Dear Ms. Shanmugaraj, Thank you for answering me my questions about my daughters health. Sometimes my daughters outer corners of the mouth become dry and sometimes bleed due to her scratching. Why is it so, Please help. Mrs. Zeeba Kanpur   Hello Ms.Zeba, Thank you for getting in touch with us, once again. From what you have described about Adeeba, it looks like she may have 'angular stomatitis'. This condition could have arisen due to a deficiency of any one or more of the following vitamins: Riboflavin, Folate and/or Vitamin B12. (These are all B-complex vitamins). Regularly including whole grains, lentils & green leafy vegetables ensures an adequate supply of these vitamins. Having said that, I would request you to first get your physician's opinion to be doubly sure. Till then, make sure Adeeba's nails are clipped often to prevent the damage from scratching. Best wishes, Padmashri Shanmugaraj Online dietician www.NutritionVista.com India
