To clarify the influence of diseases with hormonal disturbance on puerperal lactation, we studied the milk amounts of milk obtained by suckling and manual extraction during the first 6 days after delivery and the rate of breast-feeding in 40 patients with diabetes mellitus, 40 with hyperthyroidism, 28 with hypothyroidism and 57 with ovulatory disturbance, and in 40 healthy women. The mean body weight of the patients with diabetes mellitus was 7 kg more than those in other groups, and delivery occurred one gestational week earlier than in other groups. The amounts of suckled milk produced by patients with diabetes mellitus and hypothyroidism were significantly (p < 0.05) less than those in other groups; there was no significant difference in milk productions in the other groups. One month after delivery, 35.5% of the babies in the diabetic group were receiving complete breast-feeding, which was significantly (p < 0.05) lower than the percentages (52-55%) in the other groups. These data suggest that neonatal suckled milk volume in diabetic women is decreased, and that hypothyroidism may influence the initiation of lactation even when the patients are euthyroid due to treatment. © 1989.
