Which early signs are typical of hyperglycemia in a patient with diabetes?

• A. Polyuria, polydipsia, and dehydration.
• B. Rapid weight gain.
• C. Cold, clammy skin with sweating.
• D. Severe hypertension.

Answer: (A)

When blood glucose is high, the kidneys try to remove the excess sugar by urinating it out. Water follows the sugar into the urine, leading to more urination. That fluid loss triggers thirst and can leave the patient dehydrated. These three clues—increased urination, increased thirst, and dehydration—are classic early signs of hyperglycemia in someone with diabetes. Other options don’t fit the early picture: rapid weight gain isn’t typical; high blood sugar more commonly leads to weight loss as the body can’t effectively use glucose and begins breaking down fat and muscle for energy. Cold, clammy skin with sweating points to low blood sugar (hypoglycemia) rather than high. Severe hypertension isn’t an early hallmark of rising glucose levels. In an EMS context, spotting polyuria and polydipsia with dehydration helps point toward hyperglycemia rather than the other conditions.
