What Are Some Symptoms of Hyperglycemia and Hypoglycemia?

Symptoms of hyperglycemia include frequent urination, weight loss, increased thirst and increased sugar levels in the urine, states Healthline. Symptoms of hypoglycemia include loss of consciousness, rapid heartbeat, sudden changes in mood and sweating.

Noticeable symptoms of hyperglycemia, or high blood glucose, are rare, and can develop over several days. This condition occurs from an incorrect dosage of glucose-lowering medication, illness and poor food choices. If hyperglycemia remains untreated, it can result in heart or kidney disease, nerve damage, and diabetic ketoacidosis, reports Healthline. Diabetic ketoacidosis occurs due to insufficient insulin in the body, preventing sugar from entering the body, which causes increased sugar levels and breakdown of fat for energy, explains Mayo Clinic.

Hypoglycemia occurs when the body produces insufficient sugar, and symptoms vary among people. If hypoglycemia remains untreated, it can result in severe symptoms, such as passing out, poor concentration and coordination, and numbness in the mouth, reports WebMD. This condition can occur from skipping meals, exercising more than usual and taking medications that increase insulin production, such as nateglinide, glimepiride and repaglinide, according to Healthline.

Patients should write down the date and time when hypoglycemia symptoms begin and share the same with their doctor, allowing the doctor to adjust any medications, says WebMD. Some doctors recommend pregnant women and those planning to become pregnant to get treatment for this condition, advises Mayo Clinic.
