Hyperemia Causes

Since the past few days, you have been noticing some redness on your skin and the area which turns red, feels warm to touch. This redness might be due to hyperemia. Now you might ask what is hyperemia definition? Well, it is a medical condition, in which the blood in specific areas of our body gets congested. Whenever the blood gets congested in the capillaries, the redness on the skin appears. This congestion might occur due to some kind of obstruction or inflammation, which prevents blood circulation in the capillaries. Let us now see in details what are the hyperemia symptoms and the hyperemia causes.

Symptoms

The main hyperemia symptoms are:

• Redness of the area where the blood has congested
• The affected area feels warm to touch
• Flushing, i.e., involuntary skin redness, mainly on the face.

These symptoms usually indicate whether the person has hyperemia or not.

Causes

Now that you know about the hyperemia definition, and it's symptoms, let us now see what causes it. Also medically, as per the causes, different types of hyperemia has also been given.

One type of hyperemia is the 'Active Hyperemia', which is also called the 'exercise hyperemia' or the 'functional hyperemia'. It usually occurs when the muscles in your body contracts, which may occur due to various reasons such as increase in mental, gastrointestinal or cardiac activities. The active hyperemia occurs due to the combination of hypoxia tissues and also the production of vasodilator metabolites. In the former, the oxygen supply to the blood vessel tissues, is less. Thus, these tissues now start demanding for more oxygen, and this in turn leads to vasodilation. In the case of the latter, widening of the blood vessels takes place due to the relaxing of the smooth muscles which are found inside the blood vessel walls. Substances called vasodilators, such as potassium ion, nitric oxide, carbon dioxide and adenosine, usually triggers this process. Seconds after the increasing of tissue metabolism, active hyperemia becomes evident. The increase in tissue metabolism, also increases the blood flow, which returns to normal only after the metabolism is restored to normal.

Another hyperemia cause is the blockage of veins. When this happens, it is called the 'Reactive Hyperemia'. It is also called 'passive hyperemia'. Here, the blood collects in certain organs of the body as the veins are blocked. Hence, blood cannot flow freely. Usually a person who just had an episode of ischemia, gets the reactive hyperemia. Due to this, the oxygen level in the blood is reduced and the metabolic waste level goes up. This waste may also start collecting in any organ, which in turn might block the flow of the blood. You probably might have noticed a red mark on your body after you remove a tight band placed around your hand or leg. That is a result of reactive hyperemia. If a person has undergone occlusions, then this type of hyperemia might occur. This hyperemia becomes severe, the longer one person experiences coronary occlusions, and the longer will it last.

Treatment

If you are wondering that if the red marks that you have, are hyperemia or not, then you must also be worrying about whether or not you can cure it. Hyperemia is a curable. If proper medical attention is given, then it can be cured properly. Of course, the treatments depend upon the type of hyperemia you have; active or reactive. If you ignore hyperemia, then it will be harmful for you. Do not think that like some other diseases even hyperemia will heal on its own. So, if the doctors say that you have this disease, then you have to consult them daily. And always get it treated from good doctor. Do not be 'penny wise, pound foolish'. Also, if you have any questions regarding this disease, then do not hesitate to ask the doctor. If given the proper medical attention, hyperemia is curable.

If you are showing any of the hyperemia symptoms, go to a doctor immediately.
