Vitamin C deficiency and scurvy
A severe lack of vitamin C can lead to scurvy. We may think of it as a disease of the past, but it does still exist. Factors or lifestyle issues that may increase your scurvy risk include:
regularly eating unhealthy foods
crash dieting – especially being on diets that exclude certain food groups
being malnourished due to inadequate care
very strict allergy diets
having an eating disorder
smoking – smokers need more vitamin C to cope with the extra stress on their body
