Experiencing symptoms like sweating, shaking hands, irritability, and general discomfort after not eating for about 14 hours can raise concerns about blood sugar levels. However, these feelings are often a normal response to hunger rather than a definitive indication of a blood sugar problem. It is suggested to undergo a glucose test for a clearer understanding of one's blood sugar status. While fasting for 14 hours is considered long, some individuals can manage it without severe issues, though regular eating is recommended for overall well-being. Hydration is also crucial, as dehydration can exacerbate feelings of discomfort more than hunger. It's noted that a well-nourished person can survive significantly longer without food than without water, highlighting the importance of both nutrition and hydration.
