Why a person can’t have heavy meal before swimming?

 

According to the myth, eating diverts blood toward the stomach and away from the muscles, resulting in paralyzing cramps. Inadequate blood supply can cause muscle cramps. And it turns out that when we eat, the body does divert extra blood to our stomach; when we exercise, our muscles also get extra blood. But the change in blood supply after chowing down on a sandwich isn't severe enough to result in a medical emergency. In other words, muscle cramping due to low blood supply just doesn't happen in healthy people. Instead, it usually indicates an underlying medical condition, such as arteriosclerosis, a condition that occurs when a person's artery walls narrow and harden.

Swimming shortly after a meal isn't risky at all. 
Swimming, because digestion diverts some of your blood flow from your muscles to your stomach, was feared to block that vital blood flow, resulting in severe cramps and the risk of drowning. 
Another variation of the myth suggests that your limbs will not receive enough blood flow because your stomach diverts it, leading you to drown. 
These fears are unfounded because your blood isn't diverted nearly enough to cause any serious issues. 
There have been no known deaths as a result of swimming on an empty stomach.
