Red dots on the skin, also known as petechiae, are a common occurrence that can appear suddenly. They can be concerning because they may look alarming, but they can have a variety of causes, ranging from harmless to more serious underlying conditions. Understanding the causes and potential implications of red dots on your skin is essential for taking the right steps in seeking treatment or alleviating concerns.
What Are Red Dots on the Skin?
Red dots on the skin are typically small, pinpoint-sized spots that appear due to broken blood vessels just beneath the surface of the skin. These spots can vary in color from bright red to purple and may even appear to be darker as they age. In most cases, they are harmless and may disappear on their own. However, sometimes they can be indicative of a more serious medical issue that requires attention.
1. Petechiae
Petechiae are small, red or purple dots that form when small blood vessels under the skin break. These dots are typically less than 2 millimeters in size and can occur anywhere on the body, but they are most common on the upper body and the legs. Petechiae are often a sign of a problem with blood clotting or pressure changes, and they may be associated with:
• Straining or excessive coughing: Intense coughing or straining can cause small blood vessels to break, leading to red dots.
• Infections: Viral or bacterial infections like strep throat, meningitis, or septicemia can result in petechiae.
• Medications: Blood thinners, aspirin, or certain antibiotics can increase the risk of petechiae formation.
• Platelet Disorders: Conditions like thrombocytopenia, where you have low platelet levels, can make you more prone to developing petechiae.
