Ginger can help digestion by stimulating bile production, but this isn’t always a good thing. For people with gallstones or gallbladder problems, increased bile flow can trigger pain and discomfort, as the gallbladder may struggle to release bile properly. In these cases, ginger may worsen symptoms rather than help.
3. People with diabetes
Ginger may help lower blood sugar, which can be beneficial for some people with diabetes. However, for those taking blood-sugar-lowering medications, it can increase the risk of levels dropping too low, potentially leading to hypoglycemia. It would be for the best to consult a doctor before consuming ginger on a regular basis while on medications that regulate blood-sugar levels, especially if taking additional medications including anticoagulant drugs, such as warfarin; antiplatelet drugs; and blood pressure medications.
Rahaf Al Bochi, RD, a spokesperson for the Academy of Nutrition and Dietetics stated, “We know that ginger can affect your insulin levels. If you’re taking ginger supplements and you are on diabetes medication, that can cause low blood sugar, or hypoglycemia.”
