"Olethros" (G3639) is a Greek word found in four NT verses and is translated as "destruction."
In 1 Corinthians 5:5,scripture describes the destruction as destruction of his flesh. However flesh can refer literally to our physical body, or figuratively to our fleshly desires, or sinful nature. Ten or so English translations go with sinful nature, and the rest go with physical body of flesh.
In 1 Thessalonians 5:3 refers to the "sudden destruction" of non-believers when the "day of the Lord comes" as believers are not destined to wrath. Thus the sudden destruction refers to being consigned to Hades and Gehenna upon physical death.
In 2 Thessalonians 1:9 the lost pay the penalty of "eternal destruction" away from the presence of the Lord. Thus consignment to Hades and Gehenna seems to be in view.
In 1 Timothy 6:9 the lost plunge into "ruin" and "destruction" with the NASB translating our word as ruin.
Physical death results in the destruction of our physical body, at least until the first or second resurrection where the lost face the second death in the Lake of Fire.
Clearly the last three examples fit the idea of physical death followed by spiritual torment in Hades and the second death in the Lake of Fire.
Which brings us back to arriving at an understanding of 1 Corinthians 5:5:
I have decided to turn such a person over to Satan for the destruction of his body, so that his spirit may be saved on the day of the Lord.
Here we see that physical death is not in view, but the separation from the comfort of thinking you are saved, such that perhaps the person will "come to their senses" as the Prodigal Son did, and return to the love of God.
