3. Liver disease – a hidden warning sign
The liver is involved in blood clotting. When its function is impaired, blood vessels become fragile and spider angiomas and palmar erythema (red palms) appear.
Additional symptoms:
-
Yellowing of the skin (jaundice)
-
Swelling of the legs or abdomen
-
Fatigue and nausea
If you have risk factors (alcohol, hepatitis, fatty liver), do not ignore skin changes.
4. Vitamin deficiency
-
Vitamin C (scurvy) – rare today, but possible with a very poor diet
-
Vitamin K – more common in people with bowel disease or on blood thinners
Both of these deficiencies weaken the vessel walls and lead to petechiae.
5. Physical exertion or trauma
Severe coughing, vomiting, lifting heavy loads, or wearing tight clothing can cause temporary pimples. They usually go away on their own, but if they persist, consult a specialist.
6. Autoimmune or inflammatory diseases
-
Lupus
-
Rheumatoid arthritis
-
Vasculitis (inflammation of blood vessels)
They often cause rashes, petechiae, or purpura.
When to see a doctor?
Don’t panic, but do react if you notice:
✅Spots that do not disappear under pressure
✅Rapid spreading
✅Unexplained bruising along the spots
✅Fever, fatigue, or joint pain
✅Personal history of liver, blood, or autoimmune disease
A simple blood test or examination by a dermatologist is often enough to determine the cause.
How do doctors make a diagnosis?
-
Physical examination of spots
-
Complete blood count (CBC) for platelet count
-
Liver tests and vitamin levels
-
Looking for an infection or autoimmune process
In most cases, the cause is treatable, but early diagnosis is crucial.
