Symptoms of low blood pressure
introduction
According to the medical definition, low blood pressure (hypotension) is present if it is below 100/60 mmHg. In Germany about 2-4% of the population suffer from it, the majority of which are women.
Low blood pressure can have many different causes, which can be completely harmless in nature. However, it can also indicate organic or, in rare cases, dangerous diseases and should therefore be clarified if there are additional symptoms.
Blood is transported through the body by means of a heartbeat and supplies organs and tissues with nutrients and oxygen. How much and how quickly blood circulates through the body is determined not only by the work of the heart, but also by the blood pressure, for example. Blood pressure is therefore an important factor in ensuring that nutrient-rich blood reaches the brain, for example.
If the blood pressure is only slightly decreased, it is not symptomatic in most of the people affected. However, if the pressure is too low, for example to transport the blood fast enough or in sufficient quantities into the tissue or organs, a wide variety of noticeable symptoms can become noticeable.
What are the symptoms of low blood pressure?
If you have low blood pressure (arterial hypotension) the blood pressure is below the normal limit, i.e. it is lower than normal. This can result in very different symptoms, which can, but do not have to, occur individually for each individual. The following are the most common symptoms, from common to rare:
- Dizziness (often after getting up)
- Darkening of the eyes and flickering of the eyes
- See asterisks
- Fatigue and exhaustion
- cold hands and feet
- Headache or pressure
- Ringing in the ears and pressure
- Palpitations
- Listlessness
- insomnia
- Chest tightness
- Disturbances in consciousness to the point of fainting
Dizziness from low blood pressure
Low blood pressure often leads to dizziness, which is often accompanied by "starry eyes". Many of those affected also “go black in front of their eyes” and have the feeling of tipping over. Because not enough blood reaches the brain and it is not adequately supplied for a very short period of time, dizziness can occur. Often times, dizziness can be felt when people with hypotension stand up. This causes the blood to sink into the legs and cannot be pumped back to the heart and brain quickly enough.
Especially in the morning before straightening up, people with low blood pressure should first sit on the edge of the bed. This can get the circulation going and prevent dizziness. Those affected often get dizzy if they have to stand for a long time.
Standing for long periods of time causes too much blood to remain in the legs. As a result, the brain cannot be adequately supplied and dizziness is triggered. People with low blood pressure also feel dizzy, especially in summer. Here the vessels in the brain are widened and the blood pressure drops even further, which in turn causes dizziness symptoms to occur more quickly.

Fatigue from low blood pressure
Fatigue and fatigue can also be triggered by low blood pressure, especially if it persists over a long period of time. As already explained in the section on dizziness, this leads to an insufficient supply (insufficient perfusion) of the brain, as the low pressure cannot transport the blood sufficiently into the brain.
Fatigue is particularly noticeable during the summer with hot temperatures. When it is warm, the blood vessels expand physiologically to cool the body. However, the widening of the blood vessels also causes the blood pressure to drop even further, increasing the anemia in the brain and causing fatigue, among other things.

Low blood pressure with a high pulse / racing heart
The pulse can be equated with the heartbeat. From a pulse that is too high (Tachycardia) is spoken when the heart beats more than 100 times a minute. This too fast beating of the heart can often be felt by those affected and is then referred to as a racing heart.

The symptom combination of low blood pressure and high pulse can result, for example, from anemia. Anemia is most often caused by an iron deficiency, then one speaks of the so-called iron deficiency anemia.
The lack of blood can result in low blood pressure, which creates the risk that organs and tissues are no longer adequately supplied with oxygen. The heart tries to avert this undersupply and consequently beats with an increased beat frequency, which leads to a high pulse. Since the body generally tries to keep the circulation stable in spite of low blood pressure, other causes can cause a temporarily high pulse or a racing heart. If the blood sinks into the leg veins after sitting or standing for a long time, this can lead to what is known as neurocardiogenic (vasovagal) syncope come. This leads to a brief loss of consciousness as the blood remaining in the legs lowers the cardiac output. This results in low blood pressure. In order to compensate for this, the pulse rises briefly.
In addition to blood deficiency and neurocardiogenic syncope, other causes such as an overdose of antihypertensive drugs, bleeding (for example in the gastrointestinal tract) or excessive fluid loss can lead to low blood pressure and consequently a high pulse.

Palpitations with low blood pressure
When the heart beats, the affected person feels his own heartbeat very clearly. The palpitation of the heart is a typical reaction to low blood pressure. It's an increased heart rate, so the heart beats faster. The pulse rises accordingly. The body tries to compensate for the lack of blood flow caused by the low blood pressure. So palpitations for this reason have nothing to do with stress or excitement. People have palpitations even though they are in a normal or even relaxed and calm situation. An example of this is lying on the sofa. The low blood pressure can also cause heart palpitations when you get up from lying or sitting.
Palpitations with low blood pressure
The well-known stinging of the heart describes a sharp pain in the area of the chest, in close proximity to the heart. So it is a pain roughly at the level of the second to fifth rib behind the breastbone, which, however, can only be narrowed down by those affected. There may be a connection with low blood pressure, but it is not absolutely necessary. For this reason, the term "heart pounding" is very broad in colloquial language. The pain is usually sudden and very severe. The pain can come at different intervals. In addition, pain can be irradiated into other parts of the body, such as a shoulder or arm. This should be carefully observed and reported to your doctor in order to rule out diseases such as a heart attack.
Low blood pressure with a low pulse
Many athletes have relatively low blood pressure and a slow pulse at rest. In most cases, this is an adaptation of the cardiovascular system and should not be a cause for concern. However, a low pulse and blood pressure can also be caused by hormonal disorders. Above all, this includes hypothyroidism (Hypothyroidism), in which too few thyroid hormones T3 and T4 are produced. Since these hormones increase the heart rate and blood pressure, a deficiency can lead to them being too low.
Antihypertensive drugs such as beta-1 receptor blockers (e.g. metoprolol) can also lead to hypotension and bradycardia if overdosed or incorrectly used.

Tremors from low blood pressure
Trembling is also a typical symptom of low blood pressure. If there is sudden circulatory weakness, which is triggered by low blood pressure, symptoms such as dizziness, nausea or sweating often also result in tremors in the extremities or all over the body. Here, too, the tremor is triggered by a temporary and short-term insufficient supply, which restricts brain function.

Nausea from low blood pressure
Nausea is a typical side effect of low blood pressure.Above all, low blood pressure leads to nausea, if dizziness is present or has preceded it. If, for example, low blood pressure leads to a circulatory disorder in the organ of equilibrium, nausea and dizziness can suddenly occur. Low blood pressure related nausea mostly occurs in the morning. This can also lead to dizziness. Particular care should be taken to ensure that a nutritious breakfast is eaten.
Patients affected by low blood pressure also often report that they do not have a proper appetite. The lack of food intake can increase nausea and dizziness. Since internal organs are not adequately supplied with blood due to the low blood pressure, they can no longer adequately fulfill their task. The same goes for the stomach. After eating, the food is difficult to digest and therefore often causes nausea, which in many cases can also be accompanied by vomiting.

Headache with low blood pressure
Headaches are known to almost everyone. Due to the reduced blood flow to the brain, headaches are a symptom of low blood pressure. The pain can appear suddenly or gradually. In addition, it is possible that the headache is sharp, dull (similar to a migraine), pulling, pressing or pulsating. The pain intensity varies from barely noticeable to very strong.
Which area of the head is affected differs from person to person. The pain can be on the forehead, encompass the whole head, lie centrally, be placed on the temples, but also pull up from the neck up into the head, often involving tense shoulder and neck muscles. They can occur regularly, but also irregularly. Head jokes can lead to sensitivity to light and noise.
The pain is felt to be particularly severe when the person concerned does not drink enough fluids or the body is not supplied with sufficient oxygen.
Headaches can also be caused by other causes besides low blood pressure. The range of variations in the causes of headaches is very large, so a doctor should be consulted in the event of long-lasting pain. It is important to have a precise description of the pain.

Migraines with low blood pressure
Migraine is a condition in which headache attacks occur periodically. An association with low blood pressure is likely, but migraines often occur independently. The migraine attacks can be very different. However, a rough distinction is made between different phases and their symptoms, which not every person affected necessarily has. The heralding phase can last hours or up to two days. Even before the actual pain attack, one suffers from irritability, mood swings, tiredness or sensitivity to light and noise. This is followed by the typical headache, which can also last for hours, but oh days. The mostly severe headache occurs on one side or on the whole head. It is a pulsating pain is localized especially in the area of the temples, eyes and forehead. This often goes hand in hand with perceptual disorders that can result in dizziness, impaired vision, speech disorders or disorientation. In addition, symptoms of nausea and vomiting often exist.
Tingling sensation from low blood pressure
Tingling is a term used to describe numbness. In addition to nerve disorders, these primarily indicate a lack of blood flow. The circulatory disorder can be caused by low blood pressure, which is perceived as a tingling sensation, especially in the hands and feet. This is due to the fact that, in comparison, the path of the oxygen-rich blood from the left heart to the feet or hands takes longer than to the nearby organs. Since the blood cannot be transported to the hands and / or feet quickly enough, circulatory disorders due to low blood pressure are particularly noticeable there.
Difficulty breathing due to low blood pressure
If the low blood pressure is caused by a lack of blood (anemia), the anemia - especially when exerted - can also cause shortness of breath as a result. This is due to the fact that, for example, a lack of erythrocytes means that not enough oxygen can be transported, which can be felt by shortness of breath, especially during exercise, where there is a higher consumption of oxygen. This is because the lungs can no longer be adequately supplied with oxygen either.

When do you faint?
Fainting means that you have no control over your consciousness for a brief moment (a few seconds), i.e. you are helplessly at the mercy of the situation. The risk of injury in the event of a fall is dangerous. In this case, the brain is no longer adequately supplied with blood because the blood pressure is too low. The result is a circulatory disorder in the brain. Typically, fainting occurs due to a too fast change from lying or sitting to standing. So this has to be avoided. The blood sinks into the leg vessels, which means that the brain is undersupplied with oxygen. Shortly before passing out, one is plagued by severe dizziness or sweating. If you notice this you should sit down or lie down immediately and get up very slowly and avoid hectic movements.
Symptoms around the eyes
Symptoms in the eyes that are triggered by hypotension are also caused by a short-term undersupply of the brain or eyes. This leads to blurred vision, “star-seeing” or “blacking out” for those affected. The symptoms in the eyes are usually accompanied by dizziness and often arise when getting up too quickly after sitting or lying down for a long time. If the symptoms also occur when moving, you should definitely consult a doctor, as the symptoms in the eyes can have dangerous consequences, especially in traffic. If the eyes are not supplied for a long time, the retina and optic nerve can also be damaged, which in the worst case can lead to blindness.
Fibrillation of the eyes with low blood pressure
Eye flicker (flickering scotoma) is a visual disorder in which an area of the field of vision is lost. This can occur on one or both sides. Often this imperceptible area is zigzag-shaped or star-shaped and surrounded by a light border. In addition, blurred light phenomena or flashes can occur when the eyes flicker. This is usually accompanied by a sensitivity to light. As a rule, the eye flickering lasts a few minutes and is different in severity in each person. Eye flicker can be a symptom of low blood pressure.
See asterisks when the blood pressure is low
Seeing asterisks means that those affected see bright yellow to white flashes of light. The normal field of vision is therefore severely restricted. Seeing asterisks is often associated with dizziness and is a typical symptom of low blood pressure. This seeing lightning usually only lasts for a very short time. It occurs particularly frequently when the body changes quickly. This means that you can get from lying down to standing too quickly, for example. The blood sinks in the legs, causing a lack of oxygen and blood deficiency in the brain. The eyes are also affected. The retina only works to a limited extent, which is why the flashes of light occur. Usually the symptoms do not last long, a few seconds at most. The blood circulation is stimulated quickly and the symptoms disappear completely.
"Black before eyes" with low blood pressure
The field of vision turns black after seeing flashes of light or stars and is a common symptom of low blood pressure. The field of vision is dark so that it can no longer be seen. This also happens when you quickly change your body position. Just like seeing asterisks, there is a lack of oxygen in the brain or in the retina. The photoreceptor cells temporarily stop working if the lack of oxygen persists. As a result, you can only see black. This condition is short-lived. If everything is supplied with normal blood again, you can quickly regain normal vision without any restrictions.
Ringing in the ears due to low blood pressure
Ringing in the ears, as well as dizziness or visual disturbances, are usually caused by insufficient blood supply to the brain. It manifests itself as a hissing noise or a high-pitched whistle, as is also perceived in tinnitus. If the brain is not supplied with enough blood, the ringing in the ears is also often accompanied by symptoms such as dizziness or visual disturbances.

Freezing from low blood pressure
The body surface is warmed mainly by increased blood flow. When blood pressure is low, however, not enough blood reaches the surface in the small vessels. As a result, patients with low blood pressure have a reduced blood flow and therefore often an increased feeling of cold and freeze faster than other people. This is why most people have cold hands and feet, as it is the most difficult thing to get the blood to the ends of the arms and legs with low pressure.
Ear pressure from low blood pressure
Ear pressure is a very unspecific symptom that is not necessarily associated with low blood pressure. The ear pressure can be described with the following symptoms, which are always differently pronounced. Starting with a harmless feeling of pressure, which can be compensated by swallowing (like in an elevator), to severe and uncomfortable stabbing pain, dizziness, ringing in the ears, hearing noises in the ear, impaired hearing and ending with deafness. In addition, some people describe a feeling in the ear as if it were blocked. In summary, it can be said that everyone affected has an uncomfortable feeling in the ear when they suffer from ear pressure.
Sensation of pressure in the head with low blood pressure
Head pressure is usually understood to be a headache that is very pounding and pressing. One has the feeling that the brain is pressing against the skull. Often these headaches are perceived by the patient as dull, throbbing and bilateral, i.e. affecting the whole head. Often there are also side effects. These can take the form of nausea, vomiting, body aches, and general malaise. This makes the patient's condition worse. A feeling of pressure in the head is very unspecific and not necessarily due to low blood pressure.
Potency disorders with low blood pressure
The erectile dysfunction, also called impotence, describes the inability of the man to have sexual intercourse. The affected person is unable to get an erection for a long period of time (approx. 6 months) or to keep it long enough for successful sexual intercourse. This means that the male member, despite sexual arousal, does not stiffen properly. Circulatory disorders can prevent an adequate erection. Blood pressure that is too low can also play a role. Blood flow is very important for erection because the stiffness of the penis is triggered by a congestion of blood. So it may be that too little blood flows into the male member.
