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.
