And it gets even worse for every month when she should get her menstruation. Diabetic teenagers often are very challenging in terms of glucose control. The wide fluctuations in your daughter's blood glucose values may be a function of diet, activity, type of insulin and timing of insulin injections.
Irregular menstruation is common in young women and most likely reflects irregular ovulation.
If glucose control becomes a problem during menses, then your daughter's physicians might consider starting your daughter on birth control pills specifically to regulate the hormonal activity of the ovaries. I would suggest a low estrogen type pill and you could consult your physician about specific brand names. This is an injection given every three months. The progesterone will suppress ovulation, however women often complain of irregular bleeding when they first start treatment. Neither medication will affect future childbearing.
