20 Signs of High Blood Sugar

17. High fever:

High fever may indicate high blood sugar levels due to weakened immune system functioning. The immune system is responsible for defending the body against infections and illnesses. A healthy immune system protects against sickness, but individuals with high blood sugar experience compromised immune systems. High blood sugar and diabetes are autoimmune disorders where the body attacks itself. Elevated blood sugar levels are not caused by an external germ but rather a malfunction in the body's ability to metabolize sugars.

The immune system becomes preoccupied with combating the high sugar levels in the blood, making it susceptible to opportunistic infections. Bacteria and viruses can infiltrate and cause infections, resulting in high fevers. Fever and dehydration create a detrimental cycle as fever leads to dehydration, and dehydration worsens the fever. High blood sugar can induce excessive thirst, but the fluids consumed are eliminated as urine due to the condition, resulting in real risks of dehydration. Infections often occur in areas such as the urinary tract, vagina, gums, feet, and skin for individuals with high blood sugar and diabetes.

A fever of 101ºF or higher is indicative of a severe problem. If you have a family history of high blood sugar levels, it is advisable to undergo testing. When treating an extreme fever, doctors should routinely check the patient's blood sugar levels.
