;Dermatologist Rinky Kapoor cautions, “If your finger tips turn blue or are extremely pale, this is a sign of low oxygen in the blood,” a condition which is called cyanosis.Some people experience this when they travelto high altitudes or to low-temperature regions, but if you notice blue colouration even at normal temperatures, then it couldbe a more serious issue. Heart and lung related diseases could cause blue fingertips. Infect, it has been noticed that kids born with heart malfunctions have blue fingertips since birth. It could also be an indicator of diseases like scleroderma, arthritis, and Raynaud’s disease,”adds Kapoor
