Patho:
• Any degree of glucose intolerance with its onset during pregnancy
• Pregnancy hormones decrease fasting glucose levels, increase fat deposition and increase appetite.
• Postprandial glucose concentrations increase as insulin resistance increases

Q

Explain the physiology of normal menstrual cycle. Normal menstrual loss?

A

Days 1-14 - follicular phase - FSH high and stimulates egg. Oestrogen produced by developing follicles

Day 14 - ovulation - egg released

Day 14-28 - luteal phase - Ruptured follicle forms corpus luteum and secretes prog and oestrogen.

Day 28 - menses - Corpus luteum degrades. Loss of oestrogen and prog causes necrosis of endometrium. Normal blood loss 20-60 mls. 80+ menorrhagia
