Is it obligatory for the family of a girl afflicted with diabetes to inform the suitor of her illness before the marriage contract, even if he does not ask, knowing that the disease is not contagious and not harmful to the husband?

Any defect that causes aversion between spouses, or that frustrates the purpose of marriage, such as enjoyment and procreation, necessitates the option (of annulment). Diabetes falls under these defects, as its severity varies and its effects may include enjoyment, and it may cause fetal death or deformities, in addition to requiring special care and financial cost. Therefore, the suitor must be informed of his fiancée's illness before marriage.
