I get hiccups when I'm "full" every single time I eat. I've learned to eat VERY slowly and as soon as the first one comes, I stop eating. The rare times I've tried to eat past that point, I've been miserably sick. Runny noses, sneezes, and other odd "symptoms" can be full queues for WLS patients due to the anatomical changes made in the vagus nerve during surgery. Totally normal and for most people it goes away with time. But it can be a really helpful benchmark for learning your new body, so I would say slow down and allow time between each bite to see if/when the hiccups trigger.
