<bot>: Hi there. Welcome to Chat Doctor. I have read your query. It appears that your father may be suffering from possible Vitamin deficiency like Riboflavin and other B vitamins and possibly vitamin A. It is advisable to eat plenty of fresh fruits and green leafy vegetables. The colors fruits and vegetables have more vitamin content than the non-coloured ones. Also in old age, the person tends to not take enough water so high chance of deny Chat Doctor.  Kindly make sure he is well HY
