Hello, my nausea is becoming worst. ive lost weight recently. i weigh 40kgs im 165cm, female, 17 years old. ive been feeling nauseous and vomiting after most of my meals even when i do feel hungry, i also feel weaker and i have troubles breathing.

See below: Sorry that you are ill- I would suggest that you see your doc as soon as possible - weakness and shortness of breath are not normal - It may be something simple - like anemia from poor iron intake, but given the limit information I cannot tell you what is wrong- but these are not normal in a young person -you need an evalution from your doctor ASAP - Good luck

Nausea & weight loss: I agree with Dr. Bosshardt , We can't diagnose your symtoms. Please let your parents know that you have been ill, so that they can arrange for an evaluation by your physician. Take care.
