Hi.. Can understand your concern.. As per your complain sunken eyes, temples and cheeks occurs as a result of loss of fat from the cheeks as well as peri orbital region that is around the eyes giving it a sunken look as well as malnutrition also plays a role in this case and a new name is being proposed for it known as Areca Nut Chewer Syndrome.. The first thing that you have to do as the biggest remedy is to STOP CHEWING TOBACCO as it can also lead to ORAL CANCER.. Tobacco cessation followed by intake of nutritious food and multivitamins tablet one daily can help in regaining the fat to some extent although complete recovery is questionable.. I would suggest you to consult a dentist and get evaluated and get a check up done of the Oral cavity too to rule out for the level of mouth opening as well as any abnormity in the mucosa of mouth.. Once you quit tobacco you should consult a dietician and get a proper diet plan so that you get proper diet plan for regaining the lost fat and nutrition.. Taking multivitaminsand antioxidants daily for a month or two can help in recovering from the nutritional deficiencies. A sufficient workout and physiotherapy to regain the loss musculature and fat of face can be done.. Hope this information helps.. Thanks and regards.. Dr.Honey Nandwani Arora..
