Tachycardia and diarrhoea

If there are accompanying symptoms such as diarrhea in addition to a racing heart, it could be an overactive thyroid. In this case, an increased production of thyroid hormones increases the effects of these hormones.This leads, for example, to symptoms such as a faster heartbeat, restlessness, nervousness, weight loss, restlessness, sleep disorders and an increased stool frequency up to an increased tendency to diarrhoea. Therefore, if you suspect hyperthyroidism, i.e. an overactive thyroid gland, in which several of the above symptoms occur, you should have your thyroid gland values determined in a blood test.

Tachycardia and shortness of breath

Shortness of breath and an increased heart rate is a normal reaction of the human body in many situations, such as after physical exertion, to compensate for the oxygen deficit and the exhalation of CO2. If, on the other hand, shortness of breath and tachycardia occur even at low levels of physical exertion, this may indicate a serious heart disease. A reduced pumping function of the heart muscle causes a reduced oxygen supply to the tissue. This can be caused by coronary heart disease, heart valve defects or various cardiac arrhythmias.

Tachycardia at night

Just as there are many causes for tachycardia in general, a fast pulse occurring at night with over 100 beats per minute can have many reasons that need to be differentiated precisely, which usually proves to be extremely difficult. Tachycardia occurs naturally when the oxygen demand of the body is increased, e.g. after a physical or psychological stress. Under the influence of hormones such as adrenaline, the heartbeat and blood circulation increase and energy reserves are provided.

In evolution, this had the advantage that one could flee in a stressful situation in case of danger. Nowadays, for example, fleeing from mental stress would not be very helpful or useful, but in stress situations, physical adaptation reactions still occur. Especially at night, when you want to get some rest, many people think about many things again and start to brood, which can often lead to a racing heart at night.

Another cause is the consumption of alcohol. Especially younger men who have drunk large amounts of alcohol can demonstrably have a higher risk of tachycardia at night. This phenomenon is known as the so-called Holiday-Heart Syndrome, it is an alcohol-induced atrial fibrillation, a disordered and too fast activity of the atria.

However, this is only a short-term cardiac dysrhythmia and will normalize itself again after the alcohol level has been reduced, but in the future you should pay more attention to your drinking habits. Finally, many other structural diseases of the heart can lead to tachycardia. It is therefore important to consult a physician if the symptoms are repeated and persist for a long time, as tachycardia can also conceal serious illnesses.
