Brittle diabetes is the name doctors give diabetes that is especially hard to control. It’s also called “labile” diabetes. The words brittle and labile can both mean “unstable” or “easily changed.”
It's almost always associated with type 1 diabetes. It isn’t a separate kind of diabetes, but more like a complication, or subset of the disease.
Causes and Symptoms
Because any diabetes can be unstable when you don’t manage it well, a brittle diabetes diagnosis can be tricky. If your blood sugar levels swing wildly, there could be many reasons for it, including:
- You’re not taking your medication or testing your glucose levels like you should.
- Lots of stress
- An eating disorder
- Your intestines struggle to absorb nutrients.
- Celiac disease
- Gastroparesis -- a condition that slows down or stops the emptying of food from your stomach into your intestines
- You're very sensitive to insulin
Often, it can be one or more of these. In many cases, doctors don’t know exactly what causes it.
Depending on which way your blood glucose level in swinging, your symptoms can be different. They're "very low" at below 70 mg/dl. Symptoms can include:
- Feeling shaky
- Nervousness or anxiety
- Sweating, chills
- Fast heart rate
- Blurred vision
When your blood sugar shoots up above 200 mg/dl, your symptoms will likely include:
It can cause:
Who Gets It?
Brittle diabetes isn't common. About 3 out of every 1,000 people who take insulin for diabetes will get it.
People of all ages can have brittle diabetes. Women get it a bit more often than men. If you often have bouts of low blood sugar, you may be raising your odds, as well. The more often you’re hypoglycemic, the less you may recognize it. That can make each episode worse and lead to brittle diabetes.
Living With It
It's a disruption to your daily life. You can’t predict when you’ll be dealing with a low or high swing in your blood glucose. Hospital stays are common. It can make it hard to work and keep up with your day-to-day tasks.
It can also be fatal.
To treat you, your doctor will work on any immediate blood sugar needs you have first. You’ll need to closely manage your diabetes. New technology and treatment options for insulin control may make it easier to regain some control.
You may get:
A continuous glucose monitor: This tool measures the glucose levels in your blood at regular intervals using sensors placed under or over the skin. Signals are sent to a monitor that can be clipped to a belt. If your blood sugar levels drop too low or rise too high, the monitor will sound an alarm.
An insulin pump: A small machine that stays connected to you throughout the day to give you steady adjustments in insulin.
The treatment your doctor will choose depends on what’s causing your brittle diabetes. Once you have a plan, be sure to give yourself the best shot for success:
- Follow your nutrition guidelines.
- Stick to your medication schedule.
- Most of all, stay in touch with your diabetes team so you have both the medical and emotional support you need.
