Dr. James Sebastian, MD, FAGM, one of the best diabetes doctors in Kochi.Diabetes affects much more than blood sugar. A deviation in level of blood sugar can lead to sudden mood swings that can put emotional strain on relationships and personal life. For some people, there will be a stress of living with diabetes that can contribute to mood swings as well as concerns about possible complications. The physical effects lead to nervousness, anxiety, and confusion. Our friends, family and other closed ones can have trouble understanding these mood swings, but learning how diabetes affects mood and if we provide enough support, can help nurture stronger, healthier relationships.
