Vitamins are essential nutrients that your body needs in small amounts to function properly. When you don’t get enough of one or more vitamins—either from your diet or due to absorption issues—you may begin to experience vitamin deficiency. Early symptoms can be subtle but may lead to serious health problems if ignored.
Why Vitamin Deficiencies Happen
Deficiencies can be caused by:
- Poor or unbalanced diet
- Chronic diseases (like digestive or liver disorders)
- Alcohol or drug abuse
- Pregnancy or breastfeeding
- Aging
- Certain medications
- Vegan or restrictive diets without supplementation
Understanding the symptoms of different deficiencies can help detect and treat them early.

Preventing Vitamin Deficiency
