Soluble and insoluble fibres occur in plant foods and support different aspects of digestion. Soluble fibre forms a gel; insoluble fibre adds bulk and holds water.
Fibre can affect stool consistency and bowel movement when nerve control changes after SCI. Slower intestinal movement can contribute to constipation and harder stool.
There is no universal ideal intake after SCI; higher amounts can worsen symptoms for some. Evidence is limited, and general population recommendations may not fit SCI needs.
Whole plant foods provide fibre alongside other nutrients; supplement benefits are less certain. Fruit, vegetables, legumes, and whole grains offer varied fibre sources.
