Hyperaemia
(Redirected from Reactive hyperemia)
Hyperaemia is a medical condition characterized by an increased blood flow in the body. This can occur in any part of the body and is often a response to inflammation or infection. Hyperaemia can be either active, resulting from arterial dilation, or passive, resulting from venous obstruction or decreased tonus.
Causes[edit | edit source]
Hyperaemia can be caused by a variety of factors, including:
- Inflammation: This is the body's response to injury or infection, and it often results in increased blood flow to the affected area.
- Infection: Certain infections can cause hyperaemia as the body tries to fight off the invading pathogens.
- Exercise: Physical activity can increase blood flow to the muscles, resulting in hyperaemia.
- Heat: Exposure to heat can cause the blood vessels to dilate, leading to hyperaemia.
Symptoms[edit | edit source]
The symptoms of hyperaemia can vary depending on the cause and the area of the body affected. They may include:
- Redness: This is often the most noticeable symptom of hyperaemia. The affected area may appear red due to the increased blood flow.
- Swelling: In some cases, hyperaemia can cause swelling in the affected area.
- Pain: Hyperaemia can sometimes cause pain, especially if it is caused by inflammation or infection.
- Warmth: The affected area may feel warm to the touch due to the increased blood flow.
Treatment[edit | edit source]
Treatment for hyperaemia typically involves addressing the underlying cause. This may include:
- Anti-inflammatory drugs: These can help reduce inflammation and thus decrease hyperaemia.
- Antibiotics: If an infection is causing the hyperaemia, antibiotics may be prescribed to fight off the infection.
- Rest: In some cases, simply resting the affected area can help reduce hyperaemia.
