Not getting enough vitamins in your diet can lead to a range of health problems, known as vitamin deficiency diseases. These issues develop slowly over time and can affect everything from your energy levels to your bones, skin, and immune system. For example, vitamin C deficiency causes scurvy (bleeding gums, poor wound healing), while vitamin D deficiency causes rickets (soft, bowed bones). Globally, nearly 2 billion people are at risk of micronutrient deficiencies. Below, we explore what deficiency diseases are and how a vitamin and deficiency diseases chart can help you recognize and prevent these conditions.
What are Deficiency Diseases?
Deficiency diseases are health problems that arise when the body doesn’t get enough of a specific nutrient over time. In other words, an imbalanced diet can lead to insufficient intake of certain vitamins or minerals, causing deficiency diseases . Common examples include scurvy (from vitamin C lack), rickets (vitamin D), and goiter (iodine deficiency). Each condition is tied to missing nutrients; for instance, night blindness is a deficiency disease caused by a vitamin A shortage. A deficiency disease, like anemia, can result from a lack of iron or vitamin B12.
-
Scurvy – from vitamin C deficiency; leads to bleeding gums, bruising, and fatigue.
-
Rickets/Osteomalacia – from vitamin D deficiency; causes soft, weak bones (bowed legs in children).
-
Beriberi – from vitamin B1 (thiamine) deficiency; causes nerve and heart problems.
-
Pellagra – from niacin (vitamin B3) deficiency; causes diarrhea, dermatitis, and dementia.
-
Xerophthalmia/Night blindness – from vitamin A deficiency; causes severe vision problems.
-
Anemia – often from vitamin B12 or iron deficiency; causes fatigue and weakness.
-
Goiter – from iodine deficiency; causes an enlarged thyroid gland.
To clarify these relationships, below is a deficiency diseases chart listing key nutrients, the diseases caused by their lack, and foods rich in those nutrients:

What are Vitamin Deficiency Diseases?
Vitamin deficiency diseases are deficiency diseases caused specifically by a lack of vitamins. Each vitamin has its own set of associated deficiency conditions. Understanding the types of vitamins and their deficiency diseases can help you recognize symptoms early. For example:
-
Vitamin A – Deficiency causes night blindness (xerophthalmia) and immune problems.
-
Vitamin C – Deficiency causes scurvy (bleeding gums, fatigue, poor wound healing).
-
Vitamin D – Deficiency causes rickets (bone deformities in children) and osteomalacia in adults.
-
Vitamin B1 (Thiamine) – Deficiency causes beriberi (nerve degeneration, heart issues).
-
Niacin (Vitamin B3) – Deficiency causes pellagra (dermatitis, diarrhea, dementia).
-
Vitamin B12 – Deficiency causes pernicious anemia and neurological symptoms (fatigue, numbness).
-
Vitamin K – Deficiency can cause excessive bleeding (hemorrhage).
In each case, the disease name reflects the missing vitamin. For example, pellagra is a vitamin B3 (niacin) deficiency disease. When studying vitamins and their deficiencies, it’s helpful to use a chart of vitamins and their deficiency diseases.
Such charts list vitamins' names and diseases they prevent, making it easy to spot connections (e.g., “Vitamin C – Scurvy”, “Vitamin D – Rickets”). A vitamin deficiency chart or vitamins chart with deficiency diseases therefore becomes a powerful learning tool for health-conscious adults.
How to Prevent Deficiency Diseases
Preventing deficiency diseases is largely about diet and lifestyle. Experts agree that food first is the best strategy. Key prevention steps include:
-
Eat a varied, balanced diet. Include colorful fruits and vegetables, whole grains, lean proteins, and healthy fats. “It is best to get vitamins and minerals from eating a variety of healthy unprocessed foods”. A mix of different foods ensures you cover all vitamins and their deficiencies naturally.
-
Use fortified foods when needed. Many staple foods (like milk, cereals, and salt) are fortified with vitamins/minerals. For example, iodized salt prevents goiter, and fortified dairy or cereals provide extra vitamin D and B vitamins.
-
Consider supplements judiciously. Some people need supplements (e.g., B12 for vegans, vitamin D in winter) as a safety net. However, supplements should complement a good diet, not replace it. Jacked Nutrition’s high-quality multivitamins can help fill gaps for at-risk individuals.
-
Get enough sunlight. Safe sun exposure helps your body make vitamin D. If you live in a cloudy climate or use sunblock, consider vitamin D-rich foods or supplements.
-
Regular check-ups. If you have symptoms (fatigue, weakness, hair loss, etc.), see a doctor. Blood tests can detect low nutrient levels before a full-blown deficiency disease develops. Catching issues early makes prevention easy.
-
Address underlying issues. Digestive disorders (like celiac or Crohn’s disease) or surgeries can impair nutrient absorption. If you have such conditions, work with a healthcare provider to monitor vitamin status and consider supplements as directed.
By focusing on nutrient-rich foods and healthy habits, you can avoid deficiency diseases charted here. A vitamins and deficiency diseases chart can guide meal planning: for example, adding citrus fruits and red peppers to your plate covers vitamin C, while dairy or fortified plant milk covers calcium and vitamin D. Remember, supplements are supplements, not magic cures – a balanced diet is your best prevention.

FAQs
What is Vitamin C beneficial for?
Vitamin C (ascorbic acid) is a powerful antioxidant important for many functions. It supports the immune system, helps produce collagen (for skin, blood vessels, and bones), and improves iron absorption from plant foods. Getting enough vitamin C (from citrus fruits, berries, peppers, etc.) helps prevent scurvy and boosts overall health.
What are 10 diseases caused by vitamin deficiency?
Ten classic deficiency diseases include:
-
Scurvy (vitamin C deficiency): bleeding gums, bruising.
-
Rickets (vitamin D deficiency): bone deformities in children.
-
Beriberi (vitamin B1 deficiency): nerve damage and heart issues.
-
Pellagra (niacin/Vitamin B3 deficiency): dermatitis, diarrhea, dementia.
-
Xerophthalmia/Night Blindness (vitamin A deficiency): vision loss.
-
Pernicious Anemia (vitamin B12 deficiency): fatigue, nerve problems.
-
Megaloblastic Anemia (folate/folic acid deficiency): weakness, birth defects.
-
Goiter/Cretinism (iodine deficiency): thyroid enlargement, developmental issues.
-
Bleeding Disorders (vitamin K deficiency): excessive bleeding.
-
Osteoporosis/Osteomalacia (severe calcium or vitamin D deficiency): brittle bones.
What causes vitamin deficiency?
The main causes are poor diet or poor absorption. A diet lacking variety (e.g. few fruits/vegetables or animal products) can cause vitamin shortages. Digestive issues also play a role: intestinal diseases (celiac, Crohn’s) or surgeries (gastric bypass) can limit the absorption of vitamins like B12.
Certain medications, alcohol abuse, and smoking can deplete vitamins or hinder their uptake. Insufficient intake or impaired absorption leads to deficiency diseases, so addressing diet and health conditions is key.
What causes B12 deficiency?
Vitamin B12 deficiency often stems from impaired absorption. The stomach normally makes a protein (intrinsic factor) needed for B12 uptake; conditions like pernicious anemia (autoimmune) can block this. Also, gastrointestinal surgeries that remove part of the stomach or small intestine can cause B12 malabsorption.
Diet plays a role too: B12 is found in animal foods, so strict vegans who don’t supplement can become deficient. B12 deficiency is caused by either not getting enough (dietary lack) or not absorbing enough (stomach/intestine issues).
