6. Blood Vessel Disorders: Red Dots That Don’t Fade
What It Means
Some red spots are caused by abnormalities in blood vessels, leading to permanent red dots or patches on the skin.
Possible Causes
- Spider angiomas (small, red, spider-like blood vessel clusters)
- Hemangiomas (benign growths of blood vessels, common in infants)
- Vasculitis (inflammation of blood vessels, often linked to autoimmune diseases)
When to Seek Help
If red dots appear suddenly, grow in size, or are accompanied by pain or other unusual symptoms, a doctor’s evaluation is necessary.
7. Autoimmune Disorders: Persistent Red Spots
What It Means
Some autoimmune diseases can cause red spots, rashes, or skin inflammation. These conditions occur when the immune system attacks healthy skin cells.
Possible Causes
- Lupus (butterfly-shaped rash on the face)
- Psoriasis (red, scaly patches)
- Dermatomyositis (red or purple rashes, often on the knuckles or face)
When to Seek Help
If red spots are accompanied by joint pain, fatigue, or other systemic symptoms, consult a doctor for further evaluation.
8. Fungal or Bacterial Infections
What It Means
Some infections can cause red spots, swelling, and irritation. These infections may spread if left untreated.
Possible Causes
- Ringworm (fungal infection with red, circular rashes)
- Impetigo (bacterial skin infection causing red sores with yellow crusts)
- Meningitis rash (serious bacterial infection causing red or purple spots that do not fade when pressed)
When to Seek Help
Seek immediate medical attention if red spots spread quickly, become painful, or are accompanied by fever.
