Worsening your health conditions
If you have a preexisting medical condition, splurging on the Super Bowl may not be the best idea. People with previous health conditions can eat their ways into serious health problems, particularly for diabetics, cardiac patients, and patients with GERD. For example, in the hour after eating a big meal, the risk of having a heart attack jumps 10 times, risk that is much higher for people who had heart disease, according to Balger.
That's because after a large meal, a significant portion of blood goes to the gut to aid digestion. This blood has to come from another place, so if you have narrowing blood vessels or problems with blood flow, that could precipitate a heart attack.
