Hello A Detailed clinical examination is necessary to rule out the main cause for ulcers There are many reasons for ulcers like nutritional deficiencies, hormonal, imbalances, gastrointestinal reasons or genetic

Their is no specific reason for ulcers..visit your dentist to rule out the cause..in the meantime take multivitamins ,take lots of water..and may be due to hormonal disturbance..that the dentist will advise you once you get your clinical checkup..

Oral ulcers are a common occurrence with GI disturbances ,which appears clearly true in your case . Please consult another GI specialist if the previous one you visited was not of much help. The pic of tests is not very clear but if Vit B12 is normal, advised to get serum iron, folate ferritin ,CBC if not already checked. Since you have visited Dentist already ,i am assuming sharp edges of teeth have been ruled out ,but if not ,worth while mentioning the same to dentist. Mouth ulcers can be annoying ,frustrating ,advised to get a mouthwash/spray /gel prescribed by dentist for symptomatic relief before eating . Hope that helps!

Hello. Based on your history, the ulcers appear to be chronic (persisting for more than a month) and are associated with burning sensation, bloating, acid reflux, altered bowel habits, and hair fall. Since your Vitamin B12 and ANA reports are within normal limits, the ulcers are less likely to be due to B12 deficiency or an autoimmune disorder alone. Recurrent tongue ulcers can be associated with iron/folate deficiency, gastrointestinal disorders (such as IBS, celiac disease, or inflammatory bowel disease), nutritional deficiencies, stress, hormonal factors, or local irritation. A thorough clinical examination is required before arriving at a diagnosis

Please visit a dentist first to rule out anything related to your oral cavity - sharp teeth, cavities, tartar, leukoplakia, oral lichen planus etc and then we can move ahead further for a diagnosis.
