Type 1 Diabetes: Living With the Disease - What Increases Your Risk

Type 1 diabetes puts you at risk for high and low blood sugar and complications.

Risk factors for high and low blood sugar

  • Age. Teen girls are at great risk for high blood sugar, which can lead to diabetic ketoacidosis. Girls are often concerned about their weight and body image, and they may skip insulin injections to lose weight.1
  • Tight blood sugar control. Tight control of blood sugar helps prevent complications, such as eye, kidney, heart, blood vessel, and nerve disease. But it does put you at risk for frequent low blood sugar levels. Tight control means keeping your blood sugar in a target range.
  • Adolescence. The rapid growth spurts and changing hormone levels of adolescence can make it difficult to keep blood sugar levels within your target range. This is the blood sugar goal you set with your doctor.
  • Psychiatric conditions. Eating disorders, depression, anxiety disorder, panic disorder, and addiction to alcohol or drugs increase the risk of frequent high and low blood sugar levels.

Risk factors for complications

It is hard to know why some people develop complications and others do not. Factors that contribute to the risk of complications include:

6 Diet Tips to Help Manage Diabetes Nerve Pain

If you have diabetes, you already know the drill. What you eat, when you eat, and how much you eat can send your blood sugar skyrocketing -- or make it plummet. For better or worse, "diet and diabetes" go together like salt and pepper. So if you need a little motivation to eat better - and who doesn't? - consider this: with diabetes, you're at high risk of the nerve pain and damage called diabetic neuropathy. What can start as a little tingling or numbness in your feet can turn into major problems...

  • Having one complication. If you have one complication from diabetes, you have a greater chance of getting other complications.
  • Ongoing high blood sugar over time. If your blood sugar levels are high most of the time, you have a higher chance of getting complications.
  • Length of time you have the disease. The longer you have diabetes, the more likely you are to develop complications, even if you control your blood sugar levels.
    • Diabetic retinopathy. About 60% of people with type 1 diabetes get diabetic retinopathy after 10 years. Almost all have it to some degree after 20 years. About 25% get the advanced stage (proliferative retinopathy) after 15 years.2
    • Diabetic nephropathy. Diabetic nephropathy eventually occurs in 20% to 30% of all people with type 1 and type 2 diabetes. Without treatment to slow kidney disease, most people with diabetic nephropathy will move from the early stage to the advanced stage of nephropathy in 10 to 15 years.3 Children who get nephropathy usually show the first signs of the condition after puberty.
    • Heart and large blood vessel disease. About 75% of adults with diabetes have high blood pressure. People with diabetes are 2 to 4 times more likely to die from heart disease or to have a stroke.4
    • Diabetic neuropathy. About 60% to 70% of people who have diabetes develop some diabetic neuropathy over time. Many people with diabetes are unaware of any symptoms.4
  • Other risk factors. Other factors that can raise your chance of getting complications include:
    • Smoking.
    • High blood pressure.
    • High cholesterol.
    • Family history of heart disease.
    • Peripheral arterial disease.
    • Psychiatric disorders (such as depression) which can affect how much you want to take care of your diabetes.
    • Family history of diabetic complications.
    • Not having health insurance for supplies and other medical expenses related to diabetes.

Your level is currently

If the level is below 70 and you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.

People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.

Congratulations on taking steps to manage your health.

However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.

Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.

Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.

One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
