Pre-existing Diabetes and Auto-Immune Flashcards
Define: Type 1 diabetes mellitus
Also called
- Insulin dependent diabetes or
- Juvenile diabetes.
- Autoimmune destruction of insulin-producing (beta cells) of the pancreas
- Results in total insulin deficiency.
Explain: How Insulin works after a meal
- digestion breaks down carbs into sugar molecules inc. glucose/aminoacids
- glucose/aminoacids are absorbed into the blood stream- BGL rise quickly
- rise in BGL trigger beta cells in pancreas to secrete insulin which moves into the blood stream
- Insulin enables glucose to enter the cells in the body particularly the muscle and liver cells
- Here insulin and other hormones determine whether glucose will be burned for energy or stored for future use
List causes of Type 1 DM
Autoimmune disease Genetic (10% chance of aquiring from a direct relative) Environmental factors (e.g. viral infection)
List symptoms of Type 1 DM
Hyperglycemia Polyuria Polydipsia Lipidemia Polyphagia Glycosuria Ketoacidoses Ketouria Macular degeneration
How is Diabetes diagnosed
Fasting or Random <5.5: diabetes unlikely
Fasting 5.5-6.9 OR Random 5.5-11.0: Diabetes uncertain- Oral GTT
Fasting >7.0 OR Random >11.1: Diabetes likely
Describe: Treatment for Type 1 DM
Can deliver Insulin fast, regular, intermediate or slow
Insulin Pump
- catheter directly into abdominal skin
- delivers insulin directly into the system
- controlled by a small digital device that is programmed with the correct doses
What are complications/outcomes of Type 1 diabetes
Heart disease Renal disease Retinopathy Vascular disease Neuropathy Thyroid disease
Fertility: Decreased fertility (recurrent yeast infections, decreased lubrication, painful sex) Delayed menarche (menstruation) Premature menopause Male effects
What are the effects of Type 1 Diabetes on pregnancy
Miscarriage Congenital abnormality (brain and neural tube defects, cardiac defects, ambiguous genitalia) SGA Preterm birth Preeclampsia, Perinatal mortality, LGA Key – tight blood sugar control before conception and throughout pregnancy
Explain: Diabetes in pregnancy
In pregnancy the woman’s body uses glucose for energy and growth of the fetus
- its production is controlled and regulated by the hormone insulin
- Insulin production increases in pregnancy to manage rising glucose levels and is a normal physiological response to growing a baby and supplying enough energy as well
- when a pregnant woman’s body is less receptive to the regulating effects of insulin it struggles to control the amount of glucose within the blood stream
- which leads to increased glucose levels
This process is intensified when a woman has diabetes prior to pregnancy and increases insulin resistance
Explain: Treatment/Management of diabetes in pregnancy
- Pre-conception counselling
- Regulation of HbA1c – good long term glucose control
Pregnancy
- Medical r/v after booking in
- Regular monitoring
- Multi-disciplinary management
- Growth u/s
Labour/Birth
- Delivery plan
- CTG
- Pead if needed
Postnatal
- Check for neonatal hypoglycaemia
- r/v insulin regimne
- BF safe
Define: Type 2 Diabetes
Adult onset
- Hyperglyaceamia
- Insulin deficiency
- Insulin resistance
- Innapropriate or excessive glucagon
Family history plays a role in this type of diabetes
List risk factors/ causes of Type 2 DM
>45 years of age, Overweight/obese Hypertensive Cardiovascular disease Had GDM
List symptoms of Type 2 diabetes
Polyuria- production of abnormally large volumes of dilute urine
Polydypsia- abnormally great thirst
Polyphagia- excessive hunger or increased appetite and is one of the 3 main signs of diabetes
Weight loss
Recurrent yeast infections
Recurrent UTI
Blurred vision
What are the complications/outcomes of Type 2 diabetes
Blindness (retinopathy) Kidney disease Nerve damage Amputation Cadiovascular disease: stroke, heart attack, loss of circulation in arms and legs
Fertility:
- Links with PCOS
- Alterations to the menstrual cycle
- Anovulatory cycles
- Poor quality blastocysts
- Increased c reactive protein
Describe: Treatment/Management of Type 2 DM in Pregnancy
In General: Lifestyle modification Weight loss Exercise Oral hypoglycaemics Insulin
Pregnancy
- HbAic
- Physical examination
- BGL monitoring and ongoing strategy
- Medical and diabetic r/v
- U/S
- Growth u/s
Labour/Birth
- BGL monitoring
- diabetes managment
- CTG
- Paed available if needed
What are the pregnancy complications of Type 2 diabetes
Miscarriage Cogential malformations IUGR Macrosomia Polyhydraminos FDIU
Define: Hypothyroidism
Hypothyroidism comprises a lack of thyroid hormones, thyroxine (T4) and tri-iodothyronine (T3).
List symptoms of Hypothyroidism
Weight gain Constipation Cold intolerance Alopecia Dry skin Hoarseness Lethargy Ataxia Cognitive impairment Bradycardia
Explain: Treatment/Management of Hypothyroidism in Pregnancy
Pregnancy
- treatment immediately upon diagnosis
- if TSH rises: adjust Thyroxine dose
- Check fT4 and TSH at booking and 4-6wkly throughout pregnancy
Labour/Birth
- Treat as normal
Postnatal
- r/v Thyroxine dose
- Neonatal screening required
- BF safe
- Ch fT4 nad TSH 6wks postpartum
Define: Thyrotoxicosis
is the clinical syndrome caused by high serum concentrations of thyroid hormones.
Typically caused by Graves disease: an autoimmune condition in which thyrotoxicosis is caused by autoantibodies to the thyroid stimulating hormone receptor (TSHR).
List signs and symptoms of Thyrotoxicosis
- Heat intolerance
- Weight loss (despite good appetite)
- Insomnia
- Agitation
- Tremor
- Retraction of the upper eyelid
- Sweating
- Tachycardia and bounding pulse
- Diarrhoea
- Oligo- or amenorrhoea
Complications of Thyrotoxicosis
Graves ophthalmopathy
Graves dermopathy
Explain: Treatment/Management of Thyrotoxicosis in pregnancy
Pregnancy
- Thyrotoxicosis- increased risk of miscarriage. Diagnosis difficult as symptoms mimicl pregnancy
- Graves disease improves
- U/S
- blood tests
Labour/Birth
- High risk medical management
- Continuous fetal monitoring (fetal tachycardia)
- Paed notified once established
Postnatal
- neonate r/v: may required antithyroid medication
- Encourage BF
- Maternal thyroid hormone levels rechecked at 6wks
Define: Systemic Lupus Erythematosus (SLE)
With lupus erythematosus, the body produces autoantibodies against its own connective tissue.
(SLE): the most common variation of lupus affecting the entire body including serous membrane, kidneys, joints, and skin
List signs and symptoms of Systemic Lupus Erythematosus (SLE)
Classic ‘butterfly rash’ (malar rash) on cheeks Weight loss Fatigue and headaches Fever with flu-like symptoms Arthralgia (joint pain without swelling)

Acute and chronic infection
Nausea, vomiting and diarrhoea
Alopecia (hair loss) Photosensitivity Arthritis and sometimes early morning stiffness
and others…
Explain: Treatment/Management of Systemic Lupus Erythematosus (SLE)
Pregnancy
- Pregnancy complications are generally reduced if the lupus is mild or stable, particularly at conception
- multidisciplinary care
- Full antenatal bloods for baseline
- record medical history and medications
- Medical r/v
Labour/Birth
- High risk management

- Teds for LSCS
- Continuous EFM
Postnatal
- increased risk of lupus flare up
- prompt return to maternal drug regimen
