'''Anemia sel sabit''' adalah kondisi serius di mana [[sel darah merah|sel-sel darah merah]] menjadi berbentuk [[bulan sabit]], seperti huruf [[C]]. Sel darah merah normal berbentuk donat tanpa lubang (lingkaran, pipih di bagian tengahnya), sehingga memungkinkan mereka melewati [[pembuluh darah]] dengan mudah dan memasok [[oksigen]] bagi seluruh bagian tubuh. Sulit bagi sel darah merah berbentuk bulan sabit untuk melewati pembuluh darah terutama di bagian [[pembuluh darah]] yang jadi menyempit dengan sendirinya, karena sel darah merah ini akan tersangkut dan akan menimbulkan rasa [[nyeri]], [[infeksi]] serius, dan kerusakan organ pada tubuh.▼

| caption = Gambar A menunjukkan sel darah merah normal yang mengalir bebas melalui pembuluh darah. Sisipan menunjukkan penampang sel darah merah normal dengan hemoglobin normal. Gambar B menunjukkan sel darah merah abnormal berbentuk sabit yang menempel di titik percabangan dalam pembuluh darah. Gambar sisipan menunjukkan penampang sel sabit dengan untaian hemoglobin sabit (HbS) polimerisasi panjang yang meregang dan mengubah bentuk sel hingga tampak seperti bulan sabit.
