Is extreme obesity present in a woman's brothers considered a defect that should be taken into account when marrying, and does it fall under the meaning of "choose carefully for your progeny"?

The religious criterion for choosing a wife is piety, as the Prophet, peace and blessings be upon him, said: "So win the one who is religious, and you will prosper." The Sharia has guided towards looking at the fiancée to achieve acceptance, so obesity is not a defect that prevents marriage to a woman who possesses it. It is a relative matter that differs from person to person and can often be treated. As for the hadith "Choose well for your semen," its meaning is to choose a pure origin in terms of religion and character. It is advised to perform Istikhara (prayer for guidance) and rely on Allah, for success lies in choosing a religious woman.
