Warning Signs of Hyperglycemia and Hypoglycemia

Diabetes is a chronic condition of the body caused by increased blood glucose levels in the blood. Elevated blood sugar levels are regarded as hyperglycemia (more than 140 mg/dl).

A specialist at Humble, TX critical care medicine treats diabetic patients with the help of lifestyle changes and keeps blood sugar levels in control.


This is a condition in which the blood glucose level is more than 200 ml/dl post-meal. This condition occurs in patients having difficulties with insulin sensitivity.


  • Thirst 

Patients suffering from hyperglycemia feel thirsty, have a dry mouth, consume a lot of water, and urinate frequently.

  • Weight Loss

During hyperglycemic conditions, the glucose will not reach the body tissue, which signals to the brain that the body is in a starving condition. As a result, the body starts burning fat to create energy to maintain normal metabolic processes occurring in the body.

  • Vision 

People observe blurred vision due to alteration in the lens or by the changes occurring in the retina.

  • Breath 

If the hyperglycemic condition is not treated, the body undergoes the state of forming ketone bodies, which causes ketoacidosis. As a result, there will be the presence of fruity smell in breath.

  • Muscle weakness 

A person having type 2 diabetes will have impairment in the ability of the muscle to consume glucose. As a result, the muscle becomes weak, and atrophy(decrease in cell size) may occur.


This is a condition in which the blood glucose level will be less than 70mg/dl. This condition occurs in person as a side effect of taking blood glucose-lowering medication.


  • Excess sweating 

People who intake medication such as insulin or sulfonylureas will sweat more often at night as the body produces adrenaline in high amounts, which causes excessive sweating.

  • Appetite

A person suffering from low blood glucose will have increased appetite as the body will release stored glucose from the liver to maintain the average glucose level.

  • Tachycardia 

An increase in the release of catecholamines during hypoglycemia will cause arrhythmia, high heartbeat.

  • Mood swings 

People suffering from low blood glucose levels will always have confusion, aggressiveness, and irritability. People are unable to concentrate.

  • Trembling 

Patients suffering from hyperglycemia will result in the release of epinephrine and norepinephrine to signal the brain to normalize the blood glucose level, which often causes tremors.

If you observe any of the signs mentioned above, you must consult a doctor to get a proper diagnosis and treatment.
