Outline 5 indications of vitamin A?

1. Night blindness: Vitamin A deficiency can lead to difficulty seeing in low light conditions, known as night blindness.

2. Dry, rough skin: Vitamin A plays a key role in maintaining healthy skin, and a deficiency can result in dry, rough skin and poor wound healing.

3. Increased susceptibility to infections: Vitamin A is important for maintaining a healthy immune system, so a deficiency can lead to an increased susceptibility to infections.

4. Poor growth and development: Vitamin A is essential for normal growth and development, so a deficiency can result in stunted growth and delayed development in children.

5. Xerophthalmia: Severe vitamin A deficiency can lead to a condition called xerophthalmia, which is characterized by dryness of the eyes, corneal ulcers, and eventually blindness if left untreated.

1. Night blindness: Difficulty seeing in dim light due to insufficient rhodopsin, a protein in the retina that relies on vitamin A.

2. Dry eyes: Impaired tear production due to vitamin A's role in maintaining the health of the tear glands and epithelial cells.

3. Bitot's spots: Whitish, foamy deposits on the conjunctiva due to accumulation of keratinized cells, a symptom of severe vitamin A deficiency.

4. Corneal ulceration: Damage to the cornea, the clear outer layer of the eye, due to impaired epithelial cell growth and function.

5. Impaired immune function: Vitamin A is essential for the production and function of T cells, essential components of the immune system.
