This night sweating can severely restrict the person's sleep and make adequate recovery almost impossible.
Harmless causes of sweating at night are, for example, general illnesses that are associated with a fever, such as a cold. The increased temperature can lead to temporary sweating during the night.
Night sweats can also occur in the context of a tumor disease as part of the so-called "B symptoms" (night sweats, fever, weight loss) and thus rarely have a malignant cause.
For this reason, a doctor should be consulted urgently if sweating persists at night.

root cause

Excessive sweating at night is often caused by harmless causes. The most common explanation is poor sleeping conditions.

The causes of profuse sweating at night (Night sweats) can be diverse. In most cases, the high secretion of sweat during sleep has quite harmless causes. If the heavy sweating at night is based on serious illnesses, further symptoms can usually be recognized in the affected patient.

In this context, play mainly Stress, heartache, anger and anxiety which are processed during sleep play a crucial role.

Other causes for the temporary occurrence of night sweats are quite frequently observed simple infectious diseases. Especially with patients who Viral diseases like the flu (or those with flu-like symptoms), large amounts of sweat are produced and secreted during sleep. If there is an infection behind the development of night sweats, the symptom usually disappears after a few days.

Furthermore, the occurrence of night sweats is also considered Symptoms of more complicated infections. tuberculosis is associated with a number of other symptoms, for example, in most cases with profuse sweating at night.

With this constellation of symptoms one speaks of the so-called B symptoms. The B symptoms are also typical for infectious diseases such as tuberculosis and HIV, but they occur much more frequently with malignant diseases. Especially patients suffering from lymph gland cancer or leukemia develop fever, weight loss and sweating at night. The so-called B symptoms can, however, provide an initial indication of tumor diseases of any kind.
In this context, however, it should be noted that light sweating at night is not considered noticeable. And weight loss only plays a role if it occurs without changing eating habits (that is, without dieting or the like) and without increasing physical activity. In those cases in which profuse sweating occurs at night without a detectable disease or hormonal cause, one speaks of so-called idiopathic night sweats.

diagnosis

Since the causes of profuse sweating at night can be so varied, the diagnosis is causal irregularity not always easy within the organism.
Especially that detailed doctor-patient conversation (anamnese) gives the attending physician an initial insight into the possible causes of night sweats. During this conversation, the period in which sweating occurs at night plays a major role (since when?) and the Extent of perspiration (Are clothes and / or bedding soaked?) A crucial role.

In addition, the doctor asks the patient concerned about during the anamnesis discussion other abnormalitiesthat could give an indication of the underlying disease. Also performing a extensive physical examination can be useful when looking for the cause. During this examination, the doctor usually first gets a rough overview of all relevant organ systems (lung, heart, Abdomen). In addition, in most cases all will huge Lymph nodes examined for possible enlargement.

Depending on the doctor's first assessment, you can then special tests be performed. For example, an HIV test should be performed to detect a possible HIV infection.

Sweating at night with a fever

Numerous different pathogens can cause infectious diseases that are associated with fever. These include viruses, bacteria, fungi, worms, and parasites.
When such pathogens trigger an acute infection, in most cases there is an increase in body temperature.
This rise in body temperature is called "fever" and is a result of the activities of the body's own defense system and its messenger substances, since certain defense mechanisms are activated when the body is heated. The fever causes symptoms such as shivering and chills.

Acute infectious diseases, in particular, are associated with increased sweating at night, such as the flu caused by viruses (influenza). Heart inflammation (endocarditis) is a typical disease that is accompanied by fever, chills and night sweats.
This inflammation of the inner lining of the heart caused by bacteria can occur acutely with pronounced symptoms or over a longer period of time slowly and undetected (subacute). People with heart valve defects or an artificial heart valve are particularly affected by a subacute course of the disease. In these cases, increased sweating can be an important first symptom of such hidden endocarditis.

Certain diseases (which are rather rare in our latitudes) such as malaria can be associated with a characteristic fever with a stressful alternation of sweats and chills. In these cases, increased sweating at night can lead to restless sleep.

Chronic diseases such as tuberculosis, HIV infection or AIDS can lead to increased sweating at night and occurring over a longer period of time. In the case of chronic illnesses, the body's own defense system may be permanently activated, leading to attacks of fever and, as a result, increased sweating.
At the beginning, tuberculosis often does not show any typical symptoms. Increased sweating in the morning together with a fever, weight loss and cough can be the first signs of the disease.

Some cancers can also be associated with increased night sweating and fever. If, in addition to an unwanted severe weight loss in a short time, fatigue and general malaise occur, a serious illness such as leukemia (blood cancer) may also be behind the symptoms.

If the temperature rises over a long period of time or if the temperature is high or if you have a fever combined with profuse sweating during the night, it is advisable to consult a doctor in order to find out and treat possible causes of the symptoms.

Sweating in the night with diabetes

There are two types of diabetes (diabetes mellitus), type 1 and type 2 diabetes. The common characteristic of the two types of the disease is that the body lacks the hormone insulin or that insulin cannot work properly.
Insulin is important for the body's cells so that the carbohydrates from food, which are broken down into sugar, can be converted into energy. Without insulin, the body's cells cannot absorb sugar from the blood and the blood sugar level rises.
As a result, the metabolism is severely disturbed and metabolic imbalances can occur, which are noticeable through certain symptoms. In general, at the onset of diabetes, there is increased thirst, increased urination, fatigue and nocturnal calf cramps. These symptoms often show up more clearly and earlier in so-called type 1 diabetes than in so-called type 2 diabetes.

An important warning signal for a dangerous hypoglycemia of the body cells (especially the brain nerve cells) are strong sweats. Heavy sweating combined with muscle tremors, cravings, weakness, dizziness and visual disturbances can indicate the possibly life-threatening condition.

In addition, the permanently increased blood sugar level in diabetes leads to nerve damage in various areas (diabetic neuropathy). If nerve damage in the autonomic nervous system occurs, profuse sweating can occur at night or during the day.

Typically, the initially increased tendency to sweat in the affected areas decreases again in the course of the disease, and as the nerves are progressively destroyed, perspiration is often reduced. In some cases with diabetes mellitus, profuse sweating of the face and neck occurs even while eating, which is known as gustatory sweating.

Even people who do not have diabetes may sweat profusely at night when their blood sugar levels are low. In addition to an unbalanced diet or alcohol, this can also be caused by special diseases (such as an insulinoma).

If diabetes mellitus is treated with insulin, for example, there can also be a nightly drop in blood sugar levels due to dosing or intake errors in the evening, which can be noticeable through increased sweating at night. In this case, the attending physician should be consulted in order to possibly adjust a more optimal insulin therapy.
