Latar Belakang: Gastroenteritis sering menyerang balita dan anak–anak karena daya tahan tubuhnya  yang masih lemah, sehingga dapat terkena bakteri penyebab diare seperti muntah berkelanjutan yang akan meningkatkan dehidrasi (kekurangan cairan). Gastroenteritis seringkali diikuti dengan adanya dehidrasi, baik dehidrasi sedang sampai dehidrasi berat. Gastroenteritis akut menjadi salah satu penyebab kematian anak terbesar di dunia. Hasil dari beberapa penelitian ditemukan bahwa pemberian suplemen zink dan selenium dapat mempersingkat waktu penyembuhan atau durasi rawat pasien dengan gastroenteritis akut. Tujuan: Untuk mengkaji dan menganalisis peran selenium dan zink dalam proses pengobatan gastroenteritis akut pada anak. Metode: Menggunakan metode literature review dengan menelaah artikel jurnal berjumah 10 artikel dengan 8 artikel yang membahas tentang peran zink dalam proses penymebuhan gastroenteritis akut pada anak dan 2 artikel yang membahas tentang peran selenium dalam proses penyembuhan gatroenteritis akut pada anak. Ulasan: Hasil telaah menunjukkan bahwa selenium mengandung enzim yang dapat menurunkan stres oksidatif sehingga berperan dalam proses penyembuhan diare akut. Sedangkan, zink dapat membantu proses penyembuhan karena meningkatkan penyerapan cairan dari usus, membantu pembersihan organisme, dan mendukung regenerasi dan integritas mukosa, dan memiliki mekanisme yang berhubungan dengan kekebalan. Kesimpulan: Pemberian zink dan selenium dapat mempercepat penyembuhan gastroenteritis pada anak.
