Less familiar warning signs can sometimes appear on the skin. Darkened patches of skin, especially around the neck, underarms, or groin, may indicate insulin resistance. This condition is often associated with type 2 diabetes and can develop years before diagnosis.

Some people experience recurrent sinus problems, gum issues, or skin infections. Others may notice tingling, numbness, or unusual sensations in their hands and feet. These symptoms can occur when high blood sugar begins affecting nerves.
Unexpected weight loss can also be a warning sign, particularly in cases where the body is unable to use glucose effectively and starts breaking down fat and muscle for energy. While weight loss is often viewed positively, unexplained changes should always be discussed with a healthcare professional.
