What does sickling mean?
Sickling most commonly denotes a process affecting red blood cells. In sickle cell disease, abnormal hemoglobin causes cells to become rigid and curve into elongated, crescent-like forms. These cells can obstruct small blood vessels, reducing blood flow and causing pain or tissue damage; their changing shape is therefore an important subject in diagnosis, treatment, and medical research. The word can also refer to the older practice of cutting grain with a sickle, a curved hand tool, though this use is now largely literary, historical, or regional. In phrases such as “prevent sickling,” the word plainly describes a cell deformation rather than the act of harvesting. Although it may sound dramatic, sickling is a precise term in hematology. Its striking double meaning also links a modern medical condition with the agricultural tool whose curved shape gave the phenomenon its name.
The process by which red blood cells become rigid and sickle-shaped, especially in sickle cell disease; also, the act of cutting crops with a sickle.
"Sickling can cause pain and tissue damage when affected cells obstruct small blood vessels."
The medical sense is technical; the harvesting sense is uncommon and somewhat literary.
To cut grain or other crops with a sickle.
"The laborers spent the morning sickling the wheat."
This use is traditional and mainly literary, historical, or regional.
Undergoing or causing the deformation of red blood cells into sickle shapes.
"The researchers examined sickling hemoglobin under low-oxygen conditions."
The adjectival use is primarily technical and occurs in hematology and biomedical research.
Sickling takes its name from a farming tool because rigid red blood cells can take on a similarly curved, crescent-like shape.

Etymology of sickling
The word is formed from “sickle” plus the suffix “-ing.” The English “sickle” was attested in Old English as “sicol,” and cognate forms occur in other Germanic languages, including German “Sickel” and Dutch “sikkel.” The medical use developed by applying the name of the curved agricultural implement to the similarly curved shape assumed by affected red blood cells.
How sickling is actually used
In medicine, the term is technical and most often appears in discussions of sickle cell disease and related blood-cell disorders. Its agricultural sense is now uncommon and sounds formal or traditional.
