According to your post you have had nausea and sometimes vomiting for a long time and now headaches occurred as well. Prolonged nausea and vomiting is typical for presence of a metabolic disorder, a chronic disease, or it may have a psychogenic cause. Nausea and vomiting in the morning indicates that you might have a gastrointestinal or metabolic disorder (uremia, diabetes…). It could also be related to the abdominal surgeries that you had in the past.
You need several diagnostic procedures to find out the cause:
1. Physical examination (inspection and palpation of the abdomen and neurological examination);
2. Laboratory tests (blood count, hemoglobin, sedimentation, glucose, CRP, AST, ALT, alkal phosphatase, bilirubin, creatinin, urea, amylases…);
3. Abdominal ultrasound and gastroscopy (later).
You may want to consult an internist about your problem.
