low ambient temperature, as the body can no longer prevent cooling by its own mechanisms. Coldness usually occurs over a long period of time as a state of feeling cold and is related to problems with the vascular system and low hormone levels.

Weakened immunity as a symptom

If a person often has any infectious diseases, it always means a weakening of immunity or excessive exposure of the body to extreme conditions. Neither is good and, moreover, a weakened immune system poses a permanent risk. Immunity can also be lowered by, for example, the administration of immunosuppressants or drugs with such adverse effects, then this is understandable and frequent infections are one of the unwanted but necessary effects that must be endured.

However, when it comes to the weakening of immunity on the basis of disease, this is a warning. Thus, frequent infections are typically manifested, for example, by AIDS, but also by allergies. If someone is troubled by frequent lower respiratory tract infections, this is due to insufficient filtering function of the upper respiratory tract. In addition, various complications also threaten with lung diseases due to weak immunity. Immunity testing should be done by immunologists who can also determine the exact cause.

Problems with a full nose

Frequent sniffling and a full nose usually indicate problems in the upper respiratory tract, for example, in infections and inflammations such as tonsillitis, nasopharyngitis and the like. Many times, a full nose and sniffling are also caused by excessive mucus production, which in turn is typical for diseases of the lower respiratory system. It can also be an allergic reaction during the peak season in spring and autumn. Young children in particular have the most problems with a full nose, so it is a common symptom in them.

Exhaustion, malaise, fatigue and dizziness

Examples of systemic symptoms, which can indicate diseases or health problems throughout the body, include excessive fatigue or tiredness. These symptoms are typical of inflammatory and infectious diseases, which are also accompanied by elevated body temperature to fever. Sometimes they are related to excessive physical fatigue or mental fatigue when the body is under heavy stress. exhaustion can also be related to musculoskeletal fatigue. Fatigue is usually associated with malaise.

It accompanies influenza and diseases of the central nervous system, when the brain is also affected by some inflammation or infection. It can also make a person malaise when there are problems with metabolism. Vertigo also tends to occur in these illnesses, as in febrile illnesses or heart problems when the brain is not sufficiently engorged. Excessive and intense occurrence of these symptoms should always be consulted with a doctor.
