Brittle diabetes, also known as labile diabetes, is a rare and severe form of diabetes mellitus characterized by extreme fluctuations in blood sugar levels. People with brittle diabetes experience frequent and unpredictable swings between high blood sugar (hyperglycemia) and low blood sugar (hypoglycemia), often without apparent cause.

Definition of Brittle diabetes.

Brittle diabetes is a term used to describe an uncommon and severe form of diabetes mellitus characterized by extreme and unpredictable fluctuations in blood sugar levels. Unlike the stable blood sugar control typically seen in most individuals with diabetes, those with brittle diabetes experience rapid and severe swings between high blood sugar (hyperglycemia) and low blood sugar (hypoglycemia), often without an obvious trigger or apparent cause.

Causes and Risk Factors:

Here are some common causes and risk factors.

Insulin Sensitivity and Production Issues: Problems with insulin sensitivity or insufficient insulin production by the pancreas can contribute to unstable blood sugar levels. In some cases, individuals with brittle diabetes may have a severe form of insulin resistance, making it difficult for insulin to regulate their blood sugar effectively.
Hormonal Imbalances: Hormonal fluctuations, such as those associated with conditions like polycystic ovary syndrome (PCOS) or thyroid disorders, can impact blood sugar control and contribute to the brittleness of diabetes.
Medication Interactions: Some medications, including certain drugs used to treat other medical conditions, can interfere with the action of insulin or other diabetes medications, leading to blood sugar instability.
Stress: High levels of stress, whether from daily life stressors, emotional factors, or illness, can significantly affect blood sugar levels. Stress hormones like cortisol can cause blood sugar to rise.
Inadequate Diabetes Management: Poor adherence to medication regimens, irregular meal patterns, and inconsistent monitoring of blood sugar levels can all contribute to blood sugar fluctuations.
Dietary Factors: Inconsistent or erratic eating habits, as well as consumption of foods that cause rapid spikes or drops in blood sugar (e.g., sugary snacks or high-carbohydrate meals), can lead to instability in blood sugar levels.
Alcohol and Substance Use: The consumption of alcohol or certain drugs can disrupt blood sugar regulation and contribute to hypoglycemia or hyperglycemia.
Underlying Medical Conditions: Coexisting medical conditions, such as gastroparesis (delayed stomach emptying), can affect digestion and nutrient absorption, making it challenging to manage blood sugar levels.
Psychological Factors: Emotional factors, including anxiety, depression, and other mental health issues, can impact diabetes management. Stress and emotional distress can lead to erratic blood sugar patterns.
Individual Variability: Some individuals may simply be more prone to extreme blood sugar fluctuations due to genetic or physiological factors.
Infections or Illness: Illnesses and infections can stress the body and affect blood sugar levels, making it harder to maintain stable control.

Symptoms and Diagnosis:

Here are some common symptoms and information on the diagnosis of brittle diabetes.

Symptoms of Hyperglycemia (High Blood Sugar):

Excessive Thirst: Feeling constantly thirsty and drinking large amounts of fluids.
Frequent Urination: Urinating more frequently than usual.
Fatigue: Persistent tiredness and lack of energy.
Blurred Vision: Vision may become blurry or hazy.
Increased Hunger: Constant feelings of hunger, even after eating.
Dry Skin and Mouth: Skin may become dry, and the mouth may feel parched.
Frequent Infections: High blood sugar levels can weaken the immune system, leading to an increased risk of infections.

Symptoms of Hypoglycemia (Low Blood Sugar):

Sweating: Profuse sweating, especially when not exerting physically.
Trembling or Shaking: Uncontrollable trembling or shivering.
Rapid Heartbeat: Heart palpitations and a fast heartbeat.
Dizziness: Feeling lightheaded or dizzy.
Irritability: Sudden mood changes, including irritability or nervousness.
Confusion: Difficulty concentrating or thinking clearly.
Hunger: Intense hunger and cravings for sugary foods.
Weakness: Muscle weakness or a feeling of extreme fatigue.
Headache: A persistent headache.

Diagnosis of Brittle Diabetes:

Medical History: The process of diagnosing brittle diabetes typically begins with a detailed medical history. A healthcare provider will ask about symptoms, blood sugar patterns, medication regimens, diet, lifestyle, and any underlying medical conditions.
Blood Sugar Monitoring: Continuous or frequent monitoring of blood sugar levels is essential. This may involve using a blood glucose meter to track daily fluctuations. Patterns of extreme highs and lows over time may raise suspicion of brittle diabetes.
Hemoglobin A1c Test: This blood test provides an average of blood sugar levels over the past two to three months. Individuals with brittle diabetes may still have a high A1c, indicating poor long-term blood sugar control, despite experiencing frequent fluctuations.
C-peptide Test: This test measures the level of C-peptide in the blood, which can help determine the body’s ability to produce insulin. Low levels of C-peptide may suggest reduced insulin production.
Other Tests: Additional tests may be ordered to investigate underlying factors contributing to brittle diabetes, such as hormonal imbalances or coexisting medical conditions.
Psychological Assessment: Because stress and psychological factors can significantly impact blood sugar control, a psychological assessment may be conducted to evaluate the emotional well-being of the individual.
