Blood pressure is the pressure that occurs in the blood vessels as the blood is driven from the heart into the body and later back to the heart. High blood pressure makes the heart pump work harder and can be serious if you do not get it treated. The risk of cardiovascular disease and kidney problems in particular increases if you have high blood pressure.
Here you can read more about diseases and disorders that have to do with the heart, blood and lymph nodes.
Low blood pressure is in most cases completely harmless and does not require any treatment. Most people who have low blood pressure have no symptoms. If you have a sudden drop in blood pressure, you should sit down or lie down. Sometimes you may need to seek care.
Anemia means you have too little red blood cells in your blood. The red blood cells are needed for the body's various organs to get enough oxygen. Anemia can cause you to become tired, dizzy and have a headache. Often it is possible to recover the amount of red blood cells with the help of drugs.
Anemia due to too little iron is common and can make you feel tired and powerless. The most common cause of anemia is that you have lost blood. For example, it can be during menstruation or if you have a stomach or intestinal disease that causes bleeding. It may also be because you cannot absorb iron from the food.
Vitamin B12 is needed for the body to form red blood cells. If you have too little B12 you may have anemia. B12 is not produced in the body but you get it through the food. B12 is found in food from the animal kingdom, mainly in meat and dairy products.
Hemorrhagic disease is really a group of diseases. Hemorrhage means that you start bleeding more easily and that you can bleed longer than a person who does not have hemorrhagic disease.

Polycythemia means that you have too many red blood cells in your blood. It makes the blood flow thick. Polycythemia can be a disease but it can also be a consequence of other diseases. The treatment you receive depends on what form of polycythemia you have.
There are blood vessels in the body, so-called veins, that lead the blood back to the heart. In the legs, it is mainly the leg muscles that pump back the blood, for example when walking. Inside the veins of the legs are flaps, which act as valves for the blood to flow smoothly back to the heart. If a vein becomes very enlarged and winding, due to leaky flaps, it is called varicose veins.
If you have angina in your legs it can hurt your legs when you strain them, for example a shorter distance. This is because the blood is difficult to pass to the muscle cells. Smoking is the most common cause of getting leg cramps. But diabetes, high blood fats, high blood pressure and obesity also play a role in the development of the disease.
Vascular spasms are usually due to the constriction of one or more of the coronary arteries. As a result, the heart does not get enough oxygen, which is especially noticeable during physical exertion. Vascular spasms can reduce physical performance, but most can live about as usual. Having angina increases the risk of heart attack.
Blood circulation in a part of the body can be severely impaired by, for example, diabetes, vein obesity, smoking or severe cold injury. If you are not given care, the body part or parts of it may die. It is called cold sores or gangrene and is most common in fingers, feet, toes or legs.
Temporal artery is called inflammation in one's temporal pulmonary veins and sometimes in the branches that go to the eye. If you get treatment quickly you will be perfectly well, but if the inflammation is not treated you may lose sight of that eye.
There are several types of fat in the blood. Some are beneficial, others can be harmful. The fats that the doctor usually assess are cholesterol and triglycerides. Fat can begin to be stored inside the blood vessels if the levels of blood fat become too high. It can lead to various cardiovascular diseases.
A hernia, aneurysm, on the large body pulse vein in the abdomen means that a section of the pulse vein dilates. This can weaken the vessel wall. Most people who have such a hernia have no trouble with it, but if the hernia breaks it is life threatening because you get internal bleeding.
Blood that has solidified can form a so-called blood clot. Blood clots in the bone or other parts of the body can sometimes accompany the blood to the lung. There, the blood clot may get stuck and hinder the blood flow. Blood clots in the lungs can in some cases be life-threatening and must therefore always be treated as soon as possible.
A blood clot is because the blood lives and forms a blood clot in a blood vessel. It then becomes more difficult for the blood to pass. Blood clots in the bones that come off can accompany the blood and get stuck in the lungs. A plug that is detected and treated early is usually not dangerous. However, if it gets bigger, it can seriously hamper blood circulation.
