Skin itching can be caused by various factors, including vitamin deficiencies. Vitamin A and vitamin B12 deficiencies are known to cause itchy skin without a rash.
- Vitamin A deficiency can lead to dry, itchy skin, and in severe cases, it may even cause night blindness and impaired immune function.
- Vitamin B12 deficiency can also cause itchy skin and other symptoms like fatigue, weakness, and numbness.
However, it's important to note that itchy skin can be a symptom of many other conditions, including:
- Dry skin
- Eczema
- Contact dermatitis
- Allergic reactions
- Iron deficiency anemia
- Certain medications
- Pregnancy
- Liver disease
- Kidney disease
It's best to consult a doctor for advice if you experience persistent or severe itching. They can identify the underlying cause and recommend appropriate treatment.
