Parents say their 4-year-old son died nearly one week after he went swimming in Texas.
Francisco Delgado III complained of an upset stomach after going swimming at the Texas City Dike over Memorial Day Weekend, but his parents didn't think much of it.
But days later, the Delgados realized something was wrong with their son.
The boy was experiencing symptoms of a stomach bug, including vomiting and diarrhea for several days. On Saturday morning, Delgado said his shoulders were hurting.
"Out of nowhere, he just woke up. He said ahhh," Delgado's father, Francisco Delgado Jr. told KTRK. "He took his last breath and I didn't know what to do no more."
The boy died Saturday at the hospital from the condition known as dry drowning.
Dry or secondary drowning occurs when someone breathes water into his or her lungs. It occurs more prominently in children, but can also happen with adults.
In dry drowning cases, the water causes vocal chords to spasm and close, shutting off the airway and making it hard to breathe. With secondary drowning, the airways open and let water into the lungs, causing pulmonary edema, which is when fluid builds up and makes it difficult to breathe.
Symptoms of secondary drowning can occur anywhere from hours to days after a person inhales fluids.
