An iron saturation of 5.64% shows that you most likely have iron deficiency anemia. It would be good to consult a doctor and show him/her the full results of your full blood count (haemoglobin levels) and the full iron studies (including ferritin level).
Iron deficiency anemia could be caused by dietary iron deficiency. But more importantly, it could be due to blood loss which could be due to various reasons. In females, one common cause of iron deficiency anemia due to blood loss is menstrual blood loss. Another important source of blood loss is the gastrointestinal tract (eg stomach or large intestine).
I would suggest that you consult a doctor and he/she will be able to help you further.

Dear @GiuliaManfredi  There are different types of COVID-19 vaccination-eg MRNA, inactivated virus etc.  Covid-19 vaccination should not affect your control of Graves's disease and taking Methimazole is not a contraindication to COVID-19 Vaccine in Singapore. (https://www.moh.gov.sg/covid-19/vaccination/faqs---safety-and-efficacy-of-the-covid-19-vaccine)

You might wish to have a personalised discussion with your Endocrinologist about your condition and whether the COVID-19 vaccines available in your country is suitable for you.

Hope this helps.

Dear @Oxmane44 Topical treatment such as can be used for underarm excessive sweating. Botulinum injection eg Botox can also be injected in the underarm to reduce sweating. If the above is unable to help control your excessive underarm sweating, surgery - thoracic sympathectomy might be useful to help reduce sweating over under armpits. Hope this helps.

Hi. I am afraid you have to get a pregnancy test done at some point, the earlier the better. The morning-after pill (Plan B) is known to cause irregular bleeding after taking it; failure of the pill to work is possible, especially if not taken in a timely manner. If your pregnancy test is negative, you can safely do nothing and wait for your proper period to start. If you are indeed pregnancy, then help is easily available to get your though this rough patch. Many clinics in Singapore, including mine, are able to provide the necessary counselling and support for unplanned pregnancies. Your first step is to determine if you are indeed pregnant. So please do get a simple urine test done, either at home, or in the clinic. Everything else will fall into place thereafter.

Cobblestone throat is a description of swelling at the back of the throat due to inflammation.  It will not cause your throat to close.  

Dear Justin,

That would be a little unusual. Typically, stitches are removed after 14 days but the doctor may elect to leave them in for a little longer to aid wound healing if the wounds are slower to heal. However, 36 days could be a little longer than expected. Please consult with your doctor
