Here are some warning indicators to check for: Increased thirst and more frequent urine: Diabetes may be indicated by increased thirst and more frequent urination than usual. Diabetes can cause dehydration due to frequent urination, resulting in persistent thirst. Unexplained weight loss: Even with an increased appetite, diabetes can cause unexplained weight loss, especially in type 1 diabetes, where the body does not produce enough insulin. Fatigue: Feeling overly fatigued or weak despite adequate rest may indicate diabetes, as the body's cells may not be receiving enough glucose for energy.
