Introduction
Noticing red dots on your skin can be alarming, especially if they appear suddenly or start to spread. These red spots can vary in size, shape, and intensity, and they may be harmless or a sign of an underlying health condition. While some red dots disappear on their own, others may require medical attention. Understanding the possible causes can help you determine whether they are benign or a reason for concern.
In this article, we explore the most common causes of red dots on the skin, what they mean, and when to seek medical advice.
1. Petechiae: Tiny Red or Purple Dots
What It Means
Petechiae are tiny, pinpoint-sized red or purple spots that appear due to broken blood vessels (capillaries) under the skin. They do not fade when you press on them and often appear in clusters.
Possible Causes
- Infections (e.g., strep throat, viral infections)
- Vitamin deficiencies (especially Vitamin C and Vitamin K)
- Blood disorders (low platelet count, leukemia)
- Side effects of medications (such as blood thinners or chemotherapy drugs)
- Excessive straining (from coughing, vomiting, or lifting heavy objects)
When to Seek Help
If petechiae appear suddenly, spread rapidly, or are accompanied by fever, bruising, or unusual bleeding, seek medical attention immediately.
