I am 20 years old and have some strange symptoms which when I read in Internet can be symptoms of cancer and I don't know what to do.
I have lost about 15kg in the last 6-7 months. I have gained about 7-8kg in the last two years or so but it is strange how I know lost so much weight in such a short time when I eat the same amount of food. Can it be from the more dynamic way of life when I am in university know?
Also, what I am more worried about, from the beginning of the year about 4-5 times I have strange nausea, I vomit couple of times and feel really dizzy without any visible reason and this continues for hours (maybe 8-9 hours) and then I am ok.
Please, can someone tell me if I should be worried and consult a doctor?
