Capillaries can face several issues, including blockage due to blood clots or plaque buildup, which can impede blood flow and lead to tissue damage. Additionally, capillary permeability can become altered in conditions like inflammation, allowing excessive fluid leakage and contributing to edema. Diseases such as Diabetes can also weaken capillary walls, leading to complications like retinopathy or nephropathy. Lastly, capillary fragility can increase with age or certain medical conditions, making them prone to rupture and resulting in bruising or bleeding.
