Sir, my tongue is very strange, my tongue is very red and shiny, and what's the cause?
gpt
There may be a lack of vitamin B12, which causes the tongue to feel red, shiny, sick or burned.
Doctor, I'm experiencing weight gain and facial blushing. What's the problem?
It seems to be hypothyroidism, which means that the thyroid doesn't produce enough hormones to regulate metabolism and body temperature.
