Hot flashes without menopause

Hot flashes are mostly known as complaints of menopausal women. Hot flushes are short-lasting and sudden warming spurts. It can cause sweating, palpitations or redness. Although menopause is often cited as a cause of hot flushes, it can also have other causes. For example, hormonal imbalances or changes, stress, medications, allergies and other factors can cause hot flashes.


During the menopause, there are fluctuations in the hormone level in the woman. These are probably responsible for the occurring hot flashes. But even without menopause, hot flashes can occur. On the one hand, internal processes of the body can be responsible for this. These include, above all, changes in the thyroid or low blood sugar. External influences can also cause hot flashes. These include hot foods, medicines, stress or alcohol.


The thyroid is responsible for the production of vital hormones. The thyroid hormone regulates many metabolic processes of the body. In hyperthyroidism too much of the hormone is released into the body. Sufferers are often nervous, lose weight and have a faster heart rate.

But the thyroid hormone also has an important influence on temperature regulation. People with hyperthyroidism may be more sensitive to heat. In addition, there may be an increase in sweating in hyperthyroidism. Therefore hot flashes can be caused by hyperthyroidism.

anti hormone therapy

The hot flashes of menopause are probably due to a change in hormone levels. Especially the decline of the female sex hormones seems to have an effect. Certain medications have a similar effect on the body. Some of these drugs are used, for example, in the treatment of breast cancer. They inhibit the action of estrogens and thus produce an artificial estrogen deficiency. This can cause hot flashes.

But other medications can cause hot flashes or similar symptoms. These include above all drugs that have an influence on the regulation of vessel size. Examples of these are nifedipine or nitroglycerin.


Stress triggers a number of processes in the body. The body is put on high alert, hormone levels change. This can disturb the body's heat regulation in its equilibrium. Therefore, stress may be responsible for hot flashes without menopause.
It does not always have to be a negative stress. Even happy or unforeseen events put the body in a higher activation state, which can cause hot flashes.


An allergy causes an immune reaction against a normally harmless substance. The immune system is activated, which releases a number of messenger substances. Some of these messengers may have an effect on vessel size or heat regulation. Therefore, even during an allergy sensations may occur, which are described as hot flashes. Typically, allergic symptoms only occur after exposure to the causative agent. Since especially food allergies can have very serious consequences, an allergy should be clarified by a doctor.


Hot flushes are also often described during hypoglycaemia. The blood sugar level is the amount of circulating sugar in the blood. Because insulin lowers blood sugar, too much insulin can cause these symptoms. In a healthy person, the blood sugar level is regulated by various hormones. This rarely leads to derailment.

However, with prolonged fasting, it may happen that the body can no longer mobilize sufficient reserves to keep the blood sugar level constant. In this case, a slight hypoglycaemia may occur. In the healthy this is usually not dangerous. However, hot flashes may occur during hypoglycaemia. The causal treatment is the intake of carbohydrate-containing foods.


The diagnosis of hot flashes without menopause is primarily a search for the cause of the hot flashes. Important indications are above all duration, strength and triggers of the hot flashes. For example, certain causes, such as allergies or low blood sugar, occur only in certain situations.

If medications are the cause of hot flashes, then the occurrence of hot flashes in a temporal connection with the ingestion is diagnostically important. It is possible that further examinations such as interception, an ECG or laboratory tests will be carried out. This should exclude dangerous causes such as heart disease or hormonal imbalances.

Accompanying symptoms

Hot flashes do not have to be the sole symptom. Other symptoms often occur in connection with the hot flashes. They can have the same cause as the hot flashes. It is also possible that they occur due to the hot flashes or trigger them. Frequently, sufferers report simultaneous or staggered sweats. They are usually a reaction of the body to the hot flashes. Increased sweating should lower the body temperature.

It can also cause redness. These can also occur as a reaction of the body to a supposedly or actually too high body temperature. In addition, tachycardia can occur. Hot flashes can lead to insomnia and restlessness. Some sufferers report dizziness associated with hot flashes. Accompanying symptoms can provide important clues to the cause of the hot flashes. Especially with pronounced accompanying symptoms such as weight loss or elevated temperature, a doctor should be consulted in case of doubt.

Treatment / therapy

The treatment of hot flashes depends mainly on the cause. Without causal treatment, the symptoms often can not be permanently alleviated. In case of strong concomitant symptoms or no improvement, a doctor should be consulted.

Hot flashes can often be limited or mitigated by various measures. These include weight loss in overweight and paying attention to correct clothing. This should be appropriate and airy temperature. By wearing several layers of clothing, the clothes can be more easily adapted to the current temperature perception. It is often recommended to sleep in airy bedding and cool temperatures at night. Certain foods, such as coffee, alcohol, or spicy foods, can increase or trigger hot flashes. Therefore, it can be helpful to avoid them. Even light exercise or endurance sports can improve or reduce hot flashes.

Duration / Forecast

The duration and prognosis of hot flashes without menopause also depends strongly on the cause. Most causes can usually be treated well. Low blood sugar, allergies or spicy foods are short-term triggers of hot flashes. If appropriate situations are avoided, the hot flashes should improve in a short time.

Especially hormonal causes, depending on the exact cause, often last for a longer period of time. Often, they must be causally treated by a doctor before improvement occurs. If medications are the cause of hot flashes, a change in the intake or the active ingredient can bring improvement in a shorter time. Stress can cause hot flushes in the short term, but also over a longer period of time.
