Can Low Blood Sugar Cause Nausea?

Yes, low blood sugar (hypoglycemia) commonly causes nausea along with other uncomfortable symptoms. When blood glucose drops below 70 mg/dL, your body triggers a stress response that affects the digestive system, leading to nausea, vomiting, and stomach discomfort. This occurs because your brain and organs aren't receiving adequate fuel to function properly. Other symptoms typically accompany the nausea, including dizziness, sweating, shakiness, confusion, and rapid heartbeat. The nausea usually resolves within 15-20 minutes after consuming fast-acting carbohydrates like glucose tablets, fruit juice, or candy. If you experience frequent episodes of low blood sugar with nausea, consult your healthcare provider to identify underlying causes and develop an appropriate management plan.
