As indicated earlier, many pain relievers can cause stomach bleeding. This is why it is advised to always consult your doctor. Doctors will prescribe a strong pain reliever and you will also be given an effective stomach protector by the pharmacist. However, people tend to be very ‘easy going’ when it comes to painkillers. These are usually bought over the counter from a chemist and the heavier pain relievers such as Ibuprofen and Advil can definitely cause some damage to your stomach and intestines over time. This in turn makes you more exposed to the risk of internal bleeding. On the Next page you can read more about the possible causes for anaemia.
