What is brittle diabetes?

The simple answer is that it is a rare form of type 1 diabetes in which it is extremely hard to manage blood sugars.

I mean beyond the usual fluctuations that occur in diabetes.

Some people just can’t seem to get a grip on those blood sugar numbers.

They are high (hyperglycemic), then low (hypoglycemic) regardless of all attempts at effective management.

Brittle diabetes, a rare condition that affects mainly those with type 1 diabetes, particularly women in their 20’s and 30’s.

Brittle diabetes can also be referred to as labile diabetes.

The words brittle and labile can both mean “unstable” or “easily changed”.

It is quite rare affecting only 1 in a thousand insulin-dependent diabetics.

We have found that while our grandson’s blood sugar levels do fluctuate, they don’t do so wildly.

We are able to keep a tight grip on his numbers though and treat any highs or lows before they become serious or risk complications.

What is Brittle Diabetes

Brittle diabetes is actually a rare form of insulin-dependent diabetes signified by frequent and severe episodes of hypoglycemia and/or hyperglycemia.

This instability of blood sugar levels often leads to hospitalization.

Frequent self-monitoring of blood glucose is essential.

Using a continuous glucose monitor (CGM) and an insulin pump can make brittle diabetes easier to manage especially with a closed-loop system.

Although rare, sometimes a pancreas transplant may be necessary.

Causes and symptoms

Any diabetes can be unstable when you don’t manage it well.

However, if your blood sugar levels are swinging wildly there could be many reasons for it, such as:

  • You are not taking medication or testing blood sugars as you should be
  • a high amount of stress
  • hormonal imbalance
  • an eating disorder
  • your intestines are not effectively absorbing nutrients
  • celiac disease
  • hypothyroidism
  • gastroparesis
  • you are extremely sensitive to insulin
  • drug or alcohol use

Quite often, doctors don’t know exactly what causes brittle diabetes but it can be one or more of these.

Symptoms of Hypoglycemia

Any diabetic or caregiver will recognize these symptoms of hypoglycemia (low blood sugars):What is Brittle Diabetes? - sweating

There are three levels of hypoglycemia.

  • Level 1 (mild)
    • blood glucose is less than 70 mg/dL  but more than 54 mg/dL
    • may experience sweating, shaking, nausea, extreme hunger, nervousness, dizziness
  • Level 2 (moderate)
    • blood glucose is less than 54 mg/dL
    • may experience some of the above as well as difficulty concentrating or speaking, confusion, weakness, vision changes, mood swings
  • Level 3 (severe)
    • the person is unable to function because of mental or physical changes
    • this is where the person is unable to take fast-acting sugar themselves and requires assistance, they may be unconscious or have seizures. They need to be treated with a Glucagon Emergency Kit.

It is important to realize that some people may experience some or all of these symptoms and some only a few.

Hypoglycemia Unaware

We have discovered that Alex, is actually Hypoglycemic Unaware, not really a good thing.

We believe this could be because of his young age and he is unaccustomed to really have to notice how his body feels.

Our daughter is really trying to teach him to describe how he feels when his blood sugars are low or high.

As his caregivers, we notice he is sometimes sensitive or cranky when his blood sugars are low.

When his blood sugars are high the only way we know is by testing him.

Because Alex doesn’t seem to know whether he feels high or low, it is important for us to test his blood sugar levels frequently.

Thankfully he wears a continuous glucose monitor(CGM) which really cuts down on the number of finger pokes.

I would certainly recommend having a discussion with your doctor to determine if a CGM would be a beneficial part of your diabetes management plan.

For us, a CGM has been a game-changer.

Symptoms of HyperglycemiaWhat is Brittle Diabetes? - excessive thirst

A Diabetic person may have some of these early symptoms of Hyperglycemia (high blood sugars):

  • excessive thirst
  • frequent urination
  • headaches
  • trouble concentrating
  • blurred vision
  • weak, tired feeling
  • unplanned weight loss
  • tests high with a blood glucose monitor

If left untreated the person may also experience:

  • vaginal and skin infections
  • worse vision
  • cuts and sores may be slow to heal
  • nerve damage causing painful or cold feet, hair loss on the lower extremities, or erectile dysfunction
  • chronic constipation or diarrhea
  • damage to eyes or kidneys

Alex’s CGM is truly helpful in knowing when Alex’s blood sugars are too high.

By simply scanning him we know which direction his numbers are trending and can treat him before anything serious develops.

Diagnosis

It is because any diabetes can be unstable at times due to improper management that makes diagnoses of brittle diabetes difficult.

However, those who truly have brittle diabetes experience wildly fluctuating blood sugar levels in spite of their best efforts to control them.What is brittle diabetes?

People with brittle diabetes are frequently hospitalized with severe hypoglycemia or hyperglycemia and often diabetic ketoacidosis (DKA).

Brittle diabetes is often accompanied by psychological problems such as stress and depression. This can lead to neglecting self-care causing wild blood sugar swings.

For example, people with brittle diabetes may stop eating their healthy diet or managing their blood sugars altogether.

As blood sugar control ceases, the resulting metabolic imbalances may further complicate or worsen any underlying psychological problems.

This causes a repetitive vicious cycle.

TreatmentWhat is Brittle Diabetes? - insulin pump

Because the main problem with brittle diabetes is the unpredictable fluctuations in blood sugar levels, switching to a reduced carbohydrate diet may help reduce those rapid blood sugar swings.

Consuming fewer carbohydrates may lessen the frequency of sharp rises and drops and/or make them less severe.

Increasing the frequency of monitoring blood sugar levels and making any necessary corrections before they become severe will also help in better blood sugar management.

It would also be a great idea to take advantage of today’s technology and use a continuous glucose monitor (CGM) or an insulin pump.

A closed-loop system such as T-Slim Control IQ system that pairs with a Dexcom G6 device would be ideal.

While technology may not be right for everybody it may be worth discussing with your diabetes care team to see if it could help you gain better control over your blood glucose levels.

Our young grandson does wear an insulin pump.

Although I believe they will soon be discussing it with his diabetes care team because he is starting to ask about wearing one.

He understands that a pump will mean he won’t need four needles a day because the pump will deliver his insulin.

Be sure to discuss with your doctor whether a pump is right for you.

Final Thoughts

Until recently, I had never heard of, let alone understand what is brittle diabetes.

We have learned that brittle diabetes is simply uncontrolled blood sugar levels that fluctuate wildly and often require hospitalization.

Brittle diabetes is extremely rare.

If diagnosed it is important to follow a healthy, low-carb diet and take all medications as directed by your diabetes care team.

Increasing the frequency of testing blood sugar levels is important.

Technology such as continuous glucose monitors (CGM’s) and/or insulin pumps can really help keep a tight rein on those blood sugars.

    • Thanks for stopping by Aparna and taking the time to comment.
      I am sorry to hear your granny is having trouble managing her diabetes.
      I am grateful I could help you see the necessity of getting her medical help.
      Hopefully, the doctors can find a way to get her blood sugars more manageable.
      Perhaps a continuous glucose monitor or an insulin pump may help.
      I wish you both all the best. Take care.

  2. Wow. Another diabetes I haven’t heard of. It is so cruel one apparently. The Father of my girlfriend has as well one, so I know how harsh this disease can be, (even it did not appear in the first place) He is now really dependant on insulin and tired a huge part of the day…Would you suggest for him as well the carbohydrate diet? Great article.

    • Thanks for commenting, Julius. I am sorry to hear your girlfriend’s father is struggling to manage his diabetes. Effective diabetes management is time-consuming, to say the least. I would recommend he works with his diabetes management team which should include a dietician to determine the best diet for him. With our grandson, we don’t limit his carbs but we do have to compensate for them by giving him insulin at mealtimes. Calculating those carbs is an important part of every meal. I wish you all the best and hope he is able to get those blood sugars under control.
