Ogenki desu ka means "How are you?" or "Are you well?" This is a polite way to ask about someone's well-being. It's often used when greeting someone you haven't seen in a while, or to show concern. For example, after seeing an old friend, you might ask, "お元気ですか？最近どうですか？" (How are you? How have you been recently?).

相手の体調や様子を尋ねる丁寧な表現です。久しぶりに会う人に使います。「お元気ですか？」
