Anaemia - when anaemia makes you tired and listless

Pallor, low energy, general weakness - if this applies to you, you may be suffering from anaemia. Women are more often affected by this condition, but men are not spared either. Anaemia can have a wide variety of causes, which always require clarification and appropriate treatment. Anaemia can have serious consequences, especially in patients with heart failure or circulatory disorders or in people who are about to undergo an operation. When do we speak of anaemia? Red blood cells play a major role in this clinical picture: either too few are produced or too many are broken down by the body. Another cause of anaemia is blood loss.

Iron deficiency as a common cause

Anaemia is actually a symptom, not a disease in its own right: the body needs various building blocks to produce blood - including vitamin B12, the hormone EPO and iron. If one of these is missing, for example in the case of iron deficiency, anaemia can be the result. However, chronic blood loss, inflammation in the body or a tumour disease can also be responsible.

The haemoglobin level of the person affected is decisive for a diagnosis - low haemoglobin means too few red blood cells and is synonymous with anaemia. It is often very complex to find the cause - our specialists at Bethesda Hospital are happy to take on this important task.

More than just tiredness: signs of anaemia

The typical symptoms of anaemia are varied and often unspecific: many sufferers complain of reduced performance, shortness of breath, tiredness, paleness, dizziness or headaches. However, palpitations, i.e. an accelerated heart rate at rest or pulse during minor exertion, can also occur. Anaemia often goes unnoticed for a long time if it develops slowly and does not cause any major symptoms. However, as soon as symptoms such as blood in the stool or urine appear, you should have them checked out immediately.

Usually too few red blood cells

In order to diagnose anaemia, our experts always carry out a blood test. A blood count is taken, which provides a lot of information and can already point in the direction of the cause. This allows a direct assessment of whether the red blood cells are of a normal consistency and size. It is also analysed whether other blood cells are also reduced, for example the white blood cells or platelets. As soon as anaemia is confirmed, further investigations are necessary.

The most common parameter used in the diagnosis is the haemoglobin concentration, i.e. the amount of red pigment in the blood. This is usually reduced when anaemia is diagnosed. The WHO defines a haemoglobin level of 130 to 170 g/L (grams per litre) as normal for men and 120 to 160 g/L for women. All values below this are considered anaemia - of course the normal values for children and adolescents are different.

What can be done against anaemia?

At Bethesda Hospital, anaemia can be investigated on an outpatient or inpatient basis. Particularly in older patients in a reduced general condition or with concomitant illnesses, an inpatient investigation is often more sensible and more comfortable. In most cases, further blood tests are also carried out, and in certain cases a gastroscopy or colonoscopy or a bone marrow puncture. These examinations are offered by the Department of Internal Medicine in co-operation with other specialists at Bethesda Hospital.

It is very important not to start treatment for anaemia until the causes have been clarified, as the treatment can be very varied. Possible forms of therapy are

  • Replacement of missing building blocks for haematopoiesis (iron, vitamin B12, EPO) with preparations
  • in more severe cases: Replacement of blood through transfusions
  • Treatment of an underlying illness, e.g. a stomach ulcer or gastritis


As a special service for anaemia, we offer you comprehensive diagnostic and therapeutic options for causes in the gastrointestinal tract. We carry this out in collaboration with the gastroenterologists at the Clarunis University Abdominal Centre on site at Bethesda Hospital. We also work on an interdisciplinary basis with the haematologists at the Bethesda Oncopraxis for more complex haematopoietic cases.

Anaemia is the most common blood disorder

In Europe, around 5% to 10% of all people suffer from anaemia - in women of childbearing age the figure is as high as 20%. Although anaemia can occur at any age and in both sexes, women are more frequently affected - the same applies to people of an older age.

Hämoglobin ist der rote Blutfarbstoff. Dieser ist notwendig für den Transport von Sauerstoff und Kohlendioxid im Körper. Ein tiefes Hämoglobin in der Blutuntersuchung bedeutet, die einzelnen roten Blutkörperchen weisen zu wenig Hämoglobin auf und/oder die Anzahl der roten Blutkörperchen ist vermindert.
Meist bedeutet dies eine Blutarmut und das kann zu verschiedenen Symptomen und Problemen führen.

Die Organe des Körpers können dann nicht mehr optimal mit Sauerstoff versorgt werden. Das kann verschiedenste Symptome wie Blässe, Atemnot, Schwäche, Schwindel, Kollapsneigung oder  Kopfschmerzen verursachen.

Im Bethesda Spital kann eine Blutarmut ambulant oder stationär abgeklärt werden. Gerade bei älteren Patientinnen und Patienten in reduziertem Allgemeinzustand oder mit Begleiterkrankungen ist eine stationäre Abklärung oft sinnvoller und angenehmer. Meistens kommen weitere Blutuntersuchungen dazu, in gewissen Fällen auch eine Magen- oder Darmspiegelung oder eine Knochenmarkspunktion. Diese Untersuchungen bietet die Klinik für Innere Medizin in Zusammenarbeit mit anderen Spezialistinnen und Spezialisten im Bethesda Spital an.

Als Blutkrebs bezeichnen wir eine bösartige Veränderung von Blutzellen, bzw deren Vorläufer im Knochenmark, wo das Blut gebildet wird. Selten ist eine Anämie eines der Symptome von Blutkrebs. Viele häufiger sind jedoch Ursachen wie Eisenmangel, Blutverlust oder Entzündungen im Körper. Wichtig ist es jedoch immer der Ursache der Blutarmut auf den Grund zu gehen.

Die typischen Symptome einer Anämie sind vielfältig und oft unspezifisch: Viele Betroffene klagen über verminderte Leistungsfähigkeit, Atemnot, Müdigkeit, Blässe, Schwindel oder Kopfschmerzen. Aber auch Herzrasen, also ein beschleunigter Ruhepuls bzw. Puls bei kleiner Belastung, kann auftreten. Oft bleibt eine Blutarmut, wenn sie langsam entsteht und keine grösseren Beschwerden verursacht, lange unbemerkt. Sobald aber Symptome wie Blut im Stuhl oder Urin auftreten, sollten Sie diese umgehend abklären lassen.
