Astrologer: I will frequently sick, but not to die

We are not that a big fan of astrologer, but our parents does. At least, we need them for date selection. We pay once right? so we need to ask everything to worth the money. Of course, we do not satisfy with Monday for marriage as we feel a bit odd after a weekend. We ask for next year, However astrologer does not have next year calendar, so he can choose one for us. Instead, we asked for an expected life after marriage. He told that "Luyna" will becomes more frequent sick after marriage and of course Lyda might get fatter. It seems unfair prediction. It seems marriage brought be diseases!? But we are sure about diseases. Still remember a big relief after blood test. So what are the reasons behind that I ponder.
