In a healthy person, sugar (glucose) enters the bloodstream within minutes of eating, peaks around 60-90 minutes, and typically returns to pre-meal levels within two to three hours, as insulin moves it into cells for energy or storage. For people with diabetes or insulin resistance, this process is slower, taking longer to return to normal, and depends heavily on insulin production, activity levels, and meal composition.
Sugar withdrawal generally lasts anywhere from a few days to a few weeks. Each person will go through the withdrawal process differently, and the intensity of symptoms will depend on whether you fully cut out sugar or slowly wean off it.
Your body starts processing sugar within minutes of eating, and it usually peaks in the blood around 60 minutes, returning to baseline in two to three hours for most healthy individuals.

If you're at high risk but your test results are normal, your doctor might test you again later in your pregnancy to make sure you still don't have it.
Sugar in your blood (glucose) can cross the placenta to your baby during pregnancy, but insulin does not. The placenta is an organ attached to the lining of the womb. It delivers oxygen and food to your growing baby. Your baby stores the extra sugar and may grow more quickly than the baby of someone without diabetes.
Most cases are only discovered when your blood sugar levels are tested during screening for gestational diabetes. Some women may develop symptoms if their blood sugar levels gets too high (hyperglycaemia), such as: increased thirst. needing to pee more often than usual.

To know if you have diabetes, look for symptoms like increased thirst/urination, extreme tiredness, blurry vision, slow-healing sores, and numbness/tingling in hands/feet, but remember many with Type 2 have few or no symptoms; only a doctor can diagnose diabetes with blood tests (like HbA1c, fasting glucose) to check blood sugar levels, as finger pricks aren't for diagnosis.
The best diet for diabetics focuses on whole foods like vegetables, fruits, whole grains, lean proteins, and healthy fats, emphasizing portion control and consistent meal times to manage blood sugar. Key strategies include filling half your plate with non-starchy vegetables, choosing high-fiber carbs (like legumes, brown rice, quinoa), incorporating fatty fish and olive oil, and limiting added sugars, unhealthy fats, and refined carbs (like pastries, sugary drinks). Popular approaches like the Mediterranean diet and DASH diet, rich in nutrients and low in processed items, also work well for diabetes management.
