hi Dr. Samuel. N. Grief i am 14 years old and in year 9 at high school. lately I have been very tired, dizzy and getting head spins which causes blurry vision. I have also been very very very thirsty and i drink a good 2 litres a day but it dosent seem to be quenching my thirst. During the day i have been having large headaches and my friends are saying ive been having large moodswings. I have also notice that i am hungry all the time and even though i eat im still always hungry 10 minutes after. Im also having skin problems and im also very itchy everywhere. Also I have been feeling very sick and having alot of nausea. I tell my mum all the time of these problems but she waves them off saying that it is my time of the month (this is not period problems). I am curently diagnosed with tourett syndrome and adhd, my great grandmother had diabeties and my mum, aunties and uncles all have under active thyroid problems that they need medication for. Please help Thankyou.
