Red spots on skin: when a deficiency is only one possible explanation

Scurvy is a specific nutritional disorder

ODS describes impaired collagen formation and petechiae in severe vitamin C deficiency. The assessment depends on diet, other symptoms and clinical findings. Ordinary red marks alone do not establish scurvy or show which supplement to take. [1]

Bleeding spots have other causes

MedlinePlus distinguishes petechiae and purpura from ordinary skin redness and lists causes including injury, infections, platelet problems and medicines affecting clotting. A home observation that a mark does not blanch cannot determine its cause or rule out a serious illness. [2]

Investigate unexplained sudden spots

Imagine small red-purple spots appear without injury. Contact a clinician about unexplained bleeding into skin rather than waiting to see whether vitamin C clears it. Bring medicines, supplements and recent illness details to the assessment, particularly if there are other bleeding symptoms. [2]

Hypothetical example — match the action to the actual concern
Concern	Useful distinction
Severe C deficiency	One possible cause of petechiae
Red mark	Not a nutrient-specific diagnosis
Unexplained bleeding spots	Requires clinical assessment
