The main mistake is eating dry chia seeds without soaking them first.Dr. Sethi explains,“You have to soak your chia seeds, or you risk this happening inside your body. I'm a gastroenterologist. People have ended up in the hospital after eating dry seeds and then drinking water. The seeds expanded and got stuck in the esophagus, and it had to be removed endoscopically. Even though it is rare, it has happened in people with swallowing issues or other GI conditions”, as stated in the report by TOI.
If not soaked overnight, chia seeds could almost turn fatal, with almost 27 percent water soaking capacity. Doctors say that having unsoaked chia seeds could multiply their numbers in your stomach.
The gel-like structure formed after soaking chia seeds can be consumed directly, says Dr. Sethi according to TOI, and should be started with one teaspoon. The dose can be gradually increased with time
