Symptoms of diabetes in men in the early stages first require distinguishing by gender. Diabetes can be characterized by "three excesses and one deficiency": excessive drinking, excessive eating, excessive urination, and weight loss, which are typical symptoms. Of course, many patients, such as those in the early stages of type 2 diabetes, may have atypical symptoms such as itchy skin, blurred vision, and foamy urine which appears more foamy. There might also be dental cavities characterized by severe decay, or some men might experience sexual dysfunction. These symptoms may be related to diabetes, and if these symptoms appear, it is important to consider checking blood sugar levels to confirm the presence of diabetes.
