However, ginger and ginger water may be helpful for the following conditions:
People have long used ginger as a herbal treatment for nausea. In a 2015 review, researchers looked at nine studies in which people used ginger for postoperative nausea, chemotherapy side effects, viral nausea, and morning sickness. The studies, although not always clinically watertight, all indicated that ginger provided a reduction in nausea and vomiting.
In another study, researchers divided 10 men into two groups. One group drank hot ginger water after eating breakfast. The other group did not. The men who drank the ginger water reported greater feelings of fullness.
Although the study was small, and additional studies are necessary, it suggests that ginger water might have a role in weight management.
