Little flesh coloured bumps, called skin tags, can show up on the neck, shoulders and where there is skin irritation or friction, like under necklace, straps or waistband. Research has shown that these are an early warning sign of blood sugar imbalances.
If a skin tag is twisted on its blood supply it may turn red or black. Skin tags may bleed if caught on clothing or are otherwise torn. Skin tags are not painful and are not associated with any particular skin conditions or symptoms.
Skin tags are not present at birth and their frequency increases with age. Skin tags can be observed in about 25% of adults and so are quite common. Studies have shown a genetic predisposition to the development of skin tags. Therefore, skin tags can run in families.
