When an insulin needle breaks inside the body, it is advisable to seek immediate medical attention. When an insulin needle breaks inside the body, it is important to go to the hospital at the first time to have it removed. Since insulin needles are relatively small, they usually do not cause any obvious sensation when they break inside the body. However, the needles tend to move away from the original injection site and wander around the body tissues under the movement of the body, which may injure important organs or blood vessels. Therefore, if an insulin needle breaks inside your body, you should seek medical attention immediately. If the end of the broken needle is visible to the naked eye, it can be removed with tweezers and cleaned. If it is not possible to locate it accurately, it is necessary to check it with the aid of X-rays and then remove it with the help of surgery. Insulin needle breakage is usually related to the way of injecting the needle after injection and long-term repeated use. The needle should be withdrawn slowly and gently, preferably vertically, to avoid offsetting the needle with force. Insulin needles should not be reused for long periods of time, as this increases the risk of needle breakage and can also lead to an increased risk of infection. When using insulin, be sure to follow your doctor’s instructions strictly.
