Doctors Near You for Petechia in Queimados

Petechiae are small, pinpoint red, purple, or brown spots that appear on the skin, mucous membranes, or inside the mouth and eyes due to minor bleeding from broken capillaries or blood vessels. These spots are typically less than 2 millimeters in diameter and do not blanch or turn white when pressed. Petechiae can appear anywhere on the body and often occur in clusters, giving the skin a rash-like appearance. Unlike bruises, petechiae are not caused by trauma or injury but rather by bleeding under the skin, which can indicate a range of medical conditions. The causes of petechiae are varied and can range from minor to serious. Common causes include physical strain such as coughing, vomiting, or crying, which can increase pressure on the capillaries and cause them to burst. Petechiae can also be a side effect of certain medications, such as blood thinners, antibiotics, or chemotherapy drugs. More serious causes include infections, such as viral or bacterial infections that lead to blood vessel inflammation (vasculitis), or conditions affecting blood clotting, such as thrombocytopenia (low platelet count), leukemia, or other blood disorders. Petechiae may also occur due to underlying autoimmune diseases, like lupus, that affect blood vessel integrity. In rare cases, petechiae can be a sign of a life-threatening condition like meningitis or sepsis, which requires immediate medical attention. Treatment for petechiae depends on the underlying cause. If petechiae are due to physical strain or a minor injury, they often resolve on their own without treatment. When petechiae are caused by an underlying medical condition or infection, treating that condition is the priority. This may involve antibiotics for bacterial infections, medications to manage autoimmune diseases, or treatment to increase platelet count in blood disorders. If petechiae are a side effect of medication, adjusting or discontinuing the medication under a doctor's guidance may be necessary. Monitoring for additional symptoms, such as fever, headache, or changes in consciousness, is crucial, as these can indicate a more serious condition requiring urgent care.
