No, burping does not invalidate wudu (ablution).
While burping releases gas, which might seem to nullify wudu, Islamic scholars generally agree that it doesn't. The focus in wudu is on purification from specific impurities or actions, and burping is not considered one of them. It's a natural bodily function and doesn't render one impure.
However, persistent burping might indicate underlying health issues. It's advisable to consult a doctor to address excessive gas, as maintaining good health is also important in Islam. Remember, seeking medical treatment is encouraged.
In summary, you don't need to renew your wudu after burping. Focus on maintaining good health and consulting a doctor if you experience excessive gas.
