Tenho tido dor abdominal superior há duas semanas, alguma sugestão?

Hi friends, I am a 25 year old male. Since two weeks ago I have been having occasional upper abdominal pain - the pain is not consistent and of the level of 2-3 on the scale from 0 to 10. The pain is mainly located in the stomach region (underneath the xiphoid) but can also go sideways to my left side. It is more often a sharp pain than a dull pain. Sometimes pain in the umbilical region is also experienced. I have been losing weight (>5 kg for the past month, if not shorter) and having bad breath (hard to describe the smell but it is not the acetone smell). At the beginning the color of my stool was yellow but now it is brown again. I am not having jaundice but it seems that I get bruised more easily than before. My blood test and ultrasound didn't show anything abnormal, but I am quite worried. Could anyone give me some advice and tell me if you experienced similar symptoms before? Thank you very much in advance.

It could be GERD and dyspepsia that’s troubling you.

Try antacids. Elevate your head while sleeping ( use 2 pillows ). Eat small portions of food 5-6 times a day instead of 2-3 large meals.
