Hypoglycemia and hyperglycemia are two common metabolic disorders that can interfere with a patient's health. These two conditions, also known as low blood sugar and high blood sugar, are caused by an imbalance in the body's natural ability to regulate glucose. Patients experiencing either of these conditions may experience dizziness, fatigue, blurred vision, and difficulty concentrating. Patients need to be aware of the signs and symptoms of hypoglycemia and hyperglycemia so that appropriate action can be taken to restore a healthy balance of glucose in the body.

What is hypoglycemia or hyperglycemia?

Hypoglycemia is a condition in which the body has low levels of glucose in the blood, usually below 70 mg/dL. Hyperglycemia is a condition in which the body has high levels of glucose in the blood, generally above 180 mg/dL. Both conditions can be dangerous and require medical attention. Symptoms of hypoglycemia include confusion and dizziness, while symptoms of hyperglycemia include increased thirst, increased urination, and fatigue. Treatment for both conditions involves balancing diet and activity levels with medication to maintain healthy blood sugar levels.

What are the causes behind hypoglycemia and hyperglycemia?

Hypoglycemia is caused by a deficiency of glucose in the bloodstream, usually due to not having eaten recently or taken too much insulin or other medications that lower blood sugar levels.

Hyperglycemia is caused by an excess of glucose in the bloodstream, often due to poor diet and lack of exercise, as well as certain medical conditions like diabetes and kidney disease. In some cases, stress can also contribute to both hypoglycemia and hyperglycemia.
