Type 2 Diabetes

Medically reviewed by [Clinician name, credentials] on [date]

Type 2 diabetes is very common. The CDC says about 1 in 8 Americans has diabetes, and most of them have type 2. It can feel overwhelming at first, but it's very manageable with a good plan and steady support. Here's a plain-language guide.

This page is for general education. It isn't a diagnosis and doesn't replace a visit with a clinician.

What is type 2 diabetes?

Your body turns food into glucose (sugar) for energy. A hormone called insulin acts like a key that lets glucose into your cells. With type 2 diabetes, your cells don't respond to insulin the way they should. This is called insulin resistance. Over time, your pancreas can't keep up, and blood sugar rises.

High blood sugar over months and years can damage the body. It can lead to heart disease, vision loss, and kidney disease. Keeping blood sugar, blood pressure, and cholesterol near your targets helps lower those risks.

Prediabetes means blood sugar is higher than normal but not high enough to be diabetes. The CDC says type 2 diabetes can often be prevented or delayed with lifestyle changes like losing weight if needed, eating well, and staying active.

Higher risk includes having prediabetes, extra weight, age 45 or older, a parent or sibling with type 2 diabetes, being active less than 3 times a week, or a history of diabetes during pregnancy.

Common symptoms

Many people have no symptoms, or symptoms so mild they go unnoticed for years. When symptoms happen, they can include:

Feeling very thirsty and peeing more often
Feeling hungrier than usual
Feeling tired
Blurry vision
Numbness or tingling in the hands or feet
Cuts or sores that heal slowly
Losing weight without trying
Frequent urinary tract or yeast infections
Dark, velvety patches of skin on the neck or armpits

Diabetes is diagnosed with blood tests, such as an A1C (your average blood sugar over about 3 months) or a fasting glucose test. The USPSTF notes that a diagnosis should be confirmed with repeat testing.

When telehealth works — and when you need in-person care

Telehealth often works well for:

Reviewing home glucose readings or continuous glucose monitor reports
Going over lab results and what they mean
Medicine check-ins, side effects, and refills
Building an eating, activity, and weight plan you can stick with
Regular follow-up between lab draws

You'll need in-person care or a lab for:

Blood tests like A1C, kidney function, and cholesterol
Foot exams, especially if you have numbness or sores
Eye exams with an eye doctor, on the schedule your clinician recommends
Any wound that's red, swollen, draining, or not healing

How Oceanside Health can help

Video visits to understand your history, goals, and daily routine.
Lab orders and results review. We'll explain your numbers in plain words. [CONFIRM: lab partner(s) and how orders work]
Home monitoring support. If you check your blood sugar at home, we can review the readings at your visits. Readings can be shared through our secure patient system. [CONFIRM: supported meters/CGMs]
A plan built with you. That includes healthy eating, activity, weight, and, when needed, medicine. CDC and MedlinePlus both stress that lifestyle stays important even if you take medicine.
Steady follow-up so small problems get caught early. We also help with blood pressure and cholesterol, which matter a lot with diabetes.
Referrals to eye doctors, podiatrists, diabetes educators, or specialists when needed.

We see patients by video across Brevard County. [CONFIRM: in-person availability]

Call 911 or go to the ER if…

Call 911 or go to the ER if you or a family member with diabetes has:

Trouble breathing, or deep, fast breathing
Fruity-smelling breath
Nausea and vomiting, especially with high blood sugar
Confusion, being hard to wake, or decreased alertness
Passing out, or a low blood sugar that the person can't treat on their own

Low blood sugar (usually below 70 mg/dL) can quickly become dangerous, especially for people who take insulin or certain diabetes pills. The American Diabetes Association says not to hesitate to call 911. If someone is unconscious and glucagon isn't available, call 911 right away.

Also call 911 for chest pain or pressure, or stroke signs: sudden face drooping, arm weakness, or trouble speaking.

Frequently asked questions

Can type 2 diabetes go away?

Type 2 diabetes is usually a long-term condition. Many people can manage it well, and some reach normal blood sugar with lifestyle changes or medicine. Your clinician can tell you what's realistic for you.

Who should get tested?

The USPSTF recommends screening adults ages 35 to 70 who have overweight or obesity. Some people should be tested earlier, based on family history and other risk factors. Ask your clinician.

What is a "normal" A1C?

Per the USPSTF, an A1C of 6.5% or higher is consistent with diabetes, and 5.7% to 6.4% is consistent with prediabetes. Your personal target may be different. Your clinician will set it with you.

If I take medicine, do I still need to change my diet?

Yes. The CDC says you'll still need to eat healthy and stay active, even if you take insulin or other medicines.

I got a high sugar reading at a pharmacy or health fair. Now what?

The CDC recommends following up with a clinic or doctor's office to make sure the results are accurate.
