  ≥ 3.5 g/dl at baseline.

• Patients with gastric cancer with a negative CT or MRI scan (total abdomen).
• Karnofsky Performance Status ≥ 60 (i.e. required occasional assistance, but was able to care for most of their personal needs)
• Patients who received other therapies for dumping syndrome (such as acarbose, gama guar, pectin) must have stopped all treatments and had a wash out period prior to signing the informed consent (i.e. at least 2 weeks between last previous therapy and first dose of study medication in this study).
• Patients who had provided signed written informed consent prior to study participation.

Exclusion Criteria:
