Diabetes

Diabetes is a disease that happens when your body cannot use insulin the right way. Insulin helps move sugar from your blood into your cells for energy. If your body does not make enough insulin or cannot use it well, too much sugar stays in your blood. This can cause health problems over time. People with diabetes face a higher risk of heart disease, stroke, chronic kidney disease (CKD), blindness (retinopathy), nerve damage (neuropathy), and foot problems. People with diabetes can take steps to stay healthy and lower the chance of serious problems. If you or someone in your family has diabetes or was just diagnosed, Fidelis Care can help.



Identifying the Types of Diabetes

There are different types of diabetes, each with different causes, but they all share the common problem of having too much sugar (glucose) in your bloodstream. Select a class in the dropdown to learn more.

Type 1 Diabetes

Type 1 Diabetes occurs when the pancreas does not make enough insulin. People with Type 1 diabetes are usually diagnosed as children or adolescents, and depend on insulin therapy and other treatments to make up for the lack of insulin.

Type 2 Diabetes
Type 2 Diabetes occurs when the pancreas makes some insulin, but it’s not enough to meet the body’s needs. People with Type 2 diabetes are usually diagnosed as adults and are not dependent on insulin therapy.
Gestational Diabetes
Gestational Diabetes can occur in pregnant women. While it doesn’t mean a woman had diabetes before pregnancy or will have diabetes after birth, her doctor’s advice should be followed to remain healthy.
Prediabetes

Prediabetes means you have a higher than normal blood sugar level.  Unmanaged prediabetes can lead to Type 2 diabetes. Prediabetes doesn’t always have symptoms, so it’s crucial to get blood sugar levels tested, especially if you’re at high risk. Losing weight, exercising regularly and healthy eating habits can reverse prediabetes and prevent Type 2 diabetes.

Other Types of Diabetes

According to the American Diabetes Association (ADA), about 2% of people have rarer types of diabetes. Including MODY, LADA, cystic fibrosis-related diabetes, and diabetes caused by rare syndromes.

  • MODY ➤ MODY (Maturity Onset Diabetes of the Young) is caused by a mutation in a single gene. If a parent has this gene mutation, any child they have, has a 50% chance of inheriting it from them. If a child does inherit the mutation, the symptoms of MODY are often established before the age of 25, regardless of their weight or lifestyle.  It’s estimated that 90% of those diagnosed with MODY are mistakenly diagnosed with type 1 or type 2 diabetes at first.

  • LADA  ➤ LADA (Latent Autoimmune Diabetes in Adults) is a type of diabetes which straddles type 1 and type 2 diabetes. The symptoms reported of this variant correspond with each Type 1 and Type 2 diabetes, which is why some people call it type 1.5 diabetes or type 1 ½ diabetes. Whereas being overweight is a major risk factor for type 2 diabetes, people with LADA tend to have a healthy weight.

  • CFRD ➤ CFRD (Cystic Fibrosis-related Diabetes) is a type of diabetes that is unique to children and adults with cystic fibrosis (CF). The accumulation of sticky mucus caused by CF can sometimes lead to inflammation and scarring of the pancreas. This can damage the cells that produce insulin, leading to high blood glucose (sugar) levels. When the pancreas can’t produce enough insulin, blood sugar levels may continue to rise and develop into CFRD.



Managing Diabetes

Controlling your diabetes starts with understanding your body. Regular doctor visits and testing are important ways to stay healthy, make informed decisions, and prevent serious complications.

Recommended tests for diabetes management include:

A1C Blood Sugar - At least twice per year

This blood test measures the average amount of blood sugar in a 2-3-month period. A result below 7 percent helps lower your risk of eye, nerve, and kidney damage. 

LDL Cholesterol - At least once per year

This blood test measures “bad” cholesterol (low-density lipoprotein cholesterol) levels in the blood. A result below 100 mg/dL helps lower your risk of heart disease and stroke.  

Kidney Damage - At least once per year

This urine test measures how well kidneys work. The test works by measuring protein in urine, a sign of kidney damage, which can happen if diabetes is not managed. Kidney damage can result in kidney failure and the need for dialysis. 

Eye Exam - At least once per year

A retinal or dilated eye exam by an eye care professional is recommended for people who have diabetes. The eye exam checks the nerves and small blood vessels of your eyes for damage caused by diabetes. This test should be done once a year even if your eyesight seems normal. If left undetected, this damage can lead to blindness.

Monitoring Blood Glucose

Regular testing helps track your blood sugar levels and identify patterns, making it easier to adjust meals, medication, and activity. For guidance on blood sugar targets for diabetes types and time of day, view our "Recommended Blood Sugar Targets," below. Talk to your provider and diabetes educator about the best goals for you.

Recommended Blood Sugar Targets

For people with type 1 diabetes, the American Diabetes Association recommends that blood sugar targets be based on a person's needs and goals, including whether they are pregnant. Talk to your provider and diabetes educator about the best goals for you. 

General guidelines are:

Before meals, your blood sugar should be:

  • From 90 to 130 mg/dL (5.0 to 7.2 mmol/L) for adults
  • From 90 to 130 mg/dL (5.0 to 7.2 mmol/L) for children, 13 to 19 years old
  • From 90 to 180 mg/dL (5.0 to 10.0 mmol/L) for children, 6 to 12 years old
  • From 100 to 180 mg/dL (5.5 to 10.0 mmol/L) for children under 6 years old

After meals (1 to 2 hours after eating), your blood sugar should be:

  • Less than 180 mg/dL (10 mmol/L) for adults

At bedtime, your blood sugar should be:

  • From 90 to 150 mg/dL (5.0 to 8.3 mmol/L) for adults
  • From 90 to 150 mg/dL (5.0 to 8.3 mmol/L) for children, 13 to 19 years old
  • From 100 to 180 mg/dL (5.5 to 10.0 mmol/L) for children, 6 to 12 years old
  • From 110 to 200 mg/dL (6.1 to 11.1 mmol/L) for children under 6 years old

For people with type 2 diabetes, the American Diabetes Association also recommends that blood sugar targets be individualized. Talk to your provider and diabetes educator about the best goals for you. 

General guidelines are:

Before meals, your blood sugar should be:

  • From 80 to 130 mg/dL (4.4 to 7.2 mmol/L) for adults

After meals (1 to 2 hours after eating), your blood sugar should be:

  • Less than 180 mg/dL (10.0 mmol/L) for adults

Obesity and Diabetes

Being overweight or having obesity can make it more difficult to manage your diabetes and may compound into additional health problems, including heart disease and high blood pressure. If you are overweight and have diabetes, adopting a healthy eating plan with fewer calories and more physical activity often will lower your blood glucose levels and reduce your need for medicines.

How Obesity Affects Diabetes

Obesity-and-Diabetes

Diabetes & Heart Disease

According to the National Institute of and Digestive and Kidney Diseases (NIDDK), individuals with diabetes are more likely to develop heart disease. People with diabetes are also more likely to have certain risk factors, such as high blood pressure or high cholesterol, that increase their chances of having a heart attack or a stroke.  Learn more below:

Wellcare-By-Fidelis-Care-Stethoscope-and-Heart

What is the connection between diabetes and heart disease?
  • High blood glucose from diabetes can damage your blood vessels and the nerves that control your heart and blood vessels. Over time, this damage can potentially lead to heart disease.

  • People with diabetes also tend to develop heart disease at a younger age than people without diabetes. In fact, adults with diabetes are nearly twice as likely to have heart disease or stroke as adults without diabetes.

  • The good news is that the steps you take to control your diabetes also help lower your chances of developing heart disease.
What other factors increase my chances of heart disease if I have diabetes?
  • Smoking ➤ Smoking raises your risk of developing heart disease.  If you have diabetes, it is important to stop smoking, because both smoking and diabetes narrow blood vessels.  

  • High blood pressure ➤ If you have high blood pressure, your heart has to pump harder to circulate blood. High blood pressure can strain your heart, damage blood vessels, and increase your risk of heart attack and stroke. Consider having your blood pressure checked regularly, and work with your doctor to regulate or lower high blood pressure.

  • Harmful cholesterol levels ➤ Cholesterol is a type of fat produced by your liver. You have two kinds of cholesterol in your blood: LDL and HDL. LDL, often referred to as “bad” cholesterol, can build up and clog your blood vessels. HDL, sometimes referred to as the “good cholesterol.” Higher levels of HDL is linked to lower risk for heart disease and stroke. To improve LDL and HDL balance, try to limit the amount of fat in your eating plan, consume more plant-based foods, and get regular physical activity.

  • Family history of heart disease ➤ Unfortunately, a family history of heart disease may add to your chances of developing the condition. If one or more of your family members had a heart attack before the age of 50, you have double the chance of developing heart disease, compared with diabetics who have no family history of the disease.  


Testing for Diabetes

Common Tests to Determine and Monitor Type 1 Diabetes, Type 2 Diabetes, and Prediabetes

If diagnosed, your doctor will have you take one or more of the following blood tests:

A1C Test

The A1C test measures your average blood sugar level over the past 2 or 3 months.  

  • An A1C below 5.7% is normal
  • An A1C between 5.7 and 6.4% indicates you have prediabetes
  • An A1C 6.5% or higher indicates you have diabetes

*Results for gestational diabetes can differ. Ask your health care provider what your results mean if you’re being tested for gestational diabetes.

Glucose Tolerance Test

This test measures your blood sugar before and after you drink a liquid that contains glucose. You’ll be asked to fast overnight before the test and have your blood drawn to determine your fasting blood sugar level. Then you’ll drink the liquid and have your blood sugar level checked 1 hour, 2 hours, and possibly 3 hours afterward. 

At 2 hours, a blood sugar level of.... 

  • 140 mg/dL or lower is considered normal
  • 140 to 199 mg/dL indicates you have prediabetes
  • 200 mg/dL or higher indicates you have diabetes

*Results for gestational diabetes can differ. Ask your health care provider what your results mean if you’re being tested for gestational diabetes.

Fasting Blood Sugar Test

This test measures your blood sugar after an overnight fast. 

A fasting blood sugar level of...

  • 99 mg/dL or lower is normal
  • 100 to 125 mg/dL indicates you have prediabetes
  • 126 mg/dL or higher indicates you have diabetes

*Results for gestational diabetes can differ. Ask your health care provider what your results mean if you’re being tested for gestational diabetes.

Random Blood Sugar Test

This measures your blood sugar at the time you’re tested. You can take this test at any time and don’t need to fast prior to your appointment. A blood sugar level of 200 mg/dL or higher indicates you have diabetes.

*Results for gestational diabetes can differ. Ask your health care provider what your results mean if you’re being tested for gestational diabetes.

What Does Insulin Do?

Insulin allows the cells in the muscles, fat and liver to absorb glucose that is in the blood. The glucose serves as energy to these cells, or it can be converted into fat when needed. Insulin also affects other metabolic processes, such as the breakdown of fat or protein.  Learn more below:

How is insulin created?

Insulin is a hormone created by your pancreas that regulates the amount of glucose in your bloodstream at any given moment. It also helps store glucose in your liver, fat, and muscles. In addition, insulin balances your body’s metabolism of carbohydrates, fats, and proteins.

What happens with insulin when you eat?

When you eat, your blood glucose levels elevate, and this leads a typical person’s pancreas to release insulin, so that the sugar can be stored as energy for later use. Without this pancreatic ability, as a person with either type 1 diabetes or advanced type 2 diabetes, one's blood sugar levels may rise dangerously high, or drop too low.

What happens when insulin no longer works?

Without proper insulin function, your body can’t store glucose in your muscles or liver, but neither can it make any fat.  Instead, the fat breaks down and produces, among other things, keto acids.  If the acid levels grow too high, the imbalance can trigger diabetic ketoacidosis, a potentially fatal condition if not treated immediately.

Know the Signs: Colorectal Cancer Is Increasing in Younger Adults
3/4/2026 • Posted by Sharon McLaughlin, MD, FACS in Health and Wellness

Colorectal Cancer image

For many years, doctors believed colorectal cancer — cancer of the colon or rectum — mostly affected older adults. That idea is changing fast.

In the United States, colon cancer is rising in people under age 50. At the same time, it is going down in people over 50. Why? Because more older adults are getting screened. Doctors can find and remove small growths before they turn into cancer.

Why Colon Cancer Is Often Missed in Young People

Here’s one of the most important, and frustrating, parts of the problem.

When a 70-year-old has belly pain or rectal bleeding, doctors quickly think about cancer. But when a 25-year-old has the same symptoms, they may be told it is stress, hemorrhoids, or a stomach bug.

Because of this, young people are often diagnosed later, when the cancer is harder to treat.

Warning Signs Young People Should NOT Ignore

Young people do not need to panic, but they do need to pay attention to their body. Colon cancer in young adults often causes symptoms. If you or a loved one is experiencing anything on the list below, tell a doctor.

Symptoms that should prompt a medical visit:

  • Blood in the stool or on toilet paper
  • Diarrhea or constipation that lasts more than a few weeks
  • Stool that looks thinner than usual
  • Ongoing belly pain or cramping
  • Unexplained weight loss
  • Feeling very tired

Red flags that may warrant screening before age 45:

  • Symptoms that do not improve
  • A family history of colon cancer or large polyps
  • Crohn’s disease or ulcerative colitis
  • Unexplained low iron levels

No one should ignore these symptoms just because they are young.

Why Are Colon Cancer Rates Rising for Young People?

Many people eat more fast food, sugary drinks, and packaged snacks. These foods are low in fiber. Fiber works like a broom in our body. It helps move waste out of the colon. When we do not get enough fiber, waste stays in the colon longer. Over time, this can irritate the bowel and may raise the risk of cancer.

Another clue is the tiny bacteria that live in our gut. This group of bacteria is called the gut microbiome. Most of these bacteria help keep us healthy. But some harmful bacteria can damage cells in the colon.

Less movement may also play a role. Many of us sit for long hours at school, work, or home. Not moving enough can lead to weight gain and long-term inflammation. Inflammation is like a slow, hidden fire inside the body. Over time, it can make it easier for cancer to grow.

What Can We Do?

  • Eat the rainbow: Fruits, vegetables, beans, and whole grains give us fiber.
  • Move regularly: Walking, sports, dancing, our gut loves movement.
  • Speak up: If something feels wrong, tell a trusted adult or healthcare provider.
  • Trust persistence: If symptoms continue, keep asking questions.

Get Screened

Colon cancer is one of the most preventable cancers, but only if we find it early. Most people should start screening at age 45. If you’re younger and experiencing symptoms of colorectal cancer, talk to your doctor.

Screening options include:

  • Colonoscopy (the gold standard): A doctor looks at the whole colon and can remove polyps before they turn into cancer.
  • Cologuard: A non‑invasive, at‑home stool test that looks for hidden blood or anything wrong with DNA. It’s usually done every 1–3 years. If anything concerning comes back in the results, a colonoscopy is needed.

The most important message is this: The best screening test is the one you do.

If you or a loved one has symptoms or risk factors, talk to a doctor. Listening to your body could save your life.
