Diabetes screening means a simple blood test that checks your sugar level before you feel unwell. The three common tests are the fasting blood sugar test, the HbA1c (A1C) test and the oral glucose tolerance test (OGTT). Type 2 diabetes often causes no early symptoms, so testing is the only sure way to know.
This guide covers who should ask for a test, what the numbers mean, why PCOS and diabetes in pregnancy matter, and what you can do to lower your risk.
Why women should think about screening
WHO explains that type 2 diabetes can be mild and take years to show, so it is often found late, when damage to the heart, eyes, kidneys, nerves or feet has already started. More than 95% of people with diabetes have type 2. Finding it early, or finding prediabetes, gives you time to act.
Women have some extra reasons to be checked. PCOS and diabetes in pregnancy both raise the chance of diabetes later, as explained below.
Risk factors
The CDC lists these risk factors for prediabetes and type 2 diabetes:
- Being overweight or having obesity
- Age 45 or older
- A parent or sibling with type 2 diabetes
- Being active fewer than three times a week
- Fatty liver disease (non-alcoholic)
- Diabetes during a past pregnancy, or having a baby weighing more than 9 pounds (about 4 kg)
- Having prediabetes already
The NHS adds that people with a South Asian background are advised to get checked from an earlier age, over 25, than White people, for whom the age is over 40. High blood pressure also adds to risk. If you are of Indian origin and have any of these factors, ask your doctor about testing even if you feel well.
Symptoms to watch for
Some women have none. When symptoms appear, the NHS and WHO list:
- Feeling very tired
- Needing to urinate more often, especially at night
- Constant thirst
- Unplanned weight loss
- Blurred vision
- Cuts or wounds that heal slowly
- Itching around the genitals or repeated thrush
Tip: Keep a short note of your symptoms and your family history before the visit. Doctors find it much easier to decide which test is right when they have these details.
The tests explained
The CDC gives these cut-offs. Labs and doctors may confirm a result by repeating a test, and results are always read together with your overall health.
- HbA1c (A1C): reflects your average blood sugar over the past 2 to 3 months. Normal is below 5.7%, prediabetes is 5.7 to 6.4%, and diabetes is 6.5% or higher.
- Fasting blood sugar: measured after an overnight fast. Normal is 99 mg/dL or below, prediabetes is 100 to 125 mg/dL, and diabetes is 126 mg/dL or above.
- OGTT: blood is taken after fasting, then after you drink a sugary liquid, with another reading at 2 hours. A 2-hour value below 140 mg/dL is normal, 140 to 199 mg/dL is prediabetes, and 200 mg/dL or above is diabetes.
The CDC also advises anyone who had a sugar check at a health camp or pharmacy to follow up with a doctor, who may repeat the test. A single high reading is a reason to check again, not a final answer.
PCOS, pregnancy and diabetes
PCOS
The NHS says polycystic ovary syndrome can raise the risk of type 2 diabetes, along with high blood pressure, heart disease and fatty liver. If you have PCOS, regular check-ups are sensible. Healthy eating, exercise and, if you are overweight, weight loss are the NHS-advised first steps. Our guide to PCOS symptoms, causes and treatment explains more.
Gestational diabetes
Gestational diabetes appears during pregnancy and is found through routine screening rather than symptoms, according to WHO. It raises the chance of problems in pregnancy and delivery, and the mother, and possibly the child, have a higher risk of type 2 diabetes later. If you had it before, ask for a blood sugar test after delivery and again at regular intervals. Read gestational diabetes symptoms, diet and care for the pregnancy side.
How to lower your risk
WHO says lifestyle change is the most effective way to prevent or delay type 2 diabetes.
- Aim for at least 150 minutes of moderate activity a week, such as brisk walking, cycling or yoga that raises your heart rate.
- Eat a balanced diet and cut back on sugar and saturated fat, for example sweets, fried snacks and sugary drinks.
- Keep a healthy weight, and ask your doctor what that means for you.
- Avoid tobacco.
- Attend regular check-ups and blood tests.
A simple routine helps: pick a fixed date once a year, such as your birthday, to ask about a blood sugar check, blood pressure and weight. Small, steady habits work better than short crash diets, and the whole family can join in with walks and home-cooked meals.
When to see a doctor
Book a visit for a blood test if you have the symptoms above, a strong family history, PCOS, past gestational diabetes or other risk factors.
When to be cautious: Go to hospital urgently if you have extreme thirst and frequent urination together with vomiting, stomach pain, fast breathing, confusion or extreme drowsiness. Do not wait for an appointment.
What to expect at the doctor
The doctor will ask about symptoms, family history, weight and previous pregnancies, and may check your blood pressure and weight. You may be asked to fast for some tests, so ask beforehand. Pregnant women usually have sugar tests as part of routine antenatal check-ups. If a result is in the prediabetes range, the usual plan is lifestyle change and repeat testing.
