Recognizing Diabetic Emergencies: 5 Signs You Shouldn't Ignore

Diabetes is a chronic condition that requires careful management of blood sugar levels. While many individuals with diabetes successfully control their condition, there are instances when emergencies can arise due to extreme highs or lows in blood sugar. Recognizing the signs of a diabetic emergency is crucial, as prompt action can be lifesaving. In this article, we will explore the five key signs of a diabetic emergency that should never be ignored.

1. Hypoglycemia (Low Blood Sugar)

Hypoglycemia occurs when blood sugar levels drop significantly below normal. It can happen quickly and lead to severe complications if not addressed promptly. Signs of hypoglycemia include:

  1. Shakiness or tremors
  2. Sweating
  3. Rapid heartbeat
  4. Dizziness or lightheadedness
  5. Irritability or confusion
  6. Weakness and fatigue
  7. Nausea or vomiting
  8. Loss of consciousness (in severe cases)

2. Hyperglycemia (High Blood Sugar)

Hyperglycemia is the opposite of hypoglycemia and occurs when blood sugar levels are excessively high. It can result from insufficient insulin or inadequate management of the condition. Signs of hyperglycemia include:

  1. Extreme thirst
  2. Frequent urination
  3. Fatigue or weakness
  4. Blurred vision
  5. Rapid, deep breathing (Kussmaul breathing)
  6. Fruity or acetone breath odor
  7. Confusion or altered mental state
  8. Coma (in severe cases)

3. Diabetic Ketoacidosis (DKA)

Diabetic ketoacidosis is a life-threatening complication of hyperglycemia, typically seen in individuals with type 1 diabetes. It results from a lack of insulin, causing the body to break down fat for energy, leading to the production of toxic ketones. Signs of DKA include:

  1. Excessive thirst and urination
  2. Abdominal pain
  3. Nausea and vomiting
  4. Rapid and deep breathing
  5. Fruity breath odor
  6. Confusion or lethargy
  7. High blood sugar levels
  8. Dehydration

4. Hyperosmolar Hyperglycemic State (HHS)

Hyperosmolar hyperglycemic state is a severe complication seen more often in individuals with type 2 diabetes. It results from extremely high blood sugar levels and severe dehydration. Signs of HHS include:

  1. Profound dehydration
  2. Extreme thirst
  3. Dry mouth and dry skin
  4. Rapid and weak pulse
  5. Confusion or altered consciousness
  6. Seizures (in severe cases)

5. Severe Hypoglycemia Unawareness

Some individuals with diabetes may experience severe hypoglycemia without being aware of the symptoms. This condition is particularly dangerous as it can lead to loss of consciousness and coma without any warning signs. Frequent episodes of unexplained confusion, drowsiness, or loss of consciousness should be taken seriously.


Recognizing the signs of a diabetic emergency is essential for individuals with diabetes and their caregivers. If you or someone you know exhibits any of these signs, seek immediate medical attention. It's also important for those with diabetes to regularly monitor blood sugar levels, follow their treatment plan, and communicate with their healthcare team to prevent emergencies from occurring in the first place. Being vigilant and proactive in managing diabetes is the key to a healthier and safer life with this chronic condition.
