Vitamin deficiency is a condition caused by a lack of vitamins and can manifest itself in various ways: from mild fatigue to serious health disorders. Early recognition of the deficiency helps to avoid complications and restore energy to everyday life.
What to look out for
The most common signs of vitamin deficiency are constant fatigue and weakness (often with a deficiency of B vitamins and iron), skin and hair problems (dryness, peeling, loss - with a lack of A, E, biotin), frequent colds (may indicate a deficiency of C or D), problems with night vision or dry eyes (A), as well as bone pain and brittle nails - typical of a lack of D and calcium.
Why does avitaminosis occur?
The reasons are an unhealthy diet with a predominance of fast food and a lack of vegetables and fruits, increased body needs during pregnancy, stress or intense training, malabsorption in the gastrointestinal tract (diseases, medications, alcoholism), and seasonal factors - for example, in winter, vitamin D levels often decrease due to a lack of sunlight.
How to prevent and what to do
The best prevention is a varied diet: vegetables, fruits, fish, dairy products, nuts, whole grains. During seasonal periods or when there is an increased need, supplements (D, C or multivitamins) are advisable, but they should be taken after consulting a doctor. Regular blood tests help detect deficiencies in the early stages. Don't forget about your lifestyle: sufficient sleep, moderate physical activity and stress reduction improve the absorption of nutrients.
When to see a doctor
If symptoms progress (severe fatigue, frequent infections, sudden weight loss, serious skin or vision problems), be sure to consult a specialist - only a doctor can prescribe the necessary tests and dietary correction or treatment. Vitamin deficiency is a signal to the body that it needs care; simple changes in diet and regimen often solve the problem, but sometimes medical intervention is required.
