When the diameter of the fistula is enlarged, it is known as stretching of the piercing. In such a situation, the tissue stretches to such an extent that the user can wear jewelry having a larger gauge. The area where the piercing is done affects its wellbeing and the degree to which stretching would take place. In case the piercing is near the edge of the tissue and it enlarges, the skin at the edge tends to thin out. Sometimes, this skin becomes so thin that blood circulation does not take place. The tissue tends to die, due to which the skin becomes weak and can tear. If this happens, the user should go to a physician to get the torn skin stitched together in order to help it heal appropriately. In certain cases, another stretch occurs soon after one stretch has healed. The tissue splits and it may lead to a 'blow-out'. A 'blow-out' refers to a stretching of the tissue which does not heal to regain its original thickness. It is called a 'blow-out' because its appearance is that of a tissue flap that is away from the fistula. When this happens, the user should replace the jewelry to something of a smaller size or remove it at once. This would help the tissue to heal soon. Along with this, the use of pure olive oil or vitamin E cream that is rubbed on the flap would also accelerate the healing process. The process of stretching the piercing should be done slowly. It should be done keeping in view the process of healing of the piercing. If the stretch is rigid and sore, it should be given some time to adjust before trying to stretch it. The elasticity of skin is different for different people. The time taken for the stretching to take place may vary from one person to another. While stretching the piercing with weights, care should be taken to ensure that the fistula is not stretched overly, that is stretched to a diameter of more than 12/14 mm. However, what diameter can be called overstretching depends on the initial diameter of the piercing. If overstretching happens, the tissue might tear, which would necessitate stitching to help the area to heal. The tissue itself might be greatly damaged to an extent that it cannot heal to the desired level or might lead to damage to the tissue in case of stretching in future.
