1
Q

What is Diabetes?

A

High blood sugar levels

2
Q

What is insulin?

A

Hormone made in the beta cells of the pancreas that allows glucose to enter cells

3
Q

How are glucose levels regulated in someone without Diabetes?

A

The pancreas detects when glucose enters the blood and releases the correct amount of insulin to allow glucose to enter cells

4
Q

What is Type I Diabetes?

A

Pancreas doesn’t make insulin or the beta cells of the pancreas are destroyed

5
Q

What is Type II Diabetes?

A

Insulin is not effective or the pancreas doesn’t produce enough insulin to counteract the levels of glucose

6
Q

What is Gestational Diabetes?

A

Placenta-induced insulin resistance with onset or first recognition during pregnancy

7
Q

What are the common symptoms of Diabetes?

A
  • Increased urine output
  • Thirst
  • Lethargy
  • Weight loss/gain
  • Affects heart, eyes and kidneys
8
Q

How does Diabetes affect the heart?

A

High BP and insulin resistance increase the risk of coronary heart disease

9
Q

A

Increased risk of retinopathy, cataracts and glaucoma

10
Q

How does Diabetes affect the kidneys?

A

Increased risk of nephropathy

11
Q

What are the neonatal risks associated with Diabetes in pregnancy?

A
  • Stillbirth
  • Neonatal death
  • Congenital abnormality
  • Prematurity

12
Q

What are the maternal risks associated with Diabetes in pregnancy?

A
  • Ketoacidosis
  • PET
  • Miscarriage
  • Polyhydramnios
  • Shoulder dystocia
13
Q

Why is there an increased risk of macrosomia?

A

Lack of insulin results in excess glucose which is passed to the baby

14
Q

What is a normal glucose level?

A

Before breakfast = <5.2

1 hour after each meal = <7.8

15
Q

What is the glycaemic index?

A

How fast or slow food is digested

16
Q

How can the glycaemic index be reduced?

A
  • Reduce sugar intake (e.g. artificial sweetener in tea, no chocolate or sweets)
  • Avoid saturated fats (e.g. cream, butter)

  • Previous baby >4.5kg
  • Previous GDM
  • FH of Diabetes
  • PCOS
22
Q

When does a Glucose Tolerance Test take place?

A

At booking and with 27/40 bloods (or if arises in pregnancy, just at 27/40 bloods)

23
Q

How does the GTT work?

A
  1. Fast for 12 hours
  2. Blood test on arrival
  3. Drink glucose solution
  4. Wait 2 hours
  5. Repeat blood test
24
Q

What values indicate GDM?

A

Fasting = >5.6

After glucose = >7.8

25
Q

What additional testing can be done?

A
  • HbA1c is glucose bound to Hb that has become glycosylated
  • Testing these levels show the average glucose level over the past 2-3 months
  • Results should be <48
26
Q

How is Diabetes in pregnancy managed?

A
  • Diabetic clinic
  • Blood sugar monitoring
  • USS every 4 weeks from 28/40
  • Dietary advice
  • Medication if required

Q

How often should blood sugar be monitored?

A
  • Before breakfast

- 1 hour after every meal

28

  • Metformin

- Insulin

29
Q

  • Once blood glucose >4 give starchy carbohydrate (e.g. digestive biscuits)
33
Q
