Hi there!
While the root like think could undigested plant matter, since this was a single episode it may not be anything to worry about. Flatulence could occur due a few causes such as stress, aerophagia, gastroesophageal reflux, malabsorption syndromes, lactose intolerance, GI infections/ parasitic infestations, increased dietary intake of oligosaccharides, dairy products beans, lentils, onions, garlic, scallions, leeks, turnips, rutabagas, radishes, sweet potatoes, potatoes, cashews, oats, wheat, cauliflower, broccoli, cabbage etc. You could start by making changes in your diet. If this does not seem to help, I would suggest consulting a gastroenterologist for an accurate diagnosis and appropriate management.
Hope this helps.
Take care!
So my question is, is this normal? Is something really wrong? What can I do about it until I go to the doctor?
