16 Sneaky Symptoms That Could Mean Your Blood Sugar Is Too High

7. Unexplained Weight Loss

Rapid, unintentional weight loss is often a red flag for undiagnosed diabetes, particularly type 1 diabetes. When the body cannot use glucose due to insufficient insulin production, it starts breaking down fat and muscle for energy, leading to significant weight loss even when appetite remains normal or increases. This process, known as catabolism, can be physically draining and lead to additional symptoms like muscle weakness and fatigue. Unexplained weight loss is a stark indication that the body is struggling to maintain its energy balance. In type 2 diabetes, significant weight loss may also occur during periods of hyperglycemia, as excessive glucose is excreted in urine. Individuals experiencing sudden weight changes should seek immediate medical evaluation, as this symptom could signal not only diabetes but other serious metabolic or endocrine conditions.

8. Tingling or Numbness in Extremities (Neuropathy)

Diabetic neuropathy is a common complication of prolonged high blood sugar levels and often begins with a tingling or numb sensation in the hands and feet. These symptoms, sometimes described as "pins and needles," are the result of nerve damage caused by insufficient blood flow and chronic inflammation. As the condition progresses, individuals may experience burning sensations, sharp pains, or complete loss of feeling in the affected areas. Neuropathy can make simple tasks like walking or holding objects challenging and increase the risk of injuries, as patients may not feel cuts or burns. Left unmanaged, it can impair mobility and lead to infections or ulcers. Early detection and blood sugar control are critical to slowing nerve damage and maintaining function.
