Hyperemia is the increase in blood supply to the organs, and the accumulation of blood in the tissue or organ. There are 2 different types called active hyperemia and passive hyperemia. Causes of hyperemia include exercise, high fever, menopause, injury, infection, heart failure, and thrombosis.
What is Hyperemia?
Hyperemia is defined as blood vessels in a certain area filling with more blood than normal.
Causes of hyperemia vary according to passive and active.
What Does Hyperemic Edema Mean?
This concept is often associated with stomach ailments. Hyperemic edema can be diagnosed with the examinations performed in the internal diseases (internal medicine) branch.
Hyperemic means blood accumulation in medicine. Hyperemic edema is the formation of edema due to blood accumulation in a certain place.
Causes of edema may differ. However, in any case, a fluid increase can be mentioned. Blood also mixes with these fluids, causing edema. The diagnosis received by patients with this condition is usually stomach inflammation. The aforementioned ailment is within the area of interest of the gastroenterology unit.
What is Active Hyperemia?
Increased blood circulation to a limb is called active hyperemia. Blood vessels dilate and try to get more blood in. Some of the factors that can cause this are:
To exercise: Exercise is one of the active hyperemia causes. Our muscles and heart need more oxygen during exercise. Our blood loads on the organs in order to increase the amount of oxygen.
High fever: Body As a result of the increase in body temperature, more blood starts to flow to our skin. This is a reflection that the body creates to lower the temperature.
Temperature: If the environment we are in is hot or if we have a fever, there will be extra blood flow to our skin. Thus, our body allows the release of heat.
Digestion: After consuming food, our stomach and intestines take action to break down what we eat and make them usable. However, intensive blood flow is needed for digestion and nutrient absorption.
Redness and Hot Flashes on the Skin: Before menopause, during perimenopause, the body is in preparation to end the menstruation process. During this time period, complaints of hot flashes may be encountered while hormone levels go up and down. Blood goes to the skin layer above normal. The rash produces a similar effect.
Inflammation: It is possible to say that blood flow increases in cases such as infection and injury. The body sends blood to that area to fight infection and treat the wound. This can cause active hyperemia.
What is Passive Hyperemia?
Sometimes, blood flow cannot flow comfortably from one limb to another. This results in the accumulation of blood in the blood vessels. This is called passive hyperemia (congestion).
Passive hyperemia is the accumulation of blood that cannot be pumped into the body in a tissue or organ, often as a result of a condition that causes a blockage in a vein or artery. The causes of passive hyperemia are as follows:
Thrombosis: It is the occurrence of a clot in an artery or vein. The clot interferes with the flow of blood and therefore accumulates blood on one side of the body.
Heart failure: What causes passive hyperemia? Another answer to the question is heart failure. This prevents the heart from pumping blood around the body. There may be blood accumulation in the lungs, spleen, kidneys, and liver, and congestion may occur. If left untreated, it can cause serious complications.
What are the Symptoms of Hyperemia?
- Weight gain
- Warmth and redness of the skin
- Shortness of breath
- Feeling lethargic, tired
How Is Hyperemia Treated?
Hyperemia treatment is planned according to the cause. Treatment alternatives are related to active hyperemia or passive hyperemia. Active hyperemia caused by heat, exercise and digestion does not require treatment. When the person relieves the feeling of heat, stops exercising, and the digestive activity is completed, the blood flow will return to normal.
However, passive hyperemia due to other reasons will not resolve on its own without medical intervention.
Drugs used in the treatment of hypemia are as follows:
- Blood thinners
- Beta blockers (for the purpose of lowering blood pressure)
- Digoxin (To improve heart rate)
Passive causes of hypemia can be eliminated. When the factors that cause this (diabetes, high blood pressure, etc.) are taken under control, excessive blood accumulation will pass, and the circulation in that area will continue in a healthy way.
