[Effect of drinking mineral water on hormonal regulation of glucose homeostasis after mastectomy for breast cancer].

Glycohomeostasis was studied in patients operated for breast cancer, healthy controls and ulcer patients before and after gastric resection (each group consisted of 12-15 examinees). Patients with duodenal ulcer had insulin hypersection including early phase reaction. Gastric resection decreases insulinemia in an early phase of reaction to oral glucose test. In postmastectomy patients insulinemia is 2-3 times higher than that in duodenal ulcer patients and 5 times higher than that in healthy subjects. Besides hyperinsulinemia, they had insulin resistance and impaired carbohydrate tolerance. A course intake of mineral water raised tissue sensitivity to insulin at early stages of glucose test and lowered basal level of insulin and hydrocortisone.
