Recurrent Aphthous Stomatitis (6 mins)
27-year-old patient presents with ulcers. The patient’s ulcers are no more than 10mm in size (history provided, etc.).

You do not need to gain any more information from the patient. Minor apthous ulcers
Explain to the patient their diagnosis.
- You have microcytic aneamia as a result of low iron and folate.
- This means that you have less RBC’s in your body

- As a result of less oxygen you may feel tired, breathless or paler
- In addition to this you can also present with small ulcers in the mouth which last about 2 weeks and heal with no scaring.
- Recurrent aphthous stomatitis can also result from a nutritional deficiency, particularly lack of iron, vitamin B3 (as in pellagra), vitamin C (as in scurvy), folic acid, or vitamin B12.
Other causes can be mouth injury, stress, and some foods may trigger an attack.

1. ‘My advice in the meantime is to try and increase the iron in your diet, avoid spicy foods like curries and if your mouth is very sore (can’t eat, etc.), I can prescribe a numbing mouthwash to allow you to be more comfortable
1. - Benzydamine mouthwash 0.15%- send 300ml, label- rinse or gargle using 15ml every 1.5 hours as required (can be diluted 1:1 with water if stinging, spit out after rinsing, not more than 7 days) or CHX (but probably too sore)
