Dear @Imanileigh – this is one of the most personal and weighty decisions a woman can make in her life. There are many, many factors to consider – I am sure also in your case – that go far beyond the presence of T1D as part of the picture. For that aspect, I would refer you to our specialized sub-forum on pregnancy and diabetes here: https://forum.tudiabetes.org/c/diabetes-and-pregnancy. You can browse through all kinds of stories, which, while maybe not fully representative, will give you realistic ideas of some of the typical things you can expect.
Yes, there are increased risks both during pregnancy and after, but you need to consider them all in perspective. (And especially with the help of a medical team you trust, so it’s very good that you immediately set up all those important appointments.)
[Here I am specifically going to open a big parentheses to comment on one of the responses above, regarding drawing a straight line from “I have T1D --> I am not going to have children since I would be exposing them to the risk of having T1D.” First, while the incidence of offspring with T1D from diabetic parents does indeed increase compared to offspring of the non-diabetic population, it is still ultimately a very low risk on average. Second, the majority of T1D diagnoses are of people who do not have other known cases of T1D in their families. Third, the risk that a diabetic mother will pass on the condition is significantly lower than that of a diabetic father.
While the exact numbers are not settled (there simply are too many other factors that impact the prevalence of genetic transmission, let alone whether the predisposition develops into the disease), here are a couple of helpful snippets:
A. “Just who is at risk for developing type 1 diabetes? Here’s a sampling of what Dr. Warram, a Lecturer in Epidemiology at Harvard School of Public Health, said is known: The risk for a child of a parent with type 1 diabetes is lower if it is the mother — rather than the father — who has diabetes. ‘If the father has it, the risk is about 1 in 10 (10 percent) that his child will develop type 1 diabetes — the same as the risk to a sibling of an affected child,’ Dr. Warram says. On the other hand, if the mother has type 1 diabetes and is age 25 or younger when the child is born, the risk is reduced to 1 in 25 (4 percent) and if the mother is over age 25, the risk drops to 1 in 100 — virtually the same as the average American.”
He goes on to assess how these numbers should or shouldn’t be interpreted when a person is making the decision whether to bring a child into this world: “To be told a child has a 4 percent or 10 percent risk of diabetes sounds very absolute and scientific,” he says. "But a myriad other things can go wrong with a child — medically and socially — and these risks cannot be measured precisely. Also, there are a myriad other things that can go right for a child. Even if a child does develop diabetes, it needn’t prevent him or her from finding success and happiness in life. Raising children — whether they are your own or adopted — is an experience involving risks of great rewards and risks of great costs that can’t really be known in advance. If a number can be attached to one of those risks, should it weigh more than the others?"
B. "By 20 years of age, 5–8% of the offspring of diabetic men and only 2–5% of the offspring of diabetic women have been found to be affected."
(Obviously this is just one study on the topic, and limited to the population on Finland, which happens to have a fairly high incidence of T1D, but it does include a very good set of references to earlier studies exploring the same question. So I’d specifically recommend looking at the citations 1-8 in the bibliography at the end as well.)]
If you do decide to have a child, there are things we know improve the odds of a healthy pregnancy and healthy baby: tight BG control, taking a large supplemental dose of folic acid and vitamin D (in addition to the general prenatal vitamin you should be taking), staying hydrated, keeping up reasonable levels of physical activity, not putting on more than the recommended for you weight, going for all your extra monitoring visits, minimizing stress.
Bottom line, I think anyone asking themselves this question should answer another one first: am I in a position to be the kind of parent I would describe as a good parent for this child? It’s a big question and a “yes” or a “no” can be predicated on an infinite variety of combinations of factors, but its answer is the only thing that matters when a human being is born.
