"Married at 20. Has 7 children. Another died at 4 1/2 months from heart failure. "She complains that about six times in the past two years she has had attacks of vomiting lasting days, followed by diarrhoea -- the whole thing on occasions lasting four to five weeks. During this time she eats and sleeps poorly and is lacking in energy. In view of her good personality - efficient housewife with seven children and outside interests, one hesitates to label the condition as neurotic. Like Dr M I could find no precipitating factor. She tells me that her feet swelled during her pregnancies. I wonder if Dr M would consider it worth while doing a blood urea and other tests of kidney function during the next attack in case of possible uraemia?"."
