Scurvy, a disease caused by not eating enough vitamin C, is making a comeback in children, even in wealthy countries like Italy. Researchers studied eight children with scurvy and reviewed 253 cases from medical literature to understand why this old disease is returning. The study found that children with scurvy suffer from bleeding gums, poor wound healing, weak bones, and joint pain. Many cases happened because parents avoided giving their kids citrus fruits like oranges and lemons due to old myths about them causing health problems. This research warns doctors and parents that scurvy is still a real threat and shows how to spot it early.
The Quick Take
- What they studied: Why scurvy (a vitamin C deficiency disease) is appearing in children in modern, wealthy countries and what signs doctors should look for
- Who participated: Eight children treated at two hospitals in Italy between 2021-2023, plus a review of 253 other scurvy cases from medical studies worldwide
- Key finding: Scurvy is still occurring in developed countries, often because parents avoid giving children citrus fruits based on false beliefs that these fruits cause urinary tract infections or are toxic when mixed with milk
- What it means for you: Parents and doctors should know that scurvy can happen today, especially in children with poor diets or certain health conditions. If a child has bleeding gums, joint pain, or slow-healing wounds, vitamin C deficiency should be considered. However, this is still rare in well-fed children with normal diets.
The Research Details
This research combined two approaches: first, doctors documented eight real cases of scurvy they treated in Italian hospitals over two years, carefully recording each child’s symptoms and how they were diagnosed. Second, the researchers searched through 126 medical articles published worldwide and found 253 other documented cases of scurvy to understand patterns and common causes.
The researchers looked at information like the children’s ages, whether they were boys or girls, what symptoms they had, and whether they had any learning or developmental problems. They also reviewed what vitamin C does in the body and why it’s so important for health.
This approach—combining real patient cases with a broad review of existing research—helps doctors understand both the specific details of individual cases and the bigger picture of how common scurvy is and who is most at risk.
By studying actual cases and reviewing all available research, doctors can learn to recognize scurvy faster and treat it before it causes serious damage. This matters because scurvy can be completely prevented and cured with proper nutrition, but only if doctors know to look for it. The research also helps explain why scurvy is appearing in wealthy countries where people should have access to healthy food.
This study is a case report combined with a literature review, which is a solid way to understand rare diseases. The researchers examined 261 total cases (8 new plus 253 from literature), giving them good information about patterns. However, because scurvy is rare, the sample size is small. The study relies on cases that were already documented, so some information might be incomplete. The research was published in a peer-reviewed medical journal, meaning other experts checked the work. This type of study is good for raising awareness about a disease but cannot prove cause-and-effect relationships.
What the Results Show
The eight children studied in Italy showed common signs of scurvy: bleeding and swollen gums, poor healing of cuts and scrapes, joint and muscle pain, and weak or brittle nails. Some children also had anemia (low red blood cells), which happens because vitamin C helps the body absorb iron. The children ranged in age and came from different backgrounds, but many had limited diets or certain health conditions that made them eat poorly.
When doctors gave these children vitamin C supplements or improved their diets with vitamin C-rich foods, their symptoms improved significantly. This confirmed that vitamin C deficiency was causing their problems. The review of 253 other cases worldwide showed similar patterns—children with scurvy had bleeding gums, slow wound healing, and joint pain as their main complaints.
An important finding was that many cases in Italy appeared to be linked to parents’ false beliefs about citrus fruits. Some parents thought oranges and lemons would cause urinary tract infections in their children or would be poisonous if mixed with milk, so they avoided giving these foods to their kids. This cultural myth led to vitamin C deficiency in otherwise well-fed families.
Beyond the main symptoms, some children with scurvy had additional problems including anemia, high blood pressure in the lungs, and developmental delays. A few children had neurological issues (problems with the nervous system), suggesting that severe vitamin C deficiency can affect brain development. The research showed that children with other health conditions—like digestive problems or learning disabilities—were at higher risk for developing scurvy, possibly because these conditions made it harder for them to eat well or absorb nutrients properly.
Scurvy was thought to be a disease of the past, mainly seen in sailors and people living in poverty without access to fresh food. This new research shows that scurvy is still occurring in modern times, even in wealthy countries with good food availability. Previous studies had documented scurvy mostly in developing countries or in specific groups like elderly people or those with severe malnutrition. This study is important because it shows that scurvy can happen in children in rich countries, often due to dietary choices or false health beliefs rather than lack of food access.
This study has several important limitations to understand. First, it’s based on cases that were already documented, so the researchers couldn’t control how information was collected or what details were recorded. Second, the study is small (only eight new cases), so the findings may not apply to all children with scurvy. Third, because scurvy is rare, the researchers couldn’t compare it to a control group of healthy children. Fourth, the study focuses on cases in Italy and from published literature, which may not represent all cases worldwide—some cases might not be reported or published. Finally, while the research suggests that false beliefs about citrus fruits contributed to scurvy in Italy, this was not scientifically proven, just observed by the doctors.
The Bottom Line
Parents should ensure children eat vitamin C-rich foods regularly, including citrus fruits (oranges, lemons, limes), berries, kiwis, tomatoes, and leafy greens. These foods are safe and beneficial—the old myths about citrus fruits causing harm are false. If a child shows signs of scurvy (bleeding gums, joint pain, slow-healing wounds, or unusual bruising), parents should contact a doctor immediately. Doctors should consider vitamin C deficiency in children with these symptoms, especially those with limited diets or certain health conditions. Vitamin C supplements are safe and effective treatment when needed. Confidence level: High for prevention through diet, moderate for treatment recommendations (based on case reports rather than large clinical trials).
Parents of young children should care about this research, especially those who restrict their children’s diets or follow unusual dietary practices. Doctors and pediatricians should be aware that scurvy can occur in their communities and know how to recognize it. Children at higher risk include those with digestive problems, developmental delays, or very limited diets. This research is less relevant for families who eat balanced diets with regular fruits and vegetables. Healthy children eating normal diets have very low risk of scurvy.
Vitamin C deficiency symptoms develop gradually over weeks to months of inadequate intake. Once a child starts eating vitamin C-rich foods or takes supplements, symptoms typically improve within days to weeks. Bleeding gums may take 1-2 weeks to improve, while joint pain and weakness may take 2-4 weeks. Complete recovery usually happens within 1-2 months of proper treatment. Prevention is much easier than treatment—eating vitamin C daily prevents scurvy from developing at all.
Want to Apply This Research?
- Track daily vitamin C intake by logging servings of citrus fruits, berries, tomatoes, and leafy greens. Set a goal of at least one vitamin C-rich food per day. Users can photograph meals or check off food items consumed.
- Use the app to set reminders to include one vitamin C-rich food at each meal. Create a shopping list of affordable vitamin C sources (oranges, apples, frozen berries, canned tomatoes). For children, gamify the experience by earning points for trying new fruits or vegetables.
- Track symptoms that might indicate vitamin C deficiency: gum health, wound healing speed, joint pain, and energy levels. Monitor weekly and alert users if they notice concerning changes. For families with dietary restrictions, use the app to ensure adequate vitamin C alternatives are included and to educate about safe, nutritious foods.
This research describes scurvy cases and general information about vitamin C. It is not medical advice for diagnosing or treating individual children. If your child shows signs of scurvy (bleeding gums, joint pain, slow-healing wounds, unusual bruising, or weakness), contact a pediatrician or healthcare provider immediately for proper evaluation and treatment. Do not attempt to diagnose or treat scurvy without professional medical guidance. While vitamin C-rich foods are safe and recommended for all children, individual nutritional needs vary. Consult with a healthcare provider about your child’s specific dietary needs, especially if your child has health conditions, takes medications, or follows restricted diets.
