Give two reasons why pregnant women are at risk of oesophagitis |
• Increased progesterone leads to loss of tone of LOS, which can easily lead to backflow of acid. • Increased gastrin levels leads to increased acid production. |
|
Why are women at an increased risk of DVT during pregnancy? |
Due to increased production of fibrinogen and clotting factors which leads to a hypercoagulable state. |
|
Why might a pregnant lady complain of swollen ankles? Explain the physiology. |
Due to increased release of fluid from capillaries as a result of reduced oncotic pressure due to reduction in albumin. |
|
A woman is being investigated for gallstones during the third trimester of her pregnancy. Which liver marker will not be helpful in deciding her diagnosis and why? |
ALP because this is usually raised in pregnancy |
|
When assessing the thyroid function in pregnant women, why would you only use the free T3 and T4 levels (and not total T3 and T4)? |
Because thyroid binding globulin levels are increased during pregnancy (due to effect of oestrogen). So total T3 and T4 levels would also be increased so are not a reliable indicator of thyroid status. The free T3 and T4 levels remain unaffected so can be used. |
|
Give two changes that occur to the constituents of blood during pregnancy. |
• haemoglobin levels reduced due to haemodilution • Red blood cells increase in size • Haematocrit levels are reduced • Reticulocyte levels are increased? |
